I have just two 325W panels that charge batteries during the day and the excess runs my three office computer systems. When the sun goes, mains electricity takes over (during the night and bad weather). I probably spent the equivalent of $1500. For this I get several hours of power when the mains electricity is offline (as happens frequently on our island). It's for convenience - not saving money.
