Israel is located in the geographic latitude of about 30 degree north. Around 2000 kilowatt hour per square centimeter of solar irradiance is incident on this country on an annual basis. There is a scarcity of natural energy resources in this country so it generates the required electricity with the help of imported coal and oil. According to the recent surveys, the total electric generating capacity of this country is about 6.5 GW that represents 1 KW per capita. But in few years, this value has increased drastically as the requirements of electricity in each and every field have increased many folds. In this adverse situation, Israel has leaded the way to use the solar energy effectively.
Solar energy Israel has a wide range of applications in numerous sectors. Solar energy is currently used for the generation of domestic hot water, passive polar space heating and photo voltaic rural lightning. Advantages of solar energy Israel is remarkable as it has contributed significantly towards many fields. Hence, we can say solar energy is a renewable source of energy that has been harnessed since long times by humans to uplift the mankind.
According to recent surveys, the major purpose of solar energy Israel is the manufacture of solar water heaters that covers the roof-tops all over the country. All the major domestic units have 150 liter storage tanks and a 2 square meter flat panel. The work of flat panels is to collect the solar radiation and heat the water. The hot water is then passed to a pump less gravity driven loop. Annual average efficiency of these types of system is approximately 50%. This system is highly advantageous as it saves about 2000 kilowatt hour per year in electricity costs and raises the temperature of a tank full of water by about 30 degree Celsius above its initial point in an average day. This means that there is no need of electrical backup heating coil during most of the days of the year. Without the implementation of backup coil, water can be heated to serve different purposes. Therefore, solar energy can be used in several fields without investing huge sums of money.
