The best rigid (mounted) solar panels for rv roofs will provide different benefits & drawbacks compared to Rv portable solar panels.
Although rigid solar panels have to be fixed/mounted to your rv roof and are usually permanently fixed there, they are usually more cost effective than a portable panel.
In this short guide, we list & discuss one of the more popular rigid solar panel brands, & model for rv roofs.
Like the flexible solar panels, rigid solar panels are good for charging rv batteries, and other 12 volt batteries.
Let’s have a look at it…

What Is A Rigid Solar Panel For An Rv Roof?
A rigid solar panel is a solar panel setup that is usually permanently mounted or fixed to an rv roof.
They usually consist of a mono-crystalline or polycrystalline solar panel, glass, and an aluminium frame.
NOTE: most people use their framed solar panels mounted to their roof, but SOME people do use them as freestanding units too.
What Types Of Rigid Solar Panels Are There For Rv Roofs?
Rigid solar panels are mostly similar to each other – apart from their maximum output (watts and volts), and accessories you might get with them.
50 and 100 watt panels seem to be the most common sized of the rigid solar panel options.
They differ to portable solar panels mainly in the fact that they are permanently fixed, have a steel/aluminium frame, are heavier & sturdier, and are usually the most cost efficient purely on a price paid compared to power output basis.
What Are Rigid Solar Panels Used For With Rv Roofs?
Rigid solar panels are mounted with brackets and fixed to an Rv roof.
From there, they are connected to a solar controller, and used to charge a re-chargeable lead acid or lithium ion Rv battery.
Solar controllers are used because say a 100 Watt panel operates at 18.9 volts, and the 12 volt battery needs 13.6 volts to fully charge – a controller will limit the volts to what the battery needs so the battery isn’t damaged in the charging process.
Which Rigid Solar Panels To Get For Rv Roof – How To Choose?
It’s really just a matter of checking 3 main things:
1. Check your Rv manufacturer instructions to see whether installing of a solar panel has any impact on the Rv itself (and the battery), or on any existing warranty. If ok, are there any weight restrictions for example?
2. Check the solar panel instructions for installation – does the have the right materials and accessories (brackets and adapters) to install on your Rv?
3. Decide what size (Watts), and how many solar panels you want based on the charging requirements of your Rv battery, and how much space you have available on you Rv roof
Features To Look For In Rigid Solar Panels For Rv Roof
- What is the wattage output of the panel?
- What is the operating voltage output of the panel – is it enough to charge the battery you want to charge or will you need several panels?
- Is the panel frame corrosion proof?
- What weatherproofing and resistance does the panel setup have – wind, rain, snow, heat protection?
- Check what the mounting and fixing practice is for the panel
- Do you need an inverter to use with the panel for any batteries or devices you want to charge?
- Check the solar controller the panel comes with – what are the capabilities and limitations of the controller?
- Check the length and capabilities of any adapters and cables you get – are they long enough and will they be suitable for you charging needs?
- Are you getting a standalone solar panel, or a whole kit with controller, adapters, cables, brackets etc?
- Usually solar companies recommend at least 3 stage battery charging – check how many stages does the solar panels have that you buy?
- How much do the solar panels weigh?
- What size/dimensions are the solar panels – how many can you fit on your rv roof?
- Are there separate warranties for the panels, materials, and accessories (controllers and cables/adapters)? If so, what are they?
- How many purchasing options do you have for the solar panel kit? e.g. can you buy it with mono OR poly crystalline panels, different solar controllers, with and without a kit?
Rigid Solar Panels For Rv Roofs – Accessories
Apart from the solar panel, accessories usually include:
- Z Brackets/Suitable Mounts (for fixing the panel to the rv roof)
- Solar Controller (controls amps and volts between panel to battery)
- Adapters (between the panel and solar controller)
- Tray Cables (between the controller and the battery)
- Additional accessories (optional) may include a solar storage battery, and/or an inverter
