Flat Plate Solar Collector for Engineering Applications

Introduction

As one of the core products of Soletks Group in the renewable energy field, the Engineering Flat Plate Solar Collector is designed for large-scale hot water supply and central heating projects.
With the concept of 'modular connection, tailor-made scale', it can match the number of collectors to the actual hot water and heating needs of each project. This solves the common problems of oversized systems wasting money or undersized systems failing to meet demand.
Thanks to its low cost, easy installation, and long service life, it has become a preferred energy solution for engineering projects.

Key Advantages – Four Dimensions of Reliability

1. Pressure-Resistant Operation – Safe and Stable
   - Unlike household collectors that only work under low pressure, this collector uses a full-metal pressure chamber. It can be directly connected to project water or heating pipelines without extra stabilizers. Even in high-demand conditions (e.g., residential peaks or 24/7 hospital heating), it runs stably, preventing leaks or pipe bursts.

2. Flexible Customization – Fits Any Project
   - Scale customization: Based on daily hot water use or heating area, the system calculates the exact number of collectors needed—no waste, no shortage.
   - Interface customization: Inlet and outlet sizes can be tailored to existing pipe networks, saving renovation costs.

3. High Energy Efficiency – More Heat, Less Cost
   - Peak efficiency up to 0.79, turning more sunlight into usable heat.
   - 65% efficiency even in cloudy/low-light conditions, making it suitable for rainy or winter regions.
   - Heat loss <5% (vs. industry average ~8%), lowering energy waste and costs.

Application Scenarios – Five Major Fields

1. Residential Communities – Provides centralized hot water and heating for thousands of households.
2. Schools & Hospitals –
   - Schools: Stores solar heat during the day, supplies hot water for peak times (e.g., after evening classes).
   - Hospitals: Smart temperature control ensures reliable 24/7 hot water.
3. Factories & Enterprises – Supplies large amounts of hot water for processes (e.g., textile dyeing, food washing), reducing electricity/gas costs.
4. Greenhouses – Works with floor or air heating to keep temperatures stable (±2°C) without coal burning, improving crop yield.

Technical Highlights – Four Smart Designs

1. Selective Coating – Strong Heat Absorption
   Using vacuum magnetron sputtering, absorption >95%, effective even in weak sunlight.
2. Premium Glass Cover – Strong & Transparent
   - 92% light transmission
   - 5× impact resistance (hail-proof, falling objects)
   - Anti-glare surface to reduce light pollution
3. Integrated Insulation – Lower Heat Loss
   Seamless insulation keeps heat loss under 5%.
4. Easy Installation – Fast and Cost-Saving
   - Modular connection, 2 workers can install a unit (40% faster)
   - Supports roof, wall, or ground installation without major building changes
   - Pre-tested at factory, only needs pipeline connection onsite
