Our Technology - Solar Technologies

Passive solar technologies are means of using sunlight for useful energy without use of active mechanical systems. Such technologies convert sunlight into useable heat (water, air, thermal mass), cause air-movement for ventilating, or store heat for future use with little use of other energy sources. Passive solar technologies include direct and indirect solar gain for space heating, solar water heating systems, the use of thermal mass and phase-change materials for slowing indoor air temperature swings, the solar chimney for enhancing natural ventilation, and earth sheltering. Solar heat can also be converted to electricity.

Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. The systems may be used to heat water for a wide variety of uses, including home, business and industrial uses.

Solar heating systems typically include an auxiliary energy source (electric heating element or connection to a gas or fuel oil central heating system) that is activated when the water in the tank falls below a minimum temperature setting.

Photovoltaics involve the conversion of sunlight directly into electricity. Photovoltaics is the worlds fastest-growing energy technology with a cumulative global production currently estimated at 12,400 megawatts.
