Please do not scratch the surface of the solar panel with sharp objects. 2. Please expose the solar panel to direct sunlight to ensure the best charging speed when charging. 3. Please do not place the charger in rainy days, otherwise it will cause a short circuit. 4. The 18V500W solar panel charger has a built-in anti-current resistance, which will not cause backflow. packing list: 2 x 500W solar panel 1Controller (40A) We will provide you the corresponding controller according to the total wattage of the solar panel you purchased. Review: NOT 500w - was offered a return if I paid postage and this is not UK. Panels are more like 50w, will try via credit card company for misleading description and item not fit for purpose. Review: No wiring - No wiring came with the solar panel kit. Me and a mate ordered 2 sets at the same time and neither kit came with any wiring. ## Features - 【Material】Solar panels use ETFE. ETFE material has higher light transmittance and longer service life than ordinary materials. ETFE material guarantees optimum performance day in and day out. The backplane adopts TPT, which has good heat dissipation, waterproof, high temperature resistance and easy cleaning. - [Safe and efficient] The conversion rate of monocrystalline silicon solar panels can reach 19.8%~21%. The junction box has a built-in diode, which can reverse charge the battery to prevent leakage at night. It can effectively convert light energy into electric energy, realize safe power supply, energy saving and environmental protection. It also performs well in extreme lighting conditions. - 【High conversion efficiency, can also be used in low light environment】This solar panel adopts monocrystalline silicon, which can achieve high power generation efficiency of more than 21%. Ordinary solar chargers are less efficient at generating electricity in low-light environments. This solar panel uses a unique material to generate electricity even at night or in low-light environments. - 【You will get】2pcs flexible solar panel 500W 18V 40A solar controller, 2m cable with PV connector, 1m cable with alligator clip, 2-in-1 adapter, user manual and friendly customer service. - 【Semi-Flexible】Plastic back panel can be bent up to a maximum of 30 degree arc and can be installed on RV, boat, cabin, tent, car, truck, trailer or any other uneven surface. With good walkability, it is suitable for areas without electricity and inconvenient urban traffic. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BHRRF5MP | | Amperage Capacity | 8.5 Amps | | Best Sellers Rank | 176,627 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 669 in Monocrystalline Solar Panels | | Brand | BEIJIAYI | | Connector Type | MC4 | | Customer Reviews | 1.0 out of 5 stars 4 Reviews | | Efficiency | 21% | | Included Components | 2 solar panels, 40A controller, 2m cable with PV connector, 1m alligator clip, 2-in-1 adapter, user manual, friendly customer service | | Included components | 2 solar panels, 40A controller, 2m cable with PV connector, 1m alligator clip, 2-in-1 adapter, user manual, friendly customer service Included components 2 solar panels, 40A controller, 2m cable with PV connector, 1m alligator clip, 2-in-1 adapter, user manual, friendly customer service See more | | Item Dimensions L x W x H | 77.5L x 50W x 77.5H centimetres | | Item Weight | 2 Kilograms | | Item weight | 2 Kilograms | | Manufacturer | BEIJIAYI | | Material | Monocrystalline Silicon | | Maximum Power | 500 Watts | | Maximum Voltage | 18 Volts | | Model Number | efb57787-5c8c-4fb1-8bce-516dbacc50d0 | | Part Number | Solar Panel | | Product dimensions | 77.5L x 50W x 77.5H centimetres | | Special Features | Semi-Flexible | | Unit Count | 1.0 count | | Upper Temperature Rating | 80 Degrees Celsius | ## Product Details - **Brand:** BEIJIAYI - **Efficiency:** 21% - **Item weight:** 2 Kilograms - **Material:** Monocrystalline Silicon - **Product dimensions:** 77.5L x 50W x 77.5H centimetres ## Images ![1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - Image 1](https://m.media-amazon.com/images/I/71uLVL8VR5L.jpg) ![1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - Image 2](https://m.media-amazon.com/images/I/71emg38zO0L.jpg) ![1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - Image 3](https://m.media-amazon.com/images/I/71GT72kAJSL.jpg) ![1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - Image 4](https://m.media-amazon.com/images/I/71pC+-Mu8UL.jpg) ![1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - Image 5](https://m.media-amazon.com/images/I/715jP41nzFL.jpg) ## Customer Reviews ### ⭐ NOT 500w *by D***S on 10 September 2024* was offered a return if I paid postage and this is not UK. Panels are more like 50w, will try via credit card company for misleading description and item not fit for purpose. ### ⭐ No wiring *by N***T on 25 November 2023* No wiring came with the solar panel kit. Me and a mate ordered 2 sets at the same time and neither kit came with any wiring. ### ⭐ DO NOT BUY - THEY ARE NOT 500W panels *by C***A on 21 August 2024* Once again Amazon allows sellers to advertise blatant lies about products. These are claimed to be 500W each, however if you read on, the product description as inserted by the seller clerly shows that they are not capable of developing 1/2 that. Using their 21.6V at 8.9A ( Actually these figures are impossible to obtain together, peak voltages and peak currents cannot happen at the same instance) calculates to just 192W. (Ohms law, simple math, voltage multiplied by current equals Watts) ## Frequently Bought Together - BEIJIAYI 1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports - URAQT Solar Cable Y-Splitter (1 to 2), 2 Pcs Solar PV Parallel Adapter Y Cable Connector, Solar Panel Extension Cable MMF+FFM for Parallel Photovoltaic Connection, Solar Panel Charging - Solar Panel PV Cable DC Rated Black 4mm²/6mm² - Quality Wire by LukAro (5 meters, 4mm² Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/483320508-1000w-solar-panel-kit-2pcs-500w-flexible-solar-panel-off](https://www.desertcart.pl/products/483320508-1000w-solar-panel-kit-2pcs-500w-flexible-solar-panel-off) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-27*
