Research

Pescom is involved in research for renewable energy, i.e. active solar, wind, and wave power. We have a research house in Hilo, Hawai'i where experiments are done with off-grid living and zero dependence on public utilities.

House specifications:

- 12 x 75-watt Siemens solar panels

- 4 x 150-watt Siemens solar panels

- 16 L16 batteries for 1,440 amp hours (amph)

- Trace SW 4024 inverter

- 3 kilowatt Onan generator

- 8,000 gallon water tank to hold collected rain water

The Trace inverter converts DC voltage into AC which allows the house to be wired conventionally using 110 AC. The house has standard appliance such as an electric refrigerator, dishwasher, and washing machine.

The Onan generator runs on propane and is in place for backup power. Since its inception in 1996, the house has not been required to use the generator.

Due to the rainy nature of Hawai'i, it was wondered if there would be enough energy generated from the solar panels on a daily basis. Research has shown that even on rainy, cloudy days, they are still charging approximately 20 amps of power.

On sunny days, the house generates power at levels over 50 amps.
