Thin Panel Flat Plate Solar Collector

Introduction

Across Asia, Africa, and Latin America, demand for clean, affordable heating energy is growing faster than ever.
To meet this need, Soletks Solar Group introduces the FPC Slim 50 Flat Plate Solar Collector — a next-generation solution that delivers high thermal efficiency, compact design, and long-term reliability for every type of project.

Built on more than a decade of manufacturing experience in solar thermal technology, Soletks Solar has engineered the Slim 50 to optimize energy conversion while reducing installation and logistics costs.
At only 50 mm thick, this ultra-slim collector sets a new benchmark for space saving and engineering efficiency in the global solar water heating system market.

A Smart Solution for Modern Energy Challenges

Energy prices, climate change, and urban space constraints are reshaping the way communities access heat and hot water.
The FPC Slim 50 responds to these challenges by offering a system that is:

• Highly efficient and reliable even under tropical and arid conditions.

• Slim and lightweight, allowing easy installation on rooftops and balconies.

• Economical to transport and maintain, reducing project costs by up to 30%.

• Compatible with various solar thermal applications, from domestic hot water to industrial pre-heating.

It is the perfect fit for distributors, contractors, and developers seeking high-return solar thermal solutions for homes, businesses, and public facilities.

Core Advantages

1. Slim 50 mm Structure – Compact Power Reimagined

The Slim 50 is one of the world’s thinnest flat plate solar collectors.
Its 50 mm profile reduces volume and weight by over 60% compared to standard models, cutting logistics expenses and enabling higher shipping density. For projects spread across remote regions or islands, this means fewer containers and lower carbon emissions.

• Optimized through Finite Element Design: Ensures mechanical strength and wind resistance with minimal material usage.

• Flexible Mounting Options: Can be installed flat or tilted, on roofs or facades.

• Urban Friendly: Ideal for dense city environments where roof area is limited.

2. High-Performance Insulation for Maximum Heat Retention

The collector uses high-pressure polyurethane foam injection to achieve superior thermal insulation. This process ensures even density and tight adhesion between the insulating layer and the collector body.

• Uniform Insulation Density: Minimizes heat loss during nighttime or cloudy conditions.

• High Adhesion Structure: Prevents air gaps and extends the collector’s service life.

• Weather-Proof Design: Maintains efficiency in humid tropics and dusty deserts alike.

For projects requiring continuous hot-water supply — such as hospitals or industrial plants — this insulation ensures stable performance 24/7.

3. Premium Aluminum Frame – Strength and Style

Each FPC Slim 50 is built with a customized corrosion-resistant aluminum alloy frame, treated by electrostatic coating and high-temperature curing. This gives the collector exceptional durability and a modern aesthetic that blends seamlessly with commercial architecture.

• Corrosion and Rust Resistance: Perfect for coastal resorts or industrial zones.

• Sleek Appearance: Adds visual value to hotels and residential projects.

• Light but Rigid: Simplifies mounting and reduces labor time on-site.

The result is a collector that delivers both engineering strength and architectural elegance — an ideal match for modern solar heating projects.

4. Comprehensive Quality Control

Soletks Solar operates under a strict quality management system covering each production stage — from raw material inspection to final testing. Every unit is certified under ISO 9806 and Solar Keymark protocols.

• Raw-Material Verification: All absorber plates and tempered glasses are tested for efficiency and safety.

• Process Monitoring: Automated inspection guarantees consistent quality.

• Performance Tests: Thermal efficiency, pressure resistance, and leak tightness are evaluated before shipment.

This quality discipline makes the FPC Slim 50 a trusted component for large-scale EPC projects and government-funded sustainability initiatives.

5. Installer-Friendly Design

Installation simplicity is central to the Slim 50 concept. Soletks Solar added details that make the collector safe, practical, and compatible with diverse systems.

• Threaded Anti-Rotation Connectors: Ensure secure, leak-proof connections.

• Rounded Edges: Reduce injury risk during handling.

• Modular Compatibility: Easily integrates into existing solar thermal systems or hybrid energy networks.

The result is faster assembly and lower project labor costs — a key advantage for regional installers and solar distributors.

6. Industrial-Scale Manufacturing Power

At its 53,000 m² plant, Soletks Solar runs fully automated production lines supported by robotic assembly and in-house testing labs.

• Short Lead Times: Optimized processes enable rapid delivery for urgent projects.

• Scalable Capacity: Flexible production meets bulk orders for wholesalers and EPC contracts.

• Sustainable Manufacturing: Eco-friendly procedures minimize waste and energy consumption.

Such industrial strength assures partners of stable supply and uniform quality — critical for expanding solar markets in Asia, Africa, and Latin America.

Comprehensive Applications

The FPC Slim 50 is not just a collector — it is a versatile solution adaptable to a wide range of projects:

• Residential Hot Water: Stable supply for homes, apartments, and rural communities.

• Commercial Buildings: Hotels, schools, offices, and public baths benefit from low-cost solar water heating.

• Swimming Pools: Efficiently extends swimming seasons without high electric bills.

• Industrial Pre-Heating: Delivers process heat for food processing, textile washing, and chemical industries.

For developing countries with rising energy demand, the FPC Slim 50 offers a proven path to reduce fossil fuel dependency and enhance energy security.
