If you’re considering solar panels for your home in Essex, Suffolk, Kent or across the wider South East, you’ve probably come across conflicting information.
At SolarTherm UK, we speak to homeowners every day who are unsure what to believe – especially when it comes to performance, cost and environmental impact.
With years of hands on installation experience across the region, we’re here to clarify the facts. Below, we break down four of the most common solar PV myths and explain what really matters when deciding whether solar is right for your home.
Do Solar Panels Work in the UK Climate?
A widespread belief is that solar panels only work in hot, sunny environments. In reality, this assumption doesn’t hold up – especially in the South East and East Anglia.
Solar panels generate electricity from daylight, not heat. This means they continue to produce electricity even on cloudy or overcast days, common in UK weather patterns.
Excessively high temperatures can slightly reduce panel efficiency. Cooler climates like the UK can actually support consistent performance, making solar a viable solution year round. While on average 65%-75% of your annual total is generated from March-September, that doesn’t mean you can’t get meaningful generation throughout the winter months, especially on cool, crisp winter mornings.
Are Solar Panels Too Expensive for Homeowners?
Upfront cost is often the biggest concern for homeowners – and understandably so. However, the perception that solar will cost you upwards of twenty thousand pounds and is unaffordable is increasingly outdated.
Installation costs have reduced significantly in recent years, while energy prices have risen. This has shifted solar into a much more accessible and financially viable option for UK households. At SolarTherm UK, we have been operating since 2010, and in that time we have seen solar decrease in price by around 80%, improvements in large scale manufacturing of components, higher efficiency panels and high quality inverters have all contributed to the decrease in cost.
There are also funding schemes and incentives available in certain areas. For example, eligible homeowners may benefit from government backed programmes such as the Home Upgrade Grant, helping reduce or even cover installation costs in specific circumstances. Green Energy Loans are also making solar more affordable, offering low interest, long term loans that can be offset against monthly savings.
Over time, most households are seeing meaningful savings on their electricity bills, improving long term savings and rewards.
Can Solar Panels Power an Entire Home
Another common misconception is that solar panels can only provide partial energy for a home.
In practice, with smart design, a solar PV system can supply a substantial portion – and in some cases the majority – of a household’s daytime electricity needs. The exact output depends on factors such as roof size, orientation and energy usage.
Battery storage systems can further enhance this by storing surplus energy generated during the day for use in the evening or overnight. This significantly improves energy independence and reduces reliance on the grid.
At SolarTherm UK, we have customers who can support their complete daytime usage throughout the summer months and cover a meaningful proportion of their usage throughout winter by load shifting and prioritising high energy appliances during daylight hours.
Are Solar Panels Environmentally Harmful?
Manufacturing solar panels involves some carbon emissions, but this is minimal compared to the amount of carbon emissions they save. Once installed, solar panels produce clean, renewable electricity for decades. The carbon footprint is usually ‘paid back’ within three years of use.
For homeowners looking to reduce their environmental impact, solar remains one of the most effective long term solutions available.

Frequently Asked Questions
Do solar panels still work on cloudy days?
Yes. Solar panels generate electricity from daylight, so they continue working even when the sun isn’t directly visible.
How long does it take to see savings?
Most homeowners begin saving immediately on their energy bills, with long-term returns improving over time as energy costs rise.
Can I store unused solar energy?
Yes. Battery storage systems allow you to store excess electricity generated during the day for use later.
Are solar panels suitable for all homes?
Most properties are suitable, though factors like roof orientation, shading, and available space will influence system performance.
Are there grants available in my area?
Some homeowners may qualify for schemes like the Home Upgrade Grant, depending on location and eligibility criteria.
