A solar panel array on the roof of your house can reduce the amount of heat that reaches the roof by up to 38%. This means that solar panels can indeed be installed on a roof. The sun produces energy that we can invert into usable electricity, and installing solar panels on the roof is one way to make that happen. Does heat enter your home through the roof? Yes. Solar panels can help reduce the amount of heat that enters your home through the roof.
Solar panels do insulate your roof, but how much cooler your house will be in summer and how much heat loss you can expect in winter nights depends on your home circumstances. Is there external insulation on the roof? Is the space beneath your roof empty attic or living space? Is the space well-ventilated? Is the attic insulated?
Solar panels are typically mounted on metal racks, which are in turn anchored to the roof surface. The installers that Kaster has spoken with are apparently insisting that fasteners attaching the rack-mounting points to the roof go all the way through the sheathing and into a rafter. But how to find them? Mark Nagel suggests a couple of approaches.
Think of your solar panels as a “shade” on your roof. The difference is that this type of shade covers the top of your home 24/7, reducing the roof’s overall surface temperature. A study by the University of California San Diego revealed that solar panels could reduce the roof’s surface temperature by up to 38 per cent.
Much of the heat absorbed by your rooftop solar panels is removed by a convection current, which is air movement in the space between the panels and the roof. As air travels between the solar panels and roof materials, the heat is minimised. This leads to reducing the overall temperature of the roof cooling your home.
For homeowners who already have solar panels installed but need to replace their roof, the process involves a few additional steps: Contact the solar panel installer: They will need to remove the panels and mounting hardware before roof work can begin. Coordination with the solar installer is crucial to ensure minimal downtime for the solar system.

Solar Panels on a Flat Roof: 5 Things to Know
Solar panels on flat roofs may require frequent cleaning. Solar panels on a standard pitched roof tend to clean themselves when precipitation washes down them. In fact, just a slight degree of tilt – 3 to 4 degrees – can help keep solar panels clean when it rains. However, flat panels tend to collect water, dust, and debris, which can reduce electricity generation by …
