Here’s a deep dive into the sunny world of solar panels

Introduction

As solar panels gain popularity worldwide for being a clean and reliable source of renewable energy, one question still arises. Do solar panels work during winters? While the common belief is that since solar panels run on solar energy (and thereby heat), cold and cloudy months are bound to reduce their efficiency, the reality is a lot more promising.  

Solar panels rely on sunlight, not heat, to generate electricity. In fact, cooler temperatures can sometimes enhance their performance.  

If you’re looking for a comprehensive and fun understanding on the functioning of solar panels, here’s everything you need to know under 5 minutes: 

 

What impacts the working of a solar panel
 

What’s the science behind solar panels and temperature?

When sunlight hits the surface of a solar panel, the photovoltaic cells (PV cells) absorb energy. This triggers the movement of the electrons inside the atoms, thus current is generated. This current is then sent to our homes for use, or stored in a rechargeable storage battery for later. 

Solar panels work on sunlight, instead of heat. If anything, lower temperature in cold climate is optimal for the working of a solar setup. This is because the lower ambient temperature creates a higher voltage difference, ensuring that more energy is produced. 

But, do solar panels work when it rains?

In India, Karnataka and Tamil Nadu are among the states that receive maximum rainfall. Yet, they sit among the top 5 Indian states when it comes to solar power generation. This is because solar energy production is not impacted by rain, as much as it is impacted by the cloud cover. In fact, rain washes away the dust off solar panels, making them more effective at receiving sunlight.  

Let’s travel a little to the west. Take Florida for example— one of the wettest states in the USA, it ranks third in the country in terms of solar power generation.  
 

Do solar panels work in winter?

As long as there is light for the solar panels to capture, they will work. In winters, the days are shorter, and the sunlight can be affected by the cloud cover; these can reduce the output.  

Similarly, solar panels work in the snow. Even when the panel is covered with snow, sunlight reaches the surface to produce electricity, although at a lower rate. The construction of the panels—a dark reflective glass installed at a slanting angle—allows the snow to melt or slide off quickly. In case of heavy snowfall, manual removal of snow can also help maintain the process. The reflection of sunlight off the surface of snow is a classic example of the Albedo Effect at play—more sunlight hits the silicone panels than normal, leading to greater efficiency. 
 

Why should I get a solar panel?

Solar energy as one of the most reliable sources of clean energy is taking over the globe. If you’re still looking for a reason to switch, here’s a few: 

1. Solar panels not only take your dependency off the grid, they also help you save money. With a payback of 4-5 years on a solar setup, you’re as good as getting free electricity for the rest of your days. 

2. Trusted solar experts can help create setups that last years. Tata Power’s solar solutions keep you hassle-free for 25 years. Your electricity is on autopilot, and your life is simpler
