The Solar Industry Continues to Evolve
2026 brings further changes for the photovoltaic industry. For solar installers, this means: those who stay informed and adapt in good time will secure competitive advantages. From new module technologies and changed framework conditions to innovative mounting solutions – here is an overview of the most important trends.
Trend 1: Larger Modules, Higher Performance
The trend towards more powerful modules continues. Modules with over 500 Wp in the residential sector are becoming standard. This has direct implications for installation:
- Fewer modules per system, but higher currents per string
- Adapted cable cross-sections required
- Fewer roof penetrations needed, but with more cables per penetration
Trend 2: Storage as a Standard Component
Battery storage will be part of virtually every new installation in 2026. For solar installers, this means additional expertise in electrical installation and an expanded value chain. DC-side cabling becomes more complex, making clean cable routing through the roof even more important.
Trend 3: Increased Efficiency on the Construction Site
In view of the shortage of skilled workers and rising personnel costs, efficiency on the construction site is coming into focus. Every minute saved counts. Products that can be installed without tools are gaining importance. Example: NEXCAPE roof penetrations made of TPU require neither tools nor MC4 disassembly and save up to 25 minutes per penetration.
Trend 4: Rising Quality Standards
End customers are becoming more demanding. They compare offers, read reviews, and pay attention to details. A professionally executed roof penetration is visible quality that builds trust. Makeshift solutions with construction foam or silicone are a thing of the past.
Trend 5: Sustainability in the Supply Chain
Made in Europe and short supply chains are increasingly becoming a selling point. Installers are also paying more attention to where their components come from. NEXCAPE roof penetrations are manufactured using 3D printing in Germany – without long transport routes and with flexible production without overstocking.
Trend 6: Balcony Power Plants as an Entry Point
The boom in balcony power plants brings new customer groups into contact with photovoltaics. Many then upgrade to a full-fledged rooftop system. For solar installers, this means additional business potential through consulting and retrofitting.
What do these trends mean for your material selection?
| Trend | Requirement for Roof Penetration |
| Larger Modules | Variants with more cable ducts (4 PV, 6 PV) |
| Storage Integration | Additional cables require flexible solutions |
| Efficiency on the Construction Site | Tool-free assembly, no MC4 removal |
| Quality Standard | Professional appearance, UV-resistant material |
| Sustainability | Made in Germany, short supply chains |
