The hot water heating system consists of a holding tank, a solar collector and equipment to circulate the water. The hot water heating system can either be a direct system or an indirect one.
In the direct system, the water that flows through the collector is heated. In the indirect system, the fluid heated in the collector is passed through a heat exchanger in the holding tank, thereby heating the potable water in the tank. The holding tank merely holds the water that has been heated, or is being heated.
The solar collector, which is usually located on the roof heats the water. Normally, the collector is a thin, rectangular box, which has a series of pipes running through it, painted black for maximum heat absorption. The water that runs through these black pipes gets heated.
For water circulation, there is either a low-powered pump, or it's achieved through convection, where the hot water rises and the cold water sinks. To achieve circulation through convection, the holding tank is placed above the collector, so the water rises into the holding tank, as it heats up and the cold water sinks down to be heated. A low-powered pump can also be used to circulate the water.
Heating your water for domestic purposes through solar power makes sense, as it is available all year round. This saves you utility cost on water heating, which makes up an average of 40 percent of the total household utility cost.
Solar Power for Building Heating
The sun, naturally, heats up buildings. It can also be done by special building design, or by the use of solar collectors. Passive solar heating occurs in every structure, but can be maximized when a building is specially designed to capture the sun's heat. It involves the use of special materials in the floors and walls of the building to store the sun's heat.
The building is designed with as many windows as possible facing in the sun's direction. This means that in the northern hemisphere the windows are south facing, and in the southern hemisphere, north facing.
Where a solar collector is used, the air is passed through it to heat it, then the heated air is passed into the house. The solar collector is also used to heat a liquid, which is then passed through the pipes, which are often laid under the floor of the house, heating it. The result: comfortable heat, free and natural.
Home With Solar Power
Most of our energy comes from burning fossil fuels, this creates a lot of pollution. The other problem with fossil fuels is that they are quickly running out, some experts have suggested that within 50 years our supplies of fossil fuels will of run out. That would cause huge problems for generating power and running vehicles. One of the best alternative methods of generating power so far is solar power.
Solar power is so good because it's reliable, clean and doesn't cause any pollution. These panels collect sunlight and convert the suns energy into electricity. This sunlight can be used in a number of different situations, be it a Rockwell factory or a private home. Solar panels are suitable for commercial and private use.
Reasons Why We Need Solar Energy
We have been dependant on fossil fuels for over a hundred years and few people have stopped to consider what it's doing to the environment. As a result we are now experiencing global warming and pollution. It's only now that renewable forms of energy are being sought, and this is simply because the reserves are running out. Solar power is one of the most popular forms of alternative energy.
The sun is very powerful, just so you understand how powerful it is the energy which is provided by the sun for a single hour is enough to power the world's electricity for a whole year. The sun is a fantastic and powerful resource which won't run out for a very long time to come. These renewable forms of energy are vital to the future of the modern generation.
Residential Uses Can Win Big with Solar Energy
Solar power isn't just for commercial use, Private homes can benefit from using solar power. Homeowners can utilize their roofs to capture energy to convert into electricity. This means that you don't have to use any extra land as you already have some space available that you're not using.
My favorite part of installing solar power systems is that any excess power you're not using can be sold back to your utility company. This will reduce your electricity bill even when you're not using solar power.
There are many different exciting applications for solar power. They are commonly seen on street lights, school crossing lights, and even traffic control systems. It's possible to power large gates and doors using solar power which saves the need to dig trenches and install cables.
Many developing countries have also benefited from using solar power as it can be difficult to get power to these locations. Lots of companies are working to make solar power an even more viable alternative to fossil fuels.
