For instance, states like California and Arizona generally experience robust solar energy generation, with clear skies and an abundance of sunshine. In contrast, regions with temperate or colder climates may experience reduced performance during certain seasons. Therefore, evaluating potential geographic and climatic limitations cannot be underestimated when estimating a solar panel system’s overall efficiency and wattage output.

3.2 SHADING EFFECTS

Another crucial factor that can inhibit solar panel performance is shading. When even a small portion of a solar panel is obstructed by trees, buildings, or other structures, it can result in significant energy losses. The phenomenon known as the “shading effect” can dramatically affect the panel’s output, limiting its wattage capacity.

In order to maximize energy capture, homeowners should assess the surroundings of their solar panel setup and consider trimming trees or relocating objects that may cast shadows on the panels. This proactive approach facilitates optimum energy generation by ensuring that the panels receive as much direct sunlight as possible throughout the day.

4. ROOFTOP SOLAR SYSTEM CONFIGURATIONS
