The solar panels are designed to be used with a hot water cylinder so that energy collected from the sun’s rays can be stored and used throughout the day.
In most circumstances, the ideal place for the solar panels is on a south or a south-east facing roof. If that isn’t possible, they can be installed on brackets, that position them at the same angle, for example, on a patio, in a garden or even on a flat roof.
When the sunlight reaches the panels, the heat from the rays is transferred into the water and glycol mixture. This mixture is taken down through a coil into the cylinder to heat the hot water.
Does the UK get enough sunlight to make it worth having?
Worcester Greenskies have been designed to maximise both direct sunlight and diffused sunlight. Also, surveys show that the UK receives 65% solar radiation, the same as Spain do. In the summer you can receive 80-90% of your hot water, and in the winter can still receive between 20-30% of your hot water.
What will the installation look like?
The installation on the roof consists of two panels with a push-fit pipe going in through the roof. Inside you will have a small box installed on a wall that contains the pump. The pump moves the water from the solar panels down to the cylinder and then back from the cylinder to the panels. The clever design of this box contains everything you need including the filling point, pressure gauge, pressure relief valve and expansion vessel. This is all controlled by a control programmer that measures the temperature of the water in the cylinder and also in the solar panels.
Benefits of Solar Hot Water:
- Ability to provide you with around 60% of your home’s hot water.
- Capability to heat hot water in both direct and diffused sunlight.
- Compatibility with either a current gas or oil, Regular or System boiler.
- Low maintenance.
