Adding to the above post.

A person installs a solar system in their home. The house value increases by Rx thousands.
Later they sell the house, the sales price now having increased due to the solar system, by, one hopes, the depreciated cost of the solar system, not the replacement cost.

I won't buy the solar system, or at least wil take it over at a very reduced cost.

Why?

For the new owner, there is no warranty on the solar system, that one could be paying a premium for, not on the inverter, batts not the panels, no matter that still has a warranty period left for the original buyer.

Unless the equipment warranty can carry over, that is.

Something to make very sure of when buying a house with a solar system already installed.

Not to forget to check that it was installed correctly with a proper CoC ... by an Installation/Master Electrician.

My 2 cents.
