Solar Energy Heating Power

SOLAR ENERGY HEATING POWER

Solar heating is usually powered by photovoltaic cells on the roof of the home, ideally south facing at a 20- to 50-degree angle. There are two forms of solar heating, the more common using photovoltaic energy to heat water, which can then be used for radiated heat and swimming pools. In Scandinavia, passive solar energy is used to blow hot dry air into the home, both warming and dehumidifying. The limited energy that is produced through photovoltaic cells and their reliance on strong sunshine means that solar heating will not meet the demands of the average household in winter, when heating is required more urgently. While the efficiency of solar power can lead to significant savings in the long term, the cost of a specialist to install the cells, as well as the price of the technology itself, is a significant deterrent to most homeowners.
