Solar Silicon Cells up to 19.5% efficiency.

Since the 1970s the National Renewable Energy Lab (NREL) has cataloged over 20 differerent type of solar cell technology. Below are some solar cell technologies:

thin silicon solar wafers 125mm x 125mm

  • traditional crystalline silicon cells
  • thin-film cells
  • single-junction cells
  • multi-junction cells
  • quantum dot cells
  • solar concentrators

These above tech have various efficiencies.Our monocrystalline solar cells have efficiencies of up to 19.5%.

What does solar efficiency rating measures the percentage of sunlight photons hitting the solar cell for a given space. Higher efficiency means that less surface area is required to to generate electricity. So a small rooftop will want to use higher efficiency panels to compensate for smaller surface area.
