|What is a solar panel? |
A solar electric panel, often called a PV panel is basically a set of treated silicon cells arranged in a series string that produces electric power when exposed to light. There are three common types of solar panels manufactured. Briefly, they are:
Monocrystalline - made from a single large crystal, cut from ingots. Most efficient, but also the most expensive. Somewhat better in low light conditions (but not as good as some advertising hype would have you believe).
Polycrystalline - basically, cast blocks of silicon which may contain many small crystals. This is probably the most common type right now. Slightly less efficient than single crystal, but once set into a frame with 35 or so other cells, the actual difference in watts per square foot is not much.
For all practical purposes, how the three types work in applications is very similar. What is important when buying panels is to choose the right panel based on how much power you need, how much room you have, and where they will be mounted. They will all do the same thing - make electricity when the sun hits them. Thin film are often less efficient, so will take up more room for the same power, but on the other hand they work better in hot climates due to not losing quite as much at high temperatures.
Sun Smile Solar photovoltaic modules are aesthetically designed for long life and continuous
performance under extreme conditions, for numerous Domestic, industrial and commercial applications.

ELECTRICAL &MECHANICAL FEATURES:
Electrical output of Sun Smile solar modules is classified on the basis of the electrical output produced by the solar modules under light intensity conditions of 1000 W / m , AM1.5 spectral irradiance and at 25 C. The electrical characteristics are typical and subject to production variance, however peak power is the
