When it comes to solar panels for campervans, there are two construction types you should consider: rigid solar panels and semi-flexible solar panels. As a premium vehicle upfitter, Waypoint has used both types of panels as each have their advantages depending on the use case. Let's explore:
Rigid Solar Panels:
Example: Zamp
Construction: Rigid solar panels consist of a solid backing material, typically aluminum or fiberglass, and are covered with tempered glass. They are solid and inflexible in nature.
Efficiency: Rigid panels generally have higher efficiency due to the use of monocrystalline or polycrystalline solar cells, which convert sunlight into electricity more effectively.
Durability: The tempered glass construction protects solar cells from most physical damage, moisture, and UV radiation experienced by life on the roof of a van.
Weight: Rigid panels are heavier compared to semi-flexible panels due to the solid backing and glass cover, making them more challenging to install or mount on curved surfaces.
Installation: Rigid panels require a generally flat surface for installation. They are typically bolted or mounted securely to the roof or surface of the campervan using brackets or adhesive. Due to the fact that there is an air gap of some kind between the panel and the surface of the vehicle or trailer, this allows for the panel to cool in extreme heat and will also keep sun off of your roof.
Aesthetics: Rigid panels may have a bulkier appearance when installed due to their thicker construction and framework.
Semi-Flexible Solar Panels:
Example: Sunflare
Construction: Semi-flexible solar panels are constructed using thin-film solar cells embedded in a flexible polymer material, such as ETFE or PET. They have a lightweight and bendable design. Due to the fact that they are generally mounted directly to a roof or flat surface, they do not have an air gap between the panels and the surface which can lead to decreased performance in extreme heat.
Efficiency: Thin-film solar cells used in semi-flexible panels are generally less efficient compared to crystalline silicon cells used in rigid panels. They produce less electricity per square foot of surface area.
Durability: Although flexible panels are designed to be durable, they are more prone to physical damage from impacts or punctures compared to rigid panels with tempered glass protection.
Weight: Semi-flexible panels are considerably lighter than rigid panels, which can be advantageous for weight-conscious campervan owners.
Installation: These panels are flexible to some degree, allowing them to conform to curved surfaces, such as the roof of a campervan, without requiring additional mounting brackets or special installation.
Aesthetics: Due to their flexibility and slim profile, semi-flexible panels have a sleeker and less intrusive appearance once installed.
Ultimately, the choice between rigid and semi-flexible solar panels for your campervan depends on your specific requirements, installation preferences, weight considerations, and the available surface area for solar panel placement. Consider the pros and cons of each type and select the option that best aligns with your needs and constraints.
