Energy Matters reports on the effect of solar panels on the re-sale value of a house. The decade-long study investigated 72,000 homes and compared the price of those with solar to those without.
The study showed that house values were increased by the addition of solar panels. What's more, the increase in value was larger than the cost of the panels - especially in the case of existing homes.
So i guess the lesson is that solar panels will always be a good investment. If you're staying put for a long time to come, then you'll save plenty in electricity bills. If you decide to sell up and move, then you'll get a better price for your house.
