How Much Solar Power Do I Need for My Camper?
Choose at least 400–500W solar for standard setups. Increase for winter or heavy use. Minimum: 200–300W solar, 100Ah battery: lights, charging, fans, minimal fridge.
For optimal efficiency, aim for at least 300 watts of solar power for larger RV battery systems. This wattage suits a 200Ah lithium battery, enabling quick and effective charging even during cloudy days. Incorporating this additional wattage means you can comfortably use more energy-intensive devices, thus enhancing your overall camping experience.
To properly size your solar panels, you first need to know your RV battery's capacity measured in amp-hours (Ah). This tells you how much energy the battery can store. Don't worry if you're not familiar with battery specifications – here's how to easily find the amp-hour rating:
Boondocking, or camping without hookups, requires a reliable way to keep your batteries charged, and solar panels are an excellent solution. However, selecting the right size solar panel for your RV battery is crucial to ensure you have enough power for your daily needs.
An RV battery at 50% battery will put out between 12.06-12.10 volts, on average. If your voltmeter has a number below this, charge your battery immediately. If you're going to be boondocking a lot, however, it's definitely worth investing in a decent battery monitor or gauge if your RV didn't come with one.
