I've got 2 quotes for Solar panels and the first quoted for 10 panels with an immersion diverter at a cost of €9,100 before grant (€7,300 after) generating 3.95kWp.
He said I wouldn't need a battery as they only hold 50cent worth of electricity anyway.
2nd quote was for 12 panels 4kWp at a cost of €11,800 before grant, €8,800 after. This quote included battery and immersion diverter. This Company felt the battery was more important than the immersion switch.
2nd quote seems better but is who is correct? Also how long does a battery last. Are they like phone batteries that need replacing every 2 years?
