NOW TWO GREAT "HOME SOLAR ENERGY" and "HOME WIND POWER" COMPANIES TO CHOSE FROM

Solarenergy Measurement

Scientists measure the amount of sunlight falling on specific locations at different times of the 

year. They then estimate the amount of sunlight falling on regions at the same latitude with similar climates. Measurements of solar energy are typically expressed as total radiation on a horizontal surface, or as total radiation on a surface tracking the sun.

Radiation data for "solar power cells" or "photovoltaic cell" systems are often represented as kilowatt-hours per square meter (kWh/m²). Direct estimates of solar energy may also be expressed as watts per square meter (W/m²).

Radiation data for solar water heating and space heating systems are usually represented in British thermal units per square foot (Btu/ft²).
