I’ve been working for hours on the campaign, so this is my break:
I emailed the solar company yesterday and finally said yes. That is the end result of a long torturous period of talking to different companies about potential installations, and looking at a total of 4 different roof locations, before eventually sadly concluding that they would have to be ground mounted.
What I’ve said yes to is an array of 10 PV panels, in 2 groups of 5, in a portrait orientation, so as to minimise the width of the array, as the shading from the trees and the house take place at each end at the start and end of the day, thus minimzing overall shading. This means the array is likely to be about 5 meters by 3 meters in size, and means there is less room for parking, which is fine because this is the money I’d otherwise have bought a newer car with anyway :D
The panels themselves will be schuco MPE 215 (215watt) modules. The inverter will be a sunny boy, with a remote monitoring system called a sunny beam. If I can find out how to code a blog page widget to show current solar output, I will :D.
The installers (no doubt optimistic) estimate is for it to generate 2.15kwp which is 1,792KWH per year. Thats £740.19 in feed in tariff and a saving of roughly £268.33 per year. Thats a total of £1,009.02 per year on an investment of roughly £11k. Thats a ROI of 9.1%, or ‘much better than any bank account’. Now you see why I’m doing it :D If the power generated was 50% lower, it’s *still* a good investment…
HOWEVER. All this assumes that I get a) Listed Building consent and b) Planning permission. I am optimistic, but planning people can be very prickly. Quite *why* anyone could object to them is beyond me as you can only see the site from physically in our garden, plus they don’t even touch the house. I’m still nervous about getting an answer though.
I’ve wanted solar panels for about 10 years now, but I won’t believe it’s really happening until I have them working. The plus side to all this is the proposed site is right outside my office window, which is kinda cool.
Now back to debugging…
