Solar electricity


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.

Monitoring of two different type of photovoltaic materials and modules: One set is 2500 watts of rack-mounted First Solar Cadmium-Telluride modules, and the other set is 2560 watts of Uni-solar amorphous silicon building- integrated PV laminates. Both are mounted on the same 45-degree pitch standing seam roof, have the same solar exposure, and use the same model of inverter. See "PV Production" tab for live comparisons and for the past three days.

List of Eligible SB1 Guidelines Compliant Photovoltaic Modules Updated as of August 27, 2009 Updated as manufacturer's provide laboratory-tested data per Appendix I of the Guidelines for California's Solar Electric Incentive Programs (Senate Bill 1), Second Edition. Beginning July 1, 2009, only modules which are on the SB1 Guidelines compliant module list will be eligible for incentive in California.
