We put in a 90 watt PV system at our farm house about 3 years ago. They powered a deep cell battery and use an a 800 watt inverter. It gave us some power for lights and an electric blanket. We have a lap top computer that would cause the system to discharge after a day. During winter our power was very limited and our usage twice what it is during the summer.
We had ice damage two of the 6 cells. Our system is still working although we moved it to our barn after we got electricity put in last summer.
I can't imagine that a PV system would be less expensive on a month to month basis. After a few years the efficiency will go down. Batteries loose their potency.
