Within the initial phases of research, you discover that LONGi solar panels are the world’s largest solar module manufacturer by volume (BNEF Q4, 2020). Not only is volume an impressive gauge, LONGi are now proving to be one of the most innovative solar brands and the results are beginning to show in real-world conditions. However, what does all this mean for you? And, how should it affect your solar buying decision?

INSIDE!

Primarily a monocrystalline cell manufacture, est 2000, LONGi Solar clearly has the pick of the bunch when it comes to cell selection for module manufacturing, and the performance is phenomenal for the price point.

Did you know? As more than just another module manufacturer, LONGi supply monocrystalline cells many alternative leading module manufacturers seeking a high purity yet affordable monocrystalline cells to incorporate within competing solar module designs.

Such a practice is quite common amongst many industries. A similar comparison where cell trading amongst manufacturers is common is lithium solar batteries. LG Chem, BYD, Panasonic, Samsung SDI and CATL (to name a few) supply lithium battery cell technology to renowned brands such as TESLA, SENEC, Sungrow, Huawei and more.

Which to avoid?

As with all brands in the Perth Solar Warehouse Ultimate Guide, it’s generally recommended that residential homeowners avoid 72-cell/144+ half-cell sized solar panels and opt for 60-cell/ 120-132 half-cell solar panels. A higher watt-class in the larger panels is often quite appealing for the same price (per/watt), however, these are not more efficient as the module dimension is simply increased.

With no increased efficiency the additional power is achieved simply by adding an additional row of cells. The result, 72-cell solar panels are heavier to accommodate on the intended roof structure possessing 12 additional 6-inch cells (or similar). In-turn adding greater weight to a residential roof structure in a singular area is not ideal for reduced load bearing residential roof types.

Which to consider?

To ensure ease of comparison between brands, 60-cell solar panels are where most residential homeowners should be looking. Considering the above 72-cell LONGi solar panels efficiency, the below similar technology can easily be identified, LR6-60HPH. 

What does this mean? Despite the higher watt class of the 72-cell solar panel, an equal portion of roof surface area is utilised to achieve the desired system capacity with 60-cell solar panels even though there are more panels. Accommodating better weight distribution and ease of design where space limitations/shading exist.
