Standard Residential Panels Optimize Space and Handling: The industry-standard 60-cell panel dimensions (65″ × 39″ × 1. 5″) aren't arbitrary – they represent the optimal balance between power output, installation ease, and roof space utilization.
Adding panels of varying wattages can allow you to work within space or budget constraints when expanding your solar array. For example, you may find a good deal on 260W panels when your original system uses 250W panels.
