Solar Battery Charger Circuits - Reviews and Ratings

Solar battery chargers help us use the energy from sun and they are very effective in giving us green and clean energy for our daily use.

The solar battery chargers are easy to build and they can be built with very commonly available electronic and electrical parts. The heart of a solar battery charger is the solar cells and these can be easily obtained from nay of the electronic stores of your local mall electronic division. The best place to get all you want to build your own solar powered battery chargers including the solar battery charger circuits is the online shops on the Internet.

The solar battery chargers are available in various types and shapes and the most commonly used ones are the solar AA Battery Chargers. This type is charge is very small in size and is very handy to carry with you. With this charger you can easily charge AA batteries without the electrical mains supply and can use the batteries to run your small electronic items like the Palm Pilots, walkman, radios etc.

The solar battery charger circuit to charge AA batteries is very simple and can be easily built by any person with little knowledge in electronics.There are many types of circuits available in the market and through various electronics buffs that have designed special types of solar battery charger circuits for their own use and have posted them for the benefit of others on the Internet. One of the simplest circuit diagrams for building solar powered AA battery charger is very trivial and simple in nature and can be used to charge a pair of AA or AAA sized rechargeable type batteries easily.

With this charger you can keep your Palm Pilot, Radio or your Walkman working perpetually and the beauty of it is that it does not need any external energy to charge the battery.The current required for charging the batteries is obtained from the solar cells and they have to be kept in the sun for a fixed period of time and the electric power generated in the solar cells charges the batteries.

With this charger you can keep your batteries charged by keeping the charger in sunlight. A day’s sunlight is all that is necessary to make your battery fully charged so that you can run your electronic devices.

The charger built as per the solar power battery charger circuit works at an open voltage of 4 Volts and can generate a closed circuit current of 25 milli amperes depending on the type of solar cell. With this current the AA batteries will get fully charged in about 8 hours of sunlight, and AAA batteries will reach full charge in about 4 to 5 hours. Each solar cell develops about 0.5 volts when exposed to sunlight and when 8 solar cells are connected we get a 4volts and this makes a current flow when connected to batteries that will be sufficient to charge the batteries.

Normally seven solar cells are connected in the panel and another variation to this solar battery charger circuit can be obtained by connecting the eighth cell with a diode for preventing the back flow of electric current to the solar cells from the Batteries in case of failing sunlight, and the eighth cell boosts the voltage to compensate for the drop in voltage across the diode.

If you want the charger to be operated in cloudy weather also you must have the arrangements for connecting another set of solar cells to the charger so that this becomes an all weather solar battery charger.In the present days we have a numerous resources on the Internet that are giving us opportunity to build our solar battery chargers.

If you are Do-It-Yourself type of person and feel happy in building your own electronic items and make them work as you wanted, then building your own solar battery charger is very easy now. With so many resources and help around by way of various discussion forums and websites specifically dealing with this matter you can confidently get into building your own battery charger.

The component needed to build your solar battery charger are very easy to source and you can get them everywhere including your local electronic shop. On the Internet you can find many websites and other online stores that are selling the solar battery charger circuit along with all the components as a kit and once you have these kits it is easy to assemble your own solar powered battery charger and you can have the happiness and satisfaction of having built your solar power battery charger.

There are many websites and other resources available on the Internet that make available all the materials that are needed to build your own solar battery charger including the circuits and schematic wiring diagrams with clear images showing the way in which these solar battery chargers have to be built. These websites are also offering the ways of interacting with the authors of the resources in case you have any doubts while building your own battery charger.

When so many persons who are interested in building the battery chargers discuss the difficulties they are facing while building the charger, you can get a clear idea of the technicalities in building the Charger by yourself. There are various resources for getting various types of solar battery charger circuits.

You can build a 12 Volt solar battery charger, A 9volt solar battery charger, an AA solar battery charger, a solar trickle charger, a solar battery maintainer or a solar battery charger control unit etc. The resources that are available for building your solar panels and the electronic components required for the building the control unit could be used to successfully build your own solar battery charger.

Some of the leading websites and online resources on the Internet that are providing all type of resources for building your own solar battery chargers are free and hence you can take all the necessary ideas for building your solar battery charger without paying any money and you can have your battery charger at cheaper rate.
