Solar

SOLAR POWER COMES IN TWO FORMS – BOTH ARE RENEWABLE SOURCES OF ENERGY

Passive solar systems are used to heat water on rooftops and use thermal energy  to efficiently boost the performance of home waterheating systems.  The photovoltaic arrays now appearing on rooftops use light energy to produce electricity that offsets that which is drawn from the power grid.  Two distinctly different technologies that both utilize the same dependable resource –our constant Hawaii sunshine.

Passive solar is simple technology that captures radiant heat from direct sunlight.

There are advanced thermal systems that use the heat from the sun to produce steam pressure from large boilers heated by an array of targeted reflector mirrors.  Several of these large-scale facilities are planned for, primarily, dessert areas on the mainland.

Locally, Sopogy, a Hawaii-based company produces a compact solar-concentrator thermal system. Their SopoNova system is a concentrating parabolic trough solar collector designed for distributed generation installations that include rooftops. The technology operates similarly to conventional parabolic trough systems used in California since the mid 1980’s but modified to reduce the physical size and is similarly manufactured to fluorescent lighting luminares or automotive parts. The package ships flat and unassembled. The system uses an integrated 270 degree tracking, customized stands, and controls.

Hybrid technologies that utilize both thermal and photovoltaic energy may be the most promising of all.  Compact dual systems are being developed for home, roof-top installations.

Photovoltaic system can continue to produce electricity for 30 years before wearing out.
