Solar production is usually strongest from late morning to early afternoon. Businesses that operate during daytime hours often benefit strongly from commercial solar.
10kW Grid-Tied Solar: Best for Bill Savings
A 10kW grid-tied solar system is usually the best setup for large homes and businesses that want lower monthly electricity bills without batteries.
How it works:
Your solar panels generate electricity during the day
Your property uses solar power first
If solar is not enough, power comes from the grid
If there is excess solar power and net metering is approved, it may go to the grid as bill credits
Meralco states that net metering allows qualified renewable energy facilities up to 100 kW to export excess renewable electricity, with the corresponding value credited to the customer’s next bill. Meralco also explains that a bi-directional meter measures import and export energy.
10kW Hybrid Solar: Best for Backup Power
A 10kW hybrid solar system includes batteries. It costs more than grid-tied solar, but it can provide backup power during outages.
Hybrid solar may be worth it if you need backup for:
Lights
Wi-Fi
CCTV
Refrigerators
Freezers
POS systems
Office computers
Selected outlets
Important business equipment
Essential home or commercial loads
Battery backup does not automatically mean your whole property can run normally during a brownout. High-load equipment such as aircon, electric ovens, large pumps, compressors, heaters, and heavy machines may require a larger inverter and bigger battery capacity.
Choose hybrid solar if backup power is important. Choose grid-tied solar if your main goal is lower monthly electricity bills.
5kW vs 8kW vs 10kW Solar System
