Hi All, It's been a while although I do keep an eye on the group.
Here's the new ponderance... In Nov. 2015 I had 2 Solar PV ays fitted to our house 14 x 330 watt panels totalling 4.62kWp going through a
3.8kW inverter.
To date the system has paid for it's self (£7341) and as of December it's now almost £9K in profit over install costs thanks to 100% energy utilisation and FIT payments etc.
Winter production is a bit naff, so it got me to thinking I could add another small array of 4 or possibly 5 pannels on the S.S.E. end wall of the house to bring a bit more low angle winter energy into the equation.
The existing inverter has dual string input used by both arrays so wondering if I was to add a 2nd smallinverter, whether the output of that could be wired into the same 16A breaker (perhaps upping the breaker to 20A to give a little headroom) or whether I sould try and find an inverter with perhaps 4 MPPT inputs. I'm tentatively presuming if 2 inverters are wired into the same breaker they will both adjust to the mains voltage , phase and whatever to work in sync.
I anticipate a small vertical array would also benefit from the solar energy reflected form the the Estuary during the latter part of the day during Autumn through Spring.
Any thoughts or suggestions. I tried to get DNO to approve G99 originally but he wouldn't have it, hence G98 and 3.68kW limit, but I don't think the relatively small additional array would be a significant cause for concern..
Cheers Pet
