Passive Solar

Active Solar Heating

Solar Collector

• Glass on outside• Absorbent on

inside• Circulating Fluid

Generating Electrical Power• Concentrating

Solar Power– Trough systems– Power towers

• Heat exchanger plus steam turbine

• Photovoltaics– Small-scale

(buildings) kW production

– Large-scale (utilities) MW production

• Photoelectric effect
