If we assume an all-in cost of £8000, and a ten year life (which matches the warranty), we get an annual cost of £800.

Add on interest at 5%, and the cost rises to £1200.

On top of this, of course, is the cost of solar panels etc, to produce the power in the first place.

Even then, it is highly doubtful whether the set up could provide anywhere near the amount of power I would need.

My annual electricity bill comes to to about £700.

Am I missing something?
