Your Solar Builder editor entered the whirlwind of news, numbers and handshaking that is Solar Power International and emerged with a notepad filled with gibberish. What language is this? What secrets does it hold? We sent it to a forensics lab, the archaeological department at Oxford and the guy with wild hair on Ancient Aliens for their interpretations. After this thorough analysis, we believe these are the top solar story lines in a post-SPI world …

1. Focus shifts from federal politics to local action

You get the sense that the solar industry has finally punted on trying to waste much more time inching the message boulder up the current administration’s hill and is now putting those resources into local efforts. This is likely the better route to go anyway, and the initiatives announced at SPI could do the trick if developed.

Just before SPI kicked off, the Solar Energy Industries Association (SEIA) and The Solar Foundation unveiled the Solar Automated Permit Processing (SolarAPP) initiative, which is the latest collective effort of the industry to streamline permitting. Reforms include: A safety and skills training and certification program that allows residential and small commercial solar and battery storage installers to attest that their projects are compliant with applicable codes, to eliminate traditional multi-step permitting processes; a standardized online platform provided to local governments at no cost, a list of established equipment standards and/or certified equipment for solar and storage projects installed through the proposed process and more.

There have been several attempts at this over the years, all of which fell short, but this one might have a shot because of the timing. The economic case for solar has never been better, and the technology and techniques are proven with copious examples to highlight.

Also, what local government would turn down the promise of a ton more jobs? To grow that base of skilled solar workers around the country, the Solar Training Network introduced AmericanSolarWorkforce.org, an online platform to help solar companies recruit qualified candidates; allow solar job seekers to find career and training opportunities; and help the entire industry build a strong and diverse solar workforce. Using this platform, which is free of charge, employers can post opportunities on a solar job board and connect with thousands of candidates looking for solar career opportunities. Employers can also create company profiles, review candidate applications, and communicate with potential hires.

2. Solar pros see the short-comings of the industry and are actively trying to address them.

Two key examples here. First is in grid services. Features for grid services are mentioned all of the time now, from inverter and optimizer products to the need for storage and other ancillary services. I take it as a sign that the relationship between utilities and solar companies is now evolving past an adversarial stage because there’s nothing left to prove about solar as viable generating asset. Now, solar has to prove how it will best integrate and play nice on a wide scale over the long-term. This was always the case, but it feels everyone is getting on the same page about pursuing solutions.

For example, of all the things bouncing around the mind of CJ Colavito, VP of Engineering at Standard Solar, these days, he most wants to find a way to sync third-party radar forecasts with smart inverters for advanced ramp rate control — to ramp down voltage slowly prior to cloud cover that will cause voltage flicker.

SEIA CEO Abigail Ross Hopper and SEPA CEO Julia Hamm discuss diversity as an important goal for their respective industries.

The second short-coming is a short-coming for most industries: diversity. Judging by comments during the opening session and the upcoming Solar Jobs Census, solar thought leaders realize the industry is in position to not just remake the grid, but the makeup of the American workforce – not just to be PC and nice but because there is value inherent in a diversified workforce with growth opportunities. Also, check out this initiative from SEIA to work with Historically Black Colleges.

3. The full solar life cycle needs more attention.

One area in the U.S. solar industry still in need of attention is the full sustainability of a solar project. For example, panel recycling is a fairly big can that keeps getting kicked down the road. A DNV GL report released at SPI listed stranded assets as a key question in its market mechanics. At some point we will run out of road and kick that can straight into a million tons of PV that needs to be put somewhere. This isn’t a crisis (at least not yet) because there are solutions, at least according to First Solar, which has developed a standard for doing so and been put its system in place. Solar is recycled fairly easily — and for a profit — in Europe and that model could be replicated here.

The next can soon to be kicked is in storage. Storage is basically the key to solar taking over the world, but storage is dirtier than solar on the clean energy scale. Cobalt is a safety hazard. Lithium needs to be mined and poses its own potential for fire. Lead-acid battery companies claim to have the most recyclable solution, but does it perform as well as the future needs? And also, it is comprised of lead and acid. This is stuff that needs to be fully considered within the grand plans.

4. So many storage solutions…

LG energy storage

The new LG energy storage system.

Speaking of storage, every turn on the trade show floor seemed to present a new energy storage system or bundle of products to solve all sorts of solar + storage equations, from simpler backup capabilities to time of use to peak shaving and on and on. Panasonic has a full solution pairing Pika’s islanding inverter with its batteries and modules. LG debuted its complete solar + storage system for the home. SimpliPhi has varied its case sizes and voltage range. Sonnen has gone full tilt into energy management + home automation – a long fantasized idea that is now real-life – that is more load shaping than load shifting.

It’s all very cool. The issue from installers we chatted with at the show is there’s no one software that can deftly handle all of the storage mathematics they need (those that are great for peak shaving can’t be used for resiliency, etc.). There’s more to figure out here, just like on the battery side, but each SPI feels closer and closer to the goal line.

5. Some cool C&I rooftop innovations.

The reigning champion for the “biggest solar opportunity with the biggest issues to solve,” the commercial and industrial rooftop, saw several big-time debuts to ease some of these headaches.

A ton of solar deals are off the table because of the commercial rooftop life cycle and price tag. The deals that do go through on a different timeline than the roof itself are going to be a huge headaches come roof replacement time. Headaches meaning stuff will for sure be broken when the solar system is removed, stored and put back on. Standard Solar and Carlisle Roofing teaming up to solve this at the outset with a bundled package — a new C&I silicone coating spray applied to the existing roof membrane (with optional insulating foam) that installed with the PV system. The deal is financed through a PPA agreement with Standard Solar, so the building owner is essentially paying for the new roof (good for 50+ years) during the 25-year PPA.

ESDEC rooftop solar mounting system

The ESDEC Flat-Fix

On the system side, available in the first time in the U.S., Holland-based ESDEC debuted its slick Flat-Fix commercial rooftop mounting system. The same lightweight design can be laid out in south-facing or east-west configurations and is built with one tool, keeping the SKUs at a minimum. The feet are adhered with glue (or a bolt if needed) and an optional ballast tray. The system is already proven but the team needed to make a few tweaks to launch in the U.S., mostly relating to cable management, all of which were cleverly designed like the rest of the system.

Remote C&I system design has never been easier thanks to Nearmap’s updates. Its digital surface and line of sight analysis produces a jaw-droppingly clear picture for 71 percent of the U.S. population that is updated 3 times per year. You can really tell the difference between obstruction or dirt, as well as accurately measure the pitch and dimensions of any surface. When combined with the newest version Aurora Solar’s software, Aurora estimates 10x performance upgrades for multi-megawatt, commercial-scale solar projects added with the ability to simulate the solar energy production of a PV system while designing, allowing real-time assessment of design choices and elimination of change orders. An enhanced “fill zone” functionality is also available to automatically optimize solar panel locations to maximize the number that fit within an available space.

6. The next big trend will emerge from the California solar mandate (and maybe it’s an old one?).

Consider a company like CertainTeed – been around for a long time, and didn’t have a lot new at its booth to discuss. Its solar products are focused mostly on roof-integrated options that are not as popular as traditional mounting + solar panels on an existing roof sold and installed by solar installers. But when all new homes in California are going to need to come with solar already on the roof, will builders and roofers favor something like this they can handle themselves? Or, consider SunFlare, a company with a flexible CIGs technology. In 2018 it seems like a niche product – can be installed on top of existing carports and other nontraditional areas, but it’s close to working with a high-end national homebuilder that liked its solar shingle because “it’s a roofing product, not a solar product,” thus allowing them to install new solar on a new house without contracting out. The president of ESDEC also mentioned that in Holland their mounting system is seen as so simple to install that HVAC companies are a big customer segment for them because they could easily add it to their service offering.

Will the mainstreaming of solar earlier in the building process end up cutting out companies and products that rule the day today? Maybe a wild thought, just remember to keep your hands and arms inside the solarcoaster at all times.

Panasonic HIT panels.

Solaris Technology Industry, Inc., a national solar distributor, has now added LG Solar and Panasonic solar panels available for purchase through their website. The new solar panels are available to both consumers and installers for residential and commercial system applications.

“Looking forward, we anticipate a demand for even higher quality solar panels. These are the best PV modules available on the market, and we are able to supply them to DIY and installers alike for much less than traditional retail outlets,” said Brandi Casey, of Solaris-shop.com. “Interest in our systems are grown tremendously over the last year, and we anticipate further growth to continue with the new additions of these manufacturers. We also see solar paving the way forward regardless of the tariffs.”

Solaris delivers solar energy products for wholesale prices to consumers and companies nationwide.

Hoosier Efficiency: Walk through the solar decision-making process with this Indiana homeowner

solar in bloomington

Bloomington, Ind., isn’t a typical solar energy hub, but homeowner Karim Abdelkader and Alex Jarvis, president of Solar Systems of Indiana, prove that it can be with the right customer and PV solution.

The goal for the Abdelkader family was to put panels on both their home and adjacent pool house, spanning over 4,000 sq ft to produce enough energy for both structures and the pool itself, offsetting their total energy usage by 80 percent. Abdelkader also wanted to be assured the panels would withstand the typical weather conditions in central Indiana (humid summers, snowy winters). What’s more, he wanted to install panels that would blend well with his home’s appearance.

PV solution: LG NeON R

For a savvy customer like this, the only option is a high-efficiency PV module that is reliable, durable and comes with a robust warranty. This led Jarvis and Abdelkader to install 58 LG NeON R panels to maximize the power output and cost-effectiveness.

“We started using LG about three years ago; they’re a great balance between efficiency and value,” Jarvis said. “I really like that LG is a globally diversified company. It’s a very stable and secure company that lends itself to an installer to put up equipment that we know will have support and project backing moving into the future.”

For starters, the LG NeON R produces 365 kW per hour (typical panels are about 350 kW per hour), which hit Abdelkader’s goal of offsetting energy by 80 percent despite the limited roof space available in this project.

Addressing Abdelkader’s concerns about durability and reliability, Jarvis explained the LG NeON R came with a 25-year labor and materials warranty that covered the panel if there were any issues. The warranty further ensured long-term stable operation, with a guarantee of at least 87.0 yield relative to initial performance after 25 years. The panels are also low maintenance, only requiring occasional routine cleaning.

“That was a key driver behind our decision — what does the warranty look like?” Abdelkader said.

The NeON R also has a black backing to better blend in with the roof line of the existing structures, maintaining the
aesthetic appeal of the home.

Project results

Construction was completed in October 2017 with the system expecting to yield an estimated 26,250 kWh/year. The installation was completed mid-month, but Abdelkader had already seen his full month energy bill cut in half. Bloomington’s net metering arrangement also allows Abdelkader to receive financial credit for the excess energy gained through the LG NeON R.

“The first month, Karim sent me a text and was very excited about how low his energy bill was,” Jarvis said. “Even without a full month of being energized the system has offset quite a bit, so solar has met his expectations and then some.”

Creative installations: Three solar project designs with aesthetics in mind

With the right customer, a new PV system can be more than just a way to reduce an electric bill and even become an aesthetic calling card. As we prep our Project of the Year issue, we thought we’d share a few of these concepts.

New Hope Community Church

Palomar Solar PV design

Installed in Chula Vista, Calif., this is believed to be the first design of its kind. Palomar Solar came up with the idea to use black on white panels for the design of the cross and black on black panels to frame it. The church was very excited and did not reveal what we were up to too the rest of the congregation including the Pastor until the install was completed. Palomar used LG modules, SolarEdge inverters and Everest mounting systems to complete the job.

Guido & Companies

Freedom Solar Power

Freedom Solar Power recently designed and installed a one-of-a-kind project for Guido & Companies Inc. that uses solar panels to spell out the word “GUIDO” on the building’s rooftop and doubles as creative aerial advertising.

Guido Construction Company and Guido Building Materials Company are located right next to the San Antonio International Airport, so people flying into or out of the airport get a prime view of the company’s large solar panel “billboard.”

The 85-kW project is comprised of 260 SunPower modules, will meet than 60 percent of Guido’s energy needs, and will pay for itself in less than 4.6 years.

There were significant space issues that made installation very technical, according to Freedom Solar’s lead designer Josh Meade. The roof’s tilt changes on the left and right sides of the building, which required two separate arrays on the main part of the rooftop project where the word “GUIDO” appears. Freedom Solar also had to install a third array on the other side of the building to increase the number of panels and reach the desired kilowatt-energy production.

 

The project features 327-watt high-efficiency solar panels SunPower, which are the most efficient available today and unmatched in reliability with an expected useful life of more than 40 years. Freedom Solar is a SunPower Master Dealer, the only company with that distinction in Texas.

The Solar Labyrinth

solar labyrinth project

solar labyrinth PV

Solar Labyrinth was commissioned by Dr. Allan Berger of Bright Eyes and Bushy Tails Veterinary Hospital in Iowa City, Iowa, and designed and fabricated by Anthony Castronovo. The project was an outgrowth of a 40-kW solar installation on the roof of the building. The goal of the project was to design a creative solar sculpture that would add to the visual presence of solar power at the site while also creative an exciting work of public art. The ancient Greek myth of the Minotaur became a focus of discussion and the Labyrinth form was the resulting physical embodiment of this ancient story. Each of the 14 panels on the interior of the structure have a different animal surrounded by a sine wave pattern to reference the path of the sun. A Minotaur sculpture will eventually be added to the center of the labyrinth to complete the project.
