How to Choose an Efficient Solar Panel

Solar panel installation on your home is considered a wise option by most property investors when it comes to saving on your electricity bill. After realizing you can cut off your electricity cost by setting up solar panels, ensure your item is sourced from a credible local distributor with good reviews and ratings. You still need to understand two simple solar energy questions before purchasing a solar panel.

i) What constitutes of an efficient solar cell and solar panel technology

ii) How to choose the top brand of solar panel that operates on your preferred solar cell technology

Efficiency of Solar Panels

This is a term used to refer to the amount of irradiation energy that can be converted to electricity by a solar panel. Efficient solar panels are known to use less square footage per panel to manufacture the desired quantity of solar power.

Crystalline modules have an efficiency rate of 15-20%. They are also good for conservation on space required for your solar power system. Thin film solar panels require large space to install and are not easy to find at your local solar installer dealer. Space is a limited factor in most homes and it is important to find the highest rated output relative to physical size of the solar panel.

Polycrystalline solar panels are considered less space efficient, while monocrystalline have a higher power output. However, since 2014 there has been a massive increase in new polycrystalline solar cell manufacturing and polycrystalline PV module assembly. These factors have led to improved efficiency and lowered cost for the polycrystalline solar panels.

In recent years there has been an increase also in the average wattage of both monocrystalline and polycrystalline solar panels from 250 to 320 watts per panel. At present day it is possible to find polycrystalline solar panels with an average wattage rating that range from 260-300 watts. Monocrystalline solar panels have also been upgraded to an average wattage rating that range from 270-320 watts per panel.
