What You Need to Know

Description:

System is 30 Canadian Solar mono silicon 250W panels fed through 6kW SMA grid tied inverter. Inverter was converted from a Windy Boy unit that I previously used with a 10kW wind generator on an 80' tower that I used for several years.

Maintenance Requirements:

None

Efficiency or Sustainability Improvements:

Insulaterd concrete form house extremely tight and very well insulated and quiet. 96% efficient propane Rinnai boiler is silent and provides plenty of comfortable radiant heat and unlimited domestic hot waer. Fujitsu 9kBtu mini-split heat pump provides second floor heat, A/C, and most important summer dehumidification (coastal home).

My Motivation:

Desire for minimal utility costs, energy efficiency, clean energy.

Advice:

Having used a wind generator, I found that it worked well, but required a lot of attention, resulted in some noise - especially when wind > 25mph, concerns when potential for wind >75mph. Some neighbors complained, some thought it wonderful, permitting can be hassle. Solar is pretty much install and forget, is now cheaper than wind due to cost reductions of panels, and in my case makes no sound, invisible from the street, and more dependable.

Experience with Installer:

Absolutely the best. 2-day install, site clean, minimal intrusion, professional. Would use them again and highly recommend them.
