SOLAR ENERGY
INTRODUCTION
Many pre-historic cultures used it to warm their dwellings, dry their clothes, and cure their food. The importance of solar energy was so great that most cultures revered

The simplest cells are used to operate wristwatches and calculators, and more complicated systems are used to light houses. PV cells are combined into modules called arrays, and the number of arrays used determines the amount of electricity produced. For example, a large number of arrays would be needed to generate electricity for a power plant (Kuecken, 1979). A power plant can also use a concentrating solar power system where sunlight is focused with mirrors to create a high-intensity heat source to produce steam or mechanical power to run a generator that creates electricity.
CONVERSION OF SOLAR ENERGY FOR USE
Producing solar power is just as simple as using the sunlight that heats the surface of the earth. Now, more than ever, it has become an important alternate energy source. It can be used in two different ways, as a heating source and as an energy source. It can generate heat, lighting and electricity. Understanding how this important energy source is produced is just the beginning.
Harnessing the Sun's

For instance, you can convert your outdoor lighting to solar. The solar cells are directly on the lights and can’t be seen by anyone. At the same time, you eliminate all costs associated with running your outdoor lighting.
LIMITATIONS OF SOLAR ENERGY
It is intermittent. Solar energy is only available when the sun is shining.
Some solar energy passes through the clouds. Solar panels produce some electricity even on very cloudy days. Intermittent is what powers net-zero homes. In the winter, the solar collectors capture less energy than the home is using. In the summer, the solar collectors can produce more energy than the home uses. At the end of a year, the home produces as much energy as it uses. Net-zero is good.
Batteries store solar power. Charge up the batteries on the sunny days and use that stored energy when the sun is hard to find. Many of the urban folks that are living without the grid, cloudy days and batteries get the job done. Solar energy is reduced when the sun is behind a cloud or on the other side of the world.
It is low efficiency. It requires large areas of
