Solar Thermal Panels

Solar Thermal Panels are a superb green solution for providing hot water to your home. They qualify homeowners for the domestic Renewable Heat Incentive (RHI) scheme, meaning that you can benefit financially whilst helping the environment.

Firstly the sun heats the solar collector, and fluid is pumped to a solar coil within your hot water tank. Heat is then transferred to water in the tank and is made available for your family’s hot water needs. Solar Thermal Panels cover over half of your annual domestic hot water needs including shower, tap water and bath water. This significantly reduces your energy consumption and limits the daily workload of your boiler system.

Solar Thermal Panels can be integrated with existing hot water systems, and paired with an ultra-renewable Biomass Boiler for optimum performance. Franck Energy will manage your project from start to finish, ensuring your Solar Thermal Panels are installed quickly, correctly, and according to regulations. We help you go green and save money, without any fuss.

Solar Thermal Panels FAQs

Where can I place Solar Thermal Panels?

The table shows the solar yield over the year depending on collector tilt and orientation (90 ° = vertical). Solar panels are placed first on the existing roof with minimum inclination of 20 °. Vertical mounting on the wall is also possible. If you choose not to mount to a roof or wall, the solar panels must be installed at a 45-60 ° inclination. South-facing is the ideal placement for a solar water heater. Solar panels facing east or west are missing out on some of the solar energy in spring and autumn, but in summer there is not much difference with the south-facing solar panels.

How does Solar Thermal work?

A solar water heating system uses heat from the sun to warm the water in your home's hot water tank. This is achieved by attaching a variety of solar panels called solar thermal collectors to the roof of your building. The panels contain a heat-transfer fluid – a mixture of water and antifreeze – which circulates within the panel and absorbs the sun’s heat. An electronic pump causes this fluid to circulate from the panels to a hot water cylinder, where a heat exchanger transfers the heat to the mains water.

How much do a Solar Thermal Panels cost?

Advances in technology have made it possible for everyone to make use of solar energy in heating and powering their homes. Average systems cost between £3,900 for a two person household to £5,000 for a six person household. Using a solar thermal system makes a positive contribution to the environment as it employs renewable solar power and reduces the amount of heat generated through the burning of fossil fuels, thereby also reducing CO2 emissions and other knock-on effects.

How much space do l need for a Solar Thermal system?

Solar thermal systems are compatible with most conventional water heating systems, as long as you have a hot water tank. They require very little maintenance, although an annual service check is recommended. Before buying a system you should consider whether you have space for the necessary components. In particular, you need 5 square metres of roof or wall space on a surface that receives sun exposure in order for the system to be most effective. You will also need some space with access to your hot water tank to install a solar cylinder to heat the water.
