Questions homeowners ask
How can I compare Wisconsin solar proposals on the same basis?
DATCP recommends multiple estimates for the same work and a site visit rather than a telephone-only estimate. Ask each bidder to identify its actual equipment and included work; an unusually low quote needs explanation.

What should I ask about projected savings and monthly payments?
DATCP describes savings as estimates affected by weather, usage and future electricity prices. Its finance questions include total cost, down payment, monthly payments and increases. Keep the actual payment schedule beside the savings assumptions.

Does a solar proposal settle Wisconsin license and permit questions?
No. DATCP says some work may require a licensed contractor, such as an electrician, and directs consumers to DSPS and the specific municipality for applicable requirements. Identify the actual work and responsible businesses before relying on a proposal.

How should an important verbal promise be documented?
DATCP recommends putting the promise in the written contract and warns that fine print may exclude representations outside it. Ask for the exact written obligation, responsible business and conditions; a sales conversation is not a substitute for a reviewable agreement.

What should I do before an electronic signature?
DATCP says an electronic signature agrees to the contract terms. If the electronic pad is hard to read, ask for a written copy. Read the complete agreement and retain the signed copy; seek advice about provisions you do not understand.

What should I prepare before a DATCP complaint?
The agency advises contacting the seller and then a supervisor, manager or owner if needed, clearly stating the requested solution. For a complaint, retain the problem history, purchase date and location, copies of documents and contact information.

Can DATCP force the solar business to resolve my complaint?
Its complaint page says it cannot force resolution. Staff contact the business after reviewing the complaint. Use the agency’s current complaint categories and instructions; submission is not a refund, contract cancellation or decision on disputed rights.

Does a survey or inspection approve the contract?
No. A technical assessment answers its agreed evidence questions and has access limitations. Contract duties, payment schedules and dispute processes remain separate. Ask Solar Survey AI about available survey or inspection scope and compensation or referral relationships before calling a review independent. Homeowner monitoring connections and planned remote diagnosis remain coming soon.
Your decision checklist
- Compare identical equipment and work scopes across written proposals.
- Identify the contracting business and actual licensed-work participants.
- Keep the payment schedule beside the stated savings assumptions.
- Request complete readable agreements before signing.
- Match important sales promises to the actual written duties.
- Retain signed documents and a dated communication history privately.
- Confirm municipality, utility and program requirements separately.

Compare the proposal and keep the service history
| Separate field | Record to retain |
|---|---|
| Scope | Equipment, included work, exclusions and responsible business |
| Financial assumptions | Payment schedule, stated savings basis and unresolved questions |
| Written promise | Exact obligation, conditions and responsible contracting party |
| Signature record | Complete signed agreement and retained version |
| Service history | Dated issue, contact, response and requested solution |
| Routing | Actual permit, utility, program or consumer-agency question |
Example: two proposals have different totals, but one includes a battery and the other excludes electrical work. The homeowner marks those scope differences before treating the lower total as a better offer. The organizer does not decide which equipment or financing is suitable.
Example: a salesperson promises a particular service response, but the homeowner cannot find that duty in the proposed agreement. They request the written obligation and responsible business before signing. If a later problem arises, they keep dated communications and state the solution requested through the appropriate channel.
The advantage of a private comparison is that missing scope, unsupported promises and unanswered service questions become easier to identify. The tradeoff is the time needed to gather comparable records, and the worksheet cannot establish legal enforceability, certify a contractor or guarantee recovery. Avoid publishing signatures, account identifiers and private financial documents in public reviews.
