Who We Are

G&S Solar is a vertically integrated solar company. Our leadership team has been involved in the renewable energy sector for over a decade and has over 30 years of industrial, residential and retail real estate construction experience. Our roots are as a real estate developer, and in 2009 we began to build solar arrays on our own properties so that we could provide the benefit of lower electricity costs to our tenants. The program was so successful that we decided to expand, offering the opportunity to other businesses to lower their electrical costs and to promote sustainability; at no cost to them.

We are dedicated to finding creative solutions that provide value to our clients whether they are building owners, tenants, or owner operators. As property owners ourselves, we understand and respect the value of the real estate and work to the highest standards to protect it, and have created flexibility in our program to address these needs.

To date, G&S Solar has engineered, designed, and constructed over 150 projects, deploying over a half billion in capital. As a turnkey provider of solar solutions, G&S constructs solar arrays primarily for commercial & industrial businesses as well as government clients. In 2015, G&S Solar was recognized by Greentech Media as the 2nd largest private commercial & industrial solar developer in the nation.
