solar power

Long shot, but anyone using any type of solar power? We are looking at utilizing some of our empty space around the building and a thought was installing solar panels.

It's common in areas where utility power is a PIA and the needs are modest. It really boils down to your needs as the array can be as big or small as you want/can afford so long as the inverter is the right size.

Couple things to keep in mind:

1) Will you generate more power than consumed. Then you need to research your state's grid connect deal for backfeeding (spinning the meter backwards). Some states require dual metering, others simple go off a net meter reading.

2) NEC code has been updated with very specific rules and requirements for photo-voltaic and wind installations and related net connections. Hire an electrician well familiar with the new code section. It's not as simple as you think. And the safety and disconnect rules are well founded. Don't ignore them or you will loose your commercial electric service.

3) Do you want battery storage for a UBS type arrangement on all or part of the load? Such would be used to run overnights and on rainy days where solar iridescence is low compared to even a cloudy day. Snow?

4) Will you be able to access it for snow removal and periodic cleaning. While snow would be an obvious thing to remove as soon as practical, dust/dirt will accumulate on the panels and cut down the performance significantly. As will rime ice.

5) Does your utility, state and local AHJ offer any rebates or other incentives to add renewable? Such as a property tax rate reduction...

6) How will it play with your generator? If you generate too much PV energy, you will damage the alternator. You need to always draw something from the genny.

6) Finally, work a part-cash/part-trade deal with the a local installer unless they're already busy.

Good luck and let us know how it turns out.
