When installing solar pool heating panels, it is very often the case that roof vents and other obstructions come into play. Placing panels in a way that takes advantage of the available roof space becomes a challenge. There are a several strategies that we use to deal with vents and other obstructions, which may include plumbing vents, attic vents, satellite dishes, electrical service entrances, hips and valleys, skylights, and other roof mounted equipment. Those strategies include:
- Use solar panels with different lengths
- Use half-width panels (we are one of the few dealers that offer a 2′ wide panel)
- Stagger panel heights on the roof
- Use multiple roof faces
- Extend header plumbing to get around obstructions
There are very few roof obstruction challenges that prevent successful solar pool heating installations. It’s always ideal to select a roof with no vents, but we also want to take into consideration the best place for your panels to be in terms of system performance. We take all factors into consideration when designing and installing your solar pool heating system.
These decisions are often left to installers in the field based on conditions found at the time of installation. The precise location of trusses, vents, hip caps, valley flashings, ridge vents, and other roof features are not something that is taken into account when doing design layout and engineering. Smart decisions on exact placement of solar panels and plumbing are the responsibility of the person doing the work, which is why experience, care, and training are critically important for a successful installations on roofs with obstructions and vents when installing solar pool heating panels.
