Determining the hour angle is an essential step in calculating the position of the sun in the sky for solar energy applications. The hour angle defines the time of day in angular units relative to the solar noon position overhead. Calculating the hour angle properly is key to determining the sun’s declination angle and plotting…
Solar watches have become very popular as people seek out renewable, eco-friendly products. These watches have mini solar panels in the dial that convert light to electricity, eliminating the need for batteries. This self-charging capability has wide appeal. Many first-time solar watch buyers assume the watches will run perpetually for decades without maintenance since they…
Dealing with pesky pigeons on solar panels can be a real nuisance. From obstructing sunlight to causing damage with their droppings, pigeons spell trouble for solar panel systems.
