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 achieves three key benefits through its optimized "lightweight design + foldable/rollable structure + rapid deployment": 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 (industry average ≥100g/W); ultra-thin/frameless construction, folded at 3-5cm (2-3cm when unfolded), making it easy to fit into RV storage compartments (such as drawer-style storage compartments and side compartments).

　　Storage and Deployment Efficiency:

　　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, 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. A 1.5m quick-connect cable is included 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 tolerance of ±3%), 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/㎡ of sunlight), ensuring power delivery even in cloudy weather. With a temperature coefficient of -0.38%/°C, power degradation is only 15% (compared to 20% for conventional panels) even at high summer temperatures (60°C) on RV rooftops, preventing high temperatures from affecting power generation.

　　(III) Basic Weather Resistance (Suitable for Camping and Outdoor Environments)

　　IP rating: IP65 (front splashproof, back dustproof), can withstand light rain (≤10mm/h), preventing damage from sudden downpours while camping; the flexible version has an IP64 (splashproof) rating and should be protected from prolonged exposure to 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 (if accidentally stepped on); the rollable version has a bend radius of ≥30cm to prevent cell breakage 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). The edges are rounded to prevent scratches, and only mini aluminum alloy fixings are retained at the four corners (replacing the full frame, reducing weight by another 20%).

　　Roll-Up Model: This model lacks a glass cover and utilizes a 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 (thickness 0.15mm, compared to 0.25mm for conventional models), and the encapsulation layer utilizes a low-viscosity, ultra-thin EVA film (thickness 0.3mm, compared to 0.45mm for conventional models). 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 models (dimensions 40×30×15mm) and utilizes lightweight ABS+PC material (weighing ≤20g). The connectors utilize nylon housings (weighing ≤5g each), and the cables utilize 16AWG weather-resistant wire (20% lighter than conventional 14AWG wire).

　　(II) Optimized Folding/Rolling Structure (Improved Storage Efficiency)

　　Folding Hinge Design:

　　Nylon + 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 has 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. When unfolded, 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 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 drove a Type B RV (which can only accommodate one 100W fixed panel on the roof) and paired it with a highly portable 100W foldable panel (weighing 7kg, with a storage volume of 0.04m³, and stored in the rear compartment). While camping in Xinjiang during the day, the portable panel was unfolded on the roof in a sunny spot (with the bracket adjusted to a 30° angle). It combined with the fixed panel to generate power, generating an average daily total of 1.8kWh, enough to 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 was stored in a 12V/100Ah lithium battery, eliminating the problem of insufficient power from the fixed panel.

　　Trailer Camping:

　　A family camping in a trailer used a 100W rollable portable power board (weighing 6kg and stored in the trailer compartment after rolling up). Due to tree cover in the campground, the board was unfolded 20 meters away in an open area (with sufficient cable length). Using the bracket, the board adjusted its angle to track the sun's rays. Over the course of three afternoon hours, it generated 0.3kWh of electricity, allowing them to charge their children's tablets in a timely manner and avoiding the "power anxiety" caused by the fixed board being blocked.

　　Emergency Power Scenario:

　　While camping in the mountains, a user's RV generator failed. Using only a single 100W portable foldable power board (which unfolds in 40 seconds), the board generated 0.9kWh of electricity from 9:00 AM to 4:00 PM (5 hours of effective sunlight). This generated 0.9kWh of electricity, meeting the RV's water pump (10W for 1 hour), charging their phone (0.1kWh), and providing nighttime lighting, allowing them to power their RV until help arrived the next day. This demonstrates the portable power board's value as an "emergency backup."

　　V. Key Selection Considerations (Focusing on RV Camping Needs)

　　Prioritize Portability:

　　Weight: Choose a model weighing 6-8kg (single-person carryable, 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 size ≤700×300×5mm (compatible with RV drawer-style storage compartments). For rollable models, choose a diameter ≤15cm and a length ≤60cm (easy to fit into side compartments).

　　Deployment Time: Choose a model that takes ≤1 minute from "unlock the buckle - unfold - place the stand" 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 check if the board has a serial port).

　　Compatibility: Verify compatibility with MPPT controllers commonly used in RVs (PWM controllers are less efficient, so boards that support MPPT are preferred) to avoid loss of charging efficiency.

　　Basic Weather Resistance and Durability:

　　Protection Rating: 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 due to footsteps. For roll-up models, ensure a bend radius ≥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 a 1.5-2m long cable (long enough to reach from the ground to the RV connector), with 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 frequent, so durability is important). Avoid low-cost models with only a 1-2 year warranty (which can be easily damaged).
