HOME SOLAR INSTALLATION · CEBU
We assess your roof, design the system from your own bills, handle the permits, install and test it, file your net metering and support you after handover. Deye hybrid inverters, 620 W N-type TOPCon panels and 5.12 kWh LiFePO4 batteries, priced line by line.
Choose an installer who visits before fixing the price, sizes the system from your bills, itemises the quote with model numbers you can check, has the electrical plans signed and sealed by a Professional Electrical Engineer (RA 7920 requires it), secures the LGU electrical permit, tests and configures the system, and files net metering with VECO, MECO or your CEBECO co-op.
Cheap Solar Cebu’s process covers each of those steps for homes across Cebu; permits and net-metering paperwork are in the itemised estimate. We don’t promise an installation time before seeing your roof: the schedule is confirmed in your proposal.
CHOOSING AN INSTALLER
Seven checks to put to any installer, including us. For comparing two quotations line by line, use the quote comparison guide, or browse all Cebu solar guides.
Roof structure, shade and your main panel can’t be judged from a satellite image or a phone call.
Our processEvery quotation follows a site assessment. The online estimate is a starting point, not the contract price.
An oversized system costs more than it saves; an undersized one leaves savings unclaimed.
Our processPanels are counted from your yearly kWh and the roof space we measure; batteries from your evening use and the circuits you want on.
Model numbers let you read the datasheets and compare like with like.
Our processThe Deye inverter model, the panels, the battery, mounting and installation are each a priced line.
RA 7920 requires electrical plans signed and sealed by a Professional Electrical Engineer, and a permit, before any installation.
Our processPermit paperwork is part of the itemised estimate. Ask to see the electrical plans, signed and sealed by the Professional Electrical Engineer, before work starts.
Isolators, surge protection, breakers and earthing are what make a system safe to live with.
Our processAsk for the protection fitted to be listed in your proposal. We don’t claim anything that isn’t fitted.
A system not configured for your battery and the 60 Hz grid isn’t finished, however neat the roof looks.
Our processWe test, configure and set up monitoring before handover, then walk you through it.
Export credits start only after the utility approves. Support terms belong on paper, not in a chat.

From first call to after-sales
01 / 07Chapter 01
Before anyone visits
Tell us your usual monthly bill, your utility and your priority: lower bills, brownout backup, or both. The calculator on this page gives you an itemised first estimate in pesos before you share any contact details.
The online estimate is instant. When you request a quote, we call to agree a visit date.
A first estimate and a booked visit, with no obligation.
Chapter 02
On site · roof, wiring, space
Every roof face and its pitch, the purlins or rafters under the sheets, shade from trees and neighbours through the day, the main breaker and its spare ways, the earthing, and the wall where the inverter and battery would live. We also note the meter, the cable route, your Wi-Fi signal and the transformer that limits how much solar the utility can accept.
Booked at a time you choose. Use the checklist below to prepare.
A site record the design and the final price are built on.
Chapter 03
On paper · sized to your home
Panels are counted from your yearly kWh and the roof space we measured, keeping clear of edges and vents. The inverter is matched to the array and your peak load; the battery to your backup circuits. Your proposal shows the roof layout and every line item, with the Deye inverter model named, and a single-line diagram is drawn for your house.
Philippine law then requires the electrical plans to be signed and sealed by a Professional Electrical Engineer, and an LGU electrical permit, before installation starts.
Legal limit: the LGU acts on the electrical permit within 3 working days of complete documents and payment (JMC 001 s.2026).
An approved design, and a permit before work starts.
Chapter 04
On the roof · the part that holds
In strong winds, rooftop systems tend to fail at clamps and fasteners rather than at the panels. So rails are fixed through the roof sheet into the purlins or rafters with sealed fasteners and kept back from the edges, and panel clamps go only where the panel maker’s manual allows, tightened to the specified torque.
Installation days depend on the roof and the system size. We confirm the schedule in your proposal.
A mounting structure tied into your roof’s frame.
Chapter 05
On the wall · inverter, battery, protection
Panels are wired in strings to the Deye hybrid inverter through a DC isolator and surge protection. The battery connects through its own DC breaker, and the circuits you chose move to a backup sub-panel. The inverter goes on a shaded, ventilated wall above flood level, because it derates above 45 °C.
Expect one scheduled power interruption while we connect to your main panel; we agree the time with you.
Hardware installed, labelled and ready to test.
Chapter 06
Switch-on · tests, settings, paperwork
Before switch-on we check polarity, string voltages, earthing and every breaker. The inverter is set for the Philippine 60 Hz grid and your battery, the backup changeover is tested by cutting the grid supply, and monitoring is set up on your Wi-Fi. Grid-connected operation waits for the utility’s approval; the CFEI and your net-metering application go in next.
Legal limits: CFEI within 7 working days (3 while EO 110 is in force); utility processing within 20 working days, or 10 under EO 110. The impact study and the utility’s testing are free.
A tested system, and export credits once the bidirectional meter is in.
Chapter 07
Evening one, and the years after
At handover we walk you through the monitoring app, show what the backup sub-panel covers in a brownout and what it doesn’t, and hand over your documents: copies of the electrical plans, permit and CFEI copies, net-metering papers, datasheets, serial numbers and warranty documents.
After-sales support continues once the system is running. Its terms, and every warranty term, are confirmed in your proposal.

BEFORE THE VISIT
Tick what you have, choose what must stay on in a brownout, then print the list or send it with your quote request. Nothing leaves this page unless you ask.
Site-visit preparation checklist
Printable · nothing is sent unless you request a quoteSYSTEM DESIGN
A single-line diagram like this one is drawn for your house. The electrical plans filed for your permit are signed and sealed by a Professional Electrical Engineer, as RA 7920 requires.
We size from kWh, not the peso total, because Cebu rates moved by ₱0.50–₱1.00/kWh in a typical month in 2025–26. A system aimed at lower bills covers about 70% of a year’s use at a cautious 1,350 kWh per kWp; a backup system covers more and adds batteries for the evening.
Each 620 W panel takes about 2.7 m². The layout works around vents, edges and shade, and the inverter is normally chosen with room for at least 20% more panels than we install, so the system can grow.
In a brownout the grid-tied side must shut down. Only circuits on the inverter’s backup port stay on, so we agree them with you. One battery gives about 7 hours of essentials; with an aircon on backup we plan two. More in the battery backup guide.
The Visayas grid logged 93 yellow and 30 red alerts from 1 January to 3 September 2026 (NGCP, via Daily Tribune).
For a ₱8,000 monthly bill at VECO’s Sep 2026 rate (₱14.89/kWh), our calculator suggests 6 panels (3.72 kWp) for about ₱145,000–₱170,000 battery-ready, or 7 panels with 1 battery for about ₱210,000–₱246,000. The itemised list prices are ₱157,200 and ₱227,900 before any promotion; the band allows for what the site visit confirms. VAT treatment is confirmed in your proposal.

EQUIPMENT AND WORKMANSHIP
One inverter family, one panel and one battery, plus the protection around them. Here is each piece and where it comes from, so nothing is implied that isn’t fitted.
| Component | What it does | In your estimate |
|---|---|---|
| 620 W N-type TOPCon panels | Make the DC power. The count comes from your kWh and roof space. | IncludedPriced per panel. Ask for the panel datasheet with your proposal. |
| Deye hybrid inverter (SUN-5K/6K-SG04LP1 or SUN-8K/10K-SG05LP1) | Converts solar to household AC, charges the battery and runs the backup circuits. Deye lists anti-islanding protection (IEC 62116). | IncludedSingle-phase 48 V, normally chosen with room for at least 20% more panels. |
| 5.12 kWh LiFePO4 battery | Stores daytime solar for the evening and brownouts. About 3.69 kWh delivered per battery on our cautious planning basis. | With backupPriced per battery when your goal includes backup. More may be added later; we confirm compatibility with your battery model and your utility. |
| DC isolation and surge protection | Isolates the array for service and limits lightning and switching surges. The PEC, as transcribed (Sec. 6.90.4), calls for accessible, labelled DC and AC disconnects. | IncludedDeye’s 8/10 kW SG05LP1 datasheet lists a built-in DC switch and Type II surge protection on DC and AC; for 5/6 kW models the protection fitted is listed in your proposal. The mounting, cabling and protection line adds breakers and an SPD. |
| Breakers | Protect each cable run, on the DC side and in the house wiring. | IncludedIn the mounting, cabling and protection line. |
| Backup sub-panel | Separates the circuits that stay on in a brownout from the rest of the house. | Only if listedWhen your goal includes backup. Not a separate line in the online estimate; your proposal lists it. |
| Earthing and bonding | Ties panel frames, rails and equipment to earth so a fault trips a breaker instead of energising metal. The PEC, as transcribed (Art. 2.50), requires metal parts and PV supports to be grounded. | IncludedPart of the installation. The existing earth electrode is checked at the site visit. |
| Arc-fault detection (AFCI) | Detects DC arcing. Listed as optional on Deye’s SG05LP1 datasheet. | Only if listedOnly if your proposal lists the AFCI-enabled variant. Ask; we don’t claim it otherwise. |
| Module-level rapid shutdown | Lowers rooftop DC conductors to 30–80 V within 30 seconds. PEC 2017 Sec. 6.90.2.6, as transcribed, requires it for PV circuits on buildings; to be confirmed against the official IIEE text. | Not standardNot in the standard online estimate. Your Professional Electrical Engineer confirms how Sec. 6.90.2.6 applies to your roof; any devices it requires should be a priced line in your proposal before you sign. |
Ask for the datasheet of every model you are quoted. Warranty terms for each component are confirmed in writing in your proposal.
The details that decide how a system rides out a typhoon season. Your proposal states them for your roof; the typhoon-ready installation guide explains why each matters.
Rails go through the roof sheet into purlins or rafters with sealed fasteners, never into the sheet alone.
Panel clamps sit only where the panel’s installation manual allows; elsewhere its load rating no longer applies.
Clamp and rail bolts are tightened to the specified torque. In storms, loosened clamps fail before panels do.
About a metre back from roof edges and corners unless the engineer’s calculation allows otherwise.
Near the sea, stainless fasteners and protected connectors. Jinko’s manual, for example, sets 50 m as a minimum distance from the shore.
Shaded, ventilated and above flood level, with the battery beside it and every cable labelled.
PERMITS AND APPROVALS
Permit and net-metering paperwork is part of the itemised estimate. The times below are legal maximums for government offices and utilities, not promises of a date.
A single-line diagram and electrical plans, signed and sealed by a Professional Electrical Engineer (RA 7920, Sec. 31(a) and 34).
Filed with your city or municipality before installation. Fees are set by each LGU.
Built to the Philippine Electrical Code and the approved plan. No grid-connected operation before the utility approves.
The Certificate of Final Electrical Inspection, issued after installation.
The ERC limits what the utility may require to four items: application form, CFEI, amended net-metering agreement and the certificate fee. Its impact study and testing are free.
The utility fits a bidirectional meter (homes pay at most ₱3,000 difference) and sends your papers to the ERC within 5 days of signing. Credits start from testing and commissioning.

Whether rooftop solar also needs a building permit or a structural engineer’s sign-off is set by each city’s Office of the Building Official, so it is confirmed for your address. Net-metering steps differ slightly by utility: see the net metering guide or your utility’s guide for VECO, MECO or CEBECO.
HANDOVER AND AFTER-SALES
The full list is confirmed in your proposal.
Solar runs quietly for years, but questions come up: a monitoring alert, a breaker that tripped, a plan to add a battery or an aircon. After handover you deal with us directly.
Response times, coverage and every warranty term are confirmed in your proposal, in writing.
Stay off the roof. Panels stay live whenever there is daylight, even with the grid down. Contact us through the form on this page so a check can be arranged before the system restarts, on the terms in your proposal. A yearly check of clamp torque is good practice.

STRAIGHT ANSWERS
Straight answers on cost, timing, permits, brownouts and support.
See real work first
The house on this page is an illustration, not a customer’s home, and we don’t show testimonials we can’t verify. If you’d like to see an installation before deciding, ask to see a recent one near you.
Ask to see a recent installation near youIt depends on your bill, your roof and whether you want a battery, so the final price follows a site assessment of your roof and wiring. As a guide, a battery-ready system for a ₱8,000 monthly bill at VECO’s Sep 2026 rate is about ₱157,200 on our itemised estimate (list price before any promotion).
The calculator on this page gives your own itemised figure in about 30 seconds, and our solar installation cost guide breaks the price down by system size.
We don’t promise an installation time before seeing your roof; the schedule is confirmed in your proposal. The paperwork has legal limits: 3 working days for the LGU electrical permit once documents are complete and fees paid, 7 for the CFEI (3 while the EO 110 energy emergency is in force), and 20 working days for the utility’s net-metering processing (10 under EO 110).
Real timing depends on complete documents and the utility’s impact study, so treat these as maximums, not a promised date.
Yes. Under RA 7920, electrical plans must be signed and sealed by a Professional Electrical Engineer and a permit secured before installation. You need an LGU electrical permit before work starts and a Certificate of Final Electrical Inspection (CFEI) after it; the CFEI is also one of the documents for net metering.
Some cities may also ask for a building permit for rooftop solar. That is confirmed with your Office of the Building Official. Permit paperwork is part of our itemised estimate.
Only with a battery, and only on the backup circuits. When VECO, MECO or CEBECO power drops, a grid-connected inverter must stop feeding the grid so line crews stay safe. A hybrid inverter with a battery disconnects from the grid and keeps a separate backup sub-panel running.
One 5.12 kWh battery gives about 7 hours of essentials such as a fridge, lights, fans and Wi-Fi (an estimate with no solar recharge). With an aircon on backup we plan two batteries.
Usually, yes. On GI or long-span metal, rails are fixed through the sheet into the purlins or rafters, never to the sheet alone. On a concrete deck, frames are mechanically anchored to the slab and the penetrations waterproofed. Tile roofs need hooks fixed to the rafters or battens per the racking maker’s manual; we confirm at the visit whether your tile roof is suitable.
The site visit checks the structure, the roof’s age and condition, and any repairs worth doing before panels cover them.
Homes across Cebu, including Cebu City, Mandaue, Talisay, Consolacion, Liloan and Minglanilla (VECO), Lapu-Lapu and Cordova (MECO), and towns served by CEBECO I, II and III. Share your barangay when you request a quote and we’ll confirm your utility and availability for a site visit.
It helps. Every system we quote uses a Deye hybrid inverter, so it is battery-ready, and choosing your backup circuits at the site visit lets the backup sub-panel be planned from the start.
Utilities are likely to treat adding a battery as a modification: under ERC Res. 15 §12 a modification follows the same process as a new application, so the utility is told first. Our battery upgrade guide covers the steps.
You can come back to us for system questions, monitoring alerts and faults. The monitoring app shows what the system is doing, and your handover pack lists equipment serial numbers and warranty documents.
After-sales and warranty terms are confirmed in writing in your proposal. After a storm, stay off the roof and contact us through the form on this page: panels stay live whenever there is daylight.
