If you want to know the weight of solar panels in kg, know that the Solar panels weigh around 1-2 kgs per square foot. And, the average weight of a solar panel at home weighs around 40-50 kgs. 

Solar panels are becoming very common day by day. People are shifting their choice to solar to save money, time, and effort at the same time. Hence they have been making investments in solar panels for decades now. 

Before we go deep into the topic, you must know how big solar panels are. This will let you know how much impact it will have on the rooftops.

Commercial panels are much heavier than others in comparison. It weighs up to 50 pounds or even more than that. The weight of solar panels per square foot gives variation depending on the brand. 

More importantly, the weight of the specific solar panels is the total weight of the installation. It impacts the rooftops accordingly. Solar panels are mounted outdoors. Free solar panels are not so easy. It is quite common to install solar panels. 

How Heavy Are Solar Panels? 

A typical solar panel weighs around 1-2 kg per square with mounting structures. It is usually offering acceptable limits of roof loading. 

  • Solar panels are around 40 pounds 
  • Solar panels are approximately 5.4 feet long and 3.75 feet wide
  • Each module typically consists of 60 solar cells
  • When it is to the commercial solar panels the solar cells can turn into 72 solar cells 
  • An extra weight of the solar panels has a weight of 2.7 pounds per square foot and also goes up to 98 cells

Before you understand the dimensions of a solar panel, you must know what size are solar panels and how they should be used to create ways accordingly.

What Makes Solar Panels So Heavy?

When it is about solar panels being heavy, it is something that lets you know the components of a standard solar panel. 

  • Aluminum frame
  • Encapsulation foil 1
  • Encapsulation foil 2
  • Junction box
  • Back sheet
  • Stringed solar cells
  • Tempered cover glass

Solar cells are the primary power to generate components, but they weigh a few hundred grams. In most cases, the weight of the panel is due to the glass as well as the frame of the aluminum.

How To Calculate How Many Solar Panels You Need?

How Much Do Solar Panels Weigh

The amount of power required by the household is the average requirement of power. Once done, it is possible to know how many solar panels I need. A kilowatt is a measurement of power that has a kilowatt hour. 

One must know how to multiply the hourly consumption of energy by the hours of sunlight in your region. Once you get the answer, you can divide it by the wattage of the panel. 

The energy is used to generate electricity or be stored in batteries along with batteries and thermal storage. With this area, you can calculate the area-

Area required for solar panels = Total No. of solar panels x Area of 1 panel
