Renewable Energy

Our three solar arrays, now totaling 40.2 kW, have produced over 376,000 kWh of electricity, saving over $28,000 in the first 11 years.

New Raised-Seam Metal Roof

Due to a generous bequest, we were able to install a metal roof before installing the first solar panels. The raised seams allowed panels to be clipped without penetrating the roof. The light color helps reflect heat away so panels can work more efficiently. The roof has a 50-year life.

Production of Our Solar Panels

This graph compares the amount electricity produced by our solar panels to the amount purchased from the grid each month from May 2013 to May 2024. Monthly production peaked at 6558 kWh from mid-June to mid-July 2018. (Note that because it took almost six months to diagnose, order and install replacements for two failed inverters, electricity production dropped by almost half from early June to early December 2023.)
