I. Targeting and Core Value (Addressing the Pain Points of RV Camping)

　　The 100W portable solar panel for RV camping is a core portable energy component for off-grid power supply in RVs. Suitable for outdoor camping in self-propelled and trailered RVs, it addresses the core pain points of traditional RV energy supply: First, fixed solar panels on RV roofs are limited by roof area (e.g., small RVs can only accommodate one or two 100W panels, resulting in insufficient power generation) and cannot be adjusted to suit sunlight angles. Second, conventional portable solar panels (weighing ≥10kg and storing a volume ≥0.1m³) are difficult to carry, require large storage compartments, and require 3-5 minutes to deploy, making them difficult to meet the requirements for "quick charging and flexible storage" when camping. The highly portable 100W model, optimized through a lightweight design, foldable/rollable structure, and rapid deployment, achieves three core benefits: weight is controlled at 6-8kg (easily carried by one person), storage volume is compressed to 0.03-0.05m³ (approximately the size of a 15-inch laptop), and deployment/folding time is ≤ 1 minute. It is also compatible with RV 12V/24V energy storage systems and can be flexibly deployed and moved according to sunlight angles. At campsites, it generates an average daily power of 0.8-1.2kWh, meeting the needs of RV refrigerators (50W), LED lighting (10W x 3), and mobile phone/laptop charging, eliminating reliance on RV generators or campsite charging stations. II. Core Performance Parameters (Balancing Portability and Practicality)

　　(I) Core Portability Indicators (Key Differentiation)

　　Lightweight Design: Overall weight 6-8kg (compared to 10-12kg for traditional portable boards), unit power weight ≤80g/W (compared to ≥100g/W for the industry average); Ultra-thin/frameless construction, 3-5cm thick when folded (2-3cm when unfolded), making it easy to fit into RV storage compartments (such as drawer-style storage compartments and side compartments). Efficient Storage and Deployment:

　　Folding Version: Two-fold or three-fold design, unfolded dimensions: 1400 × 600 × 2mm, folded dimensions: 700 × 300 × 5mm (about the size of a briefcase). Hinged connection: To unfold, simply unlock the latch and lay flat.

　　Roll-Up Version (Flexible): Utilizing a PET flexible backsheet, rolled up diameter ≤ 15cm and length ≤ 60cm (storage similar to a yoga mat), unfolded dimensions: 1600 × 500 × 1mm. No rigid frame, suitable for deployment on the side of an RV or on the ground.

　　Easy Deployment: Includes a foldable mini stand (unfolded height: 15-30cm, weight: ≤ 500g), requiring no additional tools. The stand's angle is adjustable (0°-45°) to accommodate varying sunlight angles. It comes with a 1.5m MC4 quick-connect cable for direct plug-and-play connection to an RV energy storage inverter or lithium battery. (II) Electrical Performance and RV Compatibility

　　Compatible with RV energy storage systems: Under standard test conditions (STC), rated power is 100W (with a ±3% tolerance), operating voltage (Vmpp) is 28-32V (compatible with 12V RV energy storage batteries, charging efficiency ≥90%), and operating current (Impp) is 3.1-3.4A. Supports two modules in series (Vmpp 56-64V) for 24V RV systems, meeting the power requirements of higher-power devices (such as small parking air conditioners).

　　Low-light and outdoor compatibility: Power output is ≥55% of the rated value on cloudy days/under the shade (200W/㎡), ensuring power delivery even in cloudy weather. With a temperature coefficient of -0.38%/°C, even at high summer temperatures (60°C) on an RV roof, power degradation is only 15% (compared to 20% for standard panels), preventing high temperatures from affecting power generation. (III) Basic Weather Resistance (Suitable for Camping and Outdoor Environments)

　　Protection Rating: IP65 (front splashproof, rear dustproof), can withstand light rain (≤10mm/h), preventing damage from sudden rain during camping; the flexible version has an IP64 (splashproof) rating and should be protected from prolonged rain.

　　Mechanical Resistance: The folding version features a 1.0mm thick aircraft-grade aluminum alloy frame (compared to 1.5mm for traditional models). Despite its reduced weight, it can still withstand a static pressure of 5kg (e.g., if accidentally stepped on); the rollable version has a bend radius of ≥30cm to prevent cell fracture during folding. III. Technical Path to High Portability (Core Optimization Direction)

　　(I) Lightweight Material System (Key to Weight Reduction)

　　Ultra-thin Cover and Frameless Design:

　　Folding Model: Ditches traditional 3.2mm ultra-clear tempered glass for 2.0mm ultra-thin tempered glass (light transmittance ≥ 93%, 30% weight reduction). Edges are rounded for scratch resistance, with only mini aluminum alloy fixings at the four corners (replacing a full frame, reducing weight by another 20%).

　　Roll-Up Model: No glass cover, using transparent PET (polyethylene terephthalate) film (0.2mm thick) with a weather-resistant coating. It weighs only 1/10 of glass and offers a certain degree of scratch resistance (surface hardness ≥ 3H). Lightweight Backsheet and Encapsulation Layer:

　　The backsheet utilizes an ultra-thin TPT composite film (0.15mm thick, compared to 0.25mm for conventional designs), and the encapsulation layer utilizes a low-viscosity, ultra-thin EVA film (0.3mm thick, compared to 0.45mm for conventional designs). This reduces overall material thickness by 30% and weight by 25%.

　　Miniaturized Accessories:

　　The junction box is reduced in size to half that of conventional designs (40×30×15mm) and utilizes lightweight ABS+PC materials (weighing ≤20g). The MC4 connector utilizes a nylon housing (weighing ≤5g per connector), and the cable utilizes 16AWG weather-resistant wire (20% lighter than conventional 14AWG wire). (II) Optimized Folding/Rolling Structure (Improved Storage Efficiency)

　　Folding Hinge Design:

　　Nylon and glass fiber reinforced hinges (weighing ≤10g each) are used instead of metal hinges (weighing ≥25g each). Each panel requires only 2-3 hinges (2 for the two-fold model, 3 for the three-fold model), and the gap after folding is ≤2mm. The hinges have built-in locking buckles that automatically secure when unfolded, preventing wind-induced folding during camping.

　　Rolling Flexible Structure:

　　The cells use 166mm×166mm ultra-thin monocrystalline silicon wafers (150μm thickness, compared to 180μm for traditional models). Flexible copper tape (0.1mm thickness) is used for soldering to prevent cell breakage during winding. The backsheet features a built-in fiber reinforcement layer (polyester fiber) to improve tear resistance during winding (tear strength ≥20N/cm). (III) Quick Deployment Detailed Design (Ensuring Camping Convenience)

　　Integrated Mini Stand:

　　The folding model features slots on both sides of the frame. The stand utilizes a foldable aluminum alloy pole (which forms a triangular support when unfolded). Weighing only 400g, it can be adjusted to three angles (15°, 30°, and 45°) to accommodate different sunlight exposures during the morning, midday, and afternoon hours, eliminating the need to carry a separate stand.

　　Plug-and-Play Connection:

　　The cable comes pre-wired with MC4 male and female connectors (with waterproof and dustproof caps) and is 1.5m long (enough for ground deployment to the power storage port on the side of the RV). The connector is marked with "positive/negative" polarity to prevent reverse connection. No need to strip or wire cables while camping—just plug in and charge! IV. RV Camping Application Demonstration (Scenario-Based Value)

　　Camping in a Small Self-Propelled RV (Type B):

　　A user drives a Type B RV (which can only accommodate one 100W fixed panel on the roof) and pairs it with a highly portable 100W foldable panel (weighing 7kg and storing in the rear compartment). While camping in Xinjiang during the day, the portable panel is unfolded on the roof in a sunny spot (with the bracket adjusted to a 30° angle). This synergistically generates power in conjunction with the fixed panel, generating an average daily output of 1.8kWh. This power can power a 50L RV refrigerator (running 24 hours a day, consuming 1.2kWh), charge two laptops (0.3kWh), and power LED lighting (0.1kWh). The remaining 0.2kWh is stored in a 12V/100Ah lithium battery, eliminating the problem of insufficient power from the fixed panel. Trailer camping:

　　A family used a 100W rollable portable power board (weighing 6kg and stored in the trailer compartment) while camping in their trailer. Due to tree cover in the campsite, they unfolded the board 20 meters away in an open area (the cable was long enough). Using a bracket to adjust the angle to track the sun, the board generated 0.3kWh of electricity over a three-hour afternoon, effectively charging their child's tablet and avoiding the "power anxiety" caused by the fixed board being blocked.

　　Emergency power supply scenario:

　　While camping in the mountains, a user's RV generator failed. Using only a 100W portable foldable power board (which unfolds in 40 seconds), the power board generated 0.9kWh from 9:00 AM to 4:00 PM (five hours of effective sunlight). This generated 0.9kWh of electricity from 9:00 AM to 4:00 PM (five hours of effective sunlight), meeting the needs of the RV's water pump (10W for one hour), charging their phone (0.1kWh), and providing nighttime lighting until help arrived the next day, demonstrating the portable power board's value as an "emergency backup." V. Key Selection Points (Focusing on RV Camping Needs)

　　Prioritize portability:

　　Weight: Choose a model between 6-8kg (capable of being carried by one person, avoiding the need for two people when camping). Avoid models weighing more than 8kg (which can be difficult to carry for extended periods).

　　Storage Dimensions: For foldable models, choose a folded size of ≤700×300×5mm (compatible with RV drawer-style storage compartments). For roll-up models, choose a diameter of ≤15cm and a length of ≤60cm (easily fit into side compartments).

　　Deployment Time: Choose a model that takes ≤1 minute from "unlock the clip - unfold - place the bracket" to avoid complex assembly (saving time when camping).

　　RV System Compatibility:

　　Voltage: For 12V RVs, choose a single board with a 28-32V VPMPP. For 24V RVs, choose two boards connected in series (be sure to confirm whether the board has a serial port).

　　Compatibility: Verify compatibility with commonly used MPPT controllers in RVs (if PWM controllers are inefficient, choose boards that support MPPT to avoid loss of charging efficiency). Basic Weather Resistance and Durability:

　　Ingress Protection: At least IP64 (light rainproof); IP65 (moderate rainproof) for rainy areas.

　　Structural Strength: For folding models, ensure the aluminum alloy frame is ≥1.0mm thick to prevent deformation from being stepped on. For roll-up models, ensure the bending radius is ≥30cm to prevent cracking.

　　Accessory Practicality:

　　Bracket: Choose one with an integrated bracket (no need to purchase separately) and adjustable angles (at least three angles).

　　Cable: Choose an MC4 cable that is 1.5-2m long (long enough to reach from the ground to the RV interface) and has a waterproof cap on the connector to protect against dust and water during camping.

　　Warranty: Choose a "5-year material warranty + 20-year power warranty" (RV camping is frequently used, so durability is important). Avoid low-cost models with only a 1-2 year warranty (which can be easily damaged).
