This kit, (panels, inverter, isolator switch, meter, wire, connectors, roof mounting brackets costing £2500 (about $3000 US)) was purchased off Ebay.
I expect generation of about £500 worth of electricity through the year – even here in England – so for a £2500 investment that’s a 20% ROI – for approximately 20 years. Not bad at all.
Not the best video but I learned a lot – not least that it’s not a particularly difficult job – and hopefully there are some tips for DIYers. The more solar the better!
