I always wondered if there are maintenance costs associated with solar panels. If they protect the roof from the elements, such as rain, snow, dust particles and maybe even hail, they absorb most of the impact energy themselves. Are they impact resistant or do they require regular maintenance and panel replacement?

Hi Mike, Most solar panels are manufactured to withstand some pretty heavy beatings from the elements, such as hail, high winds, etc. Additionally, solar panels generally require very little maintenance since there are no moving parts. A few times a year, the panels should be inspected for any dirt or debris that may collect on them. If a panel is damaged it should be replaced.
Can anyone tell me why I am observing Solar Panels on North facing roofs? I am located in the S.E. Pennsylvania area. I always thought they should face true South and be at an angle of the latitude where they are installed.

Hi Robert - Correct, if you’re in the United States (or elsewhere in the Northern Hemisphere), your solar panels should face true South. If you see a PV system on a North facing roof, it's probably because it was a last option since North-facing panels produce much less energy.
