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
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 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
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
