Affordable Solar Power, Creating Renewable Energy with Solar Panels
A renewable energy source for the future
I am doing a physics experiment where I need to compare the efficiency of the two. Solar panel for radiation>heat water and solar cells for radiation>electrical energy.
Can anyone recommend me some cells and panels which have lots of information about their performance, efficiency etc?
Many thanks!
When building homemade solar panels are some steps you need to do. First you need to connect each cell in a sequence (6 cells with sequence). You have to make six strings to produce enough voltage to produce a significant amount of energy. Once he made chains need to connect each other.
The first thing to do to connect the chains of cells together is to make sure you have all the tools together. When connecting the wires together, you need a piece of something that will be used for solar panel face (I use plexiglass as it is relatively cheap and will not break like glass). The blade should be 2 "X 4". This is a couple of inches longer than we need, but then they get together, you can trim the excess. Other tools you need are a soldering iron, the bus wire, flux, and some silicone.
If you are using a shell of Plexiglas on one side of paper to expose the surface. Put all chains of cells in the sheet and allow safe space beyond them (I use a small piece of wood. Once they are spaced correctly apply a small Silicone touch to keep each string in place. The reason for this is so you do not have to worry about things slide when all welds. Do not worry by fusion or plexiglass … I used this method for more than 50 panels and nothing went wrong.
Now is the time to leave your soldering iron and heat. While is heating up the place a small stream in each of the strings that are to be connected. The flow is important because without the solder does not "stick" to the cell, and instead, keep the soldering iron.
Cut a bus cable (as the wire tab, but more than they can handle more power) and put between each chains to be welding together. Touch the solder to it and apply a little solder. Do this for each of the six strings.
Congratulations! You successfully connected all the strings of solar cells together. Before you usually spend the paper in front and a flashlight on it while connected to a multimeter to ensure that everything is connected correctly and that produces energy.
I built my own solar panels and a wind generator and saved well over $30,000. I get a cheque from the power company because I produce more energy than I use.

Power from the sun is a green power source. This is simply because it can be replenished and it does not cause any environmental problems.. This source of power is achieved by transforming sunshine into electricity through the of use of solar cells. Other green sources of energy include wind power, hydroelectric power, biogas and thermal power.
There are three basic methods for using this form of green energy source namely passive, active and by using photovoltaic cells.
When we refer to passive solar energy, nothing is transformed into a different form. What happens is this case is the building’s design which helps to avoid heat loss and gets the most out of the warmth of the sun during the day.This can be most helpful in colder climates where heat is a necessary requirement for comfortable living spaces. In warmer climates, this design will help reduce the heat from the sun and therefore keep the building cooler than would normally be possible. .
This type of methodology can also be used in homes because studies have shown that this can lower the heating requirements by as much as 80% with minimal cost. This would mean that people do not have to turn on the air conditioner or furnace that often. Now if everyone does that, then we don’t use up that much electrical power which unfortunately we obtain through non-renewable sources.
The next technique which is active sun power is actually the first method of changing the sun’s rays into heat. People ought to realize that there tend to be some specific limitations to this particular one and just about all it could very well accomplish would be to ensure that you have hot water.
The 3rd tactic is the large scale edition and this can easily power an office or even an entire residence. This is accomplished with the aid of solar cells that transform the sun’s rays into electrical power. The tiniest kinds in existence can be found in hand calculators and wrist watches with big ones planted over huge plots of land.
The only restriction to this particular eco-friendly power source is the point that it is only able to create electrical power whenever the weather conditions are good and the sun is shining. Should it start raining, then almost nothing is collected and transformed. When this occurs, the auxiliary system is used until the weather becomes more favorable.
However, disregarding this fact, scientists and even students themselves have designed photo voltaic driven vehicles. The National Aeronautical Space Administration has dispatched satellites into outer space which are powered by solar cells. A completely functional airport can easily operate on its own using solar power even if it is located in the midst of the frozen tundra.
Therefore people today can see the magnificent capability of solar energy, did you happen to know that a kilowatt of solar energy can produce 5.5 hours of electricity daily.The more cells that you have doing the job, the more power and the longer the electrical energy will last.
