You can generate hot water for use in showers, baths in your home with solar water heaters. In any climate you can have solar water heating systems and the fuel that they use is free sun light. Solar water heating (solar thermal) panels shouldn’t be confused with solar electric panels which produce electricity from sunlight.
Solar water heating systems are categorized in two different types; first one is the active one which has circulating pumps and controls another one is passive one which doesn’t. Some form of external power is required for operation in active systems. Active ones are also two types; direct circulation systems and indirect circulation systems.
Direct circulation systems work well in climates where it rarely freezes and in this system pumps circulate household water through the collectors and in to the house. Indirect one heats the water then flows into the house and mostly they are popular in climates prone to freezing temperatures. In this system plumps circulate a non freezing fluid through the collectors and the heat exchanger. When we compare the prices of passive and active solar water heating systems passive ones are less expensive than active ones but they are not as efficient as active ones.
Solar electricity means generating cheap, green electricity from the sun. It is possible to create electricity with using solar panels and the sun. There are technologies that directly transform the sun’s energy into electricity and known as photovoltaic. If you know how to use photovoltaic for your business or own house you will save plenty energy and money by using Photovoltaic electric system.
All you need to know is that solar panels on your house roof or in your garden take the sunlight and produce electricity. The electricity is captured and fed into an inverter to boost low voltage direct current into high voltage alternating current electricity.
This 240 voltage current will be compatible with your household appliances. It is free electricity. Just you need to pay for photovoltaic panels. Panels are necessary because cells in panels take sunlight in and produce electricity.
PV cells come in variety of colors and shapes. You also need inverter otherwise electricity which is produced by panels is low voltage and not useful for you. You also need new electricity meter. Then you will have all the time free electricity. The stronger the sunshine the more electricity is produced but even in cloudy days you can still generate some electricity because photovoltaic cells don’t need direct sunlight to work.
The electrical power created by solar photovoltaic panels which can be used efficiently in houses, vehicles, boats and more… The location of the panels is important. More electricity is produced from the sun if the sunlight comes to the panels without any blocking. (i.e. mountains, trees or buildings).
Solar electricity may be practical and cheap for the conditions where mobile power is needed, or places frequently face with power cut. But it should be kept in mind that the solar electricity systems may be expensive parallel to the need of electricity.
We may advantage from the sun power during the year. In order to generate solar electricity, photons from sunlight are absorbed. This process is successful, even in cloudy days or during bright nights but only in few amounts. The panels may be positioned on a roof, on the ground, or on a pole.
The amount of solar electricity may change due to strength of the sunlight. In order to have constant electricity flow, solar electricity should be kept in batteries. The constant power is essential for using the solar electricity for electronically devices requiring mains electricity. Also, attention should be given not to discharge the batteries entirely or contrarily overcharge them. This may give damage to the batteries. A controller is a helpful device at this point. Another important thing is an â€œinverterâ€ which takes the DC (low voltage) from the batteries and converts as AC (high voltage) for the devices requiring mains electricity.
Solar Electric Panels
Solar electric panels mostly produce electricity that can be used for lighting but it can also be used to heat buildings and it has to be tank of water beside.
Solar panels can be classified in two different categories as liquid and air. According to average temperature range over which they are intended to be used each of these two categories also can be sub-classified as low temperature, medium temperature, high temperature collectors.
What are solar panels?
Solar panels are known as photovoltaic cells or panels as well. Solar panels actively convert sunlight to the electricity with harvesting it. The surface of the solar panel has solar cells which are arranged in grid plan. During the daylight hours these solar cells collect sunlight to convert it into electricity. Solar panels store the energy in batteries for our use and with this usable energy it is possible to meet the everyday needs for modern life. Panels allow you to either provide a hot water supply or generate electricity because there are two types of panels first one is the solar hot water panels and second one is the solar electricity panels.
Just one single panel can produce only a limited amount of power so installations have to contain several panels for enough electricity. Mostly on the roof or in sunny garden areas installation includes several solar panels, batteries, inverter and interconnection wiring for producing energy. The basic element of solar panels is pure silicon. Silicon makes an ideal platform for the transmission of electrons and solar panels are created by combining silicon with some other elements that do have negative or positive charges. Solar panels can be used on different types of buildings in all shapes and sizes because solar panels come in different shapes and sizes.
What is solar energy?
Solar energy is the power from the sun and its lights up our days and also it heats the earth, us, our homes etc, it grows our food.
Everybody and everything deal with solar energy. Stored solar energy forms fossil fuels such as coal, gas and oil. It also means “using the sun’s light and energy to provide electricity, heat, hot water etc for homes or industry”.
Before using sun for generating power we have used it for drying food and clothes for centuries. 150 million km away Sun and also its energy is astonishingly powerful. Solar heat and light are two different categories of energy from the sun. Solar heat energy is used to heat water, air etc for businesses and homes.
Today it is possible to see solar thermal collectors in many sunny areas such as roof of the buildings, gardens without trees etc. It is also possible to convert solar energy into mechanical energy today. The energy from the sun is free and lasts for decades so many people prefer to reduce energy costs with converting free energy from the sun into electrical energy. Solar energy doesn’t require any fuel. If you like to reduce your home energy cost you need to know all about solar energy. Solar energy using is clean and it helps to protect our environment. It never pollutes our air. It works silently and doesn’t smell.
It will be right to say sun’s energy is vital for the earth and it is the future of world’s energy needs. Solar energy is the best investment available today because it guarantees a return on money that you will.
