Do They Customize System Size?

Stay away from installation companies that push the same deal for all house owners.

Panel strength, inverter type, and mounting parts shape how the system lasts.

Who Handles Installation?

A skilled in-house crew usually gives tighter control over quality than hired outside workers.

What Warranties Are Included?

What Happens After Installation?

Monitoring, support, and maintenance guidance should be clearly explained by the installation company

Can They Show Previous Projects?

Actual projects on which the company has worked earlier often tell more than marketing claims.
