During the peak hours of solar energy production, energy production is at its highest. This typically occurs when sunlight is most intense, usually between late morning and early afternoon. During this time, solar photovoltaic (PV) systems generate maximum electricity because their output directly correlates with sunlight availability.

The increased energy production during these peak hours is beneficial not only for solar system owners, who can generate and potentially sell excess energy back to the grid, but also for the overall energy supply. Utilities often rely on this additional solar power to help meet the higher demand for electricity during daylight hours.

While it is true that during peak production, energy costs might fluctuate and, at certain times, drop due to increased supply, the most notable aspect is that the production level of solar energy itself is maximized. This characteristic makes peak hours critical for optimizing solar energy usage and planning for energy needs.
