Once you have sorted your objective then you can work out what you need to do the job.

So let's work our way through two of the most common uses that diy solar energy enthusiasts get involved in.

DIY Solar Energy - Electricity To Power Your Home

This is a growing market, as solar panel technology continues to improve and costs continue to fall.

Essential components of a diy solar energy electricity system

There are four essential components:

Solar panels

The sunlight falls on the solar panel array which results in creating a direct electric current(DC). The current generated will depend on the rating of the solar panel.

The current flows to the batteries via a charge controller. This important item prevents overcharging of the batteries and increases their life and performance.

Deep cycle batteries

The batteries receive the direct current from the panels via the charge controller. They either distribute the current to the inverter or store it pending times when the panel is not operating.

The solar inverter transforms the direct current from the batteries into alternating current (AC) at the required voltage for your area.

You can buy these items individually or you can purchase a kit that contains the parts plus an instruction manual for you to follow in assembling your system. Some dealers also offer phone support in case you get stuck.

In the interests of adding value we want to point you to a very useful resource that any prospective DIY solar energy person will find really useful. This site has an enormous collection of information, plans and manuals about all sort of solar projects, including solar electricity.

DIY solar energy - location issues

When you are setting up your system the location must be your number one concern.

In order to get maximum efficiency from your solar panel it must be placed so as to get maximum exposure to the sun.

If you live in the Northern Hemisphere then you need to place your solar panel in a south facing location. The panel should face due South and be inclined at the angle corresponding to the latitude of your location. The other way round if you live in the Northern hemisphere - inclined at local latitude, but North facing.

You also need to make sure that no part of your panel is shaded as otherwise its performance will be drastically reduced. The ideal is for un-shaded exposure between 9.00am and 3.00pm, the period known as "peak sun".

The roof of your house is usually the favored position but if it proves unsuitable in being able to achieve maximum exposure, you can get around it with a ground-mounted solar panel.

If you have any doubts about the location then we advise you to consult a local contractor who is experienced in locating solar panels. You may be able to get some free advice or a consultation for a very reasonable fee. Getting the location right is crucial to the success of your project!
