What home solar installers actually charged, per watt

Each installer below appears in Lawrence Berkeley National Laboratory's Tracking the Sun data with at least 15 customer-owned home systems installed from 2019 to 2023 and a reported price. We show the median installed price per watt, the middle range, the typical system size and how many installs the data holds.

Past prices, not a quote. The data ends with installs in 2023, and prices are before incentives. We do not rank installers by price or quality: the list is ordered by number of installs reported, and a lower price does not mean a better installer. Sponsored placements are labelled and never change the order.

Common questions

What does price per watt mean?

It is the total installed price divided by the system's DC size in watts, a way to compare quotes for different sizes. See how to compare quotes per watt.

Are these current prices?

No. The data ends with installs in 2023, and prices are before incentives. Use it as a reference point, not a quote.

Does a lower median price mean a better installer?

No. Price depends on equipment, roof, system size, batteries and local costs, and says nothing about workmanship or service. We do not rank installers.

Why is there no phone number?

The data set does not include contact details. Search for the company by name and check its license with your state's contractor licensing board.

Why is my installer not listed?

We list installers with at least 15 priced, customer-owned home systems from 2019 to 2023 in one of eight states. Others may be missing, reported under another name, or in a state where the data has no installer names or prices.

Where does the data come from?

Lawrence Berkeley National Laboratory's Tracking the Sun, compiled from state agencies, utilities and other programs. See how to read the data.
