Ross Clark: How To Warm Your Mansion With Other People's Money....if you have the capital, a £15,000 array of 21 panels will earn you just under £1,500 a year in payments, all subsidised by electricity customers who don't have the roof space or can't afford the outlay. Yes, that is a return of nearly 10 per cent - tax-free. What's more, that payment is guaranteed for 25 years and is index-linked to the retail price index.
"A return of nearly 10%" is the promise, but it is on a depreciating asset. At the end of the 25 years the panels will be worthless (probably). So from your 10% remember to deduct 4% for depreciation (roughly). You might also want to deduct a little for the output figures being "optimistic", your mileage may vary.
Bang on about the madness of the subsidies but do get your numbers right.
