Solar Panels

With solid supply lines (we ship a 40ft container from China every 10 to 14 days), Solar SG can supply any solar panel size from any preferred manufacturer.

Unless otherwise specified, we typically offer two standard panel sizes: medium (1.1m x 1.7m) and large (1.1m x 2.3m). The medium panels have an efficiency of 22.3% and a capacity of around 435W. The large panels have an efficiency of around 22.9% and a capacity of around 590W. We usually recommend the large panels due to their higher efficiency. For smaller rooftops, it may be more feasible to choose medium-sized panels as they can fit more easily into smaller corners and sections of the rooftop.

We only use monocrystalline half-cell solar panels. Half-cell panels feature solar cells that are precisely halved, a design refinement that maintains panel output while significantly decreasing electrical resistance within each cell. Widely adopted in contemporary solar panel models, this technology represents a standard advancement in the industry. Half-cut solar cells offer superior performance and durability compared to full-cell counterparts. They can elevate panel efficiencies by several percentage points, ensuring optimized energy production. Moreover, their smaller size enhances physical robustness, making them more resistant to breakage. With a unique wiring arrangement, half-cut cells exhibit greater tolerance to shading conditions.
