I've done alot of homework on them. I've settled on a 24volt system with at least three 240 watt panels . Thinking of adding a small wind turbine tied in. Looking for opinions from those with experience. System will need to handle one full time resident..on demand propane water heater..monitor heater...basic lights..basic outlets.. Does the turbine keep the battery bank up in the short sun/no sun months ? I will have a generator on site to charge the system if needed...but hoping to avoid that with the wind turbine.
