Solar Energy: The Benefits Of Solar Energy

The benefit is that it “‘turns back’ your electricity meter as it is fed back into the grid. If you use more electricity than your system feeds into the grid during a given month, you pay your power provider only for the difference between what you used and what you produced” (Salkalachen 1250). This is saying that when a person is selling that extra energy from that other power source, then a person is saving money on a person’s power bill because the electricity company is paying them for their energy.

The main reason solar energy is getting so big is because of the advantages of the use of solar energy. The main advantage of solar energy is that the power source is infinite unlike fossil fuels which are limited. Scientist currently predicts that in the next forty to fifty years fossils fuels will expire. Also solar energy is cleaner, rather than fossil fuels, solar energy doesn’t give off pollution and also is water efficient. Nuclear power plants and gas power plants use up so much water to cool the plant down, solar panels however doesn’t need water for anything.

Solar Energy is also very efficient. The panels could be charged during the day and when there is no sun, the energy from the previous day is already stored. “You can use home solar panels as a partial or full source of electrical energy for your home. These residential solar panels can be tied into the electric grid, or you can produce all energy you need and live "off the grid". Solar systems that are tied into the grid can even sell unused electricity back to a power company”.

Despite generating electricity with fossil fuels for years and years there is a much better way that does not harm the environment. Using Solar panels does not produce any carbon dioxide unlike fossil fuels that “produces huge volumes of carbon dioxide, which is a gas that influences the global climate” (“Solar Power Vs. Fossil Fuels”). Having the choice to get power in a new way that saves the environment, home owners should not have to think twice about trying solar. In fact if home owners collect some amount of watts per hour on Monday, that will not reduce the amount of solar energy a home owner can collect on Wednesday or any other day that week. They can always keep collecting the power.

All in all, passive energy is one of the two types of solar energy. Active energy is when solar power is turned into electricity using a technology called Solar Photovoltaic (PV) or into heat by Solar Thermal. Unlike passive solar energy, this type of energy is not directly changed into the forms. Semiconductors are used in Solar Photovoltaic. They create electricity when hit by sunlight.

Most importantly they decrease the electricity requirements. As compared to traditional ac’s they are cheaper. They do not produce any green house gases. SOLAR AIR CONDITIONERS PRINCIPLE A solar powered air conditioner works on four different principles: 1. Solar thermal cooling ac’s 2.

This can limit how much power will be saved for the future. One of the most important advantages with solar power is that is creates absolutely no pollution. Solar panels require very little maintenance is required to keep the solar power running. The number of advantage that is associated with using solar power it ways out the disadvantage. Solar energy is a very useful energy source to contribute to solve the issue of human induced climate change.

CHAPTER 3: SOLAR PHOTOVOLTAIC ENERGY CONVERSION 3.1 Introduction to Solar Energy Solar energy is that energy which is gets by the radiation of the sun. Solar energy is present on the earth continuously and in abundant manner. Solar energy is freely available. It doesn’t produce any gases that mean it is pollution free. It is affordable in cost.

They use an array of solar photovoltaic (PV) cells (or modules made of cells) that convert sunlight into electricity. The electricity either goes directly to an electric motor powering the vehicle, or to a special storage battery. The PV array can be built (integrated) onto the vehicle body itself, or fixed on a building or a vehicle shelter to charge an electric vehicle (EV) battery when it is parked. (Green nature) Next, “Hydroelectric power is the largest source of renewable ... ... middle of paper ... ...,000 light bulbs that use 100 watts (Energy Story) Even though you can only use windmills in areas that are fairly windy they are still an effective way to produce without burning fossil fuels. Luckily, there are many means alternative energy sources to conserve the earth's limited natural resources.

Introduction Actually, by solar cells we can change sunlight to electricity directly. Every day, the light of sun hits your roof's solar panels with photons (sunlight particles). These photons are converted by solar panel into electrons of direct current (DC) electricity. The electrons flow out of the solar panel into an inverter and other electrical safety devices. The function of an inverter is to convert the "DC" power (which commonly used in batteries) into an alternating current or "AC" power.
