The advantages of a lightweight caravan system.

Caravans are becoming the first choice of travel for more and more people who want to be free and far away. As a moveable home, a train is not only a vehicle for a self-drive journey but also a combination of "room" and "car". More and more people are looking for a caravan with the power and convenience of a car and the comfort and safety of a "room".
In response to this market demand, caravans are now showing a development trend towards a lightweight and low center of gravity, and caravan photovoltaic systems are also developing.

The lighter the weight, the lower the center of gravity.

 the more stable the handling and the higher the safety

Qualified flexible modules are light in weight, for example, Shawllar's flexible modules are only 14 kg per 1KW, while the rigid panels commonly available on the market weigh around 70 kg per 1KW. Compared to flexible modules, the installation of rigid panels per 1000W is equivalent to an additional 56Kg on top of the caravan, which will significantly increase the vehicle's wind resistance and shift the vehicle's center of gravity.

The higher the vehicle's center of gravity, the greater the impact of cornering and side winds during driving, which has a significant impact on the comfort, handling, and stability of the vehicle. The increase in wind resistance will cause a change in the center of gravity during driving and increase safety uncertainty, especially with hollow-mounted rigid panels. This is not the case with flexible components, which are mounted close to the roof and basically do not cause wind resistance.

The lower the wind resistance, the lower the fuel 

The extra weight of the rigid module increases the cost of fuel consumption in addition to the safety risks. According to rough calculations, for every 50 kg increase in the weight of the caravan and when the speed is maintained at 80 km/h, the extra fuel cost will be more than 400 yuan per 20,000 km of driving. The advantages of flexible modules are very obvious, and while they bring the convenience of electricity, they are also far safer than hard panel modules and will be the first choice for caravan photovoltaic systems.

Portable installation and self-cleaning powerest

Some of the hard panels on the market are currently installed with holes in the roof, causing damage to the roof of the caravan. Shawllar's flexible components are directly attached with structural adhesive and can be adapted to a wide range of caravan roofs without damaging the original roof structure, resulting in easy installation, no wind resistance, and low fuel consumption.

Moreover, the hard panels are surrounded by a border higher than the glass, forming a concave shape on the surface, which aggravates the accumulation of water and dust and seriously affects the power generation capacity, requiring frequent scrubbing of the modules. The Shawllar's flexible modules, on the other hand, have a flat and smooth surface that is less prone to dust accumulation and can be kept clean by daily rain.

With the general trend of lightweight caravans, certified flexible and efficient modules from large manufacturers will be the future of caravan photovoltaic systems. The lighter, more efficient, safer, and more professional RV PV power supply system will be favored and chosen by more and more users, and Little Blue Technology will continue to provide professional products and services for the RV market in the RV PV system.
