The final day should not be only a payment and a quick demonstration. A solar system is a long-lived electrical asset, and the handover creates the record that explains what was installed, how it is protected, and how the owner can request service later.
Match the installed equipment to the quotation
Compare panel model and quantity, inverter model, battery model and capacity, breakers, surge protection, mounting hardware, monitoring devices, and cable routes with the agreed scope. Record serial numbers and take clear photos of labels. If a component was substituted, request the reason and updated documentation. For the next planning step, see solar panel cleaning and maintenance guide. For a personalized system check, use the CalcSolarPH solar calculator.
Inspect workmanship without opening live equipment
Look for secure mounting, organized cable management, weather protection, clear labels, accessible disconnects, sealed roof penetrations, and an unobstructed inverter area. Do not remove covers or touch conductors. Visible workmanship checks should complement, not replace, professional electrical tests. For the next planning step, see solar monitoring guide.
Request the commissioning record
The record should identify the system date, equipment, test results, protective-device checks, operating mode, and any outstanding work. For hybrid systems, confirm what happens during a grid outage, how non-backed-up circuits behave, and how the battery is protected from over-discharge.
Confirm the monitoring handover
The owner should receive the correct app or portal account, device pairing instructions, Wi-Fi requirements, and guidance on normal daily production. Ask what data is retained if the internet fails. A monitoring dashboard is useful, but the system should still operate safely when connectivity is interrupted.
Understand warranty boundaries
Separate product warranty, workmanship warranty, roof waterproofing responsibility, and service response terms. Ask what evidence is required for a claim, which actions could void coverage, and whether batteries have different throughput or cycle conditions from the inverter and panels. For the next planning step, see solar system maintenance guide.
Keep a homeowner system file
Store the documents digitally and in a physical folder. Include the final diagram, photos of concealed cable routes, serial numbers, invoices, warranties, test results, maintenance notes, and support contacts. Update the file when equipment is replaced or the roof is modified.
Do not rush unresolved items
If a safety label, document, monitoring account, or corrective work is incomplete, list it in writing before final acceptance. Clear written records protect both parties and make later troubleshooting much faster. For the next planning step, see solar warranty records guide.
Frequently Asked Questions
What documents should a solar installer turn over?
Request the final equipment list, single-line diagram, manuals, warranty certificates, commissioning results, protection settings where appropriate, monitoring credentials, and maintenance instructions.
Should I accept a system if the monitoring app is not working?
Ask the installer to document the issue and provide a clear resolution date. Monitoring is not the only proof of production, but missing access makes it harder to detect faults and verify performance.
Who should perform electrical tests?
Testing and energization should be performed by a qualified professional using appropriate instruments and procedures. Homeowners should not open energized equipment to repeat tests themselves.
For a first estimate, use the CalcSolarPH solar calculator, then compare the result with your actual loads and roof conditions. You can also browse the solar products catalog before speaking with an installer.

Utility, ERC, and Zone Handover Checkpoints
A Philippine handover folder should state whether the project is residential, commercial, grid-tied, backup-capable, zero-export, or net-metered. For a Meralco customer, the installer should identify the current utility application and inspection path. For an installation above the ordinary net-metering ceiling, the project may require a different DER or zero-export treatment. For PEZA sites, include the zone administrator, designated distribution utility, facility owner, and any project-registration or commercial-energy documents in the responsibility matrix.
The PEZA–UGEP announcement describes solar projects in Cavite and Baguio economic zones where power may be generated and sold to end consumers through designated distribution utilities. That is a zone-level commercial example, not a generic residential approval shortcut. See PEZA’s official announcement.
