Solar And Wind Power For The Home

Solar and wind power in the home are probably the most widely used forms of alternative energy. When used in conjunction they form a totally green, round the clock hybrid energy system. They can even be wired into the utility grid connected system to supply the majority of your energy needs while the utility company functions as your backup energy source.

In a solar power system, the light from the sun is the source of electricity. Solar panels are mounted onto a roof, poles, or on the ground. The panels are lined with a semiconductor material that creates electricity when hit by the rays of the sun. Most mounts are equipped with motors that let you tilt the panels to face the sun as it moves through the sky.

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.

Wind power requires slightly less initial equipment costs as the bulk of the equipment cost is the turbine which is significantly less expensive than most solar arrays. The downside is that the turbine is going to have to be mounted fairly high off the ground on a tower style mount that is stronger but more expensive to install. An installation of this type will more than likely require zoning approval from the municipality that it is installed in and a great deal 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.
