Solar corporate funding rises 45% to $25.1B through three quarters

· Energy

Total corporate funding into the solar sector reached $25.1 billion through the first three quarters of 2026, up 45% year on year, according to a report from Mercom Capital Group. The figure covers venture capital, public market financing and debt financing, and points to renewed investor appetite for solar businesses even as panel manufacturers face pressure. The report gives the industry a single benchmark for capital flows into solar at a time when financing conditions and policy support vary widely by market. Corporate funding is a leading indicator for project pipelines and manufacturing capacity, so a 45% increase signals that capital is returning to the sector rather than staying on the sidelines.

Why it matters：Funding is the gating factor for solar manufacturing and project buildout, so a sharp rebound in capital flows affects developers, equipment makers and investors globally.
