DIY Solar Panel Kit Prices
East/West three to four person system
£2550 (inc VAT & delivery*)
The triple solar panel water heating system kit containing 3*20 evacuated tubes
should be sufficient for a three to four person home
with an east to west facing roof and average hot water requirements.
Unfortunately 60-tubes on an east or west facing roof are only equivalent to around 36 tubes on a south facing roof (60%).
Placing all panels side-by-side simplifies the system and reduces the overall cost, compared to having one panel on the east facing roof and two panels on the west facing roof.
This DIY Solar Panel Water Heating System Kit includes:
- Three solar panels, each containing 20 high efficiency solar evacuated tubes.
- The panels will be placed side-by-side on the east or west facing roof
- Each panel covers around 2.25 square metres
- Panel dimensions : 1.76 metres (height) * 1.5 metres (width) * 13 cm
- Each double walled evacuated tube is 47mm * 1.5 metres - High efficiency, double insulated, vented solar hot water cylinder (e.g. 206 litres to 250 litres) which will replace your existing hot water cylinder (if you require a less common unvented/mains pressure hot water cylinder, please be aware that these cost around £450 more)
- Copper tubing (with high temperature insulation) required to connect the solar water panel to the cylinder.
- A controller that monitors the temperature at three points: the solar water panel on the roof, the bottom of your cylinder and the top of your cylinder. The controller automatically switches on the water pump when the water in the panel is about 6 degrees warmer than the bottom of the hot water cylinder.
- Other components required to complete the system, including: an expansion vessel, pressure relief valve, pressure gauge, water pump, non-return valves, stop valves and drain valves.
- Solar antifreeze to ensure the water in the Solar Panel Water Heating system never freezes.
A full itemised list of all the components in the kit can be provided upon request
*Some parts of Scotland, Wales and parts of England will incur an additional delivery charge
