I have 2-75watt solar panels and 1-120watt solar panel, an inverter, and charge controller for 400watts. I am in a rented place now and would like to know how to reduce my electric bill. I have used my 2-75watt solar panels to pump water from a well before at my last place but don't have to worry about that now. The rented place has a electric stove, refrigerator about an 18cu. ft. (not mine), and a new washing machine. I have a dryer but try to now use it much. I am currently using about 774 KWh per month.
