Evaluating the Top Solar Panels on the Market

Jessica PirroOctober 10, 20192990

When it comes to getting a solar panel installation a common concern among homeowners is going be, how can they find the best solar panels for their solar-powered systems. For most homeowners, this is what they spend the most time researching. There are hundreds of different brands of solar panels and other solar power equipment on the market at any given point.

The Best Solar Panels for Home Solar Panel Installation

For years there have been a few solar companies that have dominated the solar energy market for years. SunPower, LG, and Panasonic are the solar companies that stand out in terms of the efficiency of a solar panel, competitive pricing, and stellar warranties that the solar companies offer. The solar panels that are coming for these solar companies combine the durability and reliability with premium protection and fair prices, making them the brands that have the best solar panels on the market for residential solar panel installations. In terms of the efficiency of a solar panel, SunPower is leading the solar energy market right now with the efficiency of a solar panel that is close to 23%.

Typically, the best solar panels are going to be made with premium monocrystalline photovoltaic cells. The monocrystalline photovoltaic cells are going to be made with a single crystal of silicon instead of many silicon fragments that are molded together through extensive heat, which goes the same for polycrystalline photovoltaic cells. This means that the photovoltaic cells are going to be more efficient at converting the sunlight to solar electricity, the solar panels also have the sleek black appearance that makes them look very aesthetically pleasing. But, as expected the all-black premium solar panels have (especially from these solar companies) have higher prices.

Solar Companies Ranked By The Efficiency of a Solar Panel

The efficiency of a solar panel is a measure of how well it converts sunlight into solar electricity. It is based only on the maximum efficiency of a solar panel.

Best Solar Panels in Terms of Temperature Coefficient

Another way to determine the best solar panels on the market is by looking at the temperature coefficient. The temperature coefficient is a measure of how much or how little the solar panels, solar energy production drops in the hot temperatures.

Best Solar Panels Ranked by Warranty

There’s yet another way to determine the top solar panels on the market, and that the by the solar panels warranty (or the equipment warranty) protects against the equipment failure due to the environmental factors or manufacturing defects.

- LG (25 Years)

- Panasonic (25 Years)

- Silfab (25 Years)

- Solaria (25 Years)

- Sun Power (25 Years)

As it was listed above, all of the solar companies that have the best materials warranty all have the same length of the warranty, setting the bar for the rest of the solar companies. Most other solar companies have a 10-year materials warranty.
