Solar Energy at Summit Naturals
by
Leo Siemion Jr.
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
4.8 Kw Photovoltaic Array
Installed 2006:
24 Sanyo panels @ 200 watts each
3 pole mounts
Fronius 5100 Inverter
5.1 Kw Photovoltaic Array
Installed 2011:
24 Schuco panels @ 215 watts each
3 pole mounts
Fronius IG Plus 5.0 Inverter

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
Locating Evacuated Tubes
Solar Geothermal
Parts of Solar Geothermal
in Glass Greenhouse• 12’Collector tube @ top of greenhouse• thermostatically controlled 15 watt fan• Two stacked 55 gallon drums (intake manifold)
• 27 4” perforated ABS pipes (totaling 520’)– In three layers in stone pit (10’ X 15’)
• Two stacked 55 gallon drums (exhaust manifold)

Ongoing Projects
40 yr. old electric tractor Wanted: old electric tractors !
Solar power to the batteries
Under the Hood Under drivers seat
Next project‐ Trombe Wall
Winter Crops Next solar project
