But ten years later solar panel producers have made substantial strides in the manufacturing process. The energy output from the sun has increased significantly during the 20th century according to a new study. Design and implementation over the last ten years solar panels have seen many improvements in their design and implementation to reduce costs and improve the installation process.

While innovators haven t been able to reach the coveted 29 efficiency there have been a lot of great developments in years past. An exceptionally positive development in solar energy in the last decade is the overall decrease in solar panel costs. Changes in solar panel cost over time can be explained by swanson s law which states that the price of solar pv modules decreases by about 20 percent for every doubling in global solar capacity the law is named after richard swanson founder of high. Modern panels and rack materials.

Modern panels are lighter and more compact than they were 20 years ago mounting systems are easier to use and installers now have far more experience. The trouble is the initial cost of installation. Many studies have attempted to determine whether there is an upward trend in the.
