Here are some pictures of mine Sunpower 5.16k system install. The panels along the ridge I want to prop up to level. The installer said he would need a permit for a base to do what I wanted. I wanted it high so I could get the early morning sun and I knew I would change the angle after they left.
The three panel in the front of the picture are my old solar hot water and still work great.
Radiant barrier installed it block 97% of IR heat which keep about 50% of the heat out of the house
I installed Radiant barrier and insulation and it made a big difference.
