We've only had the current system for a week, so I'll speak to the system we had on our old house - No roof issues. No leaking. We had them removed to repair the roof and it was painless. Just called the company and they removed it and then reinstalled. Unsure how that is going to work with our new system since we own this one, but the company has promised the same thing (easy removal and reinstall should there be a need). Of course, that's only good so long as the company is around.
This was going to be my question about if you take the panels with you when you move. So it sounds like they are easy to remove and reinstall somewhere else? I’m a perpetual nomad, so was wondering about that aspect. Saving up 20-30k and then leaving them behind a few years later seems daunting to me! :/ But obviously doing what’s better for the environment is important!
It can be extremely expensive to take them with you. You have to pay for the removal and then the design, permitting, and reinstallation on your next property. The system is also designed for your current home so sometimes you are trying put a square into a round hole.
Special Snowflake. Technically, we had solar panels when we bought our house 6 years ago, but they were only for our hot water heat. When we replaced our hot water heater 2 years ago, we also got rid of the solar panels. When we replace our roof sometime in the next few years we will also be adding solar panels that will be tied to the grid with battery backup.
We're currently looking in to it, our power company is offering incentives and they were out last week to assess if our house is a good candidate for it. I'm keeping my fingers crossed that it can be done.
