Learn more about the achievements of the PV Fleet Performance Data Initiative, the basics of PV technology, and the solar office's PV research. The efficiency of your solar panels is important in two scenarios:The more efficient the panels are, the fewer you need to meet all or most of your home’s energy demand. This often means higher upfront cost, but greater energy savings down the line.If your roof is small and you have little space for a ground mount solar array, then fewer, more efficient panels is what will serve you best.

It''s important to choose efficient solar panels, but you don''t always need to choose the most efficient model. Here are some scenarios when selecting the most efficient panels makes sense: 1. You want to maximize your solar production. You may want your system to produce as much electricity as possible.
How High-Efficiency Solar Panels Save Space. As the efficiency of photovoltaic cells continues to increase, solar panels will be capable of generating more watts per square foot. A 400W solar panel that measures 80" x 40" is producing 18W per sf. With an efficiency increase of 33%, it would be possible to generate 24W per sf.
High-efficiency solar panels can reach as much as nearly 23%. The power rating of a standard-sized panel has likewise increased from 250W to 370W.
