Solar Spotlight: It’s no myth — microinverters work on commercial solar projects

We are excited to have participated in the recent episode of Solar Power World’s Solar Spotlight podcast, which explores the trend of microinverters in commercial and industrial solar installations. As microinverters continue to increase in capacity and can handle higher capacity PV modules, they are no longer limited to smaller residential solar projects. APsystems is at the forefront of this trend, with our new QT2 microinverter designed for use with four solar panels simultaneously, compared to conventional models designed for only one panel. During the podcast, Jason Higginson, head of marketing for APsystems USA, discusses this new breakthrough in microinverter technology and the potential benefits that they bring to the commercial and industrial solar market.

APsystems Busts Myths about Commercial Microinverters on The Pitch

Microinverters have long been a go-to in residential solar arrays for how they simplify installation, provide panel-level monitoring and shade mitigation, and meet rapid-shutdown code requirements. But can they have the same impact in the commercial sector? APsystems’ Senior Director of Marketing USA, Jason Higginson, sat down with Solar Builder magazine on The Pitch to answer that question. Discussing APsystems’ quad microinverter, the QT2, he busted common myths about microinverters in commercial arrays, including their cost, power output, and points of failure. (Spoiler alert: the QT2 comes out on top!)

303 Battery: When the global benchmark for sustainability is a Net Zero

APsystems Project Award Commercial Winner – Sustainable Living Innovations with Adkisson Electric

The Belltown district in downtown Seattle is the city’s most densely populated neighborhood. Known for its vibrant nightlife, it boasts some of the area’s best restaurants, galleries, and music venues. It now also has the distinct privilege of being home to the world’s first high rise apartment building given the highly coveted Net Zero designation by ILFI (International Living Future Institute). 

Designed and built by Sustainable Living Innovations, the fifteen story building is unironically located on Battery Street and represents the pinnacle of sustainable architecture and design. Sustainable Living Innovations uses its patented building technology, which incorporates all necessary mechanical, electrical, and plumbing infrastructure into wall panels that are fabricated off-site to specification. Once the wall panels are completed, they are delivered to the project site and placed, much like legos, on the building’s steel frame. This process has huge benefits including an accelerated time to market, as delays due to PNW weather are no longer a factor, as well as much less material and labor force waste when compared to traditional construction methods. 

The largest contributor to the energy savings is the use of 622 solar panels, expertly installed by Adkisson Electric, which adorn a large section of the building’s facade as well as the rooftop terrace and balconies. Using over 300 YC600 microinverters from APsystems and in conjunction with a combination of PV panels from QCell and Lumos, the on-site solar array generates roughly 210k kilowatt hours annually. The microinverters also come equipped with power factor control capability which allows for power factor adjustment according to utility, transformer, or battery requirements from the building’s energy storage system.

Making up the difference are several other energy saving systems that include a DC low voltage lighting system and a waste heat recovery system from SHARC that pulls heat from hot gray water and converts it back into energy that is then stored for future use.

The 303 Battery building is truly one of a kind but with Sustainable Living Innovations lighting the way, we can be sure it won’t stay that way for long. 

APsystems is very proud to award the APsystems Commercial Project of the Year for 2023 to Sustainable Living Innovations with Adkisson Electric for their revolutionary 303 Battery project!

Quixote Village: A community vision for sheltering the homeless

APsystems Project Award Non-Profit Winner – Quixote Communities in partnership with South Sound Solar and Olympia Community Solar

When Quixote Village first opened its doors in 2013 to some of Olympia, Washington’s most vulnerable citizens, it was not only the culmination of years of hard work from countless individuals but the realization of a community vision; to provide a safe space and permanent housing to Olympia’s homeless population. Originally established in 2007 as a nomadic encampment called Camp Quixote, the camp’s members would take refuge in the parking lots of local area churches for up to 90 days before having to uproot and find another church willing to offer their parking lot for the camp’s uses. The camp existed like this for nearly seven years, ever moving from parking lot to parking lot, before interested community members took things into their own hands, started a non-profit, and petitioned Thurston County to provide permanent space for the camp. The county answered and granted the property where Quixote Village now stands.

The village consists of 30 individual tiny houses, roughly 140 square feet in size which includes space for a bed, modest storage space for belongings and small furniture items as well as a toilet. Showers and kitchen facilities are housed in the on-site community building. There is also a media room and a community garden where the residents find a great deal of joy and pride.

From inception, there was always the hope of incorporating solar energy into the infrastructure of the village but it always seemed just out of grasp. That is, until Olympia Community Solar, another community non-profit, reached out to the Village earlier last year and offered to spearhead the initiative and take on the often complicated and tedious task of securing funding through a number of different grant channels. South Sound Solar was also an instrumental partner, not only in the installation but of the design of the solar system, as well as coordinating with the necessary utility companies.

The roof of each of the tiny house units now boasts four solar panels, each tiny house solar array producing roughly 1KW. Coupled with APsystems YC600 microinverters which are critical to the system’s specific architecture, and supplemented by panels on the roof of the community building, the solar system saves the village nearly $8,000 per year, money that is reinvested back into the village in the form of on-site mental health support, facility maintenance, better food, and other enrichment programs designed to foster and support the health and safety of the residents.

Happily, Quixote’s vision doesn’t end here. They’ve already opened a second community for homeless veterans in Pierce County in May of 2021 and have broken ground on a third village in Shelton, WA. Both of these new communities have planned solar as part of their energy infrastructure.

APsystems is incredibly proud to award APsystems Non-Profit Project of the Year for 2023 to Quixote Communities in partnership with South Sound Solar and Olympic Community Solar for their inspiring efforts at Quixote Village!

Uninstalling and Reinstalling: Optimizing A Residential Solar Array in Indiana

APsystems Project Award Residential Winner – Apollo Solar

The owners of a house nestled in an Indiana suburb were dealing with a variety of issues. Firstly, due to a poorly installed chimney flashing, the roof sustained water damage and needed replacing. That meant that their current 45-panel solar array had to be completely removed. However, this obstacle quickly turned into an opportunity for Apollo Solar to install a much more efficient solar energy system for the homeowners. 

Due to regulations the neighborhood’s homeowner association had at the time of the first install in 2016, the panels were currently positioned on the shadier back side of the house. On top of that, the previous installer did not have the best practices, leaving the homeowners with loose cables, extended rails, odd panel layouts, and conduit resting on gutters. Now, in 2022, no homeowner association regulations were stopping Apollo Solar from placing the panels on the much sunnier front side—-and doing the job right this time.

With this house being located in shady suburbia, installing inverters at each panel to maximize output just made sense. By using APsystems microinverters, Apollo Solar was not only able to optimize their client’s solar panels but give them the power to monitor each panel individually and, ultimately, give them confidence in their solar system that they didn’t have before. 

Congratulations to Apollo Solar and their “45-Panel Uninstall-Reinstall” project for being awarded APsystems Residential Solar Project of the Year for 2022!
