[QUOTE="ProDave, post: 522397, member: 6969"] I would start by questioning why you want PV and why you want so much? You do know there is no feed in tariff any more? So imho any PV install now has to be on the basis that you will be self using as much as you can to reduce your electricity import costs and trying to export as little as possible. If you take that view it can be viable, as long as you keep the costs down which probably means a good deal of shopping around. For that approach you do NOT need am MCS registered installer. And probably something like 5kW of panels split over your 2 roofs into an dual mppt inverter with an output limit of 3.68 kW under G98 with no prior approval needed. To go just over that to G99 will likely be a lot of expense and grief for very little extra gain. And if you are thinking of the "smart export" payment of about 5.5p per unit, do the sums, work out how much you will get paid and how long it will take to repay your costs. TIP it will not be worth it, and it is imho not even worth the extra cost of an MCS installer. (you need am MCS install to claim the smart export payment) Concentrate on cheap, simple and maximum self use and it is probably viable. [/QUOTE]
