I have a rental property and use a 230-Volt 6-Amp Pool Pump.I would like to use a solar panel to run it when the house is empty, using mains power when guests are here.The building is in the Caribbean so plenty of sun!!I wanted to run it quot;directand not use batteries. Is this possible??What size panel would I need? A DC invertor too??Thanks!!
You can buy a solar pool pump with all the equipment you'll need.
Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.
