How to make solar panels more efficient

high efficiency solar panel manufacturing

Not all solar panels are created equal. EnergySage uses a classification system for solar panels based on performance, quality, durability and warranty to help solar shoppers compare the quality of all of their options. A solar panel’s efficiency (how effective a panel is at converting sunlight into electricity) is a key factor determining solar panel quality, and manufacturers are constantly improving their processes to create higher-efficiency solar panels.

What are the most efficient solar panels on the market?

For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.

As the race for the most efficient solar panel continues, it’s important to understand how more efficient panels could mean much bigger solar savings for the everyday consumer.

In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.
