School Power Naturally Program - New York State Energy Research and Development Authority - Case Study
When complete, School Power Naturally will represent the largest program of its kind in the country. The project provides funding from NYSERDA of approximately $24,000 for each school and requires the schools to provide an additional cost share of $1500. After a competitive selection process, 50 schools have been selected to receive identical 2 kilowatt solar arrays.
Solar arrays by themselves offer little educational value. They don’t move and often are placed on building rooftops where they cannot be seen or touched. Data monitoring and computer displays, designed to be fun and educational, offer an excellent way to bring the solar array to life in a fun and engaging way. Demonstrating the interplay between environmental variables, such as irradiance and temperature, and system performance offers a rich environment of multidisciplinary learning opportunities.
