Choosing the right solar compare is one of the most important decisions you’ll make for your renewable energy system. You want to ensure that the panels you choose meet your energy needs, fit on your roof and look good in your home. There are many factors to consider including the efficiency level and wattage of the panel, as well as the degradation rate and temperature coefficient. Choosing the wrong solar panels could significantly cut into your energy savings.
While a slightly higher efficiency rating doesn’t necessarily indicate better quality, manufacturers must also have the right manufacturing process, real world performance and reliability, manufacturer support and warranty conditions to be considered among the best. Our rankings take into account all of this information and more.
