When it comes to solar energy, misinformation is everywhere. At SolarTherm UK, we believe in empowering homeowners and businesses with the facts—cutting through the noise to help you make informed decisions about going solar. From concerns about cloudy weather to outdated ideas about cost and efficiency, we’re here to bust the most common myths and set the record straight with real, evidence-based facts.
Myth 1: Solar energy is too costly
Fact: Solar energy is now one of the most cost-effective ways of powering your home. With clever design work and the right system, you can save up to 70% off your electricity bills. Return on Investment is also a lot quicker now, with simpler installations being paid back in full within just 5 years – with a solar panel’s lifespan exceeding 30 years, that’s over 25 years of free electricity!
Myth 2: Installing solar panels is complicated and requires high maintenance
Fact: Solar panel installation is relatively quick and straightforward when using an experienced approved installer like SolarTherm UK, most domestic installations take less than 1 day to install. Maintenance is minimal, with your solar panels requiring a clean every couple of years to remove stubborn dust or debris that isn’t removed with the rain.
Myth 3: Solar panels do not work in cold, snowy or cloudy conditions
Fact: It is understanding to believe this, but solar panels only require daylight to work effectively. Your solar panels will generate electricity in every weather condition – pretty lucky as we live in the UK with unpredictable weather at times!
Myth 4: Solar power can still power my home when there’s a power cut
Fact: This is partly true, but your solar PV system will not power your home in the event of a power cut straight out of the box. If you are connected to the grid your inverter will shut off generation of electricity during a power cut to protect the safety of engineers working to repair the grid fault. You can have an Emergency Power Supply installed alongside your solar PV system allowing you to have some power in the event of a grid failure.
Myth 5: Solar panels will cause damage to your roof
Fact: If your roof is in optimal condition before installation, solar panels can protect and preserve your roof. Part of the design process is assessing your roof for existing damage. If you roof does require maintenance, your solar panels are easily removed for easy maintenance.
Myth 6: Selling your home will be harder with solar panels
Fact: Many studies have shown that the value of your home can increase with a solar panel installation. Having a solar PV system installed can actually be a desired factor for those looking to purchase a house and save money on their future energy bills.
Myth 7: Solar panels are bad for the environment after 25 years
Fact: Modern solar panels are built to last in excess of 30 years. After this they can be recycled – which some manufacturers do free of charge.
Myth 8: The more panels you install, the faster your payback
Fact: It’s a common assumption that installing more panels means saving more money, but at SolarTherm UK, we believe the most efficient system is one designed to support your property and usage. Installing more than necessary drives up installations costs and results in a higher amount of energy being sold back to the grid at a lower rate than what you can purchase it at during off-peak tariffs.
Myth 9: You always need planning permission to install solar
Fact: Most UK homes can install solar PV panels under permitted development rights, meaning no planning permission is required. The only exceptions to this are listed buildings and properties located in a conservation area – but this can easily be resolved with an application to your local planning authority, which SolarTherm UK can guide you through.
