                           Ireland is perfectly suited to solar energy. Ireland lies between 51.5°- 55.5° North. Insolation levels in Ireland are comparable with countries such as France, Germany and Austria, our neighbours in Northern Europe. Germany and Austria have well developed markets for solar heating.

HOW IT WORKS Typically a solar panel is mounted so that it faces the sun. This can be on a roof or at ground level or on the wall of a building. The solar system contains water which may be supplemented with antifreeze. As the solar panel is warmed by the suns rays, the fluid is heated up and is pumped through a water heating tank. The solar fluid transfers its heat to the water in the tank. It then returns to the solar panel to be re-heated. The water heating tank may be fitted with two coils so that another fuel can supplement the solar thermal input. Solar thermal systems may be used just for domestic hot water or for central heating as well. We will be happy to quote you for either application and also for complementary technologies for other renewable energy sources such as wind or biomass. These can be used in conjunction with solar and enable you to be independent in relation to your energy needs.

 

SOLAR PV

Photovoltaics (PVs) are arrays of cells containing a solar photovoltaic material that converts solar radiation into direct current electricity. Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide/sulfide. Due to the growing demand for renewable energy sources, the manufacture of solar cells and photovoltaic arrays has advanced dramatically in recent years.

For best performance, terrestrial PV systems aim to maximize the time they face the sun. Solar trackers aim to achieve this by moving PV panels to follow the sun. The increase can be by as much as 20% in winter and by as much as 50% in summer. Static mounted systems can be optimized by analysis of the Sun path. Panels are often set to latitude tilt, an angle equal to the latitude, but performance can be improved by adjusting the angle for summer or winter.

 

WIND ENERGY

Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.
