types of solar conversions

eco energy the right choice.

Solar PV

Solar PV (PHOTOVOLTAICS)
Solar PV is the use of photovoltaic (PV) panels create electricity directly from the sun.

PV uses photochemical reactions to create an electric current.
Primary component is silicon or other semiconductor.
Cost per KWH is around $0.21.
Average system cost is around $8.00/KWH Provides electricity directly.
Must se batteries to store electricity for evening use.

Solar thermal

Solar Thermal
Solar thermal is the use of the sun to heat water for use within the building.

Solar Thermal relies on thermodynamic heat transfer to warm fluids.
Primary components are glass & copper tubing.
Cost per KWH is around $0.10.
Average system cost is around $4K.
Only provides hot water, does not provide electricity directly.
Stores hot water in thermally insulated tank evening.
