Solar panels are a packaged, connected assembly of photovoltaic cells.

  • They are typically used in high reliability applications.
  • They too experience a significant reduction in output at elevated temperatures (>50deg C), although the effect is not as large as for polycrystalline panels.
  • Monocrystalline solar panels are one the most efficient commercially viable photovoltaic solar collectors.
  • Expensive to make.
  • More power per square foot.
  • Extremely fragile.
  • Identifieable by its signature light or dark blue colour, but not uniformly so: some patches are lighter than others, and the corners of cells are usually missing as a result of the production process and the ph.ysical nature of monocrystalline silicon
  • Efficiency up to 20%.

  • Panels made from polycrystalline cells are the most common and cheapest.
  • Output is significantly reduced in high temperatures.
  • 12% to 12.5% efficiency.

  • Their output does not decrease in elevated temperatures.
  • Their conversion efficiency of sunlight to electricity is about half that of polycrystalline or monocrystalline panels, so you will need a much larger surface area for the same power out.
  • Can be rolled up

  • Amorphous are shade tolerant.
  • Mono or Poly with bypass diodes handle partial shade better.
