Solar thermal panels have become very popular in recent years, with heat and hot water accounting for around 60% of the average energy bill. The solar system you opt for in your property will depend on a number of factors such as your average hot water usage, the amount of roof you have available and your central heating system.
It’s estimated that around one square metre of panel is needed for each person in the household and this would account for between 30 and 60 litres of water tank volume.
As with any home improvement it’s always recommended to do plenty of research which is what this article and site aim to help you with. Consumer watchdog Which? revealed that dodgy salesmen and sales tactics could be exaggerating savings and earnings so always choose a reputable installer.
Types of solar water heating systems
There are two main types of solar water heating panels: ‘flat plate’ and ‘evacuated’ tubes (referring to the way in which water interacts with the panel). Evacuated tubes are more efficient than flat-plate versions, so are often smaller but generate equal amounts of hot water.
There are also ‘drainback’ systems. These drain water from inside the solar panel when the pump is switched off to prevent water freezing or boiling inside the solar panel.
Pros and cons of a solar water heating system
Pros
- Solar thermodynamics can save you hundreds of pounds each year by producing free, environmentally friendly heat for space and water heating
- As National Grid prices continue to rise each year, you’ll save more and more over the 20-year life expectancy
- Earn a Government backed income for the energy you produce with the Renewable Heat Incentive (RHI), which pays out for seven years
- Benefit from a grant in the Renewable Heat Premium Payment scheme to help fund the initial costs
- There are virtually no maintenance costs and they’re known as a fit and forget technology. You’ll even have a warrantee between five and ten years.
Cons
- Solar water heating panels won’t produce electricity and you’ll need a PV system for this
- You’ll need to ensure your roof can support an installation
