Photovoltaics can work great even in the fall. Experts advise how to get the most out of it

Less sun, but still plenty of energy
In Slovak conditions, the intensity of solar radiation decreases during the winter, and thus the output of photovoltaic panels. However, this does not mean that the panels stop producing electricity. Even in the cold months, they can cover part of the household's consumption, usually around a fifth of the summer output.

Modern photovoltaic systems can also work effectively in diffused light - that is, when the sky is cloudy. Although production is not as high as in summer, it is still a significant contribution to reducing consumption from the grid.

Correct orientation and inclination of panels
The location of the panels has the greatest impact on the performance of the solar system. In Slovak conditions, it is recommended to orient them to the south, ideally with an inclination of approximately 30 degrees. This angle represents a reasonable compromise for year-round operation.

If the goal is to increase production in the winter months, a slightly larger inclination - around 50 to 60 degrees - can help better capture the low winter sun and at the same time facilitate snow sliding. In practice, however, most households leave their panels in the year-round setting, which is the most efficient on average throughout the year.

Maintenance is important
In order for photovoltaics to provide stable performance, they require basic care.

In autumn and winter, it is recommended to:

-Remove dirt and dust - even a thin layer can reduce performance by several percent.

-Remove snow from the panels if a thicker layer forms on them. A thin layer of snow usually does not interfere and, thanks to the reflection of light, can even help slightly.

-Check the shading of trees and branches that can cause shade during the low winter sun.

-Visually inspect the system from time to time - for loose connections, damaged brackets or cracked panels.

-Although it may seem like a small thing, regular maintenance can increase the total annual electricity production by tens of kilowatt hours in the long run.

Cold is good for panels
Interestingly, solar panels generally do well in lower temperatures. While extreme heat can slightly reduce efficiency in summer, the opposite effect is seen in winter – cold helps maintain better conductivity of materials, which has a positive effect on performance.

This means that even though there is less winter sun, each captured ray is converted into electricity slightly more efficiently than on hot summer days.

How to make the most of energy
Households that also use photovoltaics for heating can set their system to make the most of the energy produced during the day.

Reducing heating by 1–2 degrees in the evening can reduce grid consumption and make the most of daily production. Battery storage allows you to store energy produced during sunny hours and use it in the evening.

In winter, it is recommended to fully charge the battery at least once every three weeks to maintain its capacity. Such small adjustments can bring significant savings, especially in times when electricity is more expensive and household consumption is growing.

Photovoltaics make sense all year round
Although autumn and winter are not ideal for solar panels, photovoltaics make sense at any time of year. A properly set and maintained system can produce electricity even on cold and cloudy days.

Anyone who takes care of their power plant can be sure that it will bring them savings not only in summer but also in winter - and at the same time extend its lifespan by years.
