Do solar panels work on cloudy days?
Solar panels allow you to harness the sun's clean, renewable energy, reducing electricity bills and environmental pollution. But do solar panels work during cloudy and sunless seasons? This is a key question to consider before installing solar panels.
In this article, we'll discuss how solar panels work on cloudy days, whether solar panels work at night, and how to make sure you always have electricity available—even if your panels can't generate solar energy.
How solar panels work on cloudy days
Photovoltaic (PV) solar panels can use sunlight directly and indirectly to generate electricity. This means they can still work efficiently even with cloud coverage. Still, solar panels are most efficient and generate the most electricity when they absorb direct sunlight on a sunny day.
Although the light is reflected or partially blocked by clouds, the solar panels will still work, but their generating capacity will be diminished. On average, solar panels produce only 10 to 25 percent of their normal power output during periods of cloud cover.
Clouds are often accompanied by rain, and here's a fact that might surprise you: Rain actually helps solar panels work more efficiently. This is because rain washes away any dirt or dust that collects on the panels so that they can absorb sunlight more effectively.
Do solar panels work at night?
While solar panels can still work on cloudy days, they can't work at night. The reason is simple: solar panels work on a principle called the photovoltaic effect, in which solar cells are activated by sunlight, producing an electrical current. Without light, the photovoltaic effect cannot be triggered, and electricity cannot be produced.
Store solar energy for cloudy days and at night
During sunny hours, your solar panels may actually produce more power than you need. This excess power can be used to provide additional power on cloudy days or at night. But how do you store that energy for future use? There are several options to consider:
You can store excess energy in a battery.
When you add batteries to a solar installation, any excess power can be collected and used during periods of poor sunlight, including nights and particularly cloudy weather.
Batteries allow you to run your solar PV system throughout the day, but some disadvantages of battery storage need to be noted:
1. This is another thing you need to install.
2. It increases the total cost of your solar system.
3. Batteries take up some space.
4. If you need power for more than a few hours, you may need multiple batteries.
