Do you have experience with solar power in your home?
Question by mamakin: Do you have experience with solar power in your home?
I’m doing research for our home. I’m wondering how long the solar panels last and if there is any maintenance. The dealers I’ve spoken to seem to offer a 25 year warranty and say there is no maintenance needed. What about roof repair or replacement with the panels in place? The dealers say that the roof can be accessed under the panels for repair and that they will increase the lifespan of the roof. Any info to share?
What do you think? Answer below!

Navitron tubes are the best price – cut out the middle man.
Why do you want P.V. cells? They are designed for off grid use really. Have you done the research on their environmental impact compared with getting your electricity from a 100% sustainable supplier? I heard the Yangtzee river dolphin is now probably extinct.
You have of course checked your (not so glamorous) insulation first.

I am a solar tech, so believe me when i say do not put pv panels on your roof because your investment will not be returned unless you have 40,000 sq ft of roof space to sell back your power to the grid. the installation costs of pv is, at a conservative rate, beyond $ 30,000.
Here is what you need to do. First, is your roof facing south? is in clear of trees? is it new construction or existing? If your facing south your in business. some states won’t allow tax benefits if your not facing south. You need to install a solar THERMAL system on your house. Depending on your sq. footage, it will determine how many panels you need. say you have 2,000 sq ft, and you want domestic hot water only, you only need 2 panels and a 108 gallon hotwater heater. if you install a solar heat exchanger in your hvac duct (recommended) you need a third panel. The payback for solar thermal (including tax benefit) is roughly 3 years. There is so much info i can tell you, but i don’t want to take up a ton of space on this post. The warranty is correct, the lifespan of the roof increases because you are shading the roof with the panels, so there is truth to that. but if your only putting 2 or 3 panels on the roof, its a small factor.

You should always repair the roof before installing solar panels. Most solar panels have a 25 year warranty as you stated but they last more like 30 to 40 years. As long as you are doing grid tie only without battery backup you will not have to bother with system at all. maybe spray a water hose on them from time to time to get the dust off. Most grid tie inverters now have a 10 year warranty so you might not ever have to do anything to them in your life time.
