In terms of renewable electricity sources in the UK, solar power continues to increase in popularity. However, solar has had many misconceptions about being a reliable source of electricity. 

Onboard Energy discovers the common myths about solar power and whether they’re true or false. 

False: Solar panels are too expensive 

A common myth associated with solar panels is the cost of buying them. However, the cost of solar continues to drop. This is due to the availability of solar panel kits, thus making the solar transition cheaper and easier. Installing solar panels is a long-term investment as it will save you money with your energy costs long-term. 

True: Installing solar panels is easy 

You may think that installing solar panels on your narrowboat or campervan is complicated. However, it is a job that can be done yourself. All you need is the following equipment: 

  • A charge controller  
  • Circuit breakers 
  • Combiner boxes 


False: Solar panels require regular maintenance 

Solar panels require no maintenance since they have no moving parts. We recommend cleaning your panels a few times a year. We also suggest removing any debris and identifying potential wear and tear on the wiring or panels. Checking your batteries is essential for ensuring your narrowboat or campervan generates electricity safely and effectively. 

True: You can recycle solar panels 

It is a myth that solar panels cannot be recycled since most panels are made from glass, metal and silicon. Previously, it would have been expensive to recycle panels as it would have been difficult to disassemble the parts. Due to increased demand for solar power, companies and councils across the UK have the infrastructure to recycle panels.  

False: Solar panels don’t last a long time 

Do solar panels last more than a few years? The panels can last a long time and it is common for manufacturers to offer a 25 to 30-year warranty. As the silicon degrades by 0.05% each year, you won’t have to worry about replacing the panels on your narrowboat or campervan.

True: Solar panels work in all weather conditions 

It is common to think that solar panels require the sun to work effectively. However, the panels can work in all weather conditions to generate electricity. When there is no sun, the cloud diffuses the sunlight, allowing for an even distribution for the panels to absorb the light. If there is daylight, the panels will continue to generate power for your houseboat. 

False: Solar panels do more harm to the planet 

A common argument against solar panels is that they’re not environmentally friendly. The carbon footprint of a solar panel is approximately 50g of carbon over the lifespan of that panel. It means it’ll take between two or three years for the panels on your houseboat to become carbon neutral.
