Which to avoid?

As with all other brands in the Perth Solar Warehouse Ultimate Guide, residential homeowners should avoid 72-cell sized solar panels and opt for 60-cell solar panels. Yes, the higher watt-class is appealing for the same price (per/watt), however, these are not more innovative.

No more efficient, 72-cell solar panels are heavier to accommodate 12 additional 6-inch cells (or similar). Adding greater weight to your roof structure in a singular area is not ideal for many residential roof types.

Which to consider?

To ensure ease of comparison between brands 60-cell solar panels are where every residential homeowner should be looking. Considering the above 72-cell LONGi solar panels efficiency the below similar technology can easily be identified, LR6-60HPH 300-320M. 

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 formating designs where space limitations/shading exist.
