Read a solar storm-hardening proposal without buying a slogan

Replace adjectives with a scope table

Create rows for the exact module, racking, attachments and fasteners, flashing, conductor supports, enclosures, drainage or flood provisions, equipment locations and shutdown information. For each row, record the model or detail, drawing or product source, who installs it and whether it is included in the base price. “Heavy duty,” “storm proof” and “hurricane rated” are not substitutes for those fields.

DOE notes that resilience measures can increase upfront cost and should be weighed against repair, downtime and longer-term operating consequences. That supports a transparent comparison; it does not establish a guaranteed payback or loss outcome for a particular home. [1]

Identify the property-specific design basis

List the service address, jurisdiction, site-risk information, roof geometry and construction, design criteria, proposed array position and field conditions still awaiting verification. Ask which professional or contractor is responsible for each calculation and permit submission. A generic certification or statewide marketing statement cannot close an unresolved roof assumption.

Map review, installation and substitution controls

Define the design checkpoints, permit-comment owner, final drawing release, product-substitution approval and field-discovery process. The installation scope should explain how approved hardware, clamp placement, fastener installation, conductor support, flashing and accessible equipment labels are checked. Ask what evidence becomes part of the homeowner closeout file.

A useful control is specific enough to test: who checks what, at which stage, against which document, and where the result is saved.

Compare cash price, financing and exclusions separately

Hold the installed equipment and work schedule constant, then compare the cash price and any financing terms. Break out roof repairs, structural work, electrical upgrades, permit-driven changes, batteries and optional resilience measures. Write down allowances and change-order triggers so a low opening number is not mistaken for the complete installed obligation.

Do not convert projected energy production, future utility inflation, a tax assumption, warranty term or insurance conversation into guaranteed monthly savings. Those are separate inputs with different owners and uncertainty.

Define the handoff after installation

Request the final equipment inventory, approved and as-built drawings, permit and inspection records, utility milestones, applicable warranties, monitoring access, safe shutdown instructions and service contacts. State whether post-storm inspection or maintenance is included, optional or outside scope. The owner should know which company handles roof, electrical, equipment and monitoring questions.

Use a decision rule before signing

Choose between proposals only after each one answers the same property, design, installed-scope and payment questions. A proposal with more explicit limits can be more trustworthy than one that promises an outcome it cannot document. Escalate unresolved structural, contract, tax, insurance or lending questions to the appropriate qualified party before authorization.
