Why RV should install solar panels

Relative to the traditional vehicle power supply, generator power, solar panels to generate electricity in the caravan travel to meet the basic needs of electricity and no noise, environmental protection, put convenient, and other factors that make caravanning travel enthusiasts gradually choose to install solar panels to supply electricity needs, the installation of solar panels of the capital requirements are also in a reasonable range.

Types of solar panels installed on caravans

(1) Regular Solar panel

Advantages: ① cheap, regular solar panels are the cheapest of all solar panels in the cheapest category, for poor travel enthusiasts is a good choice. ② high power generation Compared to the soft plate for a 250w hard plate and 400w soft plate in the same environment is about the same power generation.

Disadvantages: ① perforation, mounting bracket, for non-professional caravans considering the vehicle speed car will generally be designed for the arc, so that the installation of solar hard panels need to be installed on the roof of the roof perforation mounting bracket, taking into account the residence of the caravan perforation will make the vehicle leakage, and the other in the roof installation of the crossbar needs to be applied to the vehicle modification.

② Vehicle audit, vehicle annual safety factor audit needs to be removed from the solar hard plate

③ clean up the vehicle in a long time in the use of solar panels will appear on the surface of a variety of obstructions, in order to ensure the efficiency of power generation needs to be cleaned up in a timely manner, due to the installation of the top of the caravan to clean up is very troublesome

④ easy to damage, solar panels brittle texture of hard panels encountered falling rocks, hail and other hard panels than soft panels are more likely to be damaged

(2) Flexible solar panels

Advantages: ① easy to install, flexible panels are extremely simple to install, do not have to consider the shape of the roof, just a simple tape can be fixed on the surface of the car ② light weight, no wind resistance, does not affect the weight of the car. For the hard board soft board thin and light, the overall impact on the vehicle is almost no, it is tightly attached to the car surface will not affect the car’s driving speed.

Disadvantages: expensive, and the same power of the hard plate for the soft plate price is about 3 times the hard plate, ② low life soft plate life is generally 2 to 3 years relative to the hard plate life is much shorter ③ damage to the vehicle, the soft solar panels tightly attached to the top of the vehicle, the prolonged period of high temperature will make the vehicle top of the roof is damaged, affecting the aesthetics and the impact of the vehicle’s secondary out of value!

(3) Foldable solar panels

Advantages: adjustable, space-saving, long life. Foldable solar panels need to be taken out of the car to the sun when used to generate electricity, saving space on the roof of the car, can be stored items, due to long exposure to the outdoors folded solar panels do not need a long time to the life of the solar panels is also much longer.

Disadvantages: inconvenient, easy to discard. Due to the use of the need to take out of the car cannot be generated at any time, in the power generation is not very convenient, and secondly, when charging people need to be next to the solar panels, in public places easy to be stolen by others. At the same time, the price is relatively expensive.

Caravan solar panel material selection

(1) Monocrystalline silicon solar panels, power generation in direct sunlight is more efficient, but high temperature performance conversion rate will be affected, monocrystalline intergroup life than polycrystalline components of the life of a longer period of time

(2) Polycrystalline silicon solar panels, polycrystalline silicon for diffuse light is more sensitive to shade, cloudy and rainy days have less impact on it, conversion efficiency

Higher than monocrystalline silicon, good low light, high temperature performance has a good performance, polycrystalline silicon price is cheaper than monocrystalline silicon, conversion efficiency than monocrystalline silicon slow decay

(3) Amorphous silicon solar panels, the first two kinds of waste of silicon crystals, amorphous silicon on the absorption of radiation in a wider range, thinner, lower cost, in the same light conditions than monocrystalline silicon power generation is higher by 15%!

What do I need to pay attention to when installing RV solar panels?

(1) heat dissipation, solar panels in a high-temperature environment will greatly reduce the efficiency of power generation, do a good job of solar panels heat dissipation is necessary.

(2) Battery. Weather is the main impact, in order to prevent continuous rainy days, prepare a battery in case of emergency.

Can RV solar panels support high-power appliances

In fact, solar panels are only related to power generation, as for the power is related to the inverter, to drive the refrigerator and air conditioner, induction cooker and other high-power appliances need a higher power inverter. At the same time whether to support the caravan can also be installed with solar panels related to the area, can not be maintained for a long time is not recommended to use!

Solar charge controller selection

(1) PWM solar charge controller, this controller, although the technology is more mature, but the conversion efficiency is low general selection of lower

(2) MPPT solar charge controller, more efficient MPPT controller is equipped with an intelligent monitoring system, can monitor the solar panel power generation of the highest pressure, control battery charging for the highest efficiency, so that charging efficiency is higher, intelligent design is the most suitable for solar caravan controller.

Summarize

The choice of caravan solar panels need to consider their own economy and convenience, choose solar panels as caravan power generation is fully meet the needs.
