How To Build Solar Panels
The Best Low-
The price of electricity is climbing as oil prices nudge up above $100 a barrel once more. Turning to home energy production with wind and solar is a natural response: not only would you save on your electric bill, but you would also help the environment and reduce dependence on dwindling oil and natural gas.
But browsing the price of an installed rooftop solar power system can bring on its
own version of fear and loathing. A rooftop solar system capable of supplying all
or most of your home's energy needs can cost as much as a new car.
So how about installing the system yourself and saving on the labor costs? That will bring the price down, sure -
Just as the solar panels are the biggest part of the cost of a solar system, so the biggest part of the cost of solar panels is the price of photovoltaic cells. Solar cells are the individual silicon wafers with electrical tabs attached that go into making up a solar panel. Each cell converts sunshine into electricity, but it takes many solar cells to generate enough energy to be useful on a household scale (although many small applications like solar-
The key to making
You will need some tools, but probably nothing that you don't already have at home except for a soldering iron. It's recommended that you get some practice using this item if you don't already have it. You will be soldering connections between solar cells so that they are connected serially, negative-
So how much work are we talking? To produce a simple solar system containing several
solar panels and install it to produce electricity for your home will require two
or three days dedicated to the project -
How much can you save? It isn't hard to find materials that will let you build solar panels for less than $200 each, with each panel capable of generating about 18 watts of power.
The entire system, fully installed, for a typical house would cost no more than $3,000,
which is less than half of the cost of a kit capable of generating a similar amount
of power, and only a fraction of the cost of a fully-
An average electric bill can cost $200 a month or more (and rising), which means the system would pay for itself in less than a year and a half.
