Leeds Solar Heating panels

On-The-Roof Solar Hot Water Systems.

This type of system enables collectors on the roof to collect the radiant heat of the sun. There are 2 main types of domestic collector

1. The traditional flat-plate collectors. (Looks like a flat plate and can be seen in the picture to the right)

2. Advanced evacuated tube systems (In tubular form and can be seen in the picture to the left).

Hi-Tec Vacuum Tube Panels

These absorb upto 93% of the sun’s energy with minimal heat loss, leaving them unaffected by factors such as wind chill or ambient air temperatures. This is because of their unique vacuum structure which allows them to absorb whatever solar energy is available even on cold or dull days. This design means that there is the possibility for your heating system to provide you with hot water for up to 8 months of the year and aid your existing water heating during the colder winter months.

How does it work?

The solar panels are mounted on the roof and absorb the heat from the sun's rays, transferring the heat to a fluid.

The heat is transferred to the stored water and then returns to the panels to be re-heated and continue the process.

The fluid is circulated from the panels through to a special solar coil in the base of the hot water cylinder.

Further Information

How much hot water can the solar system generate?

During summer, solar panels/tubes can generate up to 100% of the domestic hot water needed for a typical household. In the winter months, as much as 30% can be generated and then remainder is then provided either by a conventional boiler or electric immersion heater.

On average, a solar hot water system can generate around 50-60% of a households domestic hot water requirement per year.

How many solar collector panels will I need?

The number of solar panels or tubes required, relates to the size of the solar cylinder.

The size of cylinder required is dependent on:

•the number of people in the household
•the amount of hot water required daily for baths, showers etc.
•number of panels may also depend on available roof space.

Key features and benefits

•Solar power can reduce hot water heating costs by up to 60%** annually
•Low environmental impact: can reduce carbon emissions by around 400kg per year (depending on the fuel replaced)
•can be link with traditional heating systems

** Savings are dependent upon type of solar system used, location and usage patterns

If a solar hot water system in installed in a property, you may receive a higher rated Energy Performance Certificate in line with the Government's new Home Information Packs.
