I'm sure I've got the MCS certificate squirrelled away somewhere. The panels are over 6 years old. It's just the inverter that's new, because the old one failed after 6 years. The good news is that with the longer days, the peak power has already gone up to 2.4kW on one day. The new inverter is a lot fancier than the old one, with extensive data logging to see what it's doing.
I've also got a lithium ion battery with the new system. To be honest, I'm not sure if it will ever pay for itself in terms of saved electricity bills - the batteries are still too expensive. But it does mean that I can post to this forum at 2.45am, while still running on solar power!
