How Solar Works

Solar power, also known as photovoltaics (PV), is the production of electricity when a substance is exposed to light. The most common substance utilized in the industry, since its introduction in the 1950s, is that of the semiconductor called crystalline silicon.

A solar module, or panel, consists of individual solar cells connected electrically in series to achieve a higher output voltage. These cells are then sealed together by:

• Encapsulant – greater protection against higher temperatures, UV exposure, and water damage
• Tempered glass - rated specifically to withstand hailstones traveling at 50 mph
• Backsheet -  added protection against the elements and electrical insulation

Aluminum Frame - ensures structural stability and longevity

A solar cell contains two different variations of this crystalline silicon layered within each:

• Silicon infused with phosphorous resulting in a negatively charged (n-type) semiconductor
• Silicon infused with boron resulting in a positively charged (p-type) semiconductor

 
Photons, from sunlight, knock loose excess electrons located within the n-type semiconductor as they contact the surface of the cell. These electrons then travel to the p-type semiconductor through a small depletion zone, located between the two, and fill in “gaps” within its composition. This electron transference creates direct current (DC) electricity which can then be harnessed and converted to alternating current (AC) electricity for use throughout your household or business
