Caravan Solar Installation Practical Off-Grid Power for NZ Caravan Travel
Custom solar systems for caravans, professionally designed and installed at our Christchurch workshop to deliver reliable off-grid power for New Zealand conditions.
Based in Christchurch, RV Solutions installs caravan solar systems designed for how Kiwis actually travel— from weekend getaways to extended off-grid touring around New Zealand. We'll help you choose the right balance of panels, charging and battery support for reliable power without over-speccing.

A good caravan solar system isn't just "more watts". It's the right balance of solar panels, solar controller, battery capacity and safe installation so you can run the essentials—fridge, lights, device charging and water pump—without stressing about flat batteries.
What we include in a caravan solar installation
- System design for your caravan (roof layout, shading, usage and battery type)
- Quality components matched to your needs (panels, controller/regulator, cabling, protection)
- Neat, weatherproof roof fitting with tidy cable entry and secure mounting
- Safe wiring and testing to protect your caravan's 12V system
- Practical handover so you know what your system can run and how to get the best from it
Choose the right system size (without guessing)
If you mainly do weekends with powered sites, a smaller setup can be perfect. If you camp off-grid for longer, you'll benefit from more solar and (often) more battery capacity. Use our RV Solar Calculator to estimate the right size based on your appliances and travel style.
Want stronger performance? Batteries and inverters matter
Solar works best when your storage and 230V setup match your goals. If you want to run higher-draw items (like coffee machines, microwaves, induction cooktops or medical devices), you may also need an inverter and battery upgrade. We can help with RV battery upgrades and RV inverter installation.

How many watts of solar do I need on my caravan?
It depends on how long you stay off-grid, how much sun you'll typically get, and what you're running. As a rough guide, light users can suit smaller systems, while frequent off-grid travel benefits from larger solar and adequate battery storage. The quickest way to size it is our Solar Calculator.
Can you install solar on a caravan with limited roof space?
Yes. Roof layout is common challenge—vents, hatches and shading all reduce usable area. We'll design around what's available, and recommend the best panel placement and controller setup for your caravan.
Will solar keep my fridge running?
In most cases, yes—provided the system is sized correctly and your batteries are in good condition. Fridges run 24/7, so battery capacity (and battery health) is just as important as panel size.
Can you upgrade an existing caravan solar setup?
Definitely. If you already have solar but it's not keeping up, we can expand or optimise your system. See Expand Existing RV & Caravan Solar Systems.
Do you install in Christchurch only?
Our installations are completed at our Christchurch workshop. If you're travelling through, book ahead and we'll schedule your install time.
