Most efficient solar panels FAQs

  • Not always. The LG NeON® 2 Series, Panasonic EverVolt, and Hanwha Q CELLS are all averaged-price solar panels with high efficiency ratings.

  • Currently, the most efficient solar panel on the market is the SunPower A-Series model, which comes in at 22.8% efficiency. However, solar panel innovations are happening very quickly, so there could be an even more efficient solar panel in the near future.

  • Based on how much energy is created from the product, fossil fuels are more efficient than the solar panels currently on the market. Coal and natural gas hover between 30-40 percent efficiency. That said, emissions are a negative byproduct of fossil fuels that outweighs their advantage in efficiency.

  • More efficient solar panels are available for commercial and government entities, such as NASA. However, the materials needed to make residential solar panels more efficient would make them much more expensive.

  • Yes. A high-efficiency solar panel will have a higher output of energy, making your solar panels a better value. Find out more about incentives and rebates you can earn for getting solar panels installed in your state:
