The Solar Water Heating method is more successful than the photovoltaic method because the photovoltaic method converts the light directly into electricity. This means that the photovoltaic method cannot store the electricity and is only able to function when there is sunlight2. So for the Solar Water Heating method if it was an overcast, rainy day, you would probably still have enough electricity to power all the essential requirements as the electricity would’ve been stored. A solar water heating system costs about R20000 so the cost is initially high but in the long term it is very efficient as your electricity supply is free. The government could also consider investing in a solar furnace.
Hydroelectric energy can be used to provide electric power to small towns and cities. Geothermal energy can be used to heat buildings or water and to power turbines to make power. Wind energy can be used to pump water and generate electricity. Solar energy is of the most resourceful sources of alternative energy. It is the most important of the non-conventional sources of energy, because it does not pollute the earth.
They can always keep collecting the power. No matter what people may argue about how much coal, natural gas and petroleum remains buried in the Earth, those fossil fuels will run out far earlier than the life of the sun ("Solar Power Vs. Fossil Fuels"). Home owners should invest in solar energy because solar systems have very dependable technology with little maintenance, they offer financial savings and they are better for the environment. Solar systems, also known as solar panels, are built to be very efficient and require very little maintenance. Technology has helped to improve the look and construction of the solar panels.
The function of an inverter is to convert the "DC" power (which commonly used in batteries) into an alternating current or "AC" power. AC is a kind of electrical power that computer, television and toasters use when plugged into wall outlet. The solar energy is one of the most important energy on the world because it is totally free, available widely, produces no pollution, no emission, no noise and no carbon footprint. so we must use this energy us can us possible to avoid the effect of other energy . The solar power systems that are used in our roof, produce the power directly from the sunlight's.
The heat is channeled through a conventional generator. This leads to the production of electricity. This electricity is used to run steam engines or turbines. The plants consist of two parts: the first part collects the solar energy and converts it into heat and the second part converts the heat to
Solar is getting more popular and even things like solar powered cars are being made. The Ford C Max energi has a solar panel on the roof to harness the suns energy and keep it going. Solar is much better energy source than anything else. If everyone has solar panels and batteries we would not need to worry about power being messed up with trees falling or digging in the ground. With solar we could all have our own “power plant”.
According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution. When the sun heats the panel, it generates clean energy which does not pollute the environment. All in all, the costs of solar power might not be applicable when it is certainly the best way for having a clean
Solar energy comes from sunlight, solar panels can turn sunlight into electricity. Out of these five energy sources, nuclear energy would be the most efficient source for producing electricity. First of all, nuclear energy would not emit dangerous gasses into the atmosphere when it produces electricity. Through the burning of coal, electricity is produced, but carbon dioxide, a dangerous greenhouse gas, is also produced. Unlike coal, nuclear energy would not produce carbon dioxide, it only produce water vapor.
In contrast, the indirect conversion of solar energy through CSP techniques involves the generation of heat energy and using the resultant steam to operate power generators (Hirschmann 36). Similar to the photovoltaics structure, this system does not have any environment-degrading emissions. The high-energy intensity obtained from the sun is the main reason why solar power is considered reliable and useful in establishing and maintaining profitable commercial projects with the main aim of increasing the local and global economies (Mahaney 112). For instance, various scientific experts have proved that the sun is able to provide the world with enough power to run all domestic and commercial projects for a year by shining for one hour. This fact is the underlying principle behind the recent operations of the National Center for Photovoltaics (NCPV).
In use, solar energy produces no emissions. One megawatt hour of solar electricity offsets about 0.75 to 1 tonne of CO2. Benefits of solar energy Solar energy is not only sustainable, it is renewable and this means that we will never run out of it. It is about as natural a source of power as it is possible to generate electricity. The creation of solar energy requires little maintenance.
