What is the Best Solar Panel for You?

You can evaluate solar panels on a few main parameters: production, durability and manufacturer quality.

The amount of electricity a given solar panel can produce will produce is dependent on several factors, including the power rating, power tolerance, efficiency and temperature coefficient. Taken together, these factors will tell you how much power your panel will be able to produce.

You’ll also want to look at indicators of panel manufacturer quality. Start with the warranties and assurances that the manufacturer offers on their equipment. Like all things, solar panels degrade and become less efficient over time. Many manufacturers will guarantee that the power production of their panels doesn’t fall below a certain threshold over twenty-five years. In addition, many panel manufacturers have a materials warranty in case the panels simply fail.

Most solar panels are very durable, but if you live in an area that has heavy snow or high wind, you should also be sure that the panels you install are designed to withstand the conditions in your area. Look for panels that meet the IEC 61215, a reliability standard established by the International Electrotechnical Commission (IEC). IEC 61215 uses an accelerated outdoor stress test for panels to ensure their durability.

When you evaluate panels on production, durability and manufacturer quality you’ll find they break down into categories. EnergySage’s ranking system, which takes all of these factors into account, sorts panels into three groups: premium, standard, and economy.

While some homeowners may choose to invest in the highest quality, most efficient “premium” panels, remember that those will come with a higher price tag. Going solar is a lot like buying a car: not everyone needs a Porsche! Conversely, if you want to save by buying cheap solar panels, your system may produce less electricity over its lifetime, reducing your overall savings. Only you know what is best for your home.
