Solar energy is one of the leading contributors to renewable power generation in India. The rise of solar power energy in India has made solar photovoltaic (PV) panels a common choice for households and businesses seeking clean, sustainable energy solutions. But as solar panels become mainstream, one question still arises: do solar panels work in winter?

Initially, it may seem that solar energy is ideal for the summer. However, solar panels actually produce power throughout all four seasons. That’s because solar panels rely on sunlight, not heat, to generate electricity.

At Jindal India Renewable Energy, we are exploring the use of solar cells and photovoltaic (PV) modules to ensure access to clean, renewable energy for all. In this article, we will examine the ins and outs of solar panels and explain how weather affects their efficiency.

How do solar panels work?

Solar panels are made up of photovoltaic (PV) cells, which are composed mainly of semiconducting materials like silicon. When sunlight strikes the surface of the solar panel, these PV cells absorb energy. This ignites the movement of electrons inside the atoms, generating electric current. This current then powers our appliances, homes, and businesses. Alternatively, this current can be stored in a rechargeable storage battery for later use.

Do solar panels work in winter?

Yes, solar panels work in winter because they absorb energy from the sun’s light and not its heat. This means that solar energy is determined based on the amount of sunlight received and not necessarily the temperature. You may be surprised to know that solar panels work more efficiently during colder months. How? Well, that’s because electrons are at rest (low energy) during cooler temperatures, and upon being activated by sunlight (high energy), solar panels achieve a greater voltage difference and create more energy.

What about rain or snow?

Solar panel manufacturers design their products to endure different climates and weather elements, including rain and snow. The solar panels still receive the sun’s daylight through rain and snow and are able to generate electricity. In fact, rain can make solar panels even more effective at receiving sunlight by washing away dust from their surface. That being said, cloud cover or heavy snowfall can impact the amount of solar energy produced.

Factors affecting the efficiency of solar panels in winter

In a country like India that witnesses all four seasons–winter, summer, monsoon and autumn–solar power energy in India can be affected by the following factors:

1. Reduced sunlight hours

The days are shorter during winter, which means the solar panels receive fewer sunlight hours to generate electricity. The reduced exposure to sunlight directly affects the total energy output

2. Temperature

Solar panels are more efficient at converting sunlight into electricity in cooler temperatures. On very hot days, even with intense sunlight, solar panel performance can decline due to overheating.

3. Wind

Strong winds, which are common during winter, help cool the solar panels. This directly enhances their performance, as we know solar panels are more efficient in cooler temperatures.

4. Snow coverage

In regions with heavy snowfall, accumulated snow or ice on solar panels can block sunlight, preventing it from reaching the PV cells. However, solar panels often generate some heat, which can help melt light snow.

5. Cloud cover

Winter often brings more overcast days, which reduces the amount of direct sunlight reaching the panels. Although solar panels can still generate electricity from diffused light, the efficiency is lower.

The Bottom Line

Winter may bring shorter days and snowy conditions, but it doesn’t render solar panels ineffective. Solar panels rely on sunlight instead of heat and perform better in cooler temperatures, which ensures renewable power generation throughout the year. So, it’s safe to say that investing in solar energy is a wise choice no matter the season. As companies like Jindal India Renewable Energy foray into this sector, users can rest assured that solar panels will be effective year-round.
