How much will your solar installation produce?

In the Northern Hemisphere, solar panels should ideally face True South (Azimuth 180°) to capture the most sunlight throughout the day. However, East-West facing panels are increasingly popular for maximizing morning and evening production, which often aligns better with household energy consumption.

The optimal tilt angle generally matches your geographical latitude (e.g., 43° for the South of France). A slightly steeper angle (50°+) performs better in winter when the sun is low, while a shallower angle (20°-30°) captures more energy during the long days of summer.

kWp stands for Kilowatt Peak. It represents the absolute maximum power a solar panel system can produce under ideal laboratory conditions (Standard Test Conditions). For example, a 3 kWp system has the theoretical capacity to output 3,000 watts during peak midday sun.
