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.
Use our RV solar calculator above to perform a detailed calculation considering individual power draws, battery and solar panel charging and generation efficiencies, and the number of panels in the array. How many solar panels do I need to run a 30-amp RV? To run a 30-amp RV, you typically need around 300-400 watts of solar power.
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.
To calculate the amount of solar power you need for your RV, you can follow this formula (the process that we use in our calculator above on this page): Determine your daily energy consumption in watt-hours (Wh). Include all the appliances and devices you’ll use, such as lights, refrigerator, TV, etc.
