22nd Nov 2024

Winter in Kent often paints a grey, misty picture, leaving many homeowners and businesses wondering: Do solar panel installations work during the colder months? It’s a common misconception that solar panels rely on hot, sunny days to function.

Let’s explore how solar energy fits perfectly into Kent’s climate—even in the heart of winter.

How Solar Panels Work in Winter

First, let’s clear up a big misunderstanding: solar panels don’t need heat to generate electricity—they need daylight. Solar panels have photovoltaic (PV) cells that convert light into energy. When sunlight hits the cells, it creates an electric field, producing electricity.

Excessive heat reduces the efficiency of PV cells, but during cooler months, panels operate closer to their optimal temperature range, leading to consistent energy output. Many solar panel systems are tested to withstand temperatures as low as -25°C, making them suitable for even the most challenging UK weather conditions.

 

Solar Panels Kent: What to Expect in Winter Conditions

Kent’s winters are known for their cloudy skies, intermittent rain, and the occasional frosty morning. But how does this impact solar energy production?

The good news is that solar panel systems don’t need direct sunlight—they work with daylight, even when the sky is overcast. On a typical winter’s day, Kent still receives around 8-9 hours of daylight, which is more than enough to keep panels generating electricity.

However, the difference lies in quality. High-end panels excel in low light, while cheaper ones may falter. Our SunPower panels deliver 60% more energy over 25 years, backed by performance data from over 35 million solar panels installed worldwide.

 

Efficiency of Solar Panels in Cold Weather

Cold weather isn’t a foe—it’s a friend to your solar panels.

Solar panel systems operate more efficiently at cooler temperatures. Heat can reduce the performance of PV cells, but a brisk winter’s day ensures your panels work at their best. It’s why some of the world’s leading solar nations, like Germany and Sweden, boast successful solar installations despite their cold climates.

In fact, Germany—a country famous for its grey skies—generates enough solar power to meet 12% of its energy needs. If solar works in a place like that, Kent’s winters are no challenge at all.

 

Cloudy Days: Does the Sun Still Shine Through?

One of the most common concerns in a region like Kent is whether cloudy weather makes solar PV systems redundant.

While production might be lower than on a sunny day, a solar PV system can still capture and convert diffuse light. In fact, they often work at 10-25% of their maximum capacity under overcast skies. For context, that’s still enough to power key appliances in your home.

And let’s not forget: even on cloudy days, the sun is shining above the clouds. Rest assured, your panel installation in Kent will be busy soaking up the daylight.

 

What About Snow, Frost, and Rain?

When it comes to winter weather, these are the three big questions homeowners and business owners ask:

• Snow: While snow is rare in Kent, solar PV systems are installed at an angle, allowing snow to slide off. Even a light dusting won’t block sunlight for long.
• Frost: Panels are built from durable materials that resist freezing temperatures without affecting performance.
• Rain: Believe it or not, rain can be beneficial. It washes away dirt and debris, keeping your panels clean and efficient. So, every drizzle is a free rinse for your solar system!

 

Battery Storage: Making Winter Power Go Further

Shorter days mean less daylight, but that’s where battery storage comes in. The Tesla Powerwall battery stores excess energy generated during sunnier periods, allowing you to use it when production dips. Its 13.5 kWh storage capacity is typically sufficient to power a standard UK home during the evenings or low-sunlight hours.

This system allows solar panels to continue generating power during outages too—which standard setups without batteries cannot do. Moreover, its time-of-use grid purchasing capability means you can buy energy cheaply during off-peak hours, store it, and use it during high-cost periods.

 

The Longevity and Durability of Solar Panels in Winter

Our SunPower Solar PV Panels are backed by extensive third-party testing and comprehensive 40-year warranty coverage. They’re built to handle a range of conditions, from hailstorms to strong winds. In short, Kent’s mild winters are no match for a good quality solar system.

What about maintenance? Panels require minimal upkeep, even in winter. If snow or debris accumulates (which is rare in Kent), a quick brush-off is usually enough to restore full efficiency. The robust design ensures your investment continues to pay off year after year, regardless of the season.

Additionally, we can help keep your system running smoothly, whether we installed your solar panels or not. Our maintenance services cover the South East, including Kent, London, parts of Essex, Surrey, and East Sussex.
