Is DIY Solar Legal in the Philippines? Permits, Licences and What You Can Do Yourself

Buying and using solar equipment is legal in the Philippines, and you can set up plug-and-play solar yourself: a portable power station, charged from the wall or from portable panels plugged into its own solar input, following the manual. Wiring solar into your home is a different matter. Under RA 7920 Section 34, an electrical installation needs plans signed and sealed by a Professional Electrical Engineer (PEE), a construction permit secured first, and work done to the Philippine Electrical Code under a PEE, Registered Electrical Engineer (REE) or Registered Master Electrician (RME).

This guide quotes the law and the electric company rules directly, explains what they mean for a homeowner, and draws a clear line between what you can do yourself and what needs a licensed professional. It’s general information, not legal advice; for your specific property, ask your LGU’s building official or a licensed PEE.

What the law says about electrical work

The main law is Republic Act No. 7920, the New Electrical Engineering Law. Four sections matter for solar.

Section 34: plans, permit, code and supervision

Section 34 is the core rule. It says:

“It shall be unlawful for any person not authorized under this Act to prepare plans, designs, valuations or specifications for any electrical wiring, equipment or system; and no installation thereof shall be undertaken unless the plans, designs, valuations and specifications have been prepared by or under the responsible charge of, and signed and sealed by a professional electrical engineer; and a construction permit for the execution thereof is first secured; and unless the work is done in accordance with the Philippine Electrical Code and is executed under the responsible charge or supervision of a professional electrical engineer, a registered electrical engineer, or a registered master electrician, as the case may be…”

Read it as a checklist. For an installation of “any electrical wiring, equipment or system”:

1. Plans prepared by or under, and signed and sealed by, a PEE.
2. A construction permit secured before work starts.
3. Work done to the Philippine Electrical Code (PEC).
4. Supervision by a PEE, REE or RME, as the case may be.

The quoted text doesn’t make an exception for small or solar systems. A solar setup wired into your home is electrical wiring, equipment and a system.

Section 31(a): who seals plans

“A professional electrical engineer’s field of practice includes the sole authority to seal electrical plans, etc., and to practice electrical engineering in its full scope as defined in this Act”.

Only a PEE can seal the plans. An installer who says “no need for plans” for a wired-in system is skipping a legal step.

Section 31(c): what a master electrician may do

“A registered master electrician’s field of practice includes the installation, wiring, operation, maintenance and repair of electrical machinery, equipment and devices, in residential, commercial, institutional, commercial and industrial buildings … Provided, That if the installation or the machinery is rated in excess of five hundred-kilovolt-amperes (500 Kva), or in excess of six hundred volts (600 V) the work shall be under the supervision of a professional electrical engineer or a registered electrical engineer.”

So a Registered Master Electrician can do residential installation and wiring work, with PEE or REE supervision required above 500 kVA or 600 V. The plans still need a PEE’s seal under Section 31(a) and Section 34.

Section 32(a): practising without a licence

Section 32(a) says no person shall:

“Practice or offer to practice electrical engineering in the Philippines without having previously obtained a certificate of registration and a professional license from the Board of Electrical Engineering except as provided for in Section 14 hereof”.

The Philippine Electrical Code

Section 34 requires work to be “done in accordance with the Philippine Electrical Code”. The PEC text isn’t freely published online, so we don’t quote any clause from it. Your PEE and electrician work to it; you don’t need to read it yourself, but you should expect them to follow it.

Permits and the CFEI

For a solar system wired into your home, the paperwork usually runs:

• Construction (electrical) permit from your LGU, before work starts, based on PEE-sealed plans. Section 34 requires this permit “first”.
• Certificate of Final Electrical Inspection (CFEI) from your LGU after the work. Meralco lists a “Certificate of Final Electrical Inspection (CFEI) from your LGU” among its net-metering application requirements.

Requirements and fees vary by LGU. Our solar installation guide walks through the order of permits, inspections and utility steps for a full rooftop system.

The electric company side: net metering and Zero Export

Even if you only want to use your own solar power, a system connected to your home’s wiring involves your electric company. Meralco’s net-metering FAQ says three important things:

• Without net metering, “the excess electricity your solar PV produces may be recorded as imported energy from Meralco”. You could end up billed for energy you produced.
• “Even for solar systems intended solely for own consumption, it is important to inform Meralco.”
• “If you do not intend to export excess electricity to the grid, you may signup for Zero Export (ZE) instead of Net-Metering.”

Meralco’s eligibility for net metering is an RE system with “a capacity of up to 100 kW (100 kWp for solar PV)”.

What net metering is

The Department of Energy’s primer describes it like this: net metering “allows customers of Distribution Utilities (DUs) to install on their premises … a Renewable Energy (RE) facility not exceeding 100 kilowatts (kW) in capacity so they can generate electricity for their own use. Any electricity generated that is not consumed by the customer is automatically exported to the DU’s distribution system.”

Exports earn “peso credits … equivalent to the DU’s blended generation cost, excluding other generation adjustments”. The rules come from ERC Resolution No. 09, Series of 2013, as amended by Resolution No. 06, Series of 2019.

Every electric company and electric cooperative runs its own application process. Find yours in our net metering guide by utility, and read the net metering explainer for how credits work.

What a homeowner can safely do yourself

Here’s the line we draw. Plug-and-play portable panels and power stations can be set up by the owner following the manual. Anything wired to the house, a breaker panel, the roof or the grid needs a licensed electrician or PEE and an LGU electrical permit, and grid connection needs the electric company’s process.

You can do yourself

• Use a portable power station. Charge it from a wall outlet, and plug your fan, router, lights or laptop into its outlets during a brownout. Nothing is installed.
• Charge it with portable panels plugged into the station’s own solar input, using a pairing the station’s maker supports. Our solar for power stations guides list verified pairings, model by model.
• Plan and size. Work out your loads in watt-hours, compare options and collect quotes. Our DIY solar backup sizing guide and the power station runtime calculator help.
• Learn the technical checks so you can ask installers better questions: MPPT vs PWM controllers, matching panels to a controller and hybrid inverters.
• Check credentials. Ask any installer who the PEE signing your plans is, and who will supervise the work.

Needs a licensed professional

• Fixing panels to your roof and running cables into the house.
• Connecting a charge controller, battery bank or inverter to your home’s circuits.
• Any change at your breaker panel, including a backup sub-panel or transfer switch.
• Hybrid or grid-tied inverters of any size.
• Anything that connects to, or could feed power into, the grid. That also needs your electric company’s process.

Grey areas homeowners ask about

Some setups sit between “plug-and-play” and “wired into the house”. The law’s wording is the safest guide: Section 34 covers the installation of “any electrical wiring, equipment or system”. When in doubt, treat it as an installation and ask your LGU’s building official or a PEE.

Portable panels left outside all the time. A portable panel set out on a balcony or in the yard and plugged into a power station’s solar input is still plug-and-play. Check the panel’s own rating first: BLUETTI, for example, says not to expose its PV200 folding panel to rain. Check your own panel’s manual before leaving it out through the rainy season.

Panels fixed to the roof, cabled to a power station indoors. Once you’re fixing panels to the roof and running permanent cable through walls or ceilings, you’re installing electrical wiring and equipment. That needs a licensed professional, and roof work during typhoon season is a safety risk in its own right.

A battery-and-controller system that never touches the house wiring. A stand-alone DC setup with its own panels, controller and battery is still “electrical wiring, equipment or system” in the plain words of Section 34, and the quoted text doesn’t exempt small or off-grid systems. Batteries and series panel strings also carry real fire and shock risks. Have it designed and installed by licensed people.

Self-contained solar gadgets. Products with a built-in or plug-in panel, such as solar floodlights or battery cameras with a small charging panel, don’t connect to your home’s circuits. You install them like any other gadget, following the manual.

A power station connected to a house circuit. This is not plug-and-play. Supplying any part of your home’s wiring from a power station needs proper switching equipment installed by a licensed electrician.

Plug-and-play options from our product list

These need no wiring. Follow each manual for setup and charging.

• EcoFlow RIVER 3 Plus: 286 Wh LFP battery, 600 W AC output, up to 220 W solar input, and a 10 ms UPS switchover listed on EcoFlow’s PH store. Expandable to 858 Wh with an extra battery. A good fit for Wi-Fi, a fan and lights. See our RIVER 3 Plus buyer guide.
• EcoFlow DELTA 3 1500: 1,536 Wh, 1,800 W AC output, up to 500 W solar input, 15 ms UPS switchover, expandable to 5.5 kWh with extra batteries. For longer brownouts and bigger loads. See our DELTA 3 1500 buyer guide.
• BLUETTI Elite 30 V2 with the BLUETTI 60W panel: BLUETTI sells this pair as an official kit with a DC5521-to-XT60 cable. The station is 288 Wh with 600 W AC output, and its manual says not to use panels with an open-circuit voltage above 28 V, so use one 60W panel (27.5 V) and no other panel from our list. The station doesn’t come with a solar cable, and the Lazada panel listing’s variant mentions a “5521 TO 7909” cable, which fits other BLUETTI models, so confirm you’re getting the XT60 cable.

To estimate how long any of these would run your appliances, use the power station runtime calculator or read how to calculate power station runtime. For a broader look at brownout options, see backup power for brownouts.

If you want a wired-in system

If plug-and-play isn’t enough and you want panels on the roof, a battery bank or a hybrid inverter feeding your house circuits, plan it properly:

1. Size it from your bills and brownout needs. The solar system size calculator gives a first estimate.
2. Choose the system type. Our comparison of on-grid, hybrid and off-grid solar explains the options.
3. Find a licensed installer. Start with our solar installers directory and get written quotes that name the PEE.
4. Permits: the installer secures the LGU electrical permit before work and the CFEI after.
5. Utility: inform your electric company, and apply for net metering or Zero Export as appropriate. See net metering.

Bottom line

DIY solar is legal when it stays plug-and-play: a power station charged from the wall or from portable panels plugged into its own solar input, set up per the manual. Once solar is wired into your home, RA 7920 Section 34 applies: PEE-sealed plans, a construction permit first, work to the Philippine Electrical Code under a PEE, REE or Registered Master Electrician, then a CFEI from your LGU. Tell your electric company about any wired-in system. Meralco warns unmetered exports may be recorded as imports, and offers Zero Export if you won’t export. If you want to sell power back, apply for net metering.
