Technology: Solar Hot Water, Radiant Floor Heat, Solar Electric
The sun is the primary energy source for this off-grid home and it is harnessed by both solar thermal and solar electric systems. A 4-collector solar hot water system heats water for domestic use and also supports the radiant floor heating system. The home's electricity is generated by a 5.4 kW photovoltaic array with battery storage and an Outback inverter.

Technology: Solar Electric, Solar Hot Water, Radiant Floor Heat
Providing for the domestic hot water and the home’s concrete slab radiant floor heating are four 4x10 AET solar hot water collectors, which can supply an average of 160,000 BTUs per day. The electrical load is met through a 2.6 kW photovoltaic array (20 130 Watt Kyocera modules) with a 48 Volt, 900 AH Deka Battery for storage.

Technology: Solar Electric, Solar Hot Water
Solar electric grid-tied system with battery back-up. The array consists of fifty-four 130 watt Kyocera modules and a Sunny Boy grid-tied inverter for a total output of 7020 watts. The battery back-up uses a Sunny Island 4200 watt inverter with eight 770 amp hour batteries wired at 48 volts DC. The HVAC system is a “hybrid’ which includes a 4 collector solar thermal system that assists a high efficiency heat pump, radiant floor heat in the master bath and basement, and an on-demand propane water heater for back-up.

Technology: Micro-Hydro
At the heart of this system is a Thompson and Howe generator which is rated at 4500 watts. About 700 feet of penstock delivers 80 psi static pressure to two nozzles that shoot the water into the turbine. Transformers, a 1105 Amp hour battery bank, inverters and relay controls work together to provide power for the home’s appliances, hot water, and other electrical needs. When the system is producing more electricity than is being used the energy is dumped through several exterior space heaters from hot water tanks as heat.

Technology: Outdoor Wood Furnace
The Classic 4030, from Central Boiler, has a firebox measuring 40”x 30”x 26” and a 140 gallon water jacket. Pumped through extremely insulated Thermopex tubing to the mechanical area in the home about 100 feet away, the heated water is circulated through radiant floor tubing. Three separate zones are controlled through Sundance’s Versacor distribution panel. In addition, the heat also provides for domestic hot water.

Technology: Solar Hot Water, Radiant Flooring
Four flat plate solar collectors provide free BTUs for the home’s water heating. Within the home’s poured concrete floors, the radiant heating system consists of an extensive looping of pex tubing that carries hot water which is heated partially by the solar thermal system and by a high-efficiency Prestige propane boiler.

Technology: Solar Hot Water
The two collector system is very visible as it is angled away from the roof line to face south. There has been a 20-30% reduction in electricity usage that he has seen since installing his system. Heat is delivered to the hot water tank in the basement, and it also ties in to the HVAC system through a heat exchanger to preheat for space heating.

Technology: Solar Hot Water
Seven solar pool heating collectors are mounted on the barn roof adjacent to the home’s pool. Each 4 X 10 collector has a thermal rating of 39,000 BTUs a day, and transferring this heat to the pool is straightforward. The pump circulates pool water through the filter and the water is automatically diverted so that it flows through the many small passages of the solar collector. While passing through the collector, it is warmed by the sun. This warm water then flows directly back into the pool. When the pool has reached your desired comfort level, the water then bypasses the solar collector and returns directly to the pool.

Two 4 X 8 flat plate collectors provide a great amount of heat to their hot water system, reducing the amount of electricity for water heating. Mounted flush on the roof is a solar electric system that produces an average of five kilowatt hours a day. According to Ben, these systems helped reduce their electric consumption from an average of 23 kilowatt hours a day to an average of seven.
