After the Bali Climate Summit there was proof that governments can be slow tools for vital social change. Many scientists have proved climate change; the few sceptics have slunk off into the night. What few people can agree on is how we could or should tackle it.
You will only need two manual skills for your entire cheap solar kit construction. The first is a bit of woodwork knowledge to build the panel enclosure and mount the actual cells. The second skill is the electrical part which will require you to connect the mounted cells together. This really is simply wiring and connecting the cells in the correct way. Do not fear though any good renewable energy guide will have full instructions on both skills.
The basic measure of efficiency of any energy conversion system such as solar is simply the output power divided by the input power, a simple ratio that must always be less than 1. Simple. You just need to know those two numbers. Normally the output power is readily available. It’s usually the first spec given by the data sheet for the system or by the salesman. But what about the input power? Although the marketing types might make it sound complicated and mysterious, determining the input power is very simple.
One way to do this is by going to a store that specializes in home improvement. You can often find kits there that will give you all the elements you need for making the kit fotovoltaico. This makes the job easier but is not the least expensive way to go.
When you set up a solar system to use in your house, the government will give you ‘solar tax credits’. Now these solar credits are set up so that you basically pay less in taxes. Looking in the long run, if you set up a system it will eventually pay itself off because you will be paying less in taxes.
When you do not use up as much electricity, you can significantly reduce your utility bills. In a time when the cost of utilities continue to increase, this can mean a lot of savings. You will have to pay for the device and its installation but then once it is functional, you can have a source of energy.
Net metering is a great way to go and is connected pretty much the same way as off grid, except that a transfer switch must be installed also. The transfer switch automatically disconnects the solar power from the power company’s lines when the power company has an outage. This protects the linemen working on the power lines from dangerous high voltage coming from your solar power system. Even though you’re only producing 120 or 240 volts ac from the inverter, as it goes out to the power lines it goes through the transformer on the pole and steps up the voltage to a very dangerous level.
It may not be a very good idea to buy broken cells for your first project. But once you know the intricacies of the product and its assembly, you can certainly try incorporating these cells in your system. It’s not a high tech job once you have understood how to tie up the cells together in the grid to get optimum output. That’s it.
