Sunmaxx PX-1 PVT Module – One System, Dual Energy: Power and Heat
The PX-1 from Sunmaxx is the first industrially manufactured PVT module of its kind to combine advanced thermal management technology from the automotive sector with cutting-edge solar cell technology. It merges photovoltaics and solar thermal energy into one compact, high-performance system. The PX-1 simultaneously generates electricity and heat – efficiently, quietly, and space-saving. Designed for pitched and flat roofs, façades, and open spaces in various orientations, it is a future-proof solution for zero-emission heating, cooling, and powering brine-to-water heat pumps.
Key Advantages at a Glance:
- Photovoltaics + Solar Thermal in one module – maximum roof utilization and efficiency
- Ultra-light weight (< 30 kg) – suitable for all PV-compatible roofs
- Easy installation – fits all standard PV mounting systems
- Silent operation – no additional outdoor unit required
- Cost-Efficient – an alternative to air-source heat pumps + PV or geothermal systems
- Compatible with all common brine-to-water heat pumps
PX-1 PVT Module – 4× More Energy per m²
Unlike conventional systems, the PX-1 PVT module from Sunmaxx draws on not just one, but two renewable energy sources: solar radiation and ambient air. On the front side, it generates electricity – just like a standard PV module. On the back, a specially developed, ultra-lightweight aluminum heat exchanger extracts thermal energy from the module and transfers it via a hydraulic system to a brine-to-water heat pump, where it is used for heat generation.
Technological Highlights:
- 80% overall efficiency (electrical + thermal)
- Up to 4× higher energy yield compared to conventional PV
- Two energy sources in one system – no additional space required
- Combines electricity generation with source heat for brine heat pumps
Sunmaxx' PX-1 PVT module is a hybrid system with an overall efficiency of more than 80 percent. Compared to conventional PV modules, it can yield up to four times more energy – a decisive advantage, especially in densely built-up areas where roof and façade space is limited.
PVT Heating vs. Air-Source Heat Pumps – More Efficient, More Affordable
A conventional heating system combining a PV system and an air-to-water heat pump typically requires three components – including an outdoor unit. The PX-1 module reduces this to just two: a PVT plant and a brine-to-water heat pump. This saves space, simplifies installation, and eliminates noise emissions.
A PX-1 system scores particularly well in densely populated and noise-sensitive regions thanks to its silent operation - there is no outdoor unit required. Despite similar investment costs, the combination of PX-1 and brine heat pump offers greater efficiency and a n extended service life.
Your Benefits at a Glance:
- No outdoor unit required – more space and completely silent operation
- Same investment as air-source heat pump + PV, but significantly lower operating costs
- Higher efficiency and extended lifespan thanks to module cooling
- Ideal for urban areas and renovations subject to noise restrictions
Suitable for Single-family Homes Even Without Geothermal Energy
A PVT system with PX-1 modules can operate a brine-to-water heat pump efficiently and without the need for geothermal probes or collectors. For most single-family homes, the available roof area is sufficient to provide the required source heat – even at lower subzero temperatures.
There are costs for drilling, surveys, and other geothermal site developments. For larger applications – such as multi-family buildings, industrial facilities, and low-temperature district heating networks – a bivalent operation with additional energy sources is recommended. This approach can significantly reduce the costs of energy-efficient renovations and new installations.
Advantages of a PX-1 PVT System Specifically for Single-Family Homes:
- Monovalent operation without the need for an additional heat source
- Cost savings in planning and installation
- No issues with environmental regulations, e.g., noise emissions or water protection areas
- Can also be mounted vertically, for example on walls or façades
Note:
Sample calculation for single-family home with a heating demand of 24 MWh/year. Calculated with 20 modules PV/PVT (corresponds to 40 m2 or 8.6 kWpel), combined with 10 kW heat pump. 34 ct€/kWh electricity costs, 7 ct€/kWh feed-in tariff, 30 years lifetime. PV/PVT without VAT, rest including VAT (in accordance with current legislation).
The PX-1 PVT Module – Combining Photovoltaics and Solar Thermal for Maximum Benefits
The PX-1 combines the best of two worlds: cutting-edge photovoltaic power generation with solar thermal heat capture. Developed by experts in solar and thermal technologies, it is optimized for PV mounting systems, delivering maximum efficiency alongside user-friendly design.
Thanks to standardized dimensions and clever plug-and-play connectors, the PX-1 PVT module can be easily integrated into existing PV mounting systems. Industrial mass production ensures consistently high quality while keeping system costs attractive.
Technical Highlights:
- Electricity and heat from a single module – space-saving and high-performance
- Compatible with all common PV mounting systems
- Fast and secure installation with simple plug-and-play connector technology
- Industrial mass production – high quality at attractive module prices
Compatible With a Wide Variety of Brine Heat Pump Models and Providers
The PX-1 PVT module can be combined with almost all standard brine heat pumps - regardless of the manufacturer. This makes it ideal for new builds, energy-efficient renovations and hybrid heating systems. Integration is simply carried out by your responsible installation company and Sunmaxx specialist partner.
Cross-manufacturer compatibility – with a guarantee of flexibility, future-proofing and low energy costs in the long term.
Increased PV Output Thanks to Module Cooling
An additional advantage of the PX-1 lies in its continuous module cooling. The heat exchanger installed on the back safely dissipates excess heat directly into the heating system. This keeps the PV cells within their optimal temperature range, minimizing performance loss even during summer. The result: higher electricity yields, extended module lifespan, and maximum system efficiency – all automatically.
*Note:
Conversion factor given for natural gas; in reality it is much higher, bc. of additional leakage during exploration/transport leading to CH4 emission (80 x stronger climate gas than CO2).
Benefits of Cooling in Sunmaxx PX-1 Modules:
- 5 to 10% higher electricity yield thanks to consistently lower cell temperatures
- Reduced performance loss on hot days compared to conventional PV modules
- Longer lifespan due to thermally stable operating conditions
