Photovoltaic panel size comparison

What are the different sizes of solar panels?

There are three main sizes of solar panels to know: 60-cell, 72-cell, and 96-cell. For commercial and residential solar panels, the 60-cell and 72-cell solar panels size are most commonly used as the 96-cell measures 17.5 square feet – which can make for a challenging fit on your roof.

How big are residential solar panels?

Most residential solar panels are 1.7m tall x 1.0m wide (or 1.7 m2), with a maximum power output of around 330W. Solar panels also come with 72 solar cells, which are larger to accommodate the additional cells. They are around 30% larger than residential solar panels, measuring approximately 2.1m tall x 1.1m wide (or 2.3 m2).

How big are commercial solar panels?

On the other hand, commercial solar panels typically feature 72 cells, with dimensions of approximately 3.25 feet by 6.5 feet. These panels cover an area of 21.13 square feet and weigh about 50 pounds. These larger panels are often chosen for more extensive solar projects.

How much do solar panels weigh on a roof?

It is also important to consider the weight of installing solar panels on your rooftop. On average, mounting equipment and solar panels weigh two to four pounds per square foot. “In terms of weight, it has little impact on your roof, as it’s built to support much heavier infrastructure.

What size solar panels do I Need?

For example, 6.6kW systems are very common for residential solar, so one of these systems will need 18 x 350W panels and 13 x 500W panels. Greater wattage rating does not necessarily mean that the panel is better or newer than a lower rating.

What is the difference between a 60-cell and 72-cell solar panel?

You’ll typically find that 60-cell solar panels have output ratings between 350 and 400 watts and efficiency ratings between 17% and 19%. 72-cell panels, on the other hand, are usually arranged in a 6-cell by 12-cell grid.
