A solar cell is an alternative energy that utilizes photovoltaic effect to convert the light energy originating from sunlight into electrical energy. They are readily available in many shapes and sizes on which their voltage specifications would depend. Voltage specification is proportional to the size of the solar cell and thus when the voltage specification is higher, the size of the cell need to be equally large. Solar cells are available in various versions, which could work with visible light to infrared light and depending upon the complexity of a solar cell the price differs. You'll find solar cells for sale at various shops across the globe and also on the internet at websites of various leading companies.
Normally we have to have substantially high voltage to run a specific product while a single solar cell is unable to deliver the results and so , we generally install a number of solar cells. Thereby making a solar panel to deliver the required potential difference to suit our requirements. All solar panels gets built from solar cells and they are the basic building blocks of a solar panel.

You could usually find solar cells for sale either over the internet or at stores and it will cost you approximately five dollars per watt. An average house that requires 3000 watts of capacity will have to invest about US$ 15000 to purchase solar cells. Though the initial investment is very high, this substantially cuts down the overall expense that you would have spend on electricity bills considering the fact that these solar cell once fixed, do not require any maintenance for the next 20 years. It provides an environmentally friendly alternative to electric power in your place.
