Certainly. Most commercial solar panels (e.g., Anker Solar Panel 625) offer at least 100W of output and combining them yields much higher wattage (up to several hundred watts), which is sufficient to power up most devices in a solar panel trailer, including lights, fridges, coffee makers and so on.

Moreover, solar panels are often used together with portable power stations, which can store the generated solar energy for later use. In short, it is a totally feasible solution to power your travel trailer with solar panels.

Basically, this question is reduced to how much power you’ll need and what wattage a single panel can offer. But as a rule of thumb, a 100W solar panel for travel trailers is enough to power some small appliances, including lights and chargers. More panels are needed if you want larger appliances and your electric RV trailer operational during your outing too. In this case, consider products like the 200w Anker 531 Solar Panel together with large power stations to have a broader scope of choices in electricity use outdoors.

Whether a 100W solar panel is enough for your travel trailer depends on how much energy you plan to use during your travel. 100W is really a tight energy budget for a travel trailer with solar panels, since it may not power much. While it can power basic devices like lights, lamps, and common electronics like cell phones and laptops, a bare 100W may not be enough for larger appliances like TVs or air conditioners. In this case, you need to make an addition of solar panels or employ higher wattage panels.

To size a solar panel for a travel trailer, several factors need to be considered.

1. Energy Consumption:Determine your power requirements by assessing the energy consumption of your appliances and devices.
2. Daily Energy Demand: Calculate the daily energy demand in watt-hours.
3. Daily Energy Available:Consider the average sun hours in your location to estimate the daily solar energy available.
4. Solar Panel Capacity:Divide the daily energy demand by the daily solar energy to determine the minimum panel capacity in watts.
5. Type and Efficiency of Solar Panels:Consider the type and efficiency of the solar panels, as well as any additional factors like shading or tilt angleto decide the size of solar panels. It's recommended to prepare additional solar panels or use a complete set of solar generators for sufficient and efficient power supply to travel trailers.

Powering an AC in a travel trailer is a much more challenging task using solar panels only. Generally, it takes a minimum of 1500W on average to run the AC, which can translate to eight 200W solar panels or sixteen 100W solar panels. However, if you use a large-capacity portable power station or a solar generator together, three 100w panels or two 200w panels plus a large Anker powerhouse will be generally sufficient to power the AC in a travel trailer.
