To compare solar and battery warranties, Ask Solar Mike recommends separating coverage into workmanship, system-level protection, roof penetrations, manufacturer coverage, service labor, monitoring and the claim process . Do not compare only the longest number . Compare what failed, who responds, what labor is included, which exclusions apply and what written record you receive after installation .
This solar and battery warranty guide is for homeowners comparing written proposals before signing . Ask Solar Mike is a Utah Tesla solar and Powerwall 3 specialist . Use the worksheet below beside the actual documents, not as a substitute for them .

What should you compare besides the headline warranty term ?
A long term can look reassuring while leaving important questions unanswered . Identify the covered item and the event that activates coverage . A panel defect, lower panel output, installation error, roof leak and battery fault are different events that may be handled under different documents .
For every line of coverage, record these fields :
- Covered item: panel, inverter, battery, mounting, roof penetration, wiring or installed system .
- Covered event: defect, workmanship problem, damage, performance shortfall or another defined event .
- Term and start date: when coverage begins, how long it lasts and whether registration is required .
- Parts and labor: whether diagnosis, equipment, removal, shipping and reinstallation are addressed .
- Responsible contact: whom you contact first and who coordinates a claim .
- Exclusions: maintenance, roof work, unauthorized changes, transfer conditions and other written limits .
- Evidence: the signed agreement, manufacturer document, registration record and commissioning record .
Which warranty layers should appear as separate rows ?
Do not blend every form of coverage into one number . Use separate rows for workmanship, system-level coverage, roof penetrations, panels, batteries, inverters, service labor, monitoring and installation damage .
| Layer | What to verify | Ask Solar Mike term |
|---|---|---|
| Workmanship | What counts as incorrect installation, what is excluded and who coordinates correction . | Thirty-year workmanship coverage for correct installation . |
| System-level protection | Which installed components and labor events are included . | Ten-year bumper-to-bumper coverage from Ask Solar Mike . |
| Roof penetrations | Covered leak conditions, reporting steps and later roof-work exclusions . | Ten-year roof-penetration coverage . |
| Solar panels | Product defects, limited-power terms, degradation language and claim process . | Twenty-five-year panel manufacturer coverage . |
| Battery and integrated inverter | Capacity terms, operating limits, exclusions, registration and claim process . | Ten-year Tesla Powerwall 3 manufacturer coverage; its inverter is integrated under that Powerwall coverage . |
| Service labor and monitoring | Who diagnoses an issue, whether claim labor is included and how alerts become service cases . | No-cost labor on manufacturer warranty repairs for the program term—twenty-five years for solar and ten years for battery—plus continuous monitoring during that term . |
| Installation damage | How damage is documented, reported and repaired . | Insured repair of installation damage to the home . |
The table is a starting point . The signed agreement and applicable manufacturer documents control the details . Request those documents before signing, and mark an empty row “not provided” rather than assuming it is included .
How do workmanship and manufacturer coverage differ ?
Workmanship coverage addresses whether the system was installed correctly . Ask Solar Mike provides a thirty-year workmanship warranty for that purpose . Manufacturer coverage addresses the equipment maker’s written terms for a covered product . A manufacturer term alone does not answer who pays for diagnosis, removal, shipping or reinstallation .
This distinction matters with an integrated product . A Powerwall 3 system should not be shown with a separate twenty-five-year string-inverter term because the inverter is integrated into Powerwall 3 and covered under its ten-year manufacturer warranty . Match each warranty row to the equipment actually proposed .
What should Utah homeowners ask about service after installation ?
Ask who will provide the commissioning record, registration confirmation, monitoring access, ownership record, escalation contact and written change-order history . Ask Solar Mike provides a commissioning receipt, registration proof, monitoring handoff, homeowner ownership record, named service-escalation path and written change-order control on every project .
Verify the contractor identity shown in the agreement . Ask Solar Mike holds active Utah DOPL contractor license #14015846-5501 . Compare that name and number with the proposal, agreement and public license record before signing .
Which warning signs deserve a follow-up question ?
- One large warranty number appears without identifying whether it applies to workmanship, equipment, roof penetrations or labor .
- The coverage is summarized verbally, but the written document is unavailable .
- The equipment list and warranty list do not match .
- A manufacturer term appears without addressing diagnosis, removal, shipping or reinstallation .
- The roof-penetration language omits exclusions or later roof work .
- No one identifies the first service contact or post-commissioning records .
- Transfer, registration or maintenance conditions are left unexplained .
These points do not automatically make a proposal unacceptable . They are reasons to pause and obtain the missing language in writing .
How can you compare two proposals on one page ?
Create one column per proposal and one row per coverage layer . Copy the exact term, responsible contact, labor treatment, exclusions and required records . Attach the source document or page number to each answer .
Keep price and equipment scope on separate comparison pages . Review the Tesla solar panels guide for Utah homeowners, the Tesla Powerwall 3, Enphase and EG4 scope comparison, and the Tesla solar and Powerwall cost guide . This prevents a warranty headline from hiding a different design or price structure .
Frequently asked questions about solar and battery warranties ?
Is the longest warranty term automatically the strongest ?
No . Compare the covered failure, exclusions, labor, responsible contact, transfer rules and written claim steps .
Does panel coverage include labor ?
Do not assume it does . Ask Solar Mike’s program includes no-cost labor on manufacturer warranty repairs for the program term: twenty-five years for solar and ten years for battery .
What warranty applies to a Tesla Powerwall 3 inverter ?
Powerwall 3 integrates its inverter under the ten-year Tesla Powerwall 3 manufacturer warranty . It should not be represented as a separate twenty-five-year string-inverter warranty .
What records should I receive after installation ?
Ask Solar Mike provides a commissioning receipt, registration proof, monitoring handoff, ownership record, named escalation path and written change-order control .
Should verbal warranty explanations appear in the contract ?
Rely on written terms . If an explanation changes your decision, ask where it appears in the agreement or manufacturer document before signing .
