Unique design idea for solar cell
Full upgrade 5BB solar panel will be your best choice for solar power system

01 Higher Performance Classes

Thanks to 5BB technology, LONGSUN solar modules offer more power per surface,
Resulting in higher yields at lower costs.

02 Temperature Coefficient

Even on hot days, LONGSUN solar modules produce reliable yields and Lose less efficiency than standard solar modules

03 Low-light Behaviour

High yields with low radiation intensity, for example, during sunrise and
Sunset and on cloudy days, but also in autumn and winter when the sun is flat over the horizon.


What's the advantages of solar energy?

  1. Solar energy is a clean and renewable resource.
  2. No pollution, no noise and no effect on ecological balance during use.
  3. High efficiency of energy conversion and long time sustainable use.
  4. Low maintenance and repair costs.
  5. Wide range of applications.(home and outdoor, industrial and commercial)
  6. Low use of environmental requirements.(-40ºC~+85ºC, just need sunshine)
  7. Easy to install and use.


Feature and quality control:

High efficiency solar cells with isotropic etched surface;Low reverse current,high shunting resistance and dependability;Proper handling from incoming inspection through production, outgoing inspection and package;100% checked for reverse current and visual appearance; small light-induced degradation;Calibration by Fraunhofer ISE;PID. Excellent mechanical load resistance: certified to withsand highwind loads(2400Pa) and snow loads(5400Pa); High salt and ammonia resistance certified by CE.
