We installed a 9.28 kW system for Prairie Unitarian Universalist Society. With 16 Philadelphia Solar modules and a GoodWe inverter, it’s estimated to offset over 90% of their electric use!
We also helped Prairie UU Society secure a Focus on Energy reward, Solar-for-Good module donation, and a Madisun Backyard Solar Grant. ☀️
