In principle, you are right, but in practise, there are a few differences: - the homeowner gets the usage of the roof space for free - anything you can do yourself is cheaper than paid work - the calculation is different. The grid provides electricity 24/7. Your solar provides electricity, when the sun shines. Your solar is on your roof top, so no expensive lines are needed. And so on. So, if you can use your own solar electricity well, it is extremely cheap, as a lot of costs don't apply. |
