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.
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!

It is official! One million solar systems have been installed across the United States providing more than 27 gigagwatts (GW) of clean energy over the past 40 years! This incredible milestone becomes even more impressive when you consider that projections have us reaching 2 million installations in just 2 years.
Every day at Run on Sun we are proud to be part of the solar movement helping our communities access clean renewable energy. Solar is no longer a fringe technology, nor is it a solution for the future. It is powering homes and businesses nationwide today, and the more solar we install, the more jobs and economic growth we support.
On Tuesday, May 3rd at 10AM EDT solar supporters across the nation are participating in a social media “thunderclap". Join us in celebrating and sharing this historic achievement and what it means for our energy future by spreading the word across your networks. Working together to raise our voice in unity shows our business leaders and lawmakers that solar is here to stay. We are #MillionSolarStrong! Join the SEIA organized movement and thunderclap here.
Longtime readers of this blog will know that we have been following the progress of the Solar Impulse team for many years. Headed by adventurers/pilots Bertrand Piccard and André Borschberg, the Solar Impulse project was about building an airplane that could fly around the world powered only by solar power!
The original craft, Solar Impulse 1, flew across the United States back in 2013 as a proof-of-concept design that could set the stage for the around-the-world attempt. That audacious enterprise begin in March of 2015 as Solar Impulse 2 launched from Abu Dhabi on its way around the world. Last summer, SI2 made it to Hawaii, but the effort needed for that extended non-stop flight from Japan damaged the batteries and required some redesign and retrofitting before the mission could proceed. But this Thursday, April 21, was finally the day, and SI2 departed from Hawaii, headed for a landing at Moffet Airfield outside of San Francisco - a 62 hour flight!
For those who haven’t been following the mission, since there is only one pilot on-board, he can never really sleep during the flight. Instead he takes power naps of 20 minutes at a time, assisted by self-hypnosis to quickly bring about a state of relaxation. In addition, the pilot does yoga and the limited exercises afforded by his incredibly small and cramped cabin.
But how does the plane itself - which is only powered by sunlight - manage to fly at night? By an ingenious combination of electric and potential energy storage. During the day, SI2 follows a flight profile of climbing from 5,000 to approximately 28,000 feet. Sunlight charges the batteries through a collection of more than 17,000 monocrystalline silicon solar cells. Then at night, SI2 begins a gentle descent, mostly gliding from its lofty height, to begin the process all over again.
So how did it turn out? As these great images make clear, pilot Bertrand Piccard, made it safe and sound. The revised systems performed with out a hitch, and SI2 cruised past the Golden Gate Bridge on its way to a successful landing.
Ah to have been in the San Francisco Bay area yesterday! What a beautiful and inspiring sight!
The Solar Impulse team still has a great deal of work ahead of them including crossing the United States (they will be flying into New York City which should be something!) before crossing the Atlantic as they complete their mission of showing the world the true capability of clean energy.
Three weeks ago the Run on Sun team took San Francisco by storm for the annual Intersolar events and exhibition. In the solar industry products are changing incredibly fast. Intersolar and Solar Power International (September 14-17th) are the two most important events for industry experts to come together and be able to put our hands on the latest and greatest products while establishing relationships with potential partners around the world.
As we mentioned in our Intersolar 2015 Preview blog, we were really on the prowl in the exhibition hall. Number one on our list was to find viable storage options as our client-base is quickly shifting to time-of-use rates and smart storage will be a huge asset to enable more local consumption of energy at the right time, as well as to reduce those high demand spikes for commercial clients.
Enphase Energy, of microinverter fame, actually had their own booth at IS this year, a first for them, and their emphasis was on their modular storage solution - which they call the AC Battery - made possible by their next generation, S-Series microinverter - which is bi-directional. Since the system sits on the AC side of a solar installation, it is compatible with any solar system whether it uses Enphase microinverters or not.
Enphase readily acknowledges that the economic proposition for local consumption is not really present in the U.S. yet, which is why they are first rolling the product out in Australia. However, as the present discussions before the CPUC demonstrate, net metering is changing and soon. When it does, the economic case for systems like the AC Battery will become compelling.
Second task on our list was to find out what panels LG would be offering and when we could start getting them on rooftops. Since LG didn’t have a booth at IS, hints toward panels with higher efficiency and higher output were verified by a meeting with our distributor, Baywa r.e. (formerly known as Focused Energy).We are now looking at 310 and 315 Watt panels available in September. This is up from the 305’s currently available and 260’s which were available this time just one year ago!
Our last mission as we weaved through the multitude of flashy products on display was to find better options for racking. While we have no intention of finding an alternative for our pitched roof racking company, Everest, our ballasted flat roof racking experience has left something to be desired by our installers. And the growing interest in solar carport systems means we need a good partner we can rely on to develop beautiful high-quality structures. We looked at several new products and talked to some great people on this front. We will be vetting these companies and discussing the applicability of their options with our clients over the next few months.
Any good industry gathering has GREAT parties, and the solar community definitely delivers in this department. The Run on Sun team enjoyed rubbing elbows with solar celebrities, new and old friends at various social events throughout the week. Laurel ate breakfast and discussed gender-specific solar challenges with WISE (Women in Solar Energy). The lunch hour Tweetup hosted by @SolarFred and put on by our friends at @Enphase, @RECSolar and @Grid was a blast. Of course the Solar Summerfest put on by CALSEIA and the Solar Battle of the Bands were not to be missed either. Who knew solar companies had such amazing musical talent?! The battle of the bands was more packed than we’ve ever seen, the only painful side to an ever expanding industry. Laurel’s favorite, the awesome funk band from Sungevity rocked the house and took home the winning title. If you attended either event you probably spotted Run on Sun’s Jim, Laurel and Josh making full use of the dance floor! No one on the RoS team will deny…we DO like to have fun.

Thanks Kendra Hubbard for the pics!
Its hard to believe that in just over a month we will be boarding a local train to Anaheim for Solar Power International, “North America’s largest solar trade show". Beyond what we saw at Intersolar, our distributor Baywa r.e will have a presence as well as our favorite solar panel manufacturer: Life’s Good Electronics. We’re looking forward to more exciting product announcements and connecting with friends once again! Hope to see you there!
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).
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!)
We 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.
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!
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.
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.
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!
