How is Solar Energy used:
• Photovoltaic
– 4.8 Kw– 5.1 Kw
Solar Hot Water
‐ evacuated tube
Geothermal
‐ stone pit in glass greenhouse‐ soil in high tunnel

Pole Mount vs Roof Mount
Pole Mount
• Easy snow removal
– more electric production
• Easy to adjust tilt– more electric production
• Lower Temperatures
– more electric production
Roof Mount
• Difficult snow removal
– less electric production
• Difficult to adjust tilt– less electric production
• Much higher temperatures
– less electric production

Domestic Solar Hot Water
Evacuated tube assembly
‐drain back
Drain back tank (10 gallon tank)‐distilled H2O
Thermal storage tank (80 gallon tank)‐open loop to boiler
Differential temperature control‐auto senses difference
between temperature in tube array and the 80 gallon storage tank
