SolarPLUS 2026: Why the program is ideal for demanding photovoltaic projects

SolarPLUS 2026 is one of the most relevant funding programs for urban photovoltaic projects.

It specifically addresses the biggest hurdles in existing buildings – statics, building integration, green roofs, facades and project preparation – and makes investments economical precisely where standard solutions reach their limits.

What is SolarPLUS 2026?

SolarPLUS 2026 is a funding program of the state of Berlin to accelerate the expansion of solar power on existing buildings .

The focus is not on simple standard systems, but on complex, building-integrated photovoltaic projects .

Funded by SolarPLUS:

Photovoltaic systems on apartment buildings and commercial properties
Green roof PV
Building-integrated photovoltaics (BIPV)
PV systems with electricity storage
Project preparation reports (structural analysis, roof condition, feasibility, concepts)

The goal of the SolarPLUS program

The goal is to implement feasible projects within existing buildings – not theoretical potential.

Why SolarPLUS 2026 makes particular sense

Many urban PV projects fail not because of the technology, but because of classic hurdles:

limited statics
existing roof greening
Historic preservation or design guidelines
high planning costs before the actual investment
economic disadvantages compared to standard rooftop PV

SolarPLUS 2026 addresses precisely this issue. The SolarPLUS program promotes:

Additional costs compared to standard PV , e.g. due to green roof or facade solutions
Preliminary investigations that reduce investment risks
Systemic solutions instead of minimal installations

This transforms a "difficult project" into an economically viable investment venture .

Why SolarPLUS 2026 is ideally suited for SOLYCO green roof solar systems

SOLYCO develops photovoltaic solutions for precisely those applications that SolarPLUS addresses:

urban existing buildings
high architectural requirements
Green roofs with simultaneous PV use
durable, sustainable system solutions
