Debunking Solar Myths and the Reality of Year-Round Solar Power

 Thursday, 31 August 2023

Over the last decade, solar technology has been revolutionised in its efficiency to harness the power of the sun. Misconceptions about solar lighting and power continue to circulate regarding their effectiveness during the colder months. In this article, we attempt to debunk these myths and highlight the truths relating to year-round solar lighting and power.

Myth 1: Solar Power fades in Winter

One of the most common myths surrounding solar power is that it becomes less efficient during winter. Contrary to this, solar panels are designed to work efficiently even in colder climates and are often more efficient at converting sunlight into electricity when operating at cooler temperatures. While shorter daylight hours might slightly affect the overall energy generation, advancements in solar technology, such as improved panel efficiency and energy storage systems, have minimised this impact. Solar power is a reliable energy source even in winter.

Myth 2: Cloudy days make solar panels useless

On a cloudy day you may think your solar panels are taking a break but fear not, solar panels can still generate electricity even on overcast days. While it's true that direct sunlight maximises energy production, solar panels still capture diffused sunlight and convert it into usable energy. Additionally, modern solar panels are designed to work efficiently in low-light conditions, allowing you to harness solar power even when the sky is overcast.

Myth 3: Solar lighting is dim and inconsistent

Solar lighting has come a long way and thanks to technological advancements, solar-powered lighting systems are now equipped with high-efficiency LED lights and sensors that provide bright and effective lighting. The energy generated from the sun during the day is stored in batteries, allowing them to shine throughout the night.

Prolectric’s specially developed smart light controller and Passive Infra-Red (PIR) sensor work to ensure the solar LED light lasts from dusk until dawn, even on the darkest days and are proven to operate throughout the UK winter.  Solar lights offer a reliable and eco-friendly solution without compromising on brightness, whether it's in car parks, pathways, or even work sites.

Myth 4: Solar Power is only viable in sunny climates

Solar panels can generate energy even in less sunny locations. While regions with more sunlight may generate more electricity, Prolectric’s solar technology has been engineered to work in the harshest of UK winters, where cloudy days make up 43% of the year.  Prolectric has provided over 8,000 solar lights across the UK brightening up car parks, walkways, and streets throughout the country.

Myth 5: Solar systems require a lot of maintenance

Solar systems are often perceived as high-maintenance due to concerns about cleaning panels and maintaining batteries. However, modern solar panels are designed with self-cleaning technology and many feature smart battery management systems that require little, to no manual intervention. Routine checks and occasional cleaning are usually sufficient to keep your solar system running effectively year-round.

At Prolectric, we offer access to our Lighting and Power Portal’s that provide remote monitoring, control and reporting to help you keep track of your solar equipment, ensuring it always runs efficiently, from anywhere.


Sustainable energy solutions are becoming increasingly vital in the fight against climate change and improving our environments. It’s important to separate fact from fiction and educate ourselves on the real capabilities of solar lighting and power. Solar technology advancements and real-world success stories debunk the myths that solar power is ineffective in winter, useless on cloudy days, and only suitable for sunny regions. Year-round solar lighting and power are feasible, practical and reliable options that contribute to a cleaner and more sustainable future.
