From initial consultation to flipping the switch, the entire process of going solar can take a few weeks or months. Getting permits, inspections and connecting your system to the grid can impact the timeline. But installing panels on your roof typically takes 1–3 days.
Start with a free, no-obligation in-home Solar Consultation. A Trinity Solar Expert will confirm that your home and roof are solar-ready, analyze your utility bill to estimate how much you could save with solar, provide a detailed quote, and share purchase plan options, including $0 down options, plus details about state incentives.

Trinity solar and battery systems come with up to a 25-year parts & labor guarantee. Your Trinity Solar Expert will review your coverage during your Solar Consultation.
It depends how much energy your household uses and how much sunlight is available. During your free Solar Consultation with a Trinity Solar Expert, we’ll look at these factors and calculate the number of panels your home needs.
If a big tree is shading your roof, it can impact your ability to go solar and you might need to remove the tree. We know—this can be a tough choice! We love trees and don’t suggest cutting them down unless it’s necessary to make your solar system successful. If it makes you feel any better, our 140k+ solar customers have prevented the production of more than 3 billion pounds of CO2, equivalent to planting 24.5 million trees.
