Solar Power Calculation Formula:
| From: | To: |
The solar power kWh calculation estimates the amount of electricity a solar panel system can produce based on system size, hours of sunlight, and system efficiency. This helps determine the potential energy generation and return on investment for solar installations in the Philippines.
The calculator uses the solar power formula:
Where:
Explanation: The equation calculates the daily energy production by multiplying the system capacity by the available sunlight hours and adjusting for system efficiency losses.
Details: Accurate solar energy calculation is crucial for sizing solar systems appropriately, estimating energy savings, determining payback period, and making informed decisions about solar investments in the Philippine climate.
Tips: Enter system size in kW, average daily sunlight hours for your location in the Philippines, and system efficiency as a decimal (e.g., 0.85 for 85% efficiency). All values must be positive numbers.
Q1: What is the average sunlight hours in the Philippines?
A: The Philippines typically receives 4-6 hours of peak sunlight per day, varying by region and season.
Q2: What is a typical efficiency factor for solar systems?
A: Most grid-tied solar systems have an efficiency of 75-85% due to factors like inverter losses, temperature, and dirt on panels.
Q3: How does this help in calculating ROI?
A: By estimating daily kWh production, you can calculate monthly energy generation and compare it with your electricity bills to determine savings and payback period.
Q4: Should I consider seasonal variations?
A: Yes, sunlight hours vary throughout the year. It's best to use average values or calculate for different seasons separately.
Q5: Are there government incentives for solar in the Philippines?
A: Yes, the Philippines offers various incentives including net metering programs and tax incentives for solar installations.
