How To Charge Solar Lights When It's Cloudy?

How to Charge Solar Lights on Cloudy Days

The intensity of the sun is scattered through clouds. However, overall daylight is still transmitted through solar radiation. Solar radiation is a measurement of the brightness of the entire sun, expressed as wavelengths of light. In short, this allows the system to charge even on cloudy days or days with little sunlight.

How does solar lighting work without sunlight?

All solar panels are made of solar cells, also known as photovoltaic cells, which are made of semiconductors. This converts sunlight into electrical energy. When sunlight directly contacts these cells, electrons break away from their atoms and flow through the cells. This energy creates electrical charges that move in response to the electric field inside the cell, causing an electric current to flow.

Determine Light Quality

When considering a solar light solution, you must define "light quality." Light quality refers to the uniformity of the light provided by a solar lighting system. For example, you'll notice the light quality on a street or parking lot, where there are both bright and dark spots on the ground. While the human eye is good at adjusting from day to night, it's not as good at processing both bright and dark areas at the same time. Traditional high-intensity lights are often so bright that it's difficult for the eye to make this adjustment. Thanks to advancing technology, LED lighting can provide lower, more uniform illumination and better light quality than high-intensity lamps, benefiting all users.

Light Level Guarantee

Thanks to the impact of LED improvements, solar LED lighting systems can provide light levels recommended by the Illuminating Engineering Society (IES), the recognized authority on lighting performance in North America. Solar LED lighting systems are able to meet recommended standards for street lighting, parking lots, roadways, and security applications.

Depending on your application, your lights may need to meet IES levels during specific hours. While some solar LED lighting systems appear to meet IES light levels, they may not be able to do so during inclement weather because the systems are not properly sized and rely on ineffective dimming.

At the same time, when dimming is used effectively, it can help ensure that your system will meet your desired light levels during the hours you need them each night. High-quality LEDs, efficient batteries, and durable solar panels ensure that the system you purchase today will perform exactly as planned throughout its life. If you need light, you can get it without compromising light levels.

Go Green with Solar!

Solar energy is undoubtedly one of the cleanest, most widely available, and most abundant renewable resources. In many parts of the world, there is no shortage of sunshine. Even in areas not typically known for their consistent sunshine, there is still enough sunshine to keep solar panels functioning properly.
