Rigid, Flexible or Folding Solar Panels?
Rigid panels
Rigid panels are usually the best long-term choice for a roof installation. They tend to be durable, efficient and good value, but they need proper mounting and cable routing.

Flexible panels
Flexible panels are lighter and lower profile, which can suit curved roofs or stealthier setups. They may run hotter and can be harder to replace if bonded directly to the roof.

Folding panels
Folding panels are ideal if you do not want a permanent installation. They can be angled toward the sun, but you need somewhere safe to store them and they are less convenient in bad weather.

Quick Answer

Common Questions
How much solar power does a motorhome need?
Many touring setups start around 100W to 200W. If you run laptops, fans, fridges or stay off-grid for longer, consider 300W to 400W and a suitable leisure battery.
Are flexible solar panels good for campervans?
Flexible panels are light and low profile, but they can run hotter and may not last as long as rigid panels. Rigid panels are often better for permanent roof installations.
Is MPPT better than PWM?
MPPT charge controllers are usually more efficient, especially with larger solar setups or changing light conditions. PWM can be cheaper for small simple systems.
