subject: Bring Solar Power To Your Home With Poly Crystalline Solar Cells [print this page] Sometimes it feels like everyone is yelling that the sky is falling. The global warming reports make many people feel like they need to start doing something to help the earth and this is where the green movement comes in to tell you how you can start being a greener individual. The truth is, however, that the green movement is nothing but a continuation of the environmental movement- only more trendy. Being truly good to the earth only means that you rely on yourself more when it comes to living your life and this self sufficiency can translate into big cuts in your budget when it comes to things like energy. Ask anyone in the middle a hot summer how much their energy needs cost and you're likely to be given a large number, but with the advent of solar panels some of that cost can be alleviated. Solar panels can be made with a number of different solar cells, but the cheapest and most prevalent is a poly crystalline solar cell.
Poly crystalline cells have a mosaic like appearance precisely because they are made up of a number of different crystals that are embedded into blocks of silicon. The smoother panels that you have most likely seen are monocrystalline based, while there is yet a third type of cell called an amorphous cell that has an additional layer of material that films the panel.
While poly crystalline solar cells are less efficient than single crystal cells, they are easier and cheaper to produce which is attractive to potential buyers that are faced with prices in the high thousands. Also, although they may be less efficient than other cells they last just as long and allow almost anyone to bring solar power into their homes.
Prices can vary depending on the brand you decide on, but will range between eight and twelve dollars per watt of power. Each cell, also on average, has an efficiency rating on twelve percent meaning that twelve percent of the sunshine that hits a cell will be subsequently converted into electricity.
The rate of efficiency means that for every bit of sunshine that comes into contact with a solar cell, twelve percent will be converted into electrical energy. Going one step further, this means that for a square meter of space, on average a hundred and twenty five watts of electricity is created.
Efficiency is based on an average and when it comes to purchasing solar cells and panels you should know where this average comes from. The set of environmental circumstances that is used to figure out the amount of electricity produced is a cool temperature of around seventy degrees.
When temperatures are much higher, the efficiency of a panel can drop almost twenty three percent. This inefficiency issue is not just in polycrystalline cells, but in all types and so when you're making a choice to install solar panels, whatever the type, temperature is a large concern.
Making the choice to be environmentally and fiscally responsible with the introduction of solar panels into your home is predicated on a number of factors, but overall, some of the best bang for your buck with the same lasting lifespan is found in poly crystalline solar cells.
