The Solar Panel Efficiency is Growing

Solar energy today is becoming much more common than it was a few years ago. It has zero emissions, operates silently and requires little maintenance. Moreover, solar panels have been significantly improved in recent years.

Roger Huber, CEO of Swiss Solar, a solar panel company from Summerland, has been working in the industry for more than 30 years. He says that the panels available today are much more efficient and less expensive than they were in the past. For instance, the modern panels are 30 to 40 percent more efficient than solar panels five years ago.

Various solar panel manufacturers have made a number of significant achievements aimed at improving solar cell efficiency. According to, 23,5 percent is the current solar panel efficiency record set by SunPower panel manufacturer.

Swiss and American scientists have worked on Perovskite solar cells to improve cost per watt in the past two years. The result of their successful research is going to be a solar panel that can generate 20+ percent energy more than other solar panels do today, being offered at affordable price on the market.

In May 2018, the researchers of the Massachusetts Institute of Technology announced an innovative concept that can double solar cell efficiency. This technology captures and utilizes the thermal energy usually emitted by solar panels. That means reducing the cost of solar energy even further.
