Solar And Wind Power Generation

By Adrian Fletcher

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.

A solar power system will supply electricity generated by the rays of the sun. Solar panels lined with a semiconductor which generates electricity whenever the rays strike it can be installed either using a roof, pole, or ground mount. Such mounts are usually equipped with motors which let the panels be tilted during the course of the day so they can follow the sun's path.

The electricity generated by such systems is routed through a regulator/controller and then to an inverter to change the direct current to alternate current. Depending upon your installation, it may be sent to your battery array as direct current or to the electrical system in your home. When it is passed to your home, it can be used to power all your appliances just as the electricity from the grid may be currently doing.

Creating electricity is the same when using a wind power system, except that it is generated in the body of a turbine. The turbine is the huge, fan-like part with blades at the top of iron towers we sometimes see on hillsides.

In a wind power setup the wind turns the blades of the wind turbine the shaft of which is routed into a generator which as it spins creates the electricity. That electricity is then routed into your structure's electrical or storage system to provide power on its own or as a backup to your solar power.

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 connect a solar power system with a wind power system, each part can operate in tandem to compensate and complement each other. Wind power can be produced at any time while solar has its natural limits based on the hours that the sun shines and bad weather. Conversely bad weather for a solar system maybe good weather for a wind generator. Both these systems can be built quite cheaply depending on the amount of power you want to create. Some guide suggests this figure could be as low as $400. However a professionally designed and installed system would cost much more than this.

Make Your Own Windmill - Slash Your Electric Bill!


Traditional sources of energy could soon be a thing of the past. We need to change the way we get our energy and consider how much energy we are using in order to attain a more sustainable lifestyle.

There are many people who have already begun to do this. Previous problems with renewable energy have largely been solved due to new breakthroughs in engineering and technology.

With a good guide, even homeowners inexperienced in construction can create their own renewable energy sources, such as wind power generators. Wind turbines can reduce the average home's electricity bill by as much as 70-80%.
They can be built for as little as $200 using pre-used parts. The most expensive part might be a DC motor which can be as cheap as $30. You can find most of the materials you will need at your local hardware store and build it using a few basic tools.
The average American home can use from 14-20 kWh a day. If you start using a plan to conserve power, you will use much less than you are using now. Even if you don't have a lot of wind in your area, you should be able to reduce your power bill significantly with the use of a wind power generator.
