Solar panels do not provide traditional insulation like foam or fiberglass that prevents heat flow through a roof structure. However, they have an indirect impact on 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?
As mentioned, solar panels generate energy by harnessing sunlight. However, their efficiency can be affected by extreme temperatures. This is where insulation comes into the picture: Temperature regulation: Insulation helps stabilise indoor temperatures, reducing the strain on heating and cooling systems.
Roof with solar panels. There are many reasons to get excited about this building. Folded plate structures are efficient in their use of materials and can cover very long spans, being basically very deep beams on a tilt, leaning against other very deep beams.
In summer, solar panels can lower a roof’s temperature by 5°F (3°C), and in winter, they can also slightly prevent a loss of heat through your roof at night. The main temperature benefit from solar panels is in the cooling department. In this article, we’ll discuss how solar panels act as a roof insulator and how much of an effect they really have.
This drawing shows a roof assembly with exterior rigid foam, which has been enough to discourage solar installers from attaching panels. Illustration courtesy Kaster. Kaster has retrofitted his Bronx, New York, home to Passive House standards, a project that included the installation of 6 in. of rigid foam insulation on top of his roof deck.
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.
