The best solar panels for independent living
What are the best solar panels for van conversions? This article breaks down this potentially overwhelming and time-consuming topic once and for all. Solar panels are a valuable investment when converting an RV because they make off-grid living easier and more comfortable. You might think it’s a big investment, but there are many benefits to installing solar panels on your van.
Solar panels allow you to charge your batteries without being connected to shore power. This allows you to run everyday items such as lights, refrigerators, water pumps, and power sockets that help you charge your laptop, mobile phone, and any other device regularly.
Many companies now offer solar panels to those who want to make the switch. Therefore, it is important to ensure that you purchase high-quality solar panels that will both generate electricity and save energy. However, we know that with so many different brands, types and styles currently on the market, finding a product that suits you and your needs is not always easy.
Finding the Best Solar Panel Option: A Comprehensive Guide to Daily Power Consumption
Are you considering going solar but unsure where to start? Choosing the right solar panel option can be overwhelming, especially with the myriad of choices available. However, understanding your power consumption and how you plan to use the solar panels can simplify the process. In this guide, we’ll walk you through how to calculate your daily power consumption in watt-hours and choose the best solar panel for your needs.
Understanding Solar Power Basics
Before diving into calculations, let’s clarify a few key terms:
Watt (W): A unit of power.
Watt-hour (Wh): A measure of energy consumption that represents the amount of energy used over time. For example, a 100W bulb running for 10 hours uses 1,000Wh or 1kWh.
Step 1: Determine Your Daily Power Consumption
You will quickly realize that most solar panels for van conversions come with either 50w, 100w, or 200w of power. Therefore, it is important to understand how you will use your solar panels to determine which will be best for you. When trying to work this out, you will also need to look at the watt-hours (Wh), which determines how much your daily power consumption would be.
We recommend that most campervans have a minimum of 80 watts, and this is because (and these are minimum expectations and dependent on weather conditions)
With 80 watts, you should be able to use your lights, water pump, and radio for at least 2 hours a day.
With 85 watts, you should be able to use your lights, water pump, and radio for at least 3 hours a day.
With 130 watts, you should be able to use your lights, water pump, and radio for 5 hours per day.
As a general rule, a 100w panel will supply around 400Wh of power a day which would easily cover your lighting for approximately 6 hours per day while watching a TV.
List Your Appliances
Make a list of all the electrical appliances you use regularly. Common household items include:
Refrigerators
Lights
Televisions
Computers
Heating/Cooling systems
Find the Wattage
Next to each appliance on your list, note its wattage. This information can usually be found on a label on the device or in the user manual. If you’re unsure, here’s a quick reference for common appliances:
Appliance | Power (Watts)
LED Light Bulb | 10-15 W
Laptop | 50-100 W
Refrigerator | 150-800 W
Microwave | 600-1,200 W
Air Conditioner | 1,000-2,500 W
Calculate Daily Usage
Now that you have the wattage, estimate how many hours each appliance is used daily. Multiply the wattage by the number of hours to find the daily consumption in watt-hours.
Example Calculation:
LED Light Bulb: 15W x 5 hours = 75Wh
Laptop: 100W x 6 hours = 600Wh
How effective are campervan solar panels?
It depends on the system you choose, but there are solar panels that are incredibly effective and long-lasting. Make sure you find the proper system for your setup and check reviews before purchasing. We have created a list of great solar panel options depending on your energy needs and can offer plenty of power to keep you happily on the road.
Fixed Vs. Portable Campervan Solar Panels
Fixed vs. Portable solar panels are an essential and frequent question those converting campervans ask. In short, portable solar panels must be positioned manually and require daily setup. In contrast, the fixed solar panels will typically be permanently mounted to the roof of your camper.
Aside from the initial system setup and installation, fixed solar panels for the van roof require no additional setup and will passively collect energy and hold it for you. Likewise, if you have an alternator hooked up, you will be charging your batteries when driving, which is crucial if you are in areas with less sun or have a smaller system.
Portable solar panels are also an excellent choice if you only have a small roof or would like the flexibility that comes with being able to set up your panels to face the sun and maximize their potential. However, if you own a larger campervan or motorhome, it may make sense not to worry about daily setup and use fixed solar panels instead.
Rigid Vs. Flexible Campervan Solar Panels
In the past, the best solar panels have been more rigid and used by more people. However, it is vital to remember that most but not all rigid solar panels weigh more than the average flexible panels and are often bolted or mounted directly onto the camper roof, which may be an issue for some.
Rigid panels are far more durable as they use temperate glass. In addition, they have protected aluminum frames that can withstand extremely harsh temperatures – both heat and cold – plus other external elements like winds, snow, and ice.
Flexible panels are very popular for stealth camping. They weigh less than 6 pounds, are extremely thin, and are less obvious on a roof. In addition, they are adjustable, making them easier to set up and use immediately. The flexible panels come in portable and fixed options.
If price is a factor for you, the rigid solar panels may still be the best for van conversion because they tend to be cheaper, making it the right choice for the money-conscious among us.
Monocrystalline vs. Polycrystalline Solar Panels
You also need to consider whether you want a single or blended source of solar gathering.
It may sound like an alien subject, but it is essential to understand.
Both solar panels have specific pros and cons, so it does come down to personal preference and your intended use.
Monocrystalline panels are more expensive up front, but they are more effective. So, in theory, you shouldn’t need as many panels, and the cost will equal. Monocrystalline panels are around 20% more efficient but are about 20% more expensive.
Polycrystalline solar panel cells are made of multiple silicon crystals, making them less efficient but more affordable. In contrast, monocrystalline panels are made of single crystals, offering higher efficiency at a higher price.
Monocrystalline panels often come at a higher price point, but they will save you space. On the other hand, polycrystalline solar panels are recommended when you want to reduce upfront costs, and space is not a limitation. Therefore, if your campervan is on the smaller side, you may decide that monocrystalline panels will better suit your needs.
