Solar Power for shop.
Posted: Sun Jul 22, 2012 11:49 am
Having a 30' x 40' pole building constructed for a shop and machinery storage. Commercial electricity is available on site, but costs $18- a month even if no electricty is used. Commercial electricity is not hooked up.
Building almost never used at night. Building will be wired for 120 volt lighting and outlets, powered by one of 3 generator sets on site. 10KW the largest generator set. Previously crunched the numbers and for no more than the buildings on the acreage are used at night, it's much cheaper to purchase gas for the generator sets. Also keeps the generator sets exercised for use during major power outages.
Thinking about purchasing a solar panel and controller to charge up 12 volt batteries. Using batteries to occasionaly provide some interior area lighting and motion detector perimeter lighting at night. A 50 watt solar panel with 8.5 amp charge controller cost around $250-. Estimate pay back time is 14 months when compared to just having commercial electricty available.
Looking for thoughts and input.
