Stony Brook School installed solar panels on the roof in the fall of 2010. The solar panels look like boxes covered with glass and they are mounted on the roof facing south to take advantage of the winter sun. Dark colored metal plates inside the boxes absorb sunlight and change it to electricity. The solar panels are examples of conservation of energy because they transform radiant energy into electricity. Solectria Renewables pays the town for the energy or kWh produced by the solar panels.The solar panel array on the school is a 1 kW array. This means if all the cells are working well and the sun is shining brightly, it would take 2 hours to produce the amount of energy contained in a fast food meal.

Use the link below to visit the Stony Brook School Solar Panel site. There is a graph at the bottom left that explains the relationship between the amount of energy the solar panel is generating and the irradiance or amount of light per area received by the solar panel. Also check out the Report (icon at the top of the page) that shows the dollar amount for the energy produced per day, week, and month.
