Most solar contracts include a production guarantee — a written commitment from your installer about how much energy the system will produce each year. The terms of that guarantee vary significantly between installers and proposals. The review flags the clauses that most affect your ability to enforce it later.
What OwlWatt checks in a proposal
- ✓Production guarantee — is there one, and what does it actually promise? Some proposals name a kWh figure; others reference "system performance" without specifying a measurement method.
- ✓Measurement period — production guarantees are measured annually in most residential contracts. Some use a rolling 12-month window; others use a fixed calendar year. The difference affects when and how you can make a claim.
- ✓Exclusion clauses — read your specific contract carefully. Common exclusions cover production losses from shading added after install, equipment failure caused by the homeowner, and utility outages. OwlWatt flags any exclusion that is broader than standard industry terms.
- ✓Remedy terms — what does the installer owe you if the system underperforms? Cash payment, additional panels, or "reasonable efforts" to correct? The remedy clause determines whether the guarantee has practical value.
- ✓Monitoring access — does the contract specify that the installer controls the monitoring data? If so, you may need an independent data source to document a future claim.
Why this matters before you sign
Once you sign, the terms are fixed. Negotiating a stronger guarantee after installation is rarely possible — the installer has already completed the work. Identifying a weak or missing guarantee clause before signing gives you the opportunity to ask for a revision or walk away.
OwlWatt does not recommend installers or advise you on whether a specific proposal is worth signing. The review surfaces what the contract says and flags where the terms differ from common industry standards. What you do with that information is your decision.
Already installed?
If your system is already in the ground, the pre-sign review does not apply. OwlWatt's main service tracks your production against your existing guarantee on an ongoing basis and documents shortfalls when they occur.
