Proposal for a Solar Panel Cleaning System Designed for the Brazilian Market
This is the product proposal for the solar panel cleaning system designed for the Brazilian market, which integrates climate adaptability, cost-effectiveness, and intelligent management needs, with core elements derived from the documentation:
1. Core Cleaning Technology
- Waterless Dry Cleaning Mode: Uses ultra-flexible nylon spiral brushes (material PA610), with adjustable speeds of 60-120 RPM and a single cleaning efficiency of over 99%, perfectly suited for the water-scarce environments in drought-prone areas of Brazil.
- Optional Hybrid Cleaning: Supports both dry sweeping and water washing modes, with customizable water washing features to tackle stubborn stains in rainy seasons or high-pollution areas (such as industrial zones).
- Self-Cleaning Program: Automatically operates at high speed after tasks to remove accumulated dust from the brush, extending its lifespan.
2. Environmental Adaptability Design
- Weather Resistance: Operating temperature range of -30°C to 70°C, with an IP65 protection rating to withstand Brazil’s tropical heat, dust, and humid climates.
- Terrain Handling: Maximum climbing angle of 22° to adapt to the commonly seen inclined photovoltaic arrays in Brazil.
- High Coverage Efficiency: Cleans 1000m² per hour, with a walking speed of 12m/min, suitable for large-scale power plants.
3. Intelligent Management
- Remote Control: Supports 4G network, app, and cloud-based remote control, generating real-time work reports.
- Intelligent Scheduling: Automatically plans cleaning times based on weather data (e.g., avoiding midday high temperatures) to reduce energy consumption.
- Fault Self-Diagnosis: Automatically alerts for abnormal situations, with cloud diagnostics and remote repair to lower downtime risks.
4. Economic Benefits
| Comparison Item | Manual Cleaning Cost | Robot Cleaning Cost |
|---|---|---|
| Annual Cleaning for 1MW Plant (4 times over 15 years) | $81,000–$650,000 | $10,000–$20,000 (equipment investment) |
| Water and Electricity Costs | High | Zero water consumption |
Power Generation Gains: Reduces dust losses, increasing power generation efficiency by 10–65%.
5. Safety and Sustainability
- Zero Manual Operation: Eliminates risks of electric shock and falls from high-altitude work, avoiding damage to photovoltaic panels from stepping.
- Lifetime Service: Free software upgrades and localized technical support to ensure long-term stable operation.
6. Customization Suggestions for Brazil
- Corrosion-Resistant Components: Strengthen metal part coatings for coastal areas with high salinity in the air.
- Battery Optimization: 24V/16Ah battery designed for tropical heat, with added shading and cooling designs.
- Localized Support: Establish maintenance centers in São Paulo/Bahia, providing Portuguese operating interfaces.
This proposal integrates efficient cleaning, intelligent operation and maintenance, and cost advantages, significantly enhancing the return on investment for solar power plants in Brazil, particularly suitable for the northeastern drought-stricken areas, high-pollution cities like Rio de Janeiro, and distributed rooftop power stations.
