APVT-590 Air-Based PVT Module
Short Answer
The APVT-590 is an air-based photovoltaic-thermal module that generates 590 W of PV electricity under STC while recovering warm air from the back of the PV cells. It is best suited for roof-limited projects that need both electricity and low-temperature heat: agricultural drying, ventilation preheating, workshop heating support and hybrid building energy systems.
If your project only needs electricity, a standard PV module is usually simpler. If your project only needs warm air, a dedicated solar air collector may be more direct. The APVT-590 is strongest when both outputs are useful.
What Makes APVT-590 Different
A normal PV module converts part of sunlight into electricity. The remaining energy becomes heat and is usually released into the air. As PV cells heat up, electrical output can decline. The APVT-590 turns this problem into useful energy.
Behind the PV cells, an integrated air channel removes heat and delivers it as warm air through duct interfaces. This supports the PV side by reducing heat buildup while creating a second energy output.
This makes the product valuable where roof area is limited and the building has daytime heat demand:

Who Should Consider APVT-590?
The ideal buyer is not simply looking for a solar panel. The ideal buyer has a project where electricity and heat are both valuable. Strong-fit buyers include:
High-Value Applications
Agricultural Drying
Electricity powers fans and controls; warm air dries crops, herbs, seeds, fruit and biomass from one roof surface.
Ventilation Preheating
Preheat incoming fresh air during sunny periods for schools, offices, workshops and warehouses.
Space Heating Support
Renewable heat contribution for residential, light commercial or workshop spaces during sunny hours.
Roof-Limited Hybrid
When a roof can fit either PV or solar thermal but not both, APVT improves total energy per square meter.
The clear argument against PV-only design
It is not that APVT is simpler. It is that one physical surface can deliver more total useful energy per square meter when heat demand exists. For roof-limited projects with daytime warm-air needs, that energy-density argument is the deciding factor.
APVT-590 vs Standard PV Module
| Question | Standard PV Module | APVT-590 |
|---|---|---|
| Does it generate electricity? | Yes | Yes |
| Does it recover useful heat? | No | Yes |
| Is duct design required? | No | Yes |
| Best for electricity-only projects? | Yes | Not always |
| Good for roof-limited heat-plus-power projects? | Limited | Yes |
| Does it need antifreeze? | No | No |
Choose standard PV if heat cannot be used. Choose APVT-590 if warm air has real value in the project.
APVT-590 vs Dedicated Solar Air Collector
| Question | Solar Air Collector | APVT-590 |
|---|---|---|
| Main output | Warm air | Electricity plus warm air |
| Best for | Heat-only air applications | Hybrid heat and power applications |
| Electrical generation | No | Yes |
| Air duct needed | Yes | Yes |
| System simplicity | Usually simpler | More integrated but more complex |
If the customer only asks for drying heat, Soletks DVC or other solar air collector products may be a better fit. If the customer also wants PV generation from the same roof, APVT-590 becomes more attractive.
System Design: Two Sides, One Module
The APVT-590 should be designed as both a PV product and a thermal-air product. Electrical compliance alone is not enough for a successful PVT project.
Electrical Side
MC4 connectors and a maximum system voltage of 1500 V allow conventional PV string design. Confirm:
string length
inverter compatibility
current and voltage limits
cable sizing
DC protection devices
grounding
local electrical code
fire safety requirements
monitoring strategy
Air Side
The air side determines whether the recovered heat becomes useful. Key design points:
rated airflow 70-90 m3/h per module
twin Phi 100 mm duct interfaces
120 Pa static pressure rating
plan duct runs before installation
match fan to total pressure drop
insulate ducts in cold climates
handle condensation when preheating humid air
stop airflow when heat recovery is not beneficial
Engineering Evaluation Method
A PVT project should be evaluated by combined useful energy:
The recovered heat has value only if the building or process can use it. A project with no daytime heat demand should not force a PVT solution. Useful questions before sizing:
How many hours per day can warm air be used?
What is the required airflow?
What outlet temperature is useful?
What fuel or electricity does the heat replace?
Is the duct path short and practical?
Is the roof area limited?
Can the electrical output be consumed or exported?
Procurement Checklist
Before requesting a quotation, prepare:

- target application: drying, HVAC, heating or mixed
- required airflow and temperature range
- recirculated air or fresh outdoor air
- duct distance from modules to load
- electrical system voltage and inverter concept
- mounting structure requirements
- snow and wind load requirements
- annual operating schedule
- preferred delivery terms
- certification or documentation requirements
Why Choose Soletks APVT-590?
Soletks develops solar thermal, PVT and hybrid energy products for commercial, agricultural and industrial applications. The APVT-590 is designed for customers who want a factory-direct hybrid solar module rather than a generic PV panel.
It gives distributors and EPC contractors a more specialized product for projects where PV-only systems do not capture all available energy value. Explore the broader range on the PVT solar panel and PVT hybrid energy pages.
FAQ
What is APVT-590?
APVT-590 is an air-based photovoltaic-thermal module. It produces 590 W of PV electricity and recovers warm air from behind the PV cells.
Does APVT-590 use water?
No. The thermal side uses air. There is no liquid loop and no antifreeze requirement.
What is the airflow per module?
The rated airflow range is 70-90 m3/h per module. Final airflow depends on outlet temperature target and duct pressure drop.
Is APVT-590 better than PV?
It is better only when the project can use both electricity and warm air. For electricity-only projects, standard PV is usually simpler.
Can APVT-590 be used in cold climates?
Yes. The operating temperature range is published as -40 to 70 C. Cold-climate projects still need duct insulation and condensation control.
What applications are not ideal?
Projects with no useful heat demand, no duct path or no daytime warm-air use are usually not ideal for APVT. In those cases, PV-only or a dedicated thermal system may be better.
