Once you’re convinced on the benefits of solar power, you will need to look at the installation of a solar power generator. It’s a good idea to think about the various hardware and materials you will need before the solar cell sale. Choosing a wrong product may cause unstable performance and can result in failure of the system.

Solar cells are an integral part of the system (as this is the actual component that generates electricity for you) and you need to select them with care. You can buy solar cells based on various factors. Here are some handy tips will help you to find the perfect solar cells.

Size and Shape – Usually the solar cell is flat in shape. It is generally few square centimeters. The solar cell is a wafer of silicon that actually produces the current for you. However, you can connect numerous solar cells and create large solar panels. Larger panels are able to deliver much larger outputs; however, they are obviously more expenses. The computation of size and quantity of solar cells is determined on the expected consumption.

Material – Silicon is the most popular and preferred material for the solar cell. Traces of arsenic and boron are added to it for initiating the flow of electrons. It is connected with a metal foil for the power transfer. Many times, commercial photovoltaic panel manufacturers coat the surface of the panel with anti-glare liquid to minimize the losses due to reflection.

Efficiency – A solar cell can deliver up to 20% efficiency. In other words, if you have the availability of 100 watts of solar power, your solar cell can deliver 20 watts of current under the best conditions. However, adding more cells to panel distinctly adds to the output. You can find online tools or calculators to simplify estimation. All you need to do is enter the desired values and the calculator compute parameters for you.

Current and voltage – Depending on the type and material of the cell, each cell can produce power of 0.55 to 0.8 volts. The solar cell is highly sensitive to light, therefore, it delivers more power with exposure to more light. However, there is a benchmark regardless of the light availability; solar cell does not produce more than the rated benchmark capacity.

Buying a solar panel can be easy if you educate yourself first. Also, consider the idea of building your own panels using a DIY solar panel kits and create your own surplus solar panel from parts. Internet or local yellow pages are good sources to find information on where to find a solar cell sales but with a little effort you can simply build your own.
