PhotoVoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photo electric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current is produced which is "electricity".
Solar cells produce Direct Current (DC). An inverter is used to convert the DC power to Alternating Current (AC), which we use in our homes.
In addition to solar modules and inverters, a racking system is needed to support the solar array on a roof or directly on the ground. On a new line, a roof mounted solar system is normally attached to the rafters with stainless steel lag bolts.
A ground mounted solar system is normally supported by footings filled with concrete. Electrical hardware is also necessary to carry the current from the solar array to the main service panel in case of a grid-tied system.
All solar modules and micro inverters we install come with a 25 year warranty from the manufacturer. Today's solar modules are very reliable. Most modules have an estimated lifespan of well over 50 years.
An Interesting Fact: The sun is by far the world's largest power plant. The amount of energy we receive from the sun in just one hour is enough energy to supply the entire world with electricity for one year.
