What is the recommended orientation for PV panels to enhance energy efficiency?

The recommended orientation for photovoltaic (PV) panels to enhance energy efficiency is to align them to maximize sun exposure. This positioning is crucial because PV panels generate electricity when exposed to sunlight, and the more sunlight they receive throughout the day, the more energy they can produce.

Positioning panels to face the sun directly, typically oriented toward the equator (south in the Northern Hemisphere and north in the Southern Hemisphere), optimizes their performance. This alignment allows the panels to capture the most solar radiation, particularly during peak sunlight hours, improving overall energy output.

Other orientations, such as facing straight up towards the sky, would not be as effective because the angle of incidence of sunlight is not optimal for energy capture. Similarly, installing panels at random angles could lead to inefficient energy production as it does not consider the sun's path across the sky. Positioning the panels away from natural sunlight would drastically reduce their capability to generate electricity, making it a poor choice for maximizing energy efficiency. Thus, aligning to maximize sun exposure is the best practice for achieving high energy production from PV panels.
