You can’t be named Greener Days Farm without being environmentally conscientious. Since our property is a ½ mile from the road and utility lines we had the advantage of starting from scratch. We researched wind and solar power and ended up picking solar based on cost, reliability and efficiency.
Our 18 245 watt panels are rated to generate a maximum of 4.5 kilowatts but on beautiful winter days when the sun reflecting off the snow is blinding, the panels can push out 4.8 kW. After researching mounting kits we quickly realized it would be much more cost effective to build our own. Based on wind loads, we decided to build a strong A-frame that can withstand 100+mph winds – which can occur on the coast of ME. Laura and her mom stained the massive frame by climbing all over it like it was a giant jungle gym.
The power center, located in a room in barn#1, holds 36 batteries, the charge controller, inverter, breaker boxes, and lots and lots of wires. After lots of research, wiring diagrams, and consultations, Laura’s dad got the whole system up and running. The batteries store 900 amp hours that keeps our farm (with 4 freezers and two refrigerators) cranking along without interruption for 2-3 rainy days. To keep the lights on when the sun refuses to come out and the panels are covered with snow for days on end a propane fired generator stands at the ready.
