FINAL BRAND INDEX SCORES WERE DETERMINED BY WEIGHTED AVERAGES OF THE FOLLOWING THREE MEASURES:
Survey Data: How our readers ranked each company’s sustainability compared with other companies on our list.
Sentiment: Ranking in terms of how favorably consumers see the company compared with the other companies on our list.
Mentions: Ranking in terms of number of positive mentions compared with how the other companies scored.

Holding steady. After three years at the top of our Readers’ Choice survey, a tumultuous,
controversy-filled 2018 knocked Tesla subsidiary Solar City out of the top spot and a footstep
behind SunPower. We’re happy to see our friends at Jinko making a strong showing on the chart,
catching up with some of the biggest players in the U.S. photovoltaic market.

maintained its place as a go-to pick for roofing, but fellow 2019 champion EcoStar slipped a few spots
due to lack of public comment. The same can be said for EnviroShake, last in Mentions but in the top
one-third in public response.
