What is the Largest Capacity/Size Solar Panel Currently?


This question is part of the Super Big Solar Panel FAQ from Solar Mango, where expert answers to over 100 important questions on solar panels are provided.


From sizes at about 250 W only a few years back, some of the largest solar panels today boast Watt Peak of 350 W.

The largest solar panels until even 2 years back used to be less than 300 W, so you can see that the records are tumbling fairly fast.

Many prominent Indian and international suppliers are able to supply solar panels of capacities beyond 300 W today.

As you can see, larger sized solar panels provide significant advantages over smaller solar panels, both in terms of installation and in the context of maintenance.

Why should size matter?

Why would we want large capacity solar panels?

The primary advantages of larger sized modules built at a point-of-use onsite factory are:

Reduced materials and labor installation cost

  • More power per panel means fewer panels in an array
  • Easy installation and lower cable cost
  • Reduced labor cost results from fewer module interconnects
  • Quicker installation period compared to a larger number of conventional module

Reliable and robust design

  • Design to the highest industry standards
  • Bankable and reliable c-Si solar cells, low-iron ARC tempered front glass, sturdy reinforced frame with high mechanical load capability

More power per unit area

  • More power produced in the same unit area with c-Si cells at high efficiency and lower frame “parasitic” area
  • Lower transmission losses — higher energy yield

Less space is required

  • Superior land coverage ratios
