Use this guide to estimate your power needs, understand watts, watt-hours and amp-hours, and narrow down the right solar components for caravan, motorhome or off-grid use.
Start the Guide
Watts show how much power a device uses at one moment, helping you compare loads and plan what your setup must run.
Watt-hours show how much energy you have over time, so you can estimate how long your batteries can keep things running.
Amp-hours describe battery capacity at a given voltage, making it easier to compare storage and choose a battery bank that fits your needs.

Start with your daily power use, how often you travel, and which appliances matter most. That gives you a practical picture of how much generation and storage to look for before comparing products.
Compare panel size, available roof or ground space, and the amount of sunlight you typically expect. The main job is to match your charging goals with the space and conditions you actually have.
Look at how much storage you need for nights or cloudy days, plus the system size you are planning around. A battery choice should fit your routine, not just the biggest number on the page.
Check what your system needs to manage charging, convert power for appliances, and connect everything safely. Gather the details of your current setup so you can choose the right supporting parts without guessing.
List the appliances you run, how long you use them, and the watts they draw. Turning that into watt-hours gives you a simple daily total to size around.
Measure roof area, battery compartment space, and where cables can travel safely. The right setup starts with what your vehicle can physically fit and support.
Compare solar panels, lithium batteries, controllers, inverters, and accessories against your usage goals. Think about charging habits, travel style, and how much independence you want from shore power.
Before you buy, review the whole system together: energy use, storage, charging, mounting space, and future expansion. A final checklist helps you choose with confidence and leave room for links later.
