In a series covering the process of building an eco-friendly and energy-efficient home in Minnesota, Jessica Fishman describes the process behind installing solar.

In an earlier article, I covered all things energy consumption and efficiency, but in this article, the focus is on energy production. As soon as the utility connected the electricity at the end of January 2025, I started the process of going solar. As the house build proceeded, I searched for a local solar installer, evaluated PV system size, and considered including a battery for backup to keep the well and septic running in the event of a blackout – especially from storms.
In Minnesota, there are several programs incentivizing residential solar. Net Metering, which luckily was not overturned during the Minnesota 2025 spring legislature session, is compensated at $0.14251 per kWh. On top of NEM, Xcel offers a solar rewards program which is an additional $0.03 performance incentive per kWh (based on DC not AC) for systems 20 kW DC or less. An additional parameter of this program is that the PV system can not generate more than 120% of the consumer’s historical electricity use, or for new builds, there is a square footage calculation (see below). And despite some earlier rumors of the 30% ITC for residential solar (25D) ending the day of the OBBB passing, I will be able to take advantage of it through the end of this year.
After evaluating a number of quotes from installers and the incentive programs, I decided to proceed with a quote from Energy Concepts for a 32-panel 13.44 kWdc/11.4kW ac PV system with an EV charger and forward compatibility with a battery. This meant I would forego the solar rewards program, as I would have been limited to a 5.69 kW system size. Per the estimations, the PV system will produce 17 MWh annually in its first year, taking into account a 7% snow shading, 39-degree tilt, and 180-degree azimuth.
However, once I decided on the PV system in early February, there were still a significant amount of logistics, paperwork, and waiting until I could proceed with the installation. During which time it felt like at every turn, there was a bump in the road:


While the PV approval steps occurred, the interior and exterior of the house quickly progressed and completed. I was able to move in to the house in spring, and on move in day a severe storm occurred that caused a power outage – making me rethink my decision to delay battery backup. But, fortunately, power was quickly restored.
Shortly after move in, I began planting on the land and working on soil restoration. On Memorial Day weekend, I broadcast by hand a nitrogen-fixing diverse seed mix, nicknamed “everything but the kitchen sink” on about two acres of the land where I am planning on growing food. While on a different on-acre section, I planted a pollinator mix. On the land directly surrounding the house, I planted a no mow, low grow clover seed mix that also acts as a bee habitat. Plus, I planted a variety of trees, including multiple evergreens, crab apples, and edible fruit trees, such as apple, pear, cherry, and plum. While inside the home, I installed large planters for growing food year-round.

To validate the success of building a sustainable home, my builder, Justin Riddle of Paltrin, had a HERS (Home Energy Rating System) score calculated. HERS scoring was developed by the Residential Energy Services Network (RESNET) and is a nationally recognized system for inspecting and calculating a home’s energy performance. A HERS score of zero indicates a net zero home. Without solar, my home received a score of 25, which is considered a very strong score, and is tied for second place in the state for homes without solar.
And now with the solar officially interconnected the week before RE+, the HERS score is now -32 as it produces significantly more electricity onsite than it consumes. This scoring helped to confirm that I was able to build my dream home, even if it is “not your average dream home.”

R56 walls and R91 ceiling rating? Not using fiberglass or blown in insulation. I assume you have a heat exchanger for warming or cooling outside air since I assume the house is very air tight. Many items were used that the typical US person can’t afford when building a house in order to reach the -32 HERS score.
