If you are considering solar, you’ll need to choose between a ground-mounted and a roof-mounted system.

Roof mounted systems
How large is your roof and what direction is your roof facing?
What is the slope of your roof?
Is your roof shaded from nearby trees?
How old is your roof? Think about the condition of your roof and shingles, and make necessary repairs/replacements. Remember that solar panels are warrantied at 25 years
Can your root support the weight of a solar system?

Ground mounted systems
What is the terrain of the land where you would like to install the ground mount?
