What Size Solar Panel for Campervan

campervan solar panels

Opting for the right campervan solar panel size for a campervan depends on your energy requirements and available space. A popular choice for trailer vans is a 100 to 200 Watt solar panel, which can produce sufficient power to charge bias and run appliances like lights and a small fridge. It's essential to evaluate your power consumption and roof space to determine the ideal solar panel size for your motorhome to ensure you have sufficient energy for your adventures. With this guide, we will learn everything about solar panels for your campervan or motorhome. Let’s Go!

1. Why do You Need Solar Panels for Your Campervan/Motorhome?

Solar panels for campervans or motorhomes offer you with several benefits:

  • Energy Independence: Solar panels give a renewable and independent source of power, reducing your reliance on traditional electricity sources and allowing you to go out of the grid for longer ages.
  • Cost Savings: Once installed, solar panels can significantly reduce energy costs, as they harness the sun for free and convert it into usable electricity.
  • Generate Revenue: Earn extra revenue from your motorhome by renting it to others who wish to have an outing with their friends or family for a day or more. 
  • Environmentally Friendly: Solar energy is a natural and sustainable source of power, which reduces your carbon footprints and minimizes environmental impact.
  • Quiet and Low conservation: Solar panels are silent and bear minimum conservation, making them a hassle-free energy result for your motorhome.
  • Extended Adventures: With solar panels, you can extend your passages without fussing about running out of power. They're particularly useful for the out-grid and boondocking adventures.

2. How to Choose the Right Size of Solar Panels for Campervan?

Generally, solar panels come in the range of 50W, 100W, or 200W. However, the size and number of panels required depends upon your power requirements, leisure battery, and solar panel type. Opting for the right size of solar panels for your campervan involves several crucial ways:

2.1 Calculate Your Energy Need

Determine your daily energy consumption by listing all the appliances and biases you plan to use in your campervan. Consider factors like the number of hours each device will run and their power conditions.  

2.2 Check Your Leisure Battery

Ensure your campervan's rest battery is in good condition and has enough capacity to store the energy generated by the solar panels. However, it may only be suitable to store the redundant energy efficiently if your battery is bigger. Also, you should know the amp-hour for your leisure battery. For instance, if 110Ah battery is powering up the appliances you need for 5 days, the leisure battery calculation would be 110Ah/5 = 22Ah per day.

2.3 Choose Type of Solar Panels

You should choose from the different types of solar panels, including monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are more effective but expensive, while thin-film panels are less effective but more affordable. Thin-film solar panels have less life than monocrystalline solar panels. However, you should consider your budget and space constraints when choosing the suitable type.

3. How Much Electricity does A Solar Panel Produce?

The quantum of electricity a solar panel can produce in the UK depends on a few factors, including position, panel type, and rainfall conditions. On an average, a 100 Watt solar panel can produce between 280-350 kWh of electricity per time in the UK.

To estimate the electricity product of a solar panel in the UK, you can use this general rule:

  • Multiply the panel's wattage (like, 100 Watts) by the number of peak sun hours in your area. In the UK, this varies by region but can be roughly estimated at 3-4 peak sun hours per day.
  • So, for a 100 Watt panel with 3-4 peak sun hours, you can anticipate producing roughly 300-400 Watt hours (0.3-0.4 kWh) per day.

Keep in mind that solar panel effectiveness can vary and factual performance by shadowing panel angle and other conditions. It's recommended to consult with a solar expert or use a solar calculator to get a more accurate estimate for your specific setup.

5. FAQs about What Size Solar Panel for Campervan

5.1 Is 100W solar panel enough for campervan?

Not really, a 100W solar panel may not be enough for a full-fledged campervan. A single 100W solar panel can only help to charge your smartphones or run less energy-consuming appliances. According to the report, a 100W solar panel can produce up to 30 Ah, which is not sufficient to give power to a whole campervan.

5.2 Is 200W solar panel enough for campervan?

A 200W solar panel might be enough for your campervan. With this solar panel, you can power a laptop, a TV for 2 hours, microwave for 1 hour, and a lightbulb for at least 12 hours. However, 200W solar panel is enough or not depends on the power needs of your campervan.

5.3 What type of solar panel is best for campervan?

There are a number of solar panel types available in the market, but choosing the right one for your campervan is essential. The best solar panel would be either monocrystalline or thin-film. The monocrystalline solar panels are proven to be more efficient and less in size. Whereas thin-film panels are less expensive and less efficient than monocrystalline solar panels. Thin-film solar panels also have the least life expectancy so, the monocrystalline solar panel would be best for your campervan.
