Navigating the Sizing of a Camper Van Solar System: A Guide to Calculate the Energy You Need

Harnessing solar power for your camper van involves a strategic process to ensure you generate sufficient energy to power your adventures. Understanding your gadget consumption and portable solar panel capabilities aids in procuring the right equipment, ensuring an efficient and well-fitted setup.

Step 1: Calculating Power Consumption

Begin by assessing your gadgets’ power consumption to gauge your solar energy needs. Utilize your leisure battery’s Ah rating to determine the daily power usage. For instance, if a 200Ah battery fuels your devices for two days, your calculation would be 200 / 2 = 100Ah per day.

Take into account the power draw of all electrical devices to estimate your camper’s power requirements accurately.

Step 2: Assessing Solar Energy Requirement

Once you’ve gauged your power needs, focus on determining the solar panel type and size required. A solar panel’s wattage directly impacts its charging capacity for your battery bank. Calculate the usable capacity of your battery bank in watt-hours (Wh). For example, considering an 80% discharge limit for a 200Ah LFP battery, the functional capacity would be 200Ah * 80% = 160Ah.

Convert these amp-hours (Ah) to watt-hours (Wh) by multiplying with the battery voltage: 160Ah x 12V = 1920Wh.

Account for the sun’s angle, especially since campervan solar panels are typically roof-mounted. While this may marginally affect efficiency in summer, it significantly impacts performance during winter.
