Sooo.. at long last I’ve just made the first deposit payment for getting my much-talked-about solar panels installed. This has been at least 5 years in the making. ‘Sheesh’ etc…<\/p>\n
This is what I’m getting:<\/p>\n
A 2.15kWp system.<\/p>\n
10 x MPE 215 PS05 schuco modules. Total area 14.96 square meters installed in 2 rows of 5 at ground level. (roof is unsuitable).<\/p>\n
A sunny boy SB2500HF-30 Inverter.<\/p>\n
The quote says that it should generate 1845.56 kWh per year. They calculate that if I use all that power (and I will) it will save me \u00a3230.70<\/strong> a year based on 12.5p\/unit electricity cost (bound to rise dramatically over the lifetime of the panels). (however my current provider charges 11.52p\/unit).<\/p>\n edit: just investigated and in the last year we used 4,134 kwh, so this set of panels is slightly under half my total usage.\u00a0 I bet that’s because we have an electric cooker…<\/em><\/p>\n In addition, the feed in tariff would pay 1,845 * 43.3p = \u00a3799.13<\/strong> a year.<\/p>\n Total income is thus \u00a31,029.82<\/strong> per year.<\/p>\n Total installation cost is \u00a310,608<\/strong>.<\/p>\n Assume the panels are worthless after 20 years, I’ll earn \u00a321,216<\/strong> over that, which would be a gain of \u00a311,000<\/strong>. I can see that the performance of the panels will degrade by then, but I strongly suspect energy prices will rise enough to more than compensate. I also can’t see the feed-in tariff being reduced or abolished for existing installs by any government of any color.<\/p>\n Obviously the panels may not generate the described amount. There is some shading in the garden (bah!). And I’m not going to cry into my tea if the output is below maximum.<\/p>\n Interestingly, the cost of the panels+inverter dropped about \u00a31,000<\/strong> in the last 8 months. Also of interest is that VAT on them is charged at only 5% (although tbh, if the government really want to kickstart a domestic renewables industry that needs to be 0, not 5%).<\/p>\n Fun fun.<\/p>\n No point in me talking about my new game today.
