Best Solar Panels, Top Brands Compared

Choosing the best solar panel

There are a wide range of solar options on the market and deciding which one is best for your project can be an overwhelming process. There are over a hundred different solar panel brands on the market, and many are very similar offering a low price but also offering poor warranty, poor quality and subpar energy production. Many customers are driven to the lower price without completely understanding the tradeoff. In this blog we will review how the top panel manufacturers stack up and what makes them better than the other options.

Best solar panels for residential installations

The best solar panels are from some of the most well-known companies, but we will go into details on why these are the best options on the market.

  2. Solaria: Best looking panel with high efficiency ratings
  3. REC: great efficiency ratings and value pricing options
  4. Silfab: Good warranty and good value
  5. Mission: Best panel assembled in the USA
  6. Q Cells: Best panel for budget customers
  7. Canadian Solar: A leader in bifacial technology

The top 3 solar panels receive the top ratings as the best panels due to high efficiency ratings, high product quality, and strong 25-year warranties. SunPower, Solaria and REC offer the best energy production offerings on the market and stand by their products with industry leading warranties. Their panels are made with premium monocrystalline solar cells design with each manufacturers unique specifications making each panel different but the very best options for residential solar. All three panels do come with higher price points than the lower tier panels but in general the security of the longer and better warranty and the higher energy production over time will offset the higher upfront price.
