Solar Thermal Energy is the technology for harnessing the sun to produce heat and therefore utilize it for Space Heating, Space Cooling, Domestic Hot Water, Swimming Pool heating and even Electricity Production.
Solar Thermal Systems are divided in Low Temperature and High Temperature.
Low Temperature systems are used for Space Heating, Space Cooling, Domestic Hot Water and Swimming Pool heating.
High Temperature systems are used for Electricity Production.
In commercial and residential buildings, too, there are enormous waste heat potentials that could be exploited.
Cogeneration plants, solar thermal systems and district heating provide heat that is used primarily for space heating in the summer.
In the summer months, however, it can often not be used effectively. Adsorption refrigeration units make use of heat otherwise wasted – for cooling purposes.
That saves energy, protects the environment, and lowers operating costs.
These units are also eco-friendly since they use water as the refrigerant.
Geothermal HVAC (heating, ventilating, and air conditioning) brings a building in harmony with the earth beneath, taking advantage of subterranean temperatures to provide heating in the winter and cooling in the summer.
Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity.Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material.
Materials presently used for photovoltaics include momocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride and copper indium selenide/sulfide.
