Finding the right size of solar panels for your home is essential to make the most out of your solar project. In this blog, we’ll see if you should go with big solar panels or skip them.

Should you go with 500-watt solar panels?

144 half-cut monocrystalline cells are often used to create 500-watt solar panels. 

A single 500 W panel typically has a footprint of roughly 27.5 square feet (7.40 feet x 3.72 feet). 

Each 500 W panel weighs roughly 71.2 lbs (32.3 kg) in weight. 

Due to their size and weight, 500 W panels are more suitable for commercial applications. 

To understand better, let’s examine the dimensions and number of solar cells in residential and commercial panels. As examples, we’ll utilize two solar modules from the LONGi company. 

Residential solar panels are 60 solar cells or, more recently, 120 half-cut cells assembled into solar modules. These panels typically weigh around 43 lbs. and size about 5.76 feet by 3.41 feet—for instance, LONGi Hi-MO 4m. 

Traditionally manufactured with 72 cells, commercial solar panels are more significant modules currently made with 144 half-cut cells. The dimensions of these panels are approximately 7.40 feet by 3.72 feet, giving them a more substantial footprint—for instance, LONGi Hi-MO 5m. 

What is solar panel wattage ideal for your house? 

What size solar panel should you choose if 500-watt panels aren’t appropriate for your needs? 

A 350–400 W solar panel will be the most often used option for residential installations in 2022. This is because this range provides the finest balance of the three critical characteristics of solar panels: size, cost, and efficiency. 

Solar firms often have a variety of panel types in store and almost always carry at least one 350–400 W panel.
