Application Scenario
RVs, campers and trailer-mounted recreational vehicles are the core application scenarios of 240W flexible solar panels. The roof of the RV is mostly curved or lightweight panels, which cannot withstand the weight of rigid photovoltaic panels and the damage of punching installation. The 240W flexible board can be directly pasted or fixed on the roof with a 12V/24V battery, which can power the LED lighting of the RV, car refrigerator, mobile phone/notebook charging, and small ventilation fan to meet the basic electricity demand of short-distance living, and completely replace the noisy and high-pollution on-board generator.
Yachts, sailboats and other water carriers, the deck of the yacht and the top of the cabin are mostly special-shaped curved surfaces, and they are sensitive to the weight of the equipment. The weight of the 240W flexible board is only 1/3 – 1/2 of that of the traditional rigid board. It can bend and fit the surface of the hull, and has excellent salt spray and moisture resistance. It can power the navigation equipment, communication stations, fresh water circulation pumps, and small refrigerators on board, and solve the pain point of off-grid electricity consumption at sea. There is no need to frequently dock for charging or carry oil generators.
Outdoor camping and portable emergency power supply. For camping enthusiasts, the 240W flexible board can be folded and stored, and it is matched with a portable energy storage power supply to form a mobile power generation system. When camping, it is unfolded and laid on the ground or roof of the car, and uses sunlight to power camping lights, portable induction cookers, projectors, and outdoor audio to create a “zero-emission” outdoor living experience. At the same time, it can also be used as an emergency power supply to power home lighting, routers, and emergency communication equipment when the mains power is interrupted.
Small civilian buildings with special-shaped roofs are suitable for scenes where rigid photovoltaic panels cannot be installed on villa curved roofs, sun room domes, color steel tile pitched roofs, etc. The 240W flexible board can be directly pasted and fixed without punching holes, and will not damage the roof waterproof layer. It can power the garden lights, surveillance cameras, roof exhaust fans, and small household dehumidifiers of the building, and realize “spontaneous self-use” micro-off-grid power supply, especially suitable for users who have high requirements for the appearance of the building.
Small IoT devices and monitoring stations are used for low-power IoT devices such as security monitoring cameras, weather monitoring stations, hydrological monitoring equipment, and forest fire prevention sensors in the field. The 240W flexible board can be installed on the top of the monitoring rod or equipment box, and the battery can be used to continuously power the equipment, solving the problem of no mains power coverage in remote areas, achieving unattended long-term stable operation with extremely low maintenance costs.
Mobile booths and small commercial carriers, for small commercial carriers such as night market mobile dining trucks, stall trolleys, outdoor kiosks, etc., 240W flexible panels can be installed on the roof of the car or booth ceiling to provide power for the lighting, electronic scales, collection speakers, and small refrigerated display cabinets of the booth, getting rid of the dependence on mains or long power lines, enhancing the flexibility of operation, and at the same time meeting the business philosophy of low carbon and environmental protection.
FAQ
Q1:Why does the 240W Solar Panel fail to deliver as much as stated when in actual use?
A:In most cases,it is normal for a solar panel not to deliver its full nominal power.Some of the reasons why this happens,as well as some suggestions for getting closer to the nominal power figure,are given below.
1.Light intensity:The amount of light shining on the panel will result in fluctuations to the power output.You are more likely to achieve nominal power output figures closer to those obtained under test conditions when using the product on a clear day during the midday sun,than when using the product in the morning or later in the afternoon.Weather conditions will also affect the amount of sunlight that shines on the panel.For example,you are much less likely to achieve the figures for nomina power in hazy,cloudy or rainy conditions.
2.Surface Temperature:The temperature of the solar panel surface will also affect the amount of power generated The lower the surface temperature of the panel,the more power will be produced.For example,solar panels generate more power when used during the winter than during the summer,and this is completely normal.Solar panels generally reach temperatures close to 60°℃(140°F)during summer.This reduces nominal power by 10-15%,despite the higher levels of light shining on the panel.
3.The Angle of the Sunlight:Under good lighting conditions,the solar panel is able to stay where light hits perpendicular to the surface to achieve better light performance.However,most solar panels installed on the roof of an RV can only be installed in a tiled configuration,which prevents the panel(s)from being installed at the optimal angle,and this difference will result in a power output loss of approximately 5%-10%.
4.Panel Shading:The surface of the solar panel should not be shaded during use.Shading caused by shadows,foreign objects and glass can all greatly reduce power output.Performance issues caused by Malfunctioning Panels:If the panel still isn’t generating power or its output remains far below expected nominal power figures after addressing the issues above,there may be an issue with the panel itself, Please contact Customer Support for assistance.
Q2:How much power can the 240W Flexible Solar Panel generate under normal conditions?
A:This depends first and foremost on weather conditions,Generally speaking,on a clear day with no clouds in the sky,sunlight hitting the panel at a 90°angle usually generates 168W-192W of power in the 240W panel(current light conditions are normally 800-900 W/m²(74.3-83.6 W/ft²)with a panel temperature of 50°c(32°F)under test conditions.Nominal power ratings are based on 1,000 W/m²(92.9 W/ft²).In AM1.5 conditions with a panel temperature of 25°cunder test conditions.Power output figures close to nominal values were normally observed in the midday sun during the winter).
Q3:What are the usage temperature range and precautions for use for the 240W Panel?
A:The operating temperature range of the solar panel is-45℃ to 85°℃(-113°F to 185°F).Please read the instructions carefully before using the solar panel and minimize large bends during use to avoid damage to the battery core.
The panels are made of a special composite material,which is lightweight and able to bend to a certain degree.allowing them to be used flexibly on different surfaces of the roof.However,the solar panels are made of monocrystalline silicon wafers,and despite their flexibility,they should not be slammed on the ground during installation and use or stepped on or struck with foreign objects,Do not sit on the surface of the panels and do not bend the panels too far in order to prevent the monocrystalline wafers from breaking and affecting use.Damage caused by human force is not covered under the free warranty.
Q4:Does the bend of the 240W Panel have a large impact on power?
A:The solar panel can be bent on certain surfaces,but the more the panel bends,the less efficient it is.This is because panel power generation is best only when the entire panel has a consistent light source.When bent,different areas of the flexible solar panel are exposed to different amounts of light,reducing power generation efficiency.
Q5:Can luse 240W Solar Panels together in series?
A:Yes.Please read the description of in series and parallel connections in the User Manual carefully,paying particular attention to energy storage controller requirements and limitations on solar panel output,so as not to cause solar panels with different currents to be used in series without releasing their power and creating a 1+1<2 effect.
Q6:Can l connect 240W Solar Panels in parallel?
A:Yes.Connecting panels in parallel increases power through doubling the current.The maximum number of 240W panels allowed in a parallel connection depends on the controller and energy storage equipment of your recreational vehicle.Please ensure that the energy storage system used in your vehicle supports a higher input current,and you should use wires with a diameter suitable to the output current to securely connect the panels in parallel.
Q7:Dolneed to clean the 240W Solar Panel regularly?
A:Yes.There can be a lot of dust and foreign objects on the surface of the solar panel after the panel has been used outdoors for a long time,which block the light to a certain extent,reducing the power output.Regular cleaning can help keep the surface of the solar panel clean and free from obstructions and generate a higher power output.However,when cleaning,be careful to wipe the surface with soft materials to prevent hard materials scratching the surface of the panel and affecting the output.
