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

    “This system can distribute heat more effectively throughout a dwelling because of its pumps and fans,” (Mongillo 42). The Active Solar Heating System requires three difficult solar subsystem steps that explain the process of how to convert energy from the sun in the simplest form (Mongillo 41). The Active and Passive Solar Heating systems have many tools that are involved in the long process, but a solar photovoltaic cell helps to speed up the process (Mongillo 41). Another type of energy device is solar photovoltaic cell, also known as PV, converts sunlight directly into electricity. In 1954, the photovoltaic cell was founded, scientist found that silicon produced an electric charge while it was in direct sunlight (Mongillo 42).…

    Greenhouse gases built up in the atmosphere trapping heat, therefore causing the planet to heat up. According to the Solar Energy Industries Association, “solar energy is a renewable resource available within every geographic region of the U.S. with great potential to significantly reduce our nation’s ghg emissions” (SEIA). Using solar power releases zero greenhouse gases into the environment. Integrating this environmental saving solar panel into our home’s electrical system is a way to help the environment. Using the power drawn from the solar panels to our energy efficient appliances will reduce greenhouse gas emissions.…

    One of the chief producers of photovoltaic energy is the solar panel. Each new generation of solar panels produces more energy cheaper than the previous making it a viable solution to energy problems in poor rural areas as well. Solar panel’s low cost and reliability enable those living outside major urban areas of a developing country to still have a bright light when it gets dark or when the power grid goes down. Its technical features reinforce…

    • Where Your Solar Panels are Located Disadvantages of solar energy in SA are where you place your solar panels. This will determine how much electricity you get. If installed in an area that doesn’t get much sunlight, you will still get some energy but you won’t be able to get the full benefits. However, during cloudy days, there will be solar energy but you’ll get significantly more in a brighter environment. Installation of more panels will be required in areas that have least sunlight or installation of a lower number of panels in brightly sunlit…

    Using the money you were going to use on electricity spend it on the batteries to save solar energy for the night. Another drawback to solar energy would be that it can only be used during sunny weather. As stated by David in "Solar Power-Advantages and Disadvantages”, “only work when the sun is shining”. This problem can also be easily fixed. Solar energy is a “renewable source” as stated by author Rinkesh in “Solar”.…

    Solar cells were used in streetlights to turn independently on and off, using light. The first actual solar panel was invented in 1932 (Fox, 1997). Photovoltaic modules convert sunlight into DC electricity when sunlight shines on them. Modules are made of glass and either crystal or non-crystal silicon cells. More modules can be added at any time for more power needs.…
