Though I love the idea of solar, alternate energy sources etc, there is no way I'm putting them on my roof.
Many insurance companies are declining new risks with solar panels. Some are starting to non-renew policies with them as well.. The concerns are that in the event of a fire, water is not able to be poured on the roof and with the additional weight on the top of the structure, the firemen are being pulled from the home a lot sooner over concerns that the roof will collapse quicker. Also, there is concern of continued electric power throughout the home even though it has been shut.
How are the panels handled when it is time to replace your roof? Who takes care of the expense of removing them?
Is the contract transferrable? Not sure which solar company it was, but a friend was looking into buying an investment property, but it had solar panels, and there was a huge issue with the contract on them. He ended up backing out of the deal. He apparently wasn't the first person to walk away from the home for that reason.
