The Solar Photovoltaic Sizing Calculator is a valuable resource that assists in determining the required PV system capacity based on specific inputs.
The Formula of Solar Photovoltaic Sizing Calculator
The formula for calculating the PV System Capacity (kW) is:
PV System Capacity (kW) = (Total Annual Electricity Consumption) / (Solar Panel Efficiency × Solar Hours per Day × 365 days)
Where:
- Total Annual Electricity Consumption: The expected annual electricity usage in kilowatt-hours (kWh).
- Solar Panel Efficiency: The efficiency rating of the PV panels.
- Solar Hours per Day: The average daily sunlight hours available for solar power generation.
General Terms People Search For
Below is a table providing commonly searched terms related to solar photovoltaic calculations:
| Term | Description |
