Solar Energy Systems at $0 Upfront

Solar PPAs, or Power Purchase Agreements, have changed the face of the industry. With a solar PPA, cover your roof with solar panels including a full maintenance plan at no upfront cost. Simply pay by the kWh of solar electricity delivered to your building at a substantially lower rate than your utility. Need a roof replacement? Solar companies in Washington, DC are contributing up to 100% of roof replacement costs. We also facilitate cash purchases.

Some of the most generous incentives in the country are here in DC. They’re currently at a high point right now, and we’re not expecting them to last very long, so please contact us to ensure you have an opportunity to take advantage of these attractive offers.

LED Lighting Upgrades

LED technology has revolutionized the lighting industry, offering 50-75% reduced electric consumption compared to traditional lighting. Because of generous utility rebates and falling manufacturing costs, we can help you access complete retrofits of antiquated systems with no upfront cost, through our shared savings program. We also provide free line item quotes if you’re interested in comparing prices to traditional lighting providers.

Water Savings

Water is a significant and growing expense for multifamily buildings. Buildings with a single meter can suffer from inefficient appliances and anonymous water wasters that drive costs up for everyone. We offer plans that analyze your current usage and repair or replace toilets, faucets, shower heads, etc. We cover the upfront investment and handle all maintenance efforts, then split the savings with you.
