High Efficiency Output - Best Shingled Solar Panel - SGD Series

Shingled cell technology for shingled solar panels, which uses overlapping thin cell strips assembled either horizontally or vertically across the panel, provides a high level of efficiency and productivity.

Shingled cells are made by laser cutting ordinary full-size, high-quality monocrystalline PERC cells into strips (typically 5 or 6). Depending on the panel size, the narrow strips are assembled into long strings of 34 to 40 cells. They are connected using an electrically conductive adhesive (ECA) for electrical conductivity and flexibility.

Shingled solar panels offer more yield per square meter. shingled solar panels are also less susceptible to hot spots and are cost-effective.

How do shingled solar panels compare to conventional panels?

Shingled solar panel vs. solar panels

Solar Panels

Traditional solar panels use different numbers of solar cells depending on the desired output of the panel. The solar cells are distributed throughout the panel with space between the cells. They are electrically connected by a high-temperature welding process using copper bus bars.

The more copper busbars used, the lower the resistance losses and therefore the more efficient the electrical connection. However, more busbars covering the cells means fewer solar cells are exposed to sunlight, which reduces the output of the cells.

Shingled Solar Panel

Since the shingled cells of a shingled solar panel are connected differently than conventional solar panels, busbars are not required and the cells can be connected so that there is no gap between the cells.

The wiring of shingled solar panels can also be different from conventional solar panels. Typically, the solar cells in a conventional solar panel are wired in a series of strings, whereas the solar cells in shingled solar panels can be wired in a parallel configuration.

Advantages of shingled solar panel

Essentially, the three key benefits of shingled solar panel design are generating more power, improving reliability, and aesthetics.

1- Higher power per square meter – shingled solar panels do not require a bus bar across the top of the cell, so more of the solar cell is exposed to the sun, and therefore the solar panel area can produce more energy.

2- Increased Shade Resistance – Conventional solar panels have individual cells connected in series, so when a portion of the solar panel is shaded, this can have a significant impact on the power output level. shingled solar panels significantly reduce the losses caused by shading.

3 – Better Mechanical Properties – Static and dynamic load tests have shown that shingled solar panels are more resistant to failures due to external forces applied to the solar panel than conventional solar panels. In addition, the conductive adhesive used on shingled cells helps to minimize internal stresses due to thermal expansion.

4 – Unique Visual Appearance – Shingled solar panels have no visible circuitry, which gives them a clean and simple appearance that provides superior curb appeal.
