What better area to do this than in home electricity on which we are so dependent on a daily basis.

This article runs through a couple of relatively practical options in the DIY solar generator field - some of them more realistic saving options than others, depending on a number of factors.

The first of these DIY solar generators is sometimes called a flat plate collector. In this system you will find liquid-filled pipes which are sealed and fixed between sunlight-absorbing plates.

During the course of the day the liquid heats up and is circulated via pipes through the water tank of the household. This process heats up the tank water. The effectiveness of this fairly simple process depends to a great degree on the minimization of heat loss as the heated liquid flows towards the household water tank. As an indirect circulation system it can work well under freezing conditions.

The next DIY solar generator is a beast of a different kind, but becoming increasingly popular among the more serious do-it-yourself enthusiasts - especially those with milling and workshop machine experience: it is the amazing, quiet, and very effective Stirling solar generator.

Just a bit of background first about this incredible engine. It was first built around 1816 as an alternative to the popular, but often dangerous steam engine of the time.

Stirling engines work on the basis of temperature differentials in the air chamber. The air (or other gas such as helium) inside expands and contracts and in the process drives a power piston.

The beauty of these engines is that they can be powered by just about any external heat source, and some models will start chugging along at a temperature differential of less than 5 or 6 degrees.

This is where the solar Stirling comes into play. Stirling engines can be set up to work very effectively in converting solar energy via a parabolic dish or solar concentrator. They can reach efficiencies of 25% or even higher.

The downside is that not everyone will feel up to building their own Stirling solar generator, and to make this a truly DIY solar generator they will probable need to be made availabe in a kit format more generally accessible to homeowners.

And this is where the DIY solar generators of the third kind come into the picture: solar cell panel systems. Homebuilt solar panels are gaining a great deal of popularity, thanks to their many benefits, not the least being that just about anyone enthusiastic about saving costs - and saving the environment - should feel comfortable building them.

Solar cell systems work on the photovoltaic principal which converts sunlight into electricity. They are efficient enough to make economic sense, and a relatively small array of panels can supply sufficient electricity for a medium home.

There are excellent, detailed plans, guides and instructions available, aimed at the first-time builder who wants to be taken through a step-by-step process, with clear explanations at every turn, such as that found at www.energy-saver-diy.com.
