Solar

Solar Radiation: Incoming solar energy from the sun.

A certain amount of solar radiation entering the earth’s atmosphere is absorbed and scattered. A direct beam of radiation (direct sunlight) comes in a direct line from the sun (sun rays). The difference with diffused radiation compared to direct radiation is as follows: diffused is scattered out of the direct beam by molecules, aerosols, and clouds. The sum of the direct, diffuse, and ground-reflected radiation arriving at the surface is called total or global solar radiation.

The UK and Ireland experiences a large proportion of cloudy overcast days throughout the year and consequently 55% - 62% of the radiation reaching a horizontal surface at ground level is diffuse. It is diffuse radiation that provides most of the daylight in our rooms, particularly those with north facing windows.

By harnessing the sun’s natural energy, you could typically reduce your household C0₂ emissions by more than 500kg each year. That extra efficiency translates directly into savings, cutting your energy bills dramatically. Taking into consideration the spiralling prices of domestic energy this may be the optimum time to consider the benefits of renewable energy.

Why Solar?

Solar is an environmentally friendly, high efficient source of energy that reduces the output of harmful gases and provides a variable alternative to conventional fuels. And now directives like the Code of Sustainable Homes are making such systems a must-have for new homes.
