DIY Solar Heating
In today’s age of increasing environmental awareness, alternative energy sources are receiving more attention than ever before. One of those alternatives that is receiving attention and fast improvement is solar energy. While many are familiar with it in its active form, many do not know that passive solar energy can also be used for heating or even cooling.
Solar energy is classified into two broad types. Most people are familiar with the active form. Ways to take advantage of these are detailed in the Power 4 Home system. The active form involves collecting the sun’s rays in photo voltaic cells and converting them into useful electricity. This can be used either to charge batteries or to directly power any number of appliances. Some energy is lost in this process, however, and while active solar energy can be used to heat or cool a home, this is not the most efficient method.
On the other hand, passive solar energy collects or redirects heat directly from the sun’s rays. As it is not being converted into electricity, more energy is available. The biggest disadvantage to passive solar, though, is it’s limited usage. Within the realms of heating and cooling, however, it is incredibly efficient. There is more energy available during low light conditions because less energy is lost.
As heat for homes represents a fairly large share of consumed energy, much environmental impact can be spared by adopting passive solar techniques. Using the sun’s rays this way would allow homes to be heated in really cold climates. Some of the methods used for internal heating are things like putting a window in areas that that receive a lot of sunlight. Other methods will incorporate a collector right into a building’s architecture to not only provide heat, but light too. Such a collector can not only heat but can also cause heated air to rise, drawing airflow into a space and making it cooler. The Earth 4 Energy ebook shows you how to make a solar panel.
Heating requirements are even present in warmer climates. Residential houses, for example, require a large amount of hot water when it comes to laundry, dishes, or bathing. Fortunately, solar energy is an excellent means of keeping water hot. Water can be heated amidst the collectors by placing a tank among them and this can heat enough water for most residential needs. It may still be necessary to supplement such a system with an electrical backup for days when no sunlight is available. However, each day that you don’t need electrical backup means a lot less impact is made on the environment as well as your wallet.
For many years, solar and other alternative energy projects have been built and installed by experts, many of whom charge prohibitive rates. As such, even the argument that such systems pay for themselves in time mattered little if the initial costs were too high. Fortunately, this is no longer the case, with many guides and other excellent resources available to anyone wishing to harness the sun’s power. If you’ve reached the point of being fed up with relying on a local utility, as well as watching your utility bills rise, it may be time to take action. Do it yourself solar heating and cooling technology can greatly lessen or can even eliminate totally the largest demand for energy in virtually any home.
