What Should a Tesla Solar and Powerwall Proposal Include?

What should the proposal identify at a glance?

The first page should make the proposed system understandable without requiring the homeowner to decode model numbers or sales shorthand. It should identify the solar array, battery configuration, major electrical components, intended backup scope and the property information used to prepare the proposal.

Look for a concise summary that answers these questions:

• What solar and battery equipment is proposed?
• Which parts of the home are intended to remain powered during an outage?
• What electrical service and panel information was used?
• Which assumptions still require a site visit, utility confirmation or engineering review?
• What work is included, excluded or presented as an allowance?
• Which project documents are included?

A homeowner should be able to point to each answer in writing. If an important answer exists only in a conversation, ask for it to be added to the proposal or an attached scope document.

How should the equipment scope be written?

The equipment section should use specific product names and quantities. It should distinguish solar panels, Powerwall units, gateways, inverters, mounting hardware and any electrical equipment included in the proposed design. It should also identify substitutions that would require written approval.

A strong scope avoids vague bundles such as “solar plus battery package.” That phrase does not explain how many components are included, whether backup controls are part of the work or whether electrical changes are assumed. The goal is not technical clutter. The goal is a written record that can be checked against the later design and contract.

How should backup scope be described?

“Whole-home backup” should not stand alone as the complete description. The proposal should identify the design objective, the electrical service information available at the time and any loads that require further review. Large heating and cooling equipment, electric vehicle charging, well pumps, electric cooking and other substantial loads should be discussed rather than silently assumed.

Ask Solar Mike designs for homes with 200A and 400A service panels, while the final backup architecture is confirmed through site verification and engineering . A proposal should therefore distinguish the homeowner’s requested outcome from the design that has already been verified.

Look for a clear statement covering:

• The intended outage loads or backup area.
• Whether any circuits may be excluded or managed.
• The service-panel information used for the preliminary design.
• Items that could change after site verification.
• How a design change is documented.

Which drawings and site details should be included?

The proposal should say which drawings are included now and which will follow later. Depending on project stage, useful documents can include a roof layout, preliminary one-line diagram, battery location concept, equipment-location notes and a list of site conditions that still need verification.

Every Ask Solar Mike system design is produced and reviewed by a licensed engineering firm . The proposal should still explain whether the pages being reviewed are a preliminary sales layout or part of the later engineered design package. That distinction helps the homeowner understand which dimensions, locations and equipment choices are settled and which may change after field information is collected.

Photographs, measurements and equipment labels can also help connect the written scope to the home. Private property information should remain confined to the customer’s project documents rather than being reused publicly.

How should project responsibilities be divided?

The scope should identify responsibility for design, contracting, permitting coordination and project management . Ask Solar Mike handles those project functions . The proposal should also explain what information or access the homeowner must provide for the project.

Ask Solar Mike handles design, contracting, permitting coordination and project management . The written proposal should establish a clear project path and explain how changes are approved.

What warranty information belongs in the proposal ?

Ask Solar Mike projects include a 10-year workmanship warranty . The solar panels carry a 25-year manufacturer warranty . The battery carries a 10-year manufacturer warranty .

Keep workmanship coverage separate from panel and battery manufacturer coverage. The stated terms are 10 years for workmanship , 25 years for the panel manufacturer warranty and 10 years for the battery manufacturer warranty .

How can two proposals be compared fairly?

Create a side-by-side worksheet with one row for every material scope item. Compare equipment quantities, backup objectives, electrical work, design documents, site assumptions and exclusions. For Ask Solar Mike projects, design, contracting, permitting coordination and project management are handled by Ask Solar Mike . Compare the stated workmanship, panel and battery warranty terms separately .

Then mark each item as confirmed, preliminary, excluded or unanswered. This method exposes meaningful differences that can disappear when proposals are reduced to a single total. It also gives each company the same opportunity to clarify its scope in writing.

Which proposal gaps deserve clarification?

Request written clarification when the proposal relies on an undefined package, omits equipment quantities, describes a backup outcome without identifying the loads or leaves electrical work open-ended. These gaps do not automatically make a proposal unsuitable, but they prevent an informed comparison.

Also question documents that mix confirmed scope with possible upgrades without labeling the difference. An optional item should look optional. An allowance should be identified as an allowance. A condition requiring site verification should not read like a completed engineering decision.

What proposal details should be verified?

1. Confirm that the property and electrical-service information are correct.
2. Match every equipment name to a quantity.
3. Write down the requested backup outcome and the loads discussed.
4. Separate included work, exclusions, allowances and optional items.
5. Identify which drawings are preliminary and which require engineering.
6. Record the 10-year workmanship, 25-year panel manufacturer and 10-year battery manufacturer warranty terms .
7. Record that Ask Solar Mike manages design, contracting, permitting coordination and project management .
8. Ask for written answers to every blank field in your comparison worksheet.

The objective is not to produce the longest proposal. It is to create enough written detail that the homeowner, designer and project team are evaluating the same system.

What do homeowners commonly ask about proposal scope?

Can a proposal be brief and still be useful?

Yes. A short proposal can work when it is paired with clear attachments or incorporated scope documents. The complete package should identify equipment, backup intent, electrical assumptions, exclusions and unresolved conditions. For Ask Solar Mike projects, design, contracting, permitting coordination and project management are handled by Ask Solar Mike . The listed warranties are 10 years for workmanship, 25 years for panels and 10 years for the battery .

Should preliminary and engineered drawings look different?

The documents should clearly state their stage. A preliminary layout can communicate design intent, while the proposal should identify what remains subject to measurement, site verification or engineering review. Every Ask Solar Mike system design is produced and reviewed by a licensed engineering firm .

Does a battery name explain the backup design?

No. The battery model is only one part of the scope. The proposal should also describe the intended loads, available electrical information, control equipment and conditions that could change the final architecture.

What warranty terms does Ask Solar Mike list ?

Ask Solar Mike lists a 10-year workmanship warranty , a 25-year panel manufacturer warranty and a 10-year battery manufacturer warranty .

What if two proposals describe different backup outcomes?

Ask each company to map its proposed design to the same list of household loads and electrical conditions. Compare the written scope rather than assuming that similar equipment names create identical backup designs.
