Create A Home Solar Power System To Help Save You Money


By Steven Johanson

If you are interested in saving money on your power bill or want a to leave a lower carbon footprint on the earth, home solar power may be the answer for which you are looking.

Solar cells have been available for many years and are a way of producing electricity on site. Many persons that use solar energy may have no other source of electricity, while others are still connected to the normal power supply, but use their solar power to reduce the cost that they spend on electricity. Still others use solar electricity with some other form of power that is produced on site. They may choose to use a generator that is powered by fossil fuels or a wind turbine to produce supplemental energy as needed.

If a home is going to be dependent totally on solar energy, you will also need to plan for those times when sun is dark. This requires a large bank of batteries that can store the energy that is produced but not used during the day. It is often possible to store enough electricity during the day to operate lights and appliances during the evenings and nights.

While solar energy is useful for many things, there are some places there is not enough power produced for the use. Heating and air conditioning are two of these areas. For heating you may want to consider active or passive solar heating of the home. This makes use of the public power supply nice for the additional energy.

Some homes that depend on solar power also use wood for heat. If you have a few acres available, it is possible to have your own woodlot and use black locust trees that self perpetuate after cutting. As little as five acres can perpetually provide all the wood that is needed to heat a home.

Cooling can also be a problem. If humidity is not a problem, evaporative coolers may work. In high humidity areas, cool air from a basement can be used to cool a home. In addition, there are some interesting plans that use a cooling tube buried in the back yard to cool outside air for the home.

Within the past few years, solar air conditioning and heat pumps have been introduced. While these units are somewhat expensive, prices will likely drop as they grow in production and in use. Development of these units is going to be a key to growing the use of home solar power.
