Go Solar

Thinking of going solar? Project Sunroof is a quick and easy Google tool that estimates the solar potential for a rooftop solar array for your home. Enter your address, and discover your energy savings potential. 

The Marin Solar Program is a County of Marin outreach and education program that can also help you decide if your home would be a good candidate for solar. Staff can answer questions, evaluate bids and educate you on the other solar incentives and financing.

Contact the Building Division for more information on solar permitting. 

Purchase Clean Energy

All Marin County residents have the opportunity to choose how much renewable energy is in their electric service. Customers can opt in to one of Marin Clean Energy's (MCE) renewable energy programs - Light Green (60% renewable) or Deep Green (100% renewable). The Town of Tiburon proudly opted up to Deep Green service in 2017.

You can also purchase solar power through MCE. MCE's solar program, Local Sol, provides 100% of energy service from locally produced solar power. 

PG&E also offers several programs to purchase renewable power. Customers can opt for PG&E's Renewable Choice program, which allows customers to subscribe to renewable energy form a specific community-based project within the service territory. PG&E's Solar Choice program allows customers to purchase either 50% or 100% solar energy. 

Upgrade Your Home

Home Energy Score is a program developed by the Department of Energy. When you sign up for the program, a trained Home Energy Score Assessor will visit your home and assess your home's energy efficiency. Once you get your score, your contractor or Home Energy Advisor can help you prioritize the smartest investments for your home and teach you about other local incentives. 

Green House Calls will send two trained Youth Energy Specialists to your home to look for resource conservation opportunities, install new equipment to help you save energy, water, and money, and give you personalized recommendations for even more savings. 


The State of California has introduced a financing program called GoGreen Financing to assist customers, contractors and energy service companies in meeting the State's energy savings goals. 

The financing program aims to increase accessibility and financing of energy efficiency projects. Customers are able to access financing at attractive rates and terms that allow them to upgrade their buildings, reduce energy usage and help to improve comfort and indoor air quality.
