Start with the source records
Find the actual guarantee rather than assuming a sales projection is the guarantee. Identify the guaranteed amount, measurement period, degradation assumption, exclusions, notice procedure, and remedy described in the document. Keep the page with definitions and attachments.
Compare the details
Compare actual and promised kWh for the same period. Check whether the system was authorized to operate for the full period and whether monitoring data is complete. Record service outages and shading changes. Utility dollars alone do not provide a like-for-like production comparison.
Turn the record into useful questions
Use the shortfall tool to organize arithmetic, then read the contractual procedure. A percentage difference is not automatically the compensation owed. A guarantee may use a different reconciliation period or formula, and other issues may require separate review.
Build the review file
Signed installation and finance agreements, lease or PPA; the proposal and disclosures; signing records; utility bills and production reports; photos and inspections; messages and complaint responses; permit, PTO, warranty and account notices.
Common mistakes to avoid
Do not delete original messages, crop away dates, or send only the signature page. Do not assume a complaint stops a payment obligation or a deadline. Before accepting a repair, buyout, or release, identify what it changes. You can contact us even if records are incomplete; tell us what is missing.
Questions homeowners ask
Do I need every document before contacting you?
No. Start with what happened and what records you have. The team can explain what additional material may be useful and how to share it securely.
Does this problem mean I can cancel or stop paying?
This page cannot determine that. The agreements, parties, evidence, and applicable rules need individual review. Do not change payments based on a calculator or this guide.
What happens after a free review request?
Our intake team reviews the inquiry and contacts you using the details supplied. Any retained investigation or representation requires a separate agreement describing scope and fees. This is not an emergency response service.
