Across Europe, the economics of solar-only systems are undergoing a structural shift. Negative electricity prices, stricter grid export limitations, and increasing volatility in wholesale power markets are reducing the predictability of solar revenues.
According to industry research from organizations such as the International Energy Agency (IEA) and Fraunhofer ISE, curtailment events and price fluctuations are becoming more frequent in markets such as Germany, the Netherlands, Spain, and Italy.
In this environment, exporting surplus solar energy to the grid is no longer a reliable value strategy. Energy must be managed, not simply generated.
