I have 660 watt worth of panels on my rv powering lights, TV, microwave and recharging electronic devices. I'm limited by roof space. Before adding the solar panels, I used my generator, now I only run it once a month for maintenance. It is not practical for my condo.
Your gas guzzling RV?
It would be pointless to go off grid since initial power has been paid to be hooked up. They would now only benefit the bill.Doubtful you could go off grid as your shop probably uses a lot of power. Most residents don't use very much. The biggest issues involve timing and storage or batteries. Growth of Solar power usage in rural areas far outpaces it's adoption in the cities. My brother has 10,000 watts of grid tied solar. He use to pay $500 a month in electric bills, now half the time he gets paid for the juice he generates through net metering. During the day his meter is always running backwards.
