- Receive bill credits at the same rate you pay for electricity
- Roll over unused credits for up to 12 months
- Install systems up to 100 kWp without additional fees
Return on Investment (ROI)
With current electricity rates and solar costs, most Filipino homeowners achieve payback in 5-7 years. Over a 25-year system lifespan, total savings can reach ₱1-3 million depending on system size and electricity consumption.
💡 Pro Tip for Filipino Homeowners
Start with a system that covers 80-90% of your daytime consumption. This maximizes self-consumption and minimizes export to the grid, giving you the fastest payback period. You can always expand later!
Factors Affecting Solar Panel Prices
- Panel Quality: Tier-1 brands (Longi, JA Solar, Canadian Solar) cost more but offer better warranties and efficiency
- Inverter Type: String inverters (₱80k-150k for 5kW) vs Hybrid inverters (₱120k-180k for 5kW)
- Roof Type: Concrete roofs are easier and cheaper to install than metal or tile roofs
- Location: Installation costs vary by region due to labor rates and logistics
- System Size: Larger systems have lower per-watt costs due to economies of scale
Frequently Asked Questions
How long do solar panels last in the Philippines?
Quality solar panels last 25-30 years with minimal degradation (0.5% per year). Inverters typically last 10-15 years and may need replacement once during the system’s lifetime.
Do solar panels work during rainy season?
Yes! Solar panels generate electricity even on cloudy days, though at reduced capacity (10-25% of peak output). The Philippines’ year-round sunshine ensures consistent annual generation.
Is financing available for solar in the Philippines?
Yes, many banks offer green energy loans with competitive rates (6-12% p.a.) and terms up to 10 years. Some solar installers also offer in-house financing options.
How much roof space do I need?
Approximately 6-7 square meters per kW of solar capacity. A typical 5kW system requires 30-35 sq.m of unshaded roof space.
