If you’re wondering whether solar panels work on cloudy days, the answer is yes. Solar panels can continue generating electricity when the sky is overcast, although their output is generally lower than it would be under clear, sunny conditions.
This means cloudy weather does not prevent a solar system from producing energy. Even when direct sunlight is reduced, solar panels can still capture available daylight and convert it into electricity.
The simple answer is that solar panels do work on cloudy days – they just do not perform as well as they would on a bright sunny day.
The amount of electricity generated depends on factors such as cloud cover, panel efficiency, system size, the position of the panels and the amount of available daylight. Some estimates suggest solar panels may generate around 10–25% of their normal output under heavy cloud cover, although actual performance can vary significantly depending on conditions.
Modern solar systems are designed to generate electricity across changing weather conditions, making solar panels for cloudy days a practical option for properties that experience periods of overcast weather.
Cloud cover affects the amount of sunlight reaching solar panels, which can reduce daily energy generation. However, panels can still capture available daylight and convert solar energy into electricity.
Other factors that can affect solar output include:
The thickness and extent of cloud cover
The time of day
Panel orientation and tilt
Shading from buildings, trees or other structures
Panel efficiency and system size
Seasonal changes in available sunlight
The condition and maintenance of the solar system
A properly designed system takes these factors into consideration to help maximise energy generation throughout the year.
Geraldton’s generally sunny climate makes solar an attractive option for local homes and businesses. While cloudy days can temporarily reduce solar generation, a properly designed system can continue producing electricity whenever sufficient daylight is available.
If you’re considering solar for your property, explore Electric Cool Geraldton’s solar solutions to learn more about your options.
For properties that want to remain connected to the electricity grid, explore our grid-tied solar systems and learn how solar generation can work alongside your existing grid connection.
If you’re looking for greater energy independence, explore our off-grid solar solutions, which can combine solar generation with battery storage.
Solar batteries can help manage periods when solar generation is lower. Electricity generated when solar production is high can be stored for later use, depending on the capacity of the battery and the property’s energy consumption.
This can be particularly useful during evenings or periods of reduced solar generation, including cloudy weather.
The right battery and solar system combination depends on your property’s energy requirements, so a professional assessment can help determine what system may be suitable.

Yes, solar panels continue generating electricity on cloudy days in Geraldton, although reduced daylight can lower their energy output compared with clear, sunny conditions. The amount of electricity generated will depend on factors such as cloud cover, system size, panel efficiency and available daylight.
Solar output on a cloudy day varies depending on cloud cover, panel efficiency, system size and other conditions. Production can be considerably lower than on a sunny day, but panels can still generate electricity from available daylight.
Yes, Geraldton is well suited to solar power because its generally sunny climate provides strong solar generation potential throughout much of the year. Occasional cloudy weather does not prevent solar panels from generating electricity.
Yes, a solar battery can store surplus electricity generated during periods of higher solar production and provide stored energy when solar output is lower. Battery suitability depends on your property’s energy consumption, solar system and storage requirements.
