Solar panel capacity refers to the amount of power a solar panel can generate under standard test conditions. It is measured in watts (W) and directly affects how much electricity your solar power system can produce. The higher the capacity, the more power you get.
Size of a Single Panel Approx: 28 sq.ft Installable Panel Quantity: 10 Panels Required Roof Space: 28 * 10 = 280 sq.ft —————————————- Selecting the right installation capacity for your home PV system is a crucial step toward maximising your solar energy benefits.
A typical 20-panel system needs 340-400 square feet of unshaded roof area. Orientation: South-facing roofs provide maximum energy production Tilt: 30-45 degree angles optimize solar collection Shading: Minimal obstruction from trees, chimneys, or neighboring buildings Age: Roofs should have 10+ years of remaining life before panel installation
Measuring the available roof space is a crucial step in determining the potential capacity of your PV system. Begin by measuring the unshaded area on your roof where solar panels can be installed effectively. Unlike other regions, Sri Lanka, located close to the equator, enjoys efficient solar energy generation regardless of the panel direction.
