ATPC solar air collector
Solar Air Heating Collector
Fully Automatic, PV-Powered Solar Air Heating Solution
The ATPC Series Solar Air Heating Collector is a fully integrated solar air heating solution designed for direct space heating using clean solar energy.
By combining solar air collection, photovoltaic power generation, intelligent control, and forced air delivery into one compact unit, the ATPC series provides a reliable and maintenance-friendly heating option for residential and small commercial applications.
Unlike liquid-based solar thermal systems, ATPC uses air as the heat transfer medium, eliminating freezing risks, water leakage concerns, and complex hydraulic components.

How ATPC Works
System Operating Principle
Solar Absorption
Solar radiation is absorbed by the high-efficiency flat plate air collector.
Air Heating Inside the Collector
Ambient air enters the collector channel, where it is heated as it flows across the absorber surface.
PV-Powered Fan Operation
The integrated photovoltaic panel supplies power to the DC fan, ensuring airflow without grid electricity.
Automatic Temperature Control
The system operates automatically based on preset temperature thresholds, delivering warm air only when useful heat is available.
Direct Hot Air Delivery
Heated air is supplied directly to the indoor space, achieving fast and effective space heating.
Key Advantage
This direct air-to-air heat transfer avoids intermediate energy conversion losses and ensures quick thermal response. The ATPC system converts solar radiation directly into usable warm air through a streamlined and efficient process.
Key Technical Features
Engineering Advantages
Air-Based Heat Transfer System
Using air as the heat transfer medium eliminates:
Freezing risks in cold climates
Leakage and corrosion issues
The need for antifreeze or water treatment
This makes ATPC especially reliable for winter and high-altitude environments.
PV-Powered Fully Automatic Operation
The built-in photovoltaic module supplies power to:
DC circulation fan
Intelligent temperature controller
The system operates independently of the electrical grid, reducing operating costs and ensuring uninterrupted heating during daylight hours.
Integrated and Compact Design
All key components are integrated into a single unit:
PV power supply
Fan and control system
This reduces installation complexity, minimizes failure points, and shortens commissioning time.
Stable Performance in Cold and Harsh Conditions
The ATPC system maintains stable airflow and heat output even in low ambient temperatures.
Because no liquid circuits are involved, the system remains operational during freezing conditions without additional protection measures.
Low Maintenance and Long Service Life
With no pumps, valves, or liquid loops, routine maintenance is limited to:
Periodic surface cleaning
Visual inspection of electrical connections
4. Control Logic & Automatic Operation
The ATPC series features intelligent temperature-based control designed for unattended operation.
Automatic start when collector temperature exceeds the preset threshold
Automatic stop when solar heat is insufficient
Continuous self-regulation without manual adjustment
This ensures that only useful solar heat is delivered indoors, preventing unnecessary heat loss or cold air circulation.
5. System Configuration & Optional Components
Standard Configuration
Solar air heating collector
Integrated photovoltaic panel
DC circulation fan
Intelligent temperature controller
Optional Components
Air ducts and connectors
Additional temperature sensors

7. Typical Applications & Reference Scenarios
Where ATPC Delivers the Highest Practical Value
The ATPC Series is not designed as a universal heating solution for all scenarios.
Its value is maximized in applications where direct hot air supply, automatic operation, and system simplicity are more important than long-term heat storage or centralized hydronic distribution.
The following application scenarios represent technically validated and repeatable use cases, where ATPC provides clear advantages in performance, installation, and operating cost.
Residential Space Heating (Houses, Villas, Apartments)
Application Challenge
In many residential buildings, especially older houses and villas, installing a conventional hydronic heating system requires extensive piping, space for boilers or tanks, and long installation cycles. Electric heaters, while simple, often result in high operating costs.
Why ATPC Fits This Scenario
ATPC delivers direct warm air into living spaces during daytime hours, when solar radiation is available and heating demand is highest. The system operates automatically, requiring no daily user interaction.
Because there is no water circuit:
There is no risk of freezing
No need for antifreeze
No risk of leakage inside living spaces
Typical Configuration Logic
One or multiple ATPC units installed on sun-facing façades
Warm air ducted directly into frequently used rooms
Conventional heating systems (if present) remain as backup only
System Value
Reduced electricity or fuel consumption during daytime
Improved indoor comfort with fresh, preheated air
Minimal modification to existing buildings
Offices & Small Commercial Buildings
Application Challenge
Offices, shops, and small commercial buildings often require heating mainly during working hours. Running full-scale heating systems throughout the day leads to unnecessary energy consumption, especially in transitional seasons.
Why ATPC Is Effective
ATPC provides daytime solar-driven heating, perfectly aligned with office occupancy schedules. The system preheats incoming air, reducing the load on conventional HVAC systems without altering existing infrastructure.
Typical Configuration Logic
ATPC integrated as a pre-heating unit for fresh air intake
Independent operation alongside existing HVAC systems
Automatic start and stop based on solar conditions
System Value
Lower operational energy costs
Improved indoor air quality
Simple integration with minimal downtime
Public Facilities & Utility Buildings
(Public toilets, guard rooms, ticket booths, kiosks)
Application Challenge
These buildings are often:
Small in size
Distributed across wide areas
Expensive to heat using centralized systems
Running electric or fuel-based heaters continuously results in high costs relative to building size.
Why ATPC Is Particularly Suitable
ATPC operates as a self-contained heating unit, requiring no connection to centralized heating or electrical infrastructure. Its autonomous operation makes it ideal for decentralized public facilities.
Typical Configuration Logic

Why ATPC Is a Practical Solution
Powered by its integrated photovoltaic panel, ATPC does not depend on grid electricity. This allows stable heating operation even in locations with limited infrastructure.
Typical Configuration Logic
Standalone installation on external walls
No grid power connection required
Automatic daily operation
System Value
Energy independence
Reduced reliance on fossil fuels
Long-term operational reliability
Greenhouses & Auxiliary Heating Applications
Application Challenge
Greenhouses often experience large temperature fluctuations during mornings and transitional seasons. Running fossil-fuel heaters continuously increases operating costs.
Why ATPC Adds Value
ATPC provides supplementary warm air during critical periods, reducing temperature drops and supporting plant growth without replacing existing systems.
Typical Configuration Logic
ATPC units supplying warm air during early hours
Combined with existing greenhouse ventilation
Automatic operation based on temperature thresholds
