How to make a solar panel for a solar shower in just ten easy steps....

Similar solar panels cost more than £1000 and are between 90% and 95% efficient. Ours will cost you nothing. Its about 50% efficient, but that is still good enough to make piping hot water even in the UK.

Just follow our simple step by step instructions and you could be the proud owner of a solar panel that can make gallons of hot water per day for free!

How to make a solar panel for a solar shower:

The solar panel
1 Get hold of an old central heating radiator. Take a look in skips around the streets of your neighbourhood or at your local tip or recycling centre. This just needs to be an ordinary flat house radiator.
2 Paint it with black paint.
3 Get hold of some fibreglass loft insulation or old emersion tank lagging. You will probably be able to find these dumped in skips too.
4 Put the insulation or lagging into the bottom a box made out of wood. The box needs to fit the size of your radiator, with a wooden bottom and sides about 20 to 30 cm deep.
5 Place you black radiator on the insulation inside your box and attach a piece of glass or clear plastic on the top of the box.
Similar solar panels cost more than £1000. You have just made you solar panel for free!

Your panel will heat about 12 litres of water for every square meter of panel. If the radiator that you started with was 1 meter by 2 meters, that’s 24 litres of hot water per day.

The hot water tank
1 Get hold of a something that will be your tank. The best thing is an old insulated hot water tank saved from a skip.
2 Your tank needs to be mounted about 1 meter above your solar panel.
3 Connect a tube, hose or pipe from the bottom of the tank to the bottom of the panel. This is also where you need to connect a tap or a shower head.
4 Take a tube, hose or pipe from top of the tank to the top of the panel.
5 Add water and sun.
The cold water from the tank will sink to the bottom of the panel, as the sun shines and heats it, it will rise go into the top of the tank, the cycle repeats meaning that no pump is required.

At the end of the day, when you feel most sweaty and dirty, the water will be ready for your shower. Enjoy!
