Home Solar And Wind Power
The two most popular alternatives in renewable energy for the home are solar and wind power. When the two are used in concert they can provide a constant energy source that is environmentally friendly. You can even mount them onto a system that is connected to a utility grid so that most of the energy to your home is supplied by the system and the grid is used as a backup system.
A solar power system supplies electricity that is generated directly from the sun’s rays. Solar panels which are lined with a semiconductor that generates electricity when the sun’s rays strike it are installed using either a roof, ground or pole mount. These mounts are often equipped with motors that allow the panels to be tilted throughout the day to follow the path of the sun.
The electricity generated through a solar panel is passed to a regulator/controller and then onto an inverter. the inverter converts the direct current to alternate current (AC). This is done because most homes run on AC. Once it is converted it can go into the home and used to power all your appliances and facilities. If it is not converted it can be stored in batteries as direct current.
Electricity follows the same basic path in a wind power system with the exception of the generation portion which takes place in the body of the turbine, which most of us consider the “giant fan” which spins away at the top of the enormous towers they are sometimes mounted on.
For a wind power system, the wind first turns the blades of a wind turbine. The turbine is connected by a shaft to a generator and as the shaft turns, electricity is generated. The electricity is then sent directly to the electrical system and can augment or substitute any solar power system you may have, or can be stored.
With wind power, the most significant cost is the wind turbine. Still, the turbine will be more inexpensive than the total solar equipment you’ll be required to purchase. The downside is that the turbine must be located in a spot far off the ground, usually needing to be mounted on top of a tower of some sort which can be expensive. The installation of solar power will probably require zoning authorization from the municipality and significantly more planning.
When you use solar power in combination with wind power, each part can contribute to the overall energy output. This can add up and put a significant dent in your utility bills if the conditions are right. Some guides to create such systems claim that you can build a hybrid system for the home for around $400. This is possible if you use discounted parts and do all the labor yourself. This may not be for everyone but because it is so cheap to put up, it may be a worthwhile project for any DIY enthusiast.
