Technical FAQs 4

Can a residential roof support a solar panel system?

Most residential roofs can support solar panel systems, but calculating your roof’s load capacity is a crucial step before installation begins. Understanding your roof’s structural limitations isn’t just about safety—it’s also required for permits and can prevent costly structural damage down the road.

How to calculate solar panel roof load?

How to Calculate the Solar Panel Roof Load? To calculate the solar panel roof load, you’ll want to dive into two main areas: point load and distributed load. The point load represents the pressure applied to specific points where the solar panels and their mounting hardware attach to the roof.

Should I install solar panels on my roof?

Installing solar panels on your roof is a smart investment, but first you need to ensure your home can handle the additional weight. Most residential roofs can support solar panel systems, but calculating your roof’s load capacity is a crucial step before installation begins.

How much weight does a solar panel add to a roof?

New solar panels by brands like Tesla are fairly thin and lightweight. In most cases, a solar panel installation will now only increase the load on a roof by somewhere around 2 to 4 pounds per square foot. The number of solar panels you install generally makes no difference as all that matters is the additional weight per square foot.
