Solar Power International 2016: Industry Latest and Greatest

Every September we pack our bags and head to the largest solar conference and exposition in the country; Solar Power International. This is when we get to connect with the broader solar community, advocates, and friends working far and wide for the betterment of the world through distributed clean energy. It is also the time when manufacturers unveil their latest technologies. These technology improvements come fast and furious in an attempt to stay ahead of the curve in a competitive industry. Just two years ago when I started working with Run on Sun we were able to get 270 watt panels from LG. What is coming from them in the next year will blow your mind. Here is my run down of the top take aways from SPI 2016…

Panel: “Survival of the Fittest, the Future of Residential Solar”

Some of you may have seen the three part series Run on Sun’s CEO, Jim Jenal, wrote recently about what we need to do to be sustainable as an industry facing a crisis of increasingly shoddy workmanship and shady business practices. As part of the convention’s educational program, Jim was invited to participate on a panel of solar professionals to discuss the future of residential solar. The panel consisted of a wide range of backgrounds including a representative from a national company, Sunrun’s Michael Grasso, Rick Luna from a municipal utility CPS Energy, Ed Murray from a medium sized company, Aztec Solar, as well as national advocacy group SEIA, and Jim representing the small installer at Run on Sun. 

The panelists discussed their take on who will dominate the residential solar space and what will the predominant business model be in five years. This was a perfect platform to raise the very real issues of quality facing the industry and Jim did not disappoint! Of course Sunrun’s Grasso asserted that national scale companies continuing the leasing model with storage will dominate in the future. But there were many nods of agreement in the audience when Jim insisted that the current status quo is not sustainable. Giant publicly traded national companies operating in the red and pushing customers into bad deals are going to cause a backlash. We’ve already seen many law suits and bankruptcies in the industry. Solar City’s Better Business Bureau rating in the Bay area is an embarrassing 80% negative. The notion that Ed Murray, from SEIA, put forth that the market will naturally take care of the bad companies is just not a sustainable way forward or an ethical one. As more and more consumers get hit with bad contracts and solar systems, the market will be left with a bad taste for solar. The people in this industry who are doing it for the right reasons, aiming to help people save money and reduce their impact on the ecosystem need to demand that there is more oversight over the quality of systems and some legal standards around contracts.

Jim’s comments seemed to be well received in the audience as most people attending were people who work in solar for the right reasons given they are investing in the hefty price-tag to attend the convention. But the disparate opinions on the panel itself was interesting to say the least. I don’t know if the reps for big companies are just out of touch with what is happening on the ground or if they are in denial. 

Everyone agreed that a future will include storage or other bundled options for improving home efficiencies. However, Jim noted that storage needs to be presented to clients in a transparent way so they understand the true value of storage and whether it makes sense for them or not. If you are on a tiered rate system with no demand charges there likely is no value in storage. Solar stakeholders from advocates to installers need be fostering business practices that focus on transparent education for consumers instead of just closing every sell if we are to survive as an industry and continue to grow solar as the incredibly valuable resource that it is. 

 

LG Solar Panels Up the Ante 

We have been installing exclusively LG panels since 2012. Why? We believe LG panels are the best for our clients for two main reasons. 1. As a diversified company we, and our clients, can rely upon them to stick around to back their 25 year warranty no matter what happens in the wider solar industry. And 2. LG has an incredible R&D department churning out ground-breaking improvements keeping them at the top in both quality and output year after year. 

Last year LG announced 320 watt panels would be coming and we were fortunate to be one of the first to install these at a beautiful home in Altadena last Spring. This year they have several incredible new announcements:

  1. LG 355 Black on BlackNeon R Panels: This latest generation of LG panels has incorporated rear contacts, so no wire lines showing on the front of the panel. They displayed an impressive 365 watt panel slated to be released in Q1 of 2017! The “R” will also be available with a black backsheet and a 355 watt output capability. With rear contacts and a black backsheet the panel has a seamless sleek look like no other! (see pic)
  2. AC Modules: LG is partnering with Enphase Energy to incorporate Enphase’s newest generation of microinverter into the panel itself, creating an AC solar panel. Panels convert sunlight into direct current (DC), then that current must be converted into alternating current (AC) using an inverter. With the inverter directly on the panel, this will simplify things on the roof a great deal. As the majority of our projects are with Enphase microinverters and LG panels, this is a match made in heaven!  
  3. Bi-Facial Panels: Bi-facial panels have no back sheet, allowing reflected light to hit the panel from underneath when installed above a light surface adding to the output capacity of the panel. They had these on an impressive display showing up to 40% more output than a standard panel with a backsheet. There has been a limited market for bi-facial panels historically. Sometimes you see them on shade structures, but the price point is higher than standard panels. These new LG panels are in a commercial 72-cell format so they are aiming to capture commercial projects that can really bank that extra output capacity. 

 

Enphase Energy Total Rethink

Enphase MicroThe Enphase booth was seriously hoppin’ throughout the expo! Unsurprisingly with a total redesign of their system from the microinverter to the cable and even a special junction box.

  1. IQ 6 Micro:The new system, called IQ, includes the same microinverter guts with a new, double-insulated, polycarbonate case eliminating the need for a ground wire and cutting down significantly on weight and cost. The new IQ inverters will pair with a broader range of panels including 60-cell and 72-cell commercial panels as well as up to 400 watt panels.  
  2. Cable: The new cabling will be lighter and cheaper as well because they are carrying 2 wires compared to the current cable carrying 4 wires. They eliminated the need for a neutral for communications as they will now communicate on the same lines that the energy is transported. They also eliminated the need for a ground wire due to the new polycarbonate case.  
  3. Smart Junction: Lastly they rolled out a junction box wired up for easy installation between the string of panels and the run to the electrical service. 

All of these improvements come together to create a system that includes the microinverters we know and trust at a lower cost with a simpler and quicker installation. 

 

Everest Solar Racking Shares at SPI

EverestThe large majority of Run on Sun’s solar installations are being held together by the great racking products from Everest. This is because their materials are the most solid and well thought out racking product for standard pitched roofs on the market today. Their booth at SPI included a new “shared rail system” which allows two panels to come together on a single rail cutting down on the total number of rails needed for an installation. This system incorporates the same beefy product we trust with a reduced overall cost and installation time on the roof. It also doesn’t hurt that the entire team at Everest Solar Systems are great people and local to SoCal too! 

 

Edisun Dual Axis Tracker - PV Booster

Idealab tracker

Pasadena’s Idealab, an incubator, has been consulting with Jim on a revolutionary new product - the PV Booster - at their start up Edisun. They unveiled their dual axis tracker system at SPI. The system is designed for large flat roofs (and even carports) and potentially can increase output by up to 40% by tracking the sun throughout the day.

We were excited to see the system on display as they have developed quite a bit over the last six months of consulting with Jim. There was a lot of interest in the system at the show and we hope to help move their vision forward by installing some projects using their system locally here in Pasadena in the coming year. 

 

A Solar Wedding

SPIdoEvery year Run on Sun participates in Solar Fred’s Tweetup. It has become an event of close friends and allies. This year was a very special Tweetup as mainstays Pam Cargill and Martin Hamon got hitched in a truly extraordinary ceremony! Pam was walked down the “aisle” by a mascot Sun to the tune of “Here Comes the Sun". The ceremony included as many solar-love metaphors and quips as possible as Reverend Solar Fred officiated. Apologies for my blurry photo but it really was an event to remember. If you have pics to share with the happy couple you can share them on their dropbox here and relive the moment on Twitter with #SPIdo.

Intersolar 2015 Preview

Intersolar North America 2015 (IS) kicks off this week in San Francisco, and as we have for the past several years, Run on Sun will be there to learn, to mingle with the rest of the Solar Tribe, and yes, to party!  Here’s our preview (with more to come after the show).

Coming Attractions?

One of the biggest attractions of IS, the exhibition floor is crammed with every solar-related product and service imaginable (and some you wouldn’t have believed until seen!).  Here are some of the things we are actively looking for as we roam the floor (and it really is a “we” this year as Laurel and Josh will be attending as well!)

Craving for Saving (Energy)

Craving saving energyWe have been writing about, and longing for, viable energy storage solutions for as long as we have been attending IS. While the hype around storage has only grown exponentially since, the number of viable products still remains depressingly thin.  Will this be the show when that finally changes?

Number one on our cross-your-fingers list is the previously announced, but not yet available, storage offering from Enphase Energy.  Given that we have a whole lot of Enphase systems in the field, and a client-base that is rapidly shifting to time-of-use rates, the Enphase product, if it is a product, would be huge.  While the timing would surely be right, our anticipation is amped-up by the knowledge that Enphase will have a booth at IS (a first for them, to our knowledge).

Interestingly, neither SolarCity nor Tesla is listed among the exhibitors as of this morning - I guess we won’t be seeing any Powerwalls on display.

Bigger, Better, Soon?

Beyond storage, manufacturers are always touting their bigger, better products at the show and this year should be no different.  Of particular interest in that regard is the potential release of a slew of new, larger module options coming from our favorite solar panel maker, LG.  We have seen the hints on this front for sometime now as the CEC approved list of LG modules includes units as large as 325 Watts - compared to the LG 305’s which are presently the largest thing we are seeing in distribution.  So will we now have multiple options for higher efficiency, higher output panels from LG?  And if so, when and at what cost? 

Meanwhile, Enphase appears poised to announce a new microinverter product, the S280 (just in time to pair with those higher power LG modules?), as it too now appears on the CEC list.

We know that we have clients eagerly awaiting these developments - watch this space!

Rack me Up!

Racking solutions continue to be an area where the cleverness of the design rarely survives the realities of the roof.  We are constantly exploring new approaches for difficult problems such as viable ballasted systems (that will be accepted by AHJ’s like LA City and County) and structure suppliers for the growing interest in carports, pergolas and the like.  While we have worked with a number of companies in this area, we are still on a quest for solutions that not only look good on paper, but that our installers can grow to love.  We will be prowling the floor of IS with that as our number one must have.

We should note, however, that we remain quite pleased with Everest Solar as our pitched roof solution, and that view was enhanced by the long-awaited release of their UL-2703 listed end and mid-clamps.  The inspectors who have looked at that system on the roof have been quite impressed with it, as are we.

Party Time

It wouldn’t be IS without the opportunity to reconnect with old friends and, hopefully, make some new ones amidst the Solar Tribe.  After all, these are people who work every day to make the world a better, cleaner, more sustainable place.  They are a great bunch of folks and we are honored to be counted among ‘em!

First up is the Tweetup, hosted once again by solar celeb, Tor - @SolarFred - Valenza, with backing from @Enphase, @RECSolar, and @Grid.  This has turned into an annual, and eagerly anticipated event, and we thank in advance Solar Fred and friends for making this happen.

Did you see what they had at XYZ booth?Then comes Summerfest, a huge gathering of folks with lots of different types of food and drink and great views of the downtown San Francisco skyline.  Summerfest is a great place to exchange views of what was on display on the exhibition floor, and to plot strategy for the next day, as in, “Did you see what they had over at the XYZ booth?  It was amazing you have to check it out!”

But it is Wednesday night that really crowns the show.  Starting with the great afterparty/pre-SBOB party thrown by Impress Labs - thanks to Solar Curator Tom Cheyney for hooking us up - we are able to get warmed up for the main event - the Solar Battle of the Bands!  For the first time ever we are heading into the show knowing where are ducats are coming from - thanks to Jessica over at Solar Power World for the connection!

It is going to be a busy week, and we look forward to learning a lot.  Look for our recap of the show next week!

Open Letter to LG: Life's Not So Good!

When I was a kid, my Father subscribed to something called the Reader’s Digest, a magazine that excerpted articles from a variety of publications and compiled them into one, convenient, pre-Internet source.  A very handy source except for one downside—the publisher’s penchant for promoting never-ending contests.  Every week our mailbox would be besieged with yet another fabulous opportunity to win something grand—just fill this out (and maybe subscribe to yet another magazine?) and you, too, could win the prize of a lifetime.

Finally, my Father could abide the deluge no more. He famously (at least within our household) wrote to the subscription department and threatened to cancel his subscription if they would not halt their assault.  As he put it, “Either finally give me the Moon, or leave me in peace to buy my own green cheese.”

Which brings me to our friends at LG.

We love solar modules from LG; in fact, we have been using them exclusively since 2012.  We installed the first of their NeON modules anywhere in the world, and LG are the only solar modules that you see featured on our website.  We are absolute fans, and so are our clients.  We consistently deal with folks who want to maximize the amount of power on their roofs and the 300 Watt NeON modules are the way to go.

Except for one thing… we can’t get them.

Despite getting emails from LG on a weekly basis, with messages like this one:

 Please sell LG's NeON modules…the NeONs are not available for love or money.

So, no, the LG MonoX NeON is not the right module for us since it makes no sense to sell a job with a product we cannot get!

From what we hear, it is like this all across the country.  A friend and colleague of ours in PA had tweeted about a project he just completed—with LG 300’s!  So we asked him about it and he replied: “I lucked out on this batch, LG300s are just a rumor anymore. Back to Solar World 275s for now.”

Ouch.

Just the other day we got an email with this banner across the top:

When will we get these?

(If we were to caption this photo it would be something like, “We will be getting these WHEN?  Uhnnnh. Thud.")

 Let’s be clear:

It is NOT reliable to market a product to installers and then not make the product available.

It is NOT reliable to build a network of installers across the country who have faithfully and enthusiastically promoted and installed your modules, only to leave them with six month delivery times for your product.

And it certainly is NOT reliable to urge us in constant emails to sell, sell, sell, when you know full well that you aren’t going to be able to deliver on those sales.

It is not reliable at all.  The word you are searching for is: disrespectful.

So here is the question for our friends at LG: What are you going to do about it?  Frankly, until you are ready to provide reasonable delivery times for module orders, we really don’t need to see any more emails touting what a great partner you are. 

Either supply us with product in a respectful manner or leave us alone. 

We’ll buy our cheese somewhere else.

On the Roof - Installing Solar at Westridge - Part 4

Our first three installments saw us secure our rebate reservation, successfully pull our permits, and deal with a host of challenges on the ground.  But now the real fun starts - in this episode we will document the heart and soul of this project, “Up on the Roof!”

Projection

Solar projects actually begin on a computer screen as the designer tries to map what is known about the roof, the utility service, and the client’s needs into a coherent proposal.  As the project progresses through the rebate and permitting processes, that design is refined - and as we have seen, sometimes altered.  But the trick of any implementation is to go from the designer’s plan to an actual system on the roof - starting with getting the attachments in place.

Jim and Brad confer over the plansNearly ancient methods, tape measures and chalk lines, are the essential tools in this process.  Since a solar array is essentially a grid, the trick is to project what is on the plans into a corresponding grid on the roof.  Precision and accuracy are the key to making this work, but roofs are notoriously inconsistent places!  What seemed to be square, isn’t always.  What appeared to be flat, actually has its own peaks and valleys.  While our projection onto the roof proved easy enough, we were about to discover that what you see - or were told - isn’t always what you get!

There’s What You Plan and What You Get

Our biggest design challenge had been the need to account for the somewhat unusual roof construction that we had to accommodate.  In particular, our underlying roof structure was a  20 gauge, type B steel deck, overlayed with multiple layers of plywood, foam insulation and roofing materials.  Given the thickness of those layers we had determined that we would need to use four,  8-inch-long, self-tapping screws to secure our “FastFoot” anchors to the roof.  We had purchased hundreds of those screws - along with a top-of-the-line Hilti cordless driver - to do the job.  But something wasn’t right.

As we started making our first few attachments it was clear that not all of them were reaching the steel deck!  Apparently in some places the actual thickness from the roof to the deck exceeded the 8″ reach of the screws.  Visual inspection from a scissors lift inside the building confirmed what we suspected - clearly not all of the screws were penetrating the deck, yet in other places, all four screws penetrated without difficulty.  There was only one solution to the problem of our inconsistent roof - longer screws!

Fortunately, we were able to order some 9″ screws from the manufacturer - the longest that they made.  They did the trick - now we could be certain that every FastFoot plate was properly secured.

Lean on Me

The changes to our plans imposed during the permitting process meant that we were very tight on space.  At the top of our array we had to install 3 sub-panels, each of which had to handle three branch circuits that made up that sub-array.  Our original plan was to build a triangular cross brace out of unistrut to support the sub-panels.Sub-panel with braces Unfortunately, given our close quarters, the solar panels needed to come right up to the supports for the sub-panels - a cross-brace system would take up too much space.

Instead, we designed a set of steel braces that were bent at precisely the angle that we needed - 103° - to allow our sub-panels to be perfectly vertical on our 13° sloped roof.  The design was easy, but could we get them fabricated fast enough to keep the project on track?  We knew of a small metal shop near our offices and we took the design to them - yes, they said, they could produce the six parts that we needed for $100 and they would have them in the morning - would that be soon enough?!!!

This turned out to be a very elegant solution to our problem.  Using two FastFoot anchors, we attached unistrut to them and then bolted our braces to that.  When combined with the rigid conduit feeding the sub-panel, we ended up with a very solid solution. 
Next problem!

Need a Lift?

The roof of our building was reachable by a series of three ladders traversing three different roof levels.   Josh delivers Enphase micro-inverters to the roof via boom liftWhile this was acceptable for getting personnel to and from the roof, it would never work for transporting hundreds of feet of rails, to say nothing of 209 solar panels!

Enter the boom lift - the same one that was unceremoniously dropped off for us by parking it under a No Parking sign!

Whether transporting rails, solar panels, or the Enphase micro-inverters as you see in this picture, the boom lift provided us with an efficient means of moving large amounts of gear up to our work site on the roof.  Operating a device that articulates in multiple dimensions in relatively tight quarters takes skill and great attention to detail.  (It also makes for some pretty cool looking photos!)

Connect the Dots

Once the rails were installed, the Enphase micro-inverters could be mounted and the process of running a continuous ground wire and the creation of the Enphase map could begin.

Ready for panels

Since this was an Enphase system, we would be able to monitor the performance of the array down to the individual solar panel/micro-inverter pair.  (Indeed, this monitoring ability was a key selling point for the system to the school as it nicely meshed with the school’s educational mission - more on that in our upcoming video!)  Each micro-inverter has a serial number that was carefully peeled off and affixed to a “map” that showed where each inverter was located on the roof.  As part of the commissioning process, we transferred the map data onto the Enphase website and built a true representation of how the system was laid out on the roof.

Now all we needed was to install the solar panels themselves!

Ralph and Josh installing panels

Careful attention to detail during this last step is rewarded with an array that aligns precisely and fits as planned.  Using the Enphase Envoy and a laptop computer, we could verify that each and every panel was properly connected and functioning as expected.  We could be confident that there would be no surprises that would need to be resolved later!

That gave us one last task for the boom lift - finished photographs.  Here’s our favorite:

Westridge PAC roof - solar project installed

Three inspections later - fire, building & safety, and PWP - and we were ready to officially go live.  Here’s how the system appeared on the Enphase Enlighten website one recent sunny day:

Westridge PAC solar system performance

The students at Westridge will be able to analyze the performance of this system for years to come, providing a first hand experience of how renewable energy works and can make a difference in our lives - what a great lesson to learn!

Chapter the Last

Which brings us to the end of this series - almost.  In our final installment you will see the video that we have produced for this project and you will hear from the Head of Westridge School, Elizabeth McGregor, Facilities Director Brian Williams, and three wonderful students talk about how this project plays into the larger mission of the school.  You won’t want to miss it!

On the Ground - Installing Solar at Westridge - Part 3

In parts 1 and 2 of this series, we documented what went into securing the rebate reservation and the process by which we secured our permits.  Now the actual work could begin - and that work starts on the ground.  So in this Part 3, we will look at the staging that was required for this production and take a close-up look at some of the heavy lifting that was needed far below the array itself.

A project the size of what we were going to install at Westridge - 52.3kW - involves thousands of parts, all of which not only must go together properly for the system to work and be safe, but they must arrive in a timely fashion!  For example, here’s just a sample of the parts that were needed for this job: hundreds of FastFoot plates, thousands of screws, hundreds of flashings, standoffs, and flange connectors, dozens of rail sections, mid-clamps, end-clamps, ground lugs and splices, to say nothing of 209 micro-inverters and solar panels!  Collectively these products came from five different distributors in four different states.

Needless to say, not everything goes as smoothly as you might like when you are pulling together all of these pieces.  UPS likes to brag about Logistics, but we found some of their logistics to be highly illogical.  Such as their sending two shipments that were sitting in an LA warehouse on a frolic and detour down to San Diego for the weekend, instead of driving them the twelve miles up the road to our job site!

boom liftEqually baffling were the folks who delivered our boom lift to the job site late on a Friday evening without even a phone call and just parked it out on the street - in front of a No Parking sign!

Seriously…

Would you leave this…

 

No parking!

Here?  Right - neither would we!  (And yes, the keys were in it!) The unscripted appearance of our boom lift prompted a puzzled call from the facilies director at Westridge:

Brian: “Were you folks expecting a boom lift to be delivered?”

RoS: “Yes, they are delivering it tomorrow morning.”

Brian: “Well, it’s here - and they left it on the street next to a No Parking sign.”

RoS: (Eek!) - “Really?  We’ll be right there!”

Like I said, not everything can go exactly as planned, but soon enough, everything arrived and in good condition.

Our staging area was set with:

LG solar panels in staging area

LG Solar Panels

Enphase micro-inverters in staging area

Enphase Micro-inverters

Unirac rails in staging area

Unirac Solarmount (Evolution) racking parts

Lots of wire!

And lots of wire!

Transformation

Our first main task on the ground, now that everything was at hand, was to install our transformer.  This project required a transformer to step-down the voltage from the utility service (480 volts, three-phase) to the voltage that would be used by our micro-inverters (208 volts, three-phase).

Setting the Stage

Westridge transformerOur transformer was a 700 lb beast that had to be installed on a concrete pad (that we had to pour) in the equipment storage area on the East side of the building.  To secure the transformer to the pad, we would imbed bolts into the pad and then maneurver the transformer on top of the bolts and anchor it with washers and nuts.  Two key challenges there - first was to guarantee that our bolts were precisely positioned in the pad since the transformer gave us very little margin for error.  Second was to get the transformer in place on top of the bolts without damaging them.

pad prepWe solved the first problem by drilling into the existing concrete and securing our bolts into the ground with heavy duty anchors - as you see here with the framework for the pad surrounding them.

Then, when we were ready to fill in the form with concrete, we added some framing at the top to try and keep the bolts as plumb as possible, as you see here:

concrete being added for pad

The Big (Not So) Easy

That took care of problem number one, but what to do about problem number two? Now that the pad was dry, the challenge became getting our transformer into place.

ready for the transformer

Our solution would make any student of ancient cultures proud - we crafted a wooden platform over the pad and slid the transformer from its pallet onto the platform.  Then we lifted each edge, one at a time, and placed blocks of wood under each corner.  That allowed us to remove the platform and then begin lowering the transformer over the bolts by carefully removing a block at each corner.

Very little margin for errorAs we removed each block, the transformer came closer to the bolts protruding from the pad.  We could push the transformer - gently - so that it aligned with the bolts.  Ultimately, the last block was removed and the result was a complete success with just the right amount of angst along the way!

But as you can see, we really didn’t have much margin for error!

The Art of Conduit

In addition to our transformer, there were several other pieces of gear that had to be mounted on the ground including a 200 Amp sub-panel, two disconnect switches and a performance meter.  Linking them all together is the conduit through which our conductors would be pulled.

The art of running conduitPasadena requires rigid metal conduit (instead of EMT) to be used for solar power systems wherever it is accessible on the outside of a building.  That offers some additional safety, but it comes at a cost - especially given that we were using 1.25″ conduit for most of our runs.  Rigid conduit of that dimension is heavy and cannot be bent by hand.  Instead, a motorized pipe bender was the order of the day - and it took some really skilled craftsman named Don and Josh to get our conduit in place and looking good.

It really is an art, as much as a science, and when done with care and precision, the result is quite appealing!

Pulling it Together

Our final ground-based task was to pull the conductors through the conduits.  Our longest pull was 245′ - not quite a football field, but close!  Moreover, that longest pull had multiple bends as we routed the conduit to make it as invisible from the ground as possible.  (To complete the task of making the conduit “disappear” to the greatest extent possible, the client painted the conduit to match the walls and the trim!)

At the end of a very long, drizzly Saturday, we were rewarded with having our conductors fully in place from the utility disconnect switch and performance meter socket:

… to our disconnect switch adjacent to the transformer:

Our penultimate installment will take you to the roof where the real action takes place.  So buckle in, the next chapter isn’t for the faint of heart!
