From 'Glut' to Glory - Making Storage Work! ACTION NEEDED!

On Sunday we wrote about a growing problem in California: as we have increased the role of solar generation in our electric mix, we have found ourselves in the awkward position of having to occasionally curtail that production, or worse yet, pay neighboring states like Arizona to take our excess!  This is clearly not sustainable, but fortunately there is a fix in the works in the form of Senate Bill 700, and it just needs the support of the solar community to make it happen.  Here’s our take…

The Glut

Solar power output bell curveAs everyone knows, the production of a solar power system peaks at solar noon - on a cloudless day providing a nice “bell curve” for power output, like in this illustration from an actual, Run on Sun solar installation.  The problem is that the peak demand for electricity does not align with solar’s peak; rather, peak demand occurs much later in the day when folks come home from school and work and crank up the electrical devices that define modern living - giving rise to the dreaded “Duck Curve“.  If only - as our friend Carter Lavin ruminated the other day - there were a way to shift that energy in time from the solar peak to the demand peak!

Of course, there is such a way.  It is called energy storage.  Storage could provide that time-shift needed to make the most of our abundant solar energy.  So why aren’t we using it?

In a word - cost.  Today, energy storage systems are just too expensive, and the existing rebate system for storage systems, known as SGIP, is a joke.  The SGIP process, which is essentially a lottery, is no way to run a rebate program.  As we have argued in the past, for a rebate program to be meaningful, it has to be stable and predictable.  SGIP is neither.

The Glory

But this isn’t rocket science, and we have a relevant case study right before us - the California Solar Initiative (CSI) rebate program.  When CSI began, back in 2007, its 10-year mission was to dramatically grow the PV market in California and, in so doing, drive down the costs of solar.  Back when it began, Run on Sun was installing systems for $8.47/Watt.  By 2014, after CSI ran its course, our install price was down to $4.13/Watt - a reduction of 52% in just seven years!  CSI (along with the muni-rebate programs) helped to achieve that cost reduction by providing transparency and predictability that a lottery program cannot replicate.  Moreover, the CSI program was easy for even the smallest contractors to navigate, making the program available to all.  This is what is needed to bring storage prices down, drive exponential growth (and the local jobs that go with that growth), and stop the madness induced by our present power glut.

So how do we get there, if SGIP is not the way?

Glad you asked - enter SB 700 (Weiner, D-San Francisco), the Energy Storage Initiative (ESI) that would create a 10-year, $1.4 Billion rebate program along the lines of CSI, but for energy storage systems.  Here’s how CALSEIA describes the bill:

SB 700 would create a 10-year rebate program designed to grow the California local storage market and make storage more affordable for consumers. The rebates would step down as more storage systems are installed and economies of scale are achieved, thereby driving down the installed cost of the systems. Local energy storage enables the integration of large amounts of renewable energy, creates value for consumers by helping them save money on energy bills, and increases grid reliability.

“Thanks to the leadership of Sen. Scott Wiener, Californians are one step closer to taking control of their clean energy future,” said Laura Gray, energy storage policy advisor with the California Solar Energy Industries Association. “This bill would allow homes, businesses, schools and public buildings to use solar and renewable energy at all hours of the day and night. Using a combination of solar and storage, consumers will make the sun shine at night.”

The bill has already passed the California Senate (sadly, on a straight party-line vote), but it faces an important vote as early as July 5th in the Assembly Utilities and Energy Committee, Chaired by Pasadena’s own, Chris Holden.  This bill should have bi-partisan support given the urgent need to move to an all-renewables future, but for that to happen, Committee members (and the Assembly as a whole) need to hear from their constituents. 

If you are in Chairman Holden’s district (which includes all of Pasadena and Altadena) you can reach his office at: 916-319-2041 and urge him to support SB700

Otherwise, you can find out your member of the Assembly by doing a search here.

Together we can get this bill over the hump - watch this space!

Solar + Storage = $avings!

We have been waiting a long time for this moment, when we could finally say that we can offer a solar plus smart storage solution for our residential clients.  Well the wait is over, and if you act fast, there is even a sweet rebate available!  It is a complicated picture, so stick with us as we break this down.

Introducing the Enphase Energy AC Battery

Four Enphase Energy AC batteries installed

Four Enphase Energy AC Batteries

Regular readers of this blog know that we are big fans of Enphase Energy and have been installing their microinverters for years.  Given our history with the company, we were excited to be approached by Enphase to participate in their AC Battery “beta” install program, one of just a handful of selected installers in the U.S.  We selected the site of one of our largest residential projects for the beta, knowing that would give us great data to study over time (and you know how we love data!).  We really like the way the install turned out, nice and neat!

Let’s be clear about what this system is, and is not.  It is not a battery backup system.  It will not keep the lights on if the grid goes down.  It is an energy arbitrage system - it stores energy from your PV array for use later in the day when your rates are highest.  That means that this system isn’t for everyone; it is for folks who have a PV system (or want to install one!) and are subject to time-of-use (TOU) rates, which mostly means just some folks who are SCE customers.  (Important note to SCE customers - if you install solar after July 1st, you will be forced onto time-of-use rates.)

Each battery stores 1.2 kWh of energy and can discharge that energy at 280 Watts, giving a discharge time of 4.3 hours.  The beta install shown above is a total of 4.8 kWh and a discharge of 1.12 kW.

So how does this work? Consider SCE’s TOU rates - the cheapest energy (13.1¢/kWh) is from 10 p.m. to 8 a.m.  The next cheapest energy (16.6¢/kWh) is from 8 a.m. to 2 p.m., and 8 p.m. to 10 p.m.   The really expensive energy (a whopping 33.5¢/kWh!) is from 2 p.m. to 8 p.m. - precisely when most people are coming home from work or school, turning on the A/C, and lights, and the TV and on and on.  Ouch! 

But note that the peak time does not coincide well with the output from the PV array, meaning energy exported onto the grid during the day is worth half of what that same energy would be worth later in the day.

That problem is exactly what the Enphase AC Battery is designed to solve.  Each morning when the PV array “wakes up” it starts to power the local loads of the house.  As the system produces more power, excess power is routed to charging the batteries (instead of exporting onto the grid).  Once the batteries are fully charged, any excess power is then exported and the homeowner gets a net metering credit for that energy.  But now when we get to 2 p.m. and the energy rate kicks into high gear, any energy needs that cannot be met by the PV array is supplied by the energy stored in the batteries, thereby limiting the amount of really expensive energy that has to be purchased from the grid.

Here’s a recent day’s performance of the beta system (I told you the data was cool!):

Enphase AC Battery usage

The bright blue is energy from the array, the orange represents energy loads - pale orange is entirely offset, bright orange is drawn from the grid.  The green at the bottom shows the percentage of battery charge - sloping up between 8 a.m. and noon, constant until needed starting around 6 p.m., and then discharging to offset the household loads. 

At the top we see snapshot data from the 8-8:15 p.m. interval.  No power is available from the array (duh, it’s night!), but the house is consuming 533 Watt-hours of energy, with slightly more than half coming from the batteries.  (Hint - the system is entirely modular, so we could easily double the size of the system to completely cover those loads.)

Bottom line: if you are on a TOU rate, storage can really improve the value of your existing PV system.  (And because the Enphase storage system is “AC-coupled” it can be installed with any existing PV system!)

The SGIP Rebate Program

Which brings us to the Self Generation Incentive Program (SGIP) rebates.  Starting in April, rebate applications can be submitted for energy storage systems.  Much as the CSI rebate program had multiple steps over time, SGIP has five incentive level steps and how fast it steps down is tied to how large is the demand for rebates.  (We anticipate that the highest rebate level will be paid out almost immediately after the program formally opens on May 1.)  At this highest rebate level we would expect the rebate for each Enphase AC Battery to be roughly $430.

The competition for these rebates will be pretty fierce.  Fortunately, there is a dedicated carve-out of money for small residential storage systems, so all the money won’t be gobbled up by a few, super-large projects.  (Interestingly, priority will be given to folks living in what is known as the Western LA Basin Local Reliability Area - you can check to see if your zip code, which includes pretty much all of the Run on Sun service territory - is included by clicking here.)

The rebate is not limited to SCE customers; folks who are SoCal Gas customers (that means you, PWP and LADWP folks!) can also participate.

Go with the Pros!

Properly sizing a battery system to go with your solar array is a complicated process that requires technical savvy.  Dealing with the SGIP bureaucracy requires a sophisticated team that can deal with the program’s many twists and turns.  If adding storage - specifically the Enphase AC Battery - to your present or planned PV system sounds like a good idea, give us call, we’re ready to bring our expertise to bear to help you get this right!

Intersolar 2016 - Bests & Worsts of the Hottest Solar Event of the Year

Its been a week since we returned from the most epic solar event of the year - Intersolar North America in San Francisco. Now that we are caught up on the backlog of emails and calls we can take a moment to reflect on key highlights from the event. 

Top 2 New Innovative Products to Watch

  1. BeamReach SolarBeamreachWhere do I start with this truly innovative new company?? Beamreach Solar unveiled a product called Sprint that includes the attachments, racking, and panel all in one. The panel frame and “racking” is entirely made of a composite plastic (material tested in automotive and other outdoor conditions for 20+ years). They demonstrated the installation of 6 panels in about 5 minutes! Designed for flat roof commercial projects, the tilt up back end pops out to click into a base which also pops out and sticks with a roofing adhesive to the roof. The front of the next panel then clicks into the base of the first panel and so on. The whole system is obviously much lighter (including a handle in the middle of the panel) and way faster to install than conventional ballasted systems. Best of all, no grounding required since there’s no metal to ground!
    While this is an awesome new product we have to wonder about a few things… 1) Do we have to powerwash the roof first for the adhesive to work? 2) What if a footing is incorrectly placed?! According to the great sales rep we spoke with… while the panels can be removed and replaced easily for maintenance, the footing is solid once it adheres to the roof so you’d have to essentially re-roof if you want to get rid of them. And 3) most roofs are nowhere near as flat as the surface Beamreach demonstrated on. How does the system deal with irregularities on the roof given the sticky feet are basically a flat square? We look forward to following this company as they work out the kinks in their exciting product. Keep your eyes peeled for a blog post where we dig in a little deeper on this.

  2. Photon - While we didn’t get to actually talk to the masterminds behind this new start-up the idea is spot on. Photon is a subscription based app whereby your smartphone (with the addition of a cheap lens from Amazon) can take a shade analysis on a roof. I don’t think many installers would shed a single tear giving up their SunEye or Pathfinders. We may just have to try this innovative new app out. 

Top 3 Developments from Existing Partners

  1. Energy Toolbase - These guys are the kings of data. We have been working with them since last year’s Intersolar to help us show our clients how solar will offset their electric bills with the greatest confidence possible. They are constantly adding more of the dozens of complex rate models around the country to their system. And now they’ve built in net metering 2.0 in anticipation of this huge change to California rates coming next year as well as storage into their models. Staying ahead of all the rate changes nation-wide is a huge undertaking but these guys are on top of it! 


  2. Life’s Good (LG) - While LG didn’t have a booth this year, Run on Sun’s CEO Jim Jenal enjoyed a breakfast where LG showed off their mammoth 375 watt, 72 cell panel. This is no surprise as LG continues to churn out higher wattage panels every year with their successful R&D department. Currently 320 watt, 60 cell panels (standard for residential solar) are available to us but it sounds like we can expect even higher efficiency coming within the year.  

  3. Enphase Energy - Storage beta installations are taking place in Australia where they recently mounted 4 units in just 45 minutes! Can’t wait to get our hands on them as many of our clients have expressed interest in storage. Looks like we may be able to get beta Enphase batteries in the coming year! Interested clients (especially those in SCE territory) please let us know if you want to be one of the first!

Top 2 Companies Trying too HardSmartFlower POP

  1. Smartflower POP - There was a lot of hubbub around this giant solar flower thingy. While I like that it has integrated storage and the dual axis tracker is great for increasing output in a big way…we couldn’t help but feel like this was way over engineered. There are actually several other solar flowers out there and I think solar-integrated art is a fantastic way to showcase to the public and get the social benefit when a solar system may be hidden on a rooftop. But take a look at this Smartflower. There’s some serious mechanics going on to make the thing open in the morning, track the sun, then close at night. Why it needs to open and close is beyond me and just seems overly complicated, heavy, and probably costly. (To be fair, we didn’t get the full spiel from the sales guys.)

  2. Ten K Solar - Sometimes its a fine line between being innovative and being overly complicated. When you decide to roll three “innovative” products into one maybe that’s a sign that you’ve crossed the line. I’m not sure if I’m more excited about the concept of wiring in series and parallel - making each “half” cell operate independently, or more confused as to why they orient the system north/south and eliminated MC4’s. To be sure there are some exciting things about this product and the people at Ten K definitely have thought outside the box. Will be keeping an eye on them for sure.

Top 4 Most Amazing Moments

Battle of the Bands

Kendra Hubbard, Jim Jenal, Jeff Spies, and me at BotB

  1. BayWa r.e. Customer Appreciation - As many of you know, Baywa r.e. is our fabulous distributor for many reasons. Namely they share a similar ethos and dedication to quality solar and an accountable honest industry that we do. But beyond sharing similar missions they also treat us really well!
    This year BayWa hosted a customer appreciation “chill out” area throughout Intersolar. Anytime the crowds and meetings were too much we could go sit outside in the shade, get a chair massage, and enjoy a cold beverage or lunch! Yeah, you heard me…Chair Massage. Best distribution partners EVER!

  2. Solar Summerfest - It wouldn’t be Intersolar without an epic party or two! This year’s Solar Summerfest did not disappoint. From the variety of food spreads (loved the veg options!) and bars (wine, margaritas AND whiskey?!) to the awesome entertainment provided by professional break dancers… this was such a fun time to relax and get to know our solar friends and partners. As the night went on the real highlights were seeing BayWa’s Scott Snyder rock the karaoke stage and CalSEIA’s Bernadette del Chiaro cut a serious rug on the dance floor. And according to Jim’s pedometer Jim and I danced an impressive 7216 steps with our friends at Everest Solar

  3. DeloreanBattle of the Bands - And then there was the Battle of the Bands where solar companies show off their employees’ musical talents (and the Solar Tribe hangs out, like the four of us in the picture above). Solar folks really know how to party!  Special thanks to Jeff Spies for hooking us up with invite only tix!

  4. Delorean! - Did I forget to mention the Back to the Future Delorean was on display…and I got to sit in it? That was a pretty cool moment for an 80’s kid like myself. 


Top 2 Most Annoying Moments

  1. When that guy I met at SolarFred’s Solar Tweetup (which was a great event by the way) asked me how Run on Sun was different than SunRun and couldn’t wrap his head around how installation companies can be so different. Even when given the most perfect metaphor… “We are like a microbrewery making delicious quality beer for the benefit of the people in the most sustainable thought-driven way, and SunRun is like Coors. NOT THE SAME.” He still didn’t get it, sigh. 

  2. TalesunWhen I casually walked the exhibition floor looking for current and future partners working for the betterment of the solar industry and the world at large…and was confronted with a booth filled with girls dressed in what looked like playboy bunny costumes. Jim already described his take on Talesun’s display choices and their obvious lack of understanding for why they received such a negative reaction in another blog. But as a woman working in this industry with a rare position including answering phones, designing layouts, pulling permits, AND torquing bolts on the roof… I felt personally offended by Talesun’s decision to use misogynistic objectification to try to sell their product. Due to my many roles I feel I represent, or have an understanding of, a lot of different people in this industry.
    And I’m not alone, according to the 2015 Solar Foundation National Census women represented 24% of solar jobs, surely even more today! When a quarter of your clientèle are women why in the world would you use booth babes to market your products? Solar is supposed to be different than other male dominated construction industries.
    This is supposed to be an industry that makes the world a better place and values everyone equally for their contributions. That booth did not speak to me positively on any level in any of my roles as installer, administrator, customer service representative, saleslady, health and safety officer, or general solar ninja. On the bright side I was pleased to hear that the majority of Intersolar participants made it very widely known how unacceptable Talesun’s display was. This only solidifies my feeling that this is a great industry for women, despite a few bad apples who may never “get it".

Top 5 Reasons Solar Soared in 2015!

There can be no doubt, 2015 was an amazing year for solar.  As we reach the end of the year, here’s our look back on the top five reasons solar soared in 2015!

5. Run on Sun had its Best Year Ever!

Run on Sun Top 500 Solar Contractors

While not the most important reason for solar overall, we would be remiss if we didn’t acknowledge that thanks to our wonderful clients, 2015 was our best year by far!  From our largest project ever for our favorite water company, to adding another school to our portfolio, to the many residential projects that we built all across Southern California, 2015 was a great year.

We took great pride in being recognized, for the third year in a row, as being one of the top Solar Contractors in the country by the wonderful folks at Solar Power World, and even more pride in the scores of referrals that we received from our ecstatic clients.

We can’t wait to meet and exceed our success this past year in the New Year ahead!

4. Politicians that Got It!

Political leadership on dealing with Climate Change was finally in evidence this year, and the resultant policies are, inevitably, pro-solar.  Exhibit A was California Governor Jerry Brown pledging to have the state generate 50% of its electricity from renewable sources by 2030, a mere fifteen years away!  Said the Governor:

I envision a wide range of initiatives: more distributed power, expanded rooftop solar, micro-grids, an energy imbalance market, battery storage, the full integration of information technology and electrical distribution and millions of electric and low-carbon vehicles.

We are on board with that!

But  political leadership extended far beyond the borders of our great state in 2015!  More than 190 countries came together in Paris to agree to the most far-reaching accord ever to address Climate Change, and lots more solar was high on their list of ways to achieve a more sustainable planet.

To be sure, none of these actions were without their political opponents, but it is impossible to deny that 2015 marked a major turning point in the public’s perception of the need to act, and those views were increasingly adopted by the world’s politicians.

3. Smart Energy Storage (Finally) Comes of Age (Almost)!

Ok, we have to give the man his due — Elon Musk’s outlandish PowerWall announcement changed the conversation around smart energy storage (and our blog post debunking his most outrageous claims became our most viewed post of the year!).  Indeed, storage went from being a topic hardly ever mentioned by a potential client, to something that nearly everyone did after Elon did his thing.

Unfortunately, the hype still leads the market, and mature products are still not really available.  But that is changing rapidly, and from our perspective that can’t happen soon enough.

2. Net Metering 2.0 Saves Solar in California — We Hope!

There had been great angst in the solar community about the future of net metering — the means by which solar owners get compensated for excess energy that they put out onto the grid — in California (and elsewhere).  Decisions about net metering in other states that bent over backwards to appease utility demands only ratcheted up the anxiety in California as the state’s Public Utilities Commission deliberated over competing proposals for Net Metering 2.0 - including utility schemes that could have gutted the market for solar.

Fortunately our fears were not realized and the preliminary decision — due to be made final in January — was quite solar friendly.  Once we have a final decision we will report on it in depth, but for now this looks like one of the biggest pro-solar developments of 2015.

1. Federal Solar Investment Tax Credit is Extended!

Losing money if the ITC goes away!The number one, most amazing, and most amazingly unexpected development to boost solar in 2015 is unquestionably the major extension of the 30% federal solar investment tax credit (ITC).

Given that the ITC was previously scheduled to expire at the end of 2016, solar installers, potential clients, utilities, and building departments alike were all bracing for what could have been a hellish second half of next year as all involved scrambled to get systems commissioned before the deadline.

Instead, the full 30% will continue through 2019, 26% in 2020, 22% in 2021, and 10% thereafter.  Moreover, the “placed in service” language — which required a project to be commissioned before the credit could be claimed, thereby leaving installers and clients at the not-so-tender mercies of the local utility — was replaced by the far more manageable, “commenced construction” requirement.

The net benefit of this will be a more orderly market, driven by rational purchasing decisions rather than a panicked stampede to meet an arbitrary deadline at the end of next year.  And beyond that, keeping the ITC in place for many years to come will help to grow solar in ways that would not have been possible otherwise.  The industry, the economy, and the environment were all winners here.

So that’s our wrap on 2015 — truly a great year for solar!  But we are betting that 2016 — with your help, of course — will be even better!  Watch this space!

Happy New Year!

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!
