Solar electricity allows us to harness the sun's energy to produce electricity without pollution, moving parts, noise, emissions, or fuel.
Photovoltaic cells are made of highly refined semiconductor grade silicon, the 2nd most common element on earth. Electricity is produced as photons of sunlight penetrate the silicon, exciting electrons into a flow. PV cells are connected together to make a module. These PV modules (Solar Panels) are the building blocks connected together to make arrays which can be scaled to power everything from a handheld calculator to several thousand homes.
The photovoltaic effect produces DC (Direct Current) electricity. This DC power is converted to AC (Alternating Current) electricity to match the American standards of AC frequency and voltage. The conversion is made by another important system component called the inverter. The array and inverter are engineered for efficiency and compatibility and designed to work together for optimal performance. The AC electricity can then be used to power your home, school, or business.
