Are you thinking of using solar energy to make your life greener and protect the environment? When selecting modules for your solar energy system, there are a number of factors to consider.
The price of a solar panel is determined in part by size (in watts), physical size, brand, durability/longevity (or warranty period), and any certifications the solar panel may have.
Selecting solar panels based solely on price is not appropriate because they may not be suitable for the area you are planning to install them in, may not have the certificates required to qualify for government rebates, or may not have them for the required economic payments of resulting energy guarantee features.

The durability or longevity of solar panels is important for several reasons. First, if a solar panel only has a 10 year warranty and is used in a grid connection system, you would expect the solar panel to produce enough energy to pay for itself in 10 years.
Solar Collector Efficiency
There is much debate about the effectiveness of solar panels, ie. how effectively the panels convert sunlight into electricity; But the most important point to remember is that a 100 watt solar panel produces 100 watts; regardless of the estimated performance.
Regardless of the technology currently used, full shade solar panels will provide only a fraction of their rated output; As such, the advertised "shadow-hold" feature can be somewhat misleading.
