Pearl School 1 kW grid tied system
The future of energy production by our civilization will be with renewable energy sources. Or there will be no future civilizations !
Solar produced electricity is silent, non polluting and renewable. It requires no special skills to operate; it is modular and versatile; it is very reliable and virtually maintainence free ( no moving parts ) and it can be installed almost anywhere facing south. Best of all the fuel is free.
Photo voltaic cells are made of a semiconductor material, usually silicon. They are photosensitive and produce and electrical current when exposed to light. Individual solar cells are combined to create arrays that produce larger amounts of power. The arrays can be sized to meet the power requirements of a building. A typical home system for utility grid tied connection is in the 2 to 3 kilowatt ( 8 to 15 k W hr / day in Michigan ). Our business has installed some of the first PV grid tied systems in west Michigan. We design, install and service solar electric system.
Prices range from $6 per rated DC watt installed on walk-on roofs to $7 per rated watt on pole mounted racks.
Commercial PV sytems larger than 45 k W at less than $6 per rated watt( depending on racking design )
All installations by NABCEP, Michigan licensed electicians specializing in PV grid tied systems.
