A competitive pilot grant program that provided financial assistance to City-based building owners for installing solar hot water systems.
New York City is the most favorable market for solar thermal technologies in the state. With high energy costs and an abundance of sunlight, NYC is ideal for cost-competitive, renewable energy solutions. By using sunlight to heat water, solar thermal systems displace carbon-emitting, fossil fuels that are traditionally used to produce domestic hot water. For an average NYC family, solar thermal systems have the potential to provide up to 75% of their hot water needs.
Developing the solar thermal market has the potential to drive economic growth in New York City’s clean technology and energy sector while contributing to the City’s comprehensive energy efforts. Solar thermal technologies are mature and provide high energy production with relatively low capital costs. However, despite a strong opportunity, solar thermal has seen slow growth in NYC. The Solar Thermal Pilot Program provided a framework to identify and analyze market constraints and to develop best practices in order to foster a robust and sustainable marketplace in New York City.
NYCEDC launched the Solar Thermal Pilot Program in 2009, offering grants of 30% of installation costs up to $50,000 per solar thermal system to NYC-based building owners. The Solar Thermal Pilot Program had three primary objectives:
Through a competitive application process, NYCEDC selected several projects across a diverse spectrum of building types and locations. All systems installed under the program were equipped with performance monitoring equipment. Four systems were completed under the pilot. At the completion of the program, NYCEDC evaluated system performance and identified key next steps to facilitate solar thermal market growth in NYC.
