Solar panels can charge our power banks, lights, and portable power stations by converting sunlight into electrical energy. Light hits the panel and generates a current to harness energy and power our devices. Despite what you may think, light, not heat, cultivates the energy provided. So, even if it's a breezy, cool day, the light collected will create the energy needed. Even reflected light will be enough for the panel to create energy, though it won't be as quick as a direct ray.
Despite the changing of seasons, in the northern hemisphere, you should always face your solar panels south to enhance efficiency and harness the maximum amount of power. Facing panels south makes them more productive, especially when the weather features a bright, sunny day. However, if you're in the southern hemisphere, you should face your solar panels toward the north because the sun travels through the northern portion of the sky.
Clear, average temperature days offer the best conditions for charging. Solar panels reach maximum efficiency when the sun is at its highest point at midday. But, this doesn't mean that they won't be operational when the sun hides out behind the clouds.
If your solar panels come equipped with a kickstand, you can angle it to allow maximum sun exposure, speeding up the recharging process for your power banks and power stations.
