Commercial PV
Operating Commercial PV Projects
more profitable, efficient, and future-proof
Optimize your PV system on commercial buildings.
opti.node brings these tasks together as a central software and data platform, regardless of whether your project is structured as tenant-generated electricity, a community building energy supply, or an onsite PPA.

For our customers, energy is simply worth it

From Roof Space to Revenue Stream
Today, the return on a rooftop solar system depends more on commercial management than on the technology itself. Output curtailment, negative price windows, and increasing operator obligations have a direct impact on revenue. opti.node automates energy-related calculations, tracks contracts and deadlines, and provides a clear overview of the profitability of each property—whether it’s the first project or a growing portfolio.
Understanding the True Cost of PV Curtailment
Grid operators are increasingly curtailing rooftop systems as well, in some cases completely at the inverter level. If on-site consumption drops to zero, more expensive grid power becomes necessary, and the projected return on investment comes under pressure. Compensation claims can only be substantiated with reliable data. In opti.node, generation, sales, and curtailment data are consolidated into a single database. This makes lost output traceable, quantifies the economic damage, and highlights every revenue stream that contributes to the project.
Getting Projects to the Grid Faster
The decision on which supply model is economically viable is made early on. The metering concept, tenant structure, system size, and grid connection situation determine whether tenant electricity, community building supply, or an on-site PPA is the appropriate arrangement. Subsidies also depend on these factors: Systems commissioned on or after May 16, 2024, can claim the tenant electricity subsidy even for commercial properties, over a 20-year subsidy period. opti.node guides you through these decisions, helps verify the requirements, and prevents mistakes that could prove costly during later operation.
Billing and operator obligations without the extra effort
Handle your ongoing commercial operations automatically in opti.node Invoices, reports, and deadlines are managed reliably, without you needing to become an energy market expert.
Guarantees of origin
Guarantees of origin for on-site energy supplies
With node.energy, operators can officially identify tenant electricity as green electricity for the first time. Consumers receive transparent evidence of the origin of the delivered green electricity.
Efficient and transparent certification of solar energy
Verifiable green energy through guarantees of origin. In addition to automated billing, opti.node also offers you certified guarantees of origin (HKN) for tenant electricity and on-site PPA deliveries to consumers.
