FAQs

A grid-tied system is connected to the local utility and reduces electricity bills through net metering.
A hybrid system combines solar panels with battery storage for backup power.
An off-grid system operates independently from the utility and is ideal for remote areas without stable electricity access.

Choosing the right system depends on your location, power reliability, and energy goals.

Net metering allows solar system owners to export excess electricity to their local distribution utility. The exported power is credited to your monthly bill based on ERC and utility guidelines.

System approval requires compliance with local utility standards and documentation.

Yes. Solar panels generate electricity even under cloudy conditions, though output may be reduced. The Philippines still receives sufficient annual solar irradiance to make solar systems financially viable year-round.

Proper system sizing accounts for seasonal fluctuations.

Most Tier-1 solar panels have a performance lifespan of 25 years or more. They gradually degrade at a low annual rate but continue producing electricity beyond the warranty period.

Inverters typically last 8–15 years depending on usage and environmental conditions.

A professional solar company should comply with:

• Philippine electrical standards

• Local building permits

• Utility interconnection requirements

• ISO-certified operational systems where applicable

NuPon Technology Phils. Corp. maintains structured quality systems as reflected in its corporate profile.

Solar suitability depends on:

• Structural integrity

• Roof orientation

• Shading conditions

• Available mounting area

• Electrical panel capacity

A professional site assessment determines feasibility before installation.

Yes. Studies globally show that energy-efficient homes and buildings with solar installations are more attractive to buyers and tenants due to lower operating costs and improved sustainability credentials.

When properly engineered and installed using certified mounting structures, solar systems are designed to withstand high wind loads common in the Philippines.

Installation quality is critical for structural safety.

Maintenance typically includes:

• Periodic panel cleaning

• Electrical inspection

• Inverter performance monitoring

• Mounting structure checks

Professional preventive maintenance ensures long-term efficiency.

Savings begin immediately after system activation. However, full financial return depends on:

• System size

• Electricity rates

• Energy consumption patterns

• Financing structure

Most Philippine installations achieve strong long-term ROI due to rising utility costs.
