Your solar panels are running at full capacity, the sun is shining, and yet the return is disappointing. On the sunniest days you export power at rock-bottom or even negative prices. Sound familiar? For businesses with a large rooftop array, that is the new reality. The question is no longer whether to install solar panels, but how to get more out of what you generate. The answer lies in combining a smart grid with solar panels. This article is part of our smart grid pillar and shows how to move from passive to smart feed-in.
Feed-in revenues keep falling, and on the sunniest days they collapse entirely. Margins are vanishing, but the solution is not more panels.
- The Dutch net-metering scheme ends on 1 January 2027. Exported power is becoming structurally less valuable across Europe.
- During solar peaks, electricity prices regularly drop below zero. You export your most expensive generation at the worst possible moment.
- Grid congestion forces network operators to curtail PV output more and more often: lost revenue you never recover.
- With a smart grid you reorder the priority: self-consume first, then store, then charge, and only feed in last, at the highest price.
- Energy-intensive businesses achieve up to 60 % lower energy costs and up to 50 % less CO₂ with Tibo EMS.
Not more panels, but smarter control. That is where the gains are.
Why feed-in revenues keep shrinking
For years, feeding in was straightforward: whatever you did not consume went to the grid, and you received a decent compensation in return. That era is ending. Three developments are eroding the value of passive feed-in.
Net-metering and export-tariff schemes are being phased out across Europe. Exported power earns less every year, while self-consumed power becomes more valuable by the day.
On sunny days the entire country generates at once. Supply floods the market, prices drop and regularly turn negative. You end up exporting your peak generation at the worst possible moment.
The grid is full. Grid congestion increasingly forces network operators to curtail solar output. That curtailment means lost revenue: your panels are simply not allowed to deliver.
The result is frustrating. Your most expensive generated electricity is exported at the lowest tariff, or you cannot export it at all. Smarter feed-in therefore starts with a different question: not how much you generate, but when you deploy that power.
Passive versus smart feed-in
Before investing in a battery or a controller, it pays to understand where the value sits. The difference between passive and smart feed-in determines how much value you extract from the same panels.
The bottom line: with passive feed-in you are at the mercy of the grid and the market. With smart feed-in you flip the script and choose the moment.
What a smart grid does for your solar panels
A smart grid is a network in which generation, consumption, storage and software communicate continuously. Instead of sending power blindly to the grid, every kilowatt-hour is deployed at the right moment and in the right place. For your solar panels this creates a smart priority sequence.
This way you prevent peak demand and grid congestion on your own connection, and you get more from the same installation.
Smarter feed-in with Tibo EMS
Managing that smart priority sequence manually is impossible: prices, weather and consumption change every minute. That is what Tibo’s energy management system was built for. She works independently of your hardware and connects to your existing panels, batteries and charge points, without replacing anything.
Every five minutes she recalculates a 48-hour control schedule and selects the smartest decision per asset: self-consume, store, charge or feed in. She factors in dynamic market prices (EPEX), so you export when the price peaks and store when it drops. No fixed rules, but continuous optimisation based on real-time data.
The results are not theoretical. Energy-intensive businesses achieve up to 60 % lower energy costs and up to 50 % less CO₂ by maximising self-consumption of their own renewable power. At a client such as Montea, which operates multiple sites with panels and batteries, the system coordinates generation, storage and consumption across the entire site, with measurably lower costs as a result.
Discover what smarter feed-in delivers for you
Curious how much you would save by moving beyond passive feed-in? With the Tibo System Simulator we build a digital twin of your situation together with a Tibo partner, based on your own consumption data. That way you see, before any investment, exactly what a smart grid delivers for your solar panels in terms of cost, CO₂ and flexibility. Request a simulation.
