Solar Heating

Solar water heating is becoming one of the smartest ways to heat your house, cut down on your monthly costs for heating up water and do your part to help reduce your output of carbon dioxide. This is because solar water heating is a cost effective way to generate hot water to your home using the sun. The sun is responsible for all life on Earth, and generates a tremendous amount of clean, renewable energy that largely goes unharnessed. If, however, this energy could be harnessed, it could go a long way to reducing our use of fossil fuels, and coincidentally our emissions of greenhouse gases. Solar energy can be converted to electricity in the home, as well as a source of heat for water. Solar Water Heating is a simple way of making us of the energy from the sun for your private home.
How Does Solar Water Heating Work?

Solar water heating uses solar collectors or solar panels which gather up the sun's energy and use it to heat up water for your home. The panels will collect the sun's heat and the solar tanks store it for use in the home.

Essentially, there are three different types of solar hot water heaters that can help you to heat your home using the sun: the flat panel collector; the evacuated tube collector and the concentrating collector.

The flat panel collector is the most common and is comprised of an insulated weather proof box that contains an absorbent material which attracts the sun's heat and energy. Flat panels are usually attached to your roof. Very simple flat panel solar collectors are often used to heat a pool that uses solar energy. However, flat panel collectors can also be used to heat your home or provide you with hot water for showers or cooking.

Evacuated tube collectors use parallel glass tubes with an inner and outer tube that absorbs solar energy. The advantage of evacuated tube collectors is due to the fact that the outer tube is evacuated, does not contain any air, there is a minimum amount of heat loss through radiation. Concentrating solar collectors use troughs that concentrate the sun's energy onto an absorber tube which will contain a heat transfer fluid.

solar panel

If you are planning the purchase of a complete solar panel system or if you are shopping for parts to assemble your own solar panels you want to make sure to purchase the best solar panels for your individual purpose. This article puts up some basic information on solar panels to help you make the right decision.

One thing right at the beginning, there is nothing like "the world's best solar panels for everyone." It makes a big difference whether you want to generate electricity for your home and even feed surplus capacity in the power grid or if you want to charge a car battery now and then. And producing hot water from a solar installation needs actually a complete different technology. In narrower sense those so called "thermal solar collectors" or "solar collectors" are not even proper solar panels. So what's the difference?

Solar panels (photovoltaic panels, photovoltaic modules) convert shortwave radiation, e.g. parts of the sunlight, into electrical power. They consist of interconnected solar cells which are protected by a range of different materials. The surface is transparent and the solar panel is framed, mostly in an aluminum frame.

Hydroelectric power

Do you want the latest headline on Hydropower and looking for the ways to save energy, New-Energy portal can guide people about the appliances used in producing hydroelectricity from hydropower plants that can be established everywhere where there is a sufficent supply of water either a water reservoir or sources like- lake, river and many more. People can sense our services at any time of the day,week, month or years. Hydroelectric power is a renewable energy that can be replenished again and again to satisfy growing needs of people and can also be kept for the future. There is no danger of it being finished. We give people the tips about how to use the appliances used to set a hydroelectric plant in a way that it can last for long years. Maintainance required for the plant is not much after setup. There are various dams available almost everywhere, so the production of hydro power is quite cost effecient as there are not so much resources involved in it.

We discuss about the prices of the products used to set a plant and about the places which are best suited for the devlopment of plant like where the dam exists in plenty and it elevates the water or not, turbines are of best quality, generator for producing the electricity is available easily, water tubes to supply the water or the issues relating to appliances. We give our tips around the world and have a wide network for guiding people from large firms to small factories, countries to small villages. We give advice to people for storing the Hydroelectric power for their future needs and not wasting it as it is a precious resource. We discuss the issues relating to the use of non-renewable sources of energy and teach people not to use those in plenty as once they finish cannot be gained again. We tell the benefits to people about its non-polluting nature and without any emmissions of any harmful substances and gases and any fuel for its functioning.
