"CRITICAL FACTORS EVERY PROPERTY OWNER MUST EVALUATE BEFORE COMMITTING TO A SOLAR INSTALLATION TO AVOID RISKS"
(Actual video at Cagayan de Oro: burnt solar photovoltaic system due to faulty installation; wasted investment)
In the Philippines, the installation of a solar photovoltaic (PV) system is a regulated practice of electrical engineering. Under Republic Act No. 7920 (New Electrical Engineering Law) and the Philippine Electrical Code (PEC), only licensed professionals are legally authorized to design, supervise, and execute these installations.
LEGAL & TECHNICAL FRAMEWORK
The following laws and codes dictate how solar services must be rendered:
*Republic Act No. 7920: Mandates that a valid certificate of registration and professional license from the Professional Regulation Commission (PRC) are required to practice electrical engineering.
*Republic Act No. 11711 (2022): Amends the Contractors’ License Law, imposing significantly harsher penalties for unlicensed contracting to ensure public safety.
*Philippine Electrical Code (PEC) 2017: The primary safety standard for all electrical installations in the country
AUTHORIZED VS. PROHIBITED INSTALLERS
Only the following licensed electrical practitioners are legally allowed to handle solar PV systems:
*Professional Electrical Engineer (P*E): Authorized to sign and seal electrical plans for any system size. Mandatory for systems above 4 kW or those requiring net metering.
*Registered Electrical Engineer (REE): Authorized to supervise the installation, operation, and maintenance of the system.
*Registered Master Electrician (RME): Allowed to install and supervise work for systems up to 500 kVA and 600 Volts.
WHO IS NOT ALLOWED:
*DIY Service Providers: Individuals without a PRC license cannot legally sign permits or certify that an installation is safe.
*Unlicensed Contractors: Any entity offering solar services for a fee without a Philippine Contractors Accreditation Board (PCAB) license is operating illegally.
*Independent Technicians: Even TESDA-certified installers (NC II) must work under the direct supervision of a licensed P*E, REE, or RME.
CRITICAL SAFETY & TECHNICAL PROTOCOLS
Licensed professionals must adhere to specific PEC 2017 requirements to prevent fire and electrocution.
RISKS AND LEGAL CONSEQUENCES FOR CLIENTS HIRING UNREGISTERED or "fly-by-night" installers exposes homeowners to severe risks:
*Criminal & Financial Liability: Under RA 11711, unlicensed contractors face fines between ₱100,000 and ₱500,000, plus a percentage of the project cost.
*Permit Denial: Local Government Units (LGUs) will not issue Building or Electrical Permits without a plan signed and sealed by a P*E.
*Net Metering Rejection: Utility providers require a Certificate of Final Electrical Inspection (CFEI) signed by a licensed professional to approve grid connection and credits.
*Safety Hazards: Improperly installed systems are the leading cause of electrical fires in rooftop solar. Unregistered installers often skip critical safety features.
CHOOSING A LEGITIMATE AND REGISTERED INSTALLER
To avoid "fly-by-night" operators and ensure your system is safe and eligible for government incentives, follow these verification steps:
*Check Official Registrations:
DOE Registry: Verify if the company is on the Official DOE Solar PV Installer Registry. Registration with the Department of Energy indicates compliance with national safety and quality standards.
PCAB License: A Philippine Contractors Accreditation Board (PCAB) license is a key indicator of legitimacy, ensuring the firm has certified engineers and electricians.
DTI/SEC & Business Permits: Confirm the company is legally registered with the DTI or SEC and possesses a current local business permit.
Verify Experience and Workforce: Look for installers with at least a decade of experience and a visible portfolio of completed projects. Prefer companies with in-house installation crews rather than those who outsource to third-party contractors to ensure better accountability and workmanship consistency.
Review Warranties and Support: Legitimate providers offer clear, written warranties—typically 25 total years for panel performance and 5 to 10 years for inverters and workmanship.
Demand a Professional Proposal: A reputable installer will always conduct a site survey and provide a detailed quote that includes equipment brands, estimated energy production, and assistance with Net Metering applications.
Prioritizing safety and rigorous professional standards ensures the long-term integrity of the property and the well-being of its occupants during solar installation.
Always verify an installer's credentials!👷
