How To Build Inverter Circuits at Home.

There are many aspects of an proper education in solar power, specifically with solar photovoltaic ( pv ) technology. There are the solar cells that make up the solar panels, how they can be connected to obtain the required results and what is known as the balance of plant ( bop ).

With in the balance of plant are components like the dc to ac inverter, remote monitoring, and the array structure. If the system has a energy storage portion to it, then there are additional components required for it.

Lets take a look a just one of these components, namely the inverter. Electricity from a solar cell or panel is in a polarized form, meaning it is what is known as direct current. The positive lead is always positive and the negative lead is always negative with respect to each other.

Household appliances however run on alternating current electricity. This means that the polarity of positive and negative with respect to ground is constantly changing. The rate that it changes is called the frequency. Typically the frequence of electricity around the world is somewhere betweeen 50 and 60 hertz. This means the polarity is changing or fluctating at a rate of 50 to 60 times per second.

So if the solar panels produce dc electricity, how do we change it to ac? The answer is a circuit known as an inverter ( or chopper). The inverter circuit chops up the dc voltage, inverting half of it with respect to ground and reproduces an alternating voltage. The inverter is a very important part of any solar pv power system. Commercial inverters typically have an inherent power loss due to the conversion from dc to ac of 4 to 5%.

To learn more about the inverter curcuit itself, you can easily build one to demonstrate the concept. In this video, you will learn how to design and build an inverter circuit. The basics that you will learn are exactly the same as in the commercially available inverters.

The best way to learn is to do right. Give it a try.
