About Spectra PERC-S Solar Panels?

The Spectra PERC-S solar panels have a rigid aluminium frame and sleek black cells that allow the panels to stand out from others in the market; its unique cell design and durable build allow the panel to be highly effective in any application, whether it’s at an On-Grid or Off-Grid application.

The Spectra PERC-S solar panel range all have identical frame lengths making it easy to combine panel sizes to accommodate the space available.

Why Choose Spectra PERC-S?

PERC (Passivated Emiter Rear Cell) Technology.

Monocrystalline Solar Cells

Shingled Cell Module Design (Shade Resistant Technology).

High light absorbency especially in low light.

Highly reliable internal electrical connections.

No reflective metal lines on the cells.

Increased efficiency.

Identical frame lengths for combining different ratings to accommodate available space.

Reinforced Black Aluminium Frame

Safety Glass

Spectra PERC-S Unique Cell Design

Unlike conventional panels the Spectra PERC-S range uses intelligent PERC (Passivated Emiter Rear Cell) technology and has a Shingled Cell Module Design to achieve 15% higher energy efficiency.

PERC (Passivated Emiter Rear Cell) Technology allows the cell to absorb more light than other conventional cells and improves the modules performance during low light conditions.

Shingled Cell Module Design is the way the sliced cells of the panel are connected. The Spectra PERC-S range use conductive glue that connects each each slice of cell.

The two bypass diodes on both sides of the module and the cell connection being in both parallel and in serial limit the Hot Spot risks under partially shield exposure conditions .
