I have just received two 550 watt panels to charge my Bluetti EP500 PRO in the event of a major power outage like an earthquake. I plan to take out 6 rails from this flat roof and install the panels flat but want to be able to raise them to better face the sun when needed. Southern exposure is from the right. They are 90" X 45". Any suggestions? Want to get them flat to eliminate problems with the HOA. The whole structure is metal because of our desert location HOA rules allow no wood.
