Battery Backup System on Steroids

Solar PV panels installed on custom agricultural shed

Working closely with the homeowner, we built a custom agricultural shed using recycled building materials. The shed roof holds 11kW of solar panels.

Once generated, the DC power travels 550 feet underground to the home – where it charges the 48 volt, 811 amp hour battery bank and runs the electrical loads of the house. This system is built to keep its owner in power, from a short power outage to a total grid meltdown.

Interestingly, the owner decided to use high grade US made Deka Unigy II batteries, which have a practical use life of 15 years. Using the 30% tax credit on the first set of batteries helped to justify the higher cost.

Also worth noting is that the customer specified more expensive US made panels and inverters, stating, “I didn’t install the system to make money. I did it because it was the right thing to do.” His good intentions have been rewarded, though: the system has been a very good investment.

Commercial Flower Grower Solar


This commercial solar installation will provide 100% of the power used in the flower growing operation at Blue Heron Farm in Nelson County, VA. It’s on a smaller scale than some of our other commercial installations, but no less exciting!

Owners Bev and Keith work to protect the environment by using organic practices on the farm. They felt compelled to speak out against the proposed pipeline cutting through their region, and they wanted to make a concrete change in the way they procure energy. They would have installed the system even if the return on investment was not so good. They have also installed a system to generate the electricity used in their home.

“We’ve had a great experience with SunDaySolar.  The company did excellent work in maximizing the number of panels for our space, and demonstrated installation skill with our roof type.  SunDaySolar expertly guided us through the available incentives, and when one of our inverters needed a reset, they were out there the next day for us.  Kudos!  and thanks.”  – Jeff Kay

Commercial Ground Mount


This 36kW ground mounted system was the first of four systems we installed for Cedar Park Storage in Verona, Virginia. In total, CPS has over 75kW of installed photovoltaic (PV) solar. They also have a solar thermal system heating the water for the manager’s apartment and office warehouse complex.

The systems were installed using the REAP Grant, which provides 25% of the system cost back to the owner in cash. Return on invested capital for a system owner is above 25%. Business owners, we offer our grant writing service free of charge!

Please note, in all our systems, the panels are plum, level, ….perfect. We take pride in our craftsmanship.

Congress extends the 30% Tax Credit for solar for 5 years!

The 30 percent solar tax credit was set to expire next year and will now extend through 2019 before tapering to 10 percent in 2022. FYI, the wind credit had expired at the end of 2014, and the extension will be retroactively applied from the start of 2015 through 2019, declining in value each year. This means that the growth and momentum that the industry has claimed can continue for the foreseeable future. This is a very good thing for the future of renewable energy, the environment, and we will all benefit by cleaner air, water, and land.
