A plan to outfit the Waiau Gardens Kai B townhome complex in Pearl City with solar panels and battery storage is now in jeopardy after Hawaii legislators imposed a retroactive $40 million cap on the state’s solar tax credit program. The cap, announced on May 8, could strip away promised incentives for projects already under way, raising doubts about the state’s ability to meet its 100% renewable electtricity target by 2045.

May 8 cap limits solar tax credits to $40 million

The Hawaii legislature voted on May 8 to slash the annual solar tax credit pool from roughly $100 million to $40 million,and applied the reduction retroactively to projects slated for 2026. as the report notes, the change “made it retroactive to 2026,jeopardizing projects that had already commenced based on the promise of those credits.” This abrupt policy shift means developers who counted on the larger credit now face a shortfall that could render their financial models untenable.

Larry Veray’s Waiau Gardens Kai B solar plan

Larry Veray, president of the homeowners association at the Waiau Gardens Kai B complex, had secured a financing structure that relied on the full tax credit to keep monthly fees flat for residents. The initiative was designed to deliver cheaper, cleaner electricity without raising HOA dues, a model that could have become a template for other multi‑family developments across the islands. according to the source, Veray’s plan was “in jeopardy after lawmakers imposed a retroactive cap,” highlighting how a single policy decision can ripple through local communities.

Hundreds of projects face funding uncertinty

The impact extends far beyond Pearl City. Industry groups estimate that “hundreds of similar commercial and industrial solar projects across the state” now confront financing gaps. Many of these projects were already under construction or had secured contracts based on the expectation of a stable credit environment. The uncertainty threatens to stall new capacity additions at a time when Hawaii’s Renewable Portfolio Standard demands rapid expansion.

Industry calls for a special legislative session

Solar developers and trade associations are urging the state legislature to convene a special session to amend the retroactive provision. They argue that the cap “conflicts with Hawaii's law mandating 100% renewable electricity by 2045,” and that a swift correction is needed to preserve investor confidence. As the article reports, the industry is lobbying for an exemption or a phased implementation that would honor commitments already made.

Will lawmakers reverse the retroactive provision?

Key unanswered questions remain: Will the legislature reopen the tax credit rules before the next fiscal cycle? Who will bear the cost if the cap stays in place—developers, homeowners, or ratepayers? The source notes that the retroactive element is the most contentious, but it does not provide details on any forthcoming compromise.
