Solar energy is a renewable source of energy. Sun is a consistent source of power. So there will never be a sun-drought. Solar energy for home can greatly reduce the electricity bills. It is very useful. Solar energy is highly potential and it can easily reduce the oil prices. By using the solar energy as a substitute for oils in the automobiles, global warming can be controlled. It does not exhaust the venomous air pollutants and hence air pollution and global warming can be greatly reduced. This article is all about the use of solar energy in homes.
The major drawback of using solar energy in homes is that its set up requires huge initial investments. In Israel, solar energy is used in every house in the form of solar heaters. Israel is a hot country. Some days in winter are only cold particularly in the highlands of the Negev desert. Therefore, the climate is suitable for the implementation of the passive solar heating. This means designing the houses in such a way that during winter sunshine they can heat themselves and during the summer season they can remain cool. The basic components for a passive solar house in Israel are a well-insulated building envelope, a suitable area of south-facing windows, sufficient thermal mass to smooth out the large temperature swings and provide night storage.
In the colder parts of the country, the solar houses require large window areas but in the warmer parts, proportionately smaller window areas are needed. All the windows of the typical solar houses are designed using exterior blinds such that they can reduce the penetration of the unwanted summer sunshine. Sun-dried adobe bricks were used in the construction of the first passive solar house in Israel. When this house was fully constructed and the result was up to the mark, the key principles of passive solar design were adopted by all the architects all over the country.
Thus solar energy can be used in houses. It can effectively reduce the electricity bills and is very useful.
