CitiGreen is a company dedicated to saving property owners money on their electric bills by designing energy-saving solar systems. They offer a no-cost on-site audit to determine if a solar system is a good fit, and if not, they will let the property owner know. If the property owner decides to proceed, they can purchase the system with no-money-down financing or agree to purchase the electricity it generates for 10 years, saving 25% on their electric bill. After 10 years, the system can be bought for 15% of the original cost or continued to be used with a 25% discount every 5 years. After 25 years, the system is theirs to keep at no cost.
