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.
