This is an editorial shortlist rather than a premium-volume league table. We prioritized public evidence of renewable-energy specialization, solar-specific capability, construction-to-operations continuity, specialty-market access and familiarity with lender-driven project requirements.

A sponsor should still confirm the regulated servicing entity, proposed insurer panel, catastrophe capacity, claims resources and whether the actual broking team has handled solar projects of a comparable size and structure.

## FAQ About Solar Project Insurance Brokers for Solar and BESS

### What should a solar insurance broker understand about Solar and BESS?

The broker should understand the project structure, EPC and O&M contracts, financing requirements, catastrophe profile, replacement lead times and revenue model supporting the asset.

### Should DSU or business interruption be included?

Potentially. The appropriate limit and indemnity period should be tied to realistic delay, repair and revenue assumptions rather than a generic percentage of project value.

### Can an international broker service a local solar SPV?

That depends on licensing and admitted-policy rules. The sponsor should confirm the regulated servicing entity and whether local issuance, fronting or international capacity is required.
