Solar Module Types

We only purchase High Quality Solar modules from companies that manufacture there own solar Cells!

FYI: Solar Modules are made up from multiple "Solar Cells", where a 60cell Panel, is made up from 60 individual Cells etc., cells vary in size depending on the Module type.

There are Modules with 60, 72, 96, 120 and 144 cells, the latest panels are Half-cell Module Technology, designed to greatly increase energy harvesting in partly shaded modules, these have 120 or 140 cells per Module, Shingled solar cells are the latest promising design technology.

The most robust solar modules have 12 Wire Buss Bars (12BB), and Half Cut Panel modules are designed where panel shading is an issue.  Solar modules with 12BB technology (shown below) improves the long term reliability of modules used in harsh windy & shady environment.

In 2020 the latest advancement in solar cell technology is OVERLAP TECHNOLOGY, called "Shingled cells (Overlapping cells) are an emerging technology which uses overlapping thin cell strips which can be assembled either horizontally or vertically across the panel. Shingled cell are made by laser cutting a normal full size cell in to 5 or 6 strips and layering them in a shingle configuration using rear side connection adhesive. The slight overlap of each cell strip hides a single bus-bar which interconnects the cell strips. This unique design covers more of the panel surface area as it doesn't require front side busbar connections that partially shade the cell, thus increasing the panel efficiency much like IBC (Interdigitated Back Contact) cells.

Another benefit is that the long shingled cells are usually connected in parallel which greatly reduces the effects of shading with each long cell effectively working independently. Also shingled cells are relatively cheap to manufacture so they can be a very cost effective high performance option, especially if partial shading is an issue."

Leading edge High quality Solar modules all come with 10year Warranty and performance Guarantee now vary between 25~30 years.
