Sunrun Inc. (NASDAQ:RUN) saw a share price increase of 11.35% on Monday, closing at $15.50. New tax credit rules for solar and wind energy projects, less restrictive than anticipated, boosted investor confidence. Companies now only need to show physical project construction started before July 5, 2026, rather than spend 5% of project costs.

The updated guidelines for tax credits focus on the nature of work done, not the amount or cost. Developers previously had to prove they spent at least 5% of the total project cost to qualify. The new rules are part of the One Big Beautiful Bill Act, which phases out clean energy tax credits after 2027 but provides exceptions for projects starting by July 5, 2026.
