How to Make DIY Solar Heating Panels
Making DIY solar heating panels can be pretty simple, as long as you prepare the materials you need for the project. Anyone with average handyman skills should be able to easily complete the task, and special tools are not required.
All you need, in terms of equipment, are:
* a wood saw
* a hacksaw
* a drill
* a screwdriver
* a hammer
* screws
* nails
* a file
* a paintbrush
* a tape measure
Materials you need to procure include the following:
* a 10mm annealed copper tube
* a 16swg aluminum sheet
* glass fiber wool
* a marine-ply sheet
* 4mm glass
* timber for the frame
The copper tubes will be used to bring the water through the collector area. Copper has high thermal conductivity which makes it perfect for the job. It's available in most plumbers' shops, and comes in 20m, 25m, and 30m coils.
Once you've assembled the copper tubing, you'll attach it to the blackened absorber plate. It will collect the sun's heat and transfer it to the copper tubing. It is recommended to use aluminum as an absorber plate because it is cheaper than copper sheets and it is more readily available in most locations.
The absorber plate will be encased inside a wooden frame. It is made from hardwood, with a marine-ply backing sheet. If you want the frame to last longer, have a preservative coating applied to it. This will add a couple of years of service.
The last part of the DIY solar heating panel is the transparent cover. This will prevent heat loss especially during cool weather. Glass is preferable because of its high light-transmission value. If you can't afford a float glass, acrylic sheeting should be a suitable substitute. The downside of using acrylic sheeting is that it can be prone to scratching and discoloration.
The efficiency of DIY solar heating panels might not be as good as the efficiency of commercially available ones, but they can get good results. And imagine of the savings you can get when you make one. A DIY solar heating panel costs a third the price of a commercial one. Not only that but you'll be cutting down your energy bill as well if you use it. If constructed right, the panel has a life expectancy of twenty years. There are no moving parts involved, and no maintenance should be required the panel.
Constructing DIY solar heating panels is not complicated and is one of the easier DIY solar power projects. This is one project that you should definitely try if you are interested in setting up DIY solar power equipment or systems. You can use the panel to heat your pool, or to supply your home with hot water.

QUESTION:
'Need service providers to use our pool heating solar panels for other use?
Hi,I live in San Ramon, CA. We have a nice set of solar panels, which we have been using for heating our pool. Is there a way that those solar panels can be used for house hold water heating instead of heating the swimming pool OR can they be traded for installing a new set of PV electricity useful panels to producing electricity.
Pls get in touch with estimate and suggestions.
Best regards.

QUESTION:
Anyone know how to make solar panels for heating water?
Or where to find the cheapest. I am building an outside toilet are to be encased in a porch. I want the water to be totally solar heated and might want use underfloor heating from the same source.
Forgot to say I am UK based-
ANSWER:
If you want to build your own, check out Build it Solar, http://www.builditsolar.com/. They have lots of ideas for making your own solar water heating panels. You'll need to also have a tank to store the water. Since it is possible to get freezes in the UK, you will likely have to do a closed loop system that has an antifreeze in it to prevent freezing. That gets to be a more complex system involving a heat exchanger, so you may want to buy that system rather than make it.You can also run radiant floor, wall, or ceiling panels to use that water to heat the room, I'm heating my house in New England with solar heated water. http://www.altestore.com/gallery/Amy-Beaudet-gallery/v/9358727169/amys_water/ I don't need to tell you that the UK isn't the greatest location for solar, so I don't know if you'll be able to achieve your 100% goal.
Here's a site that discusses solar water heating in the UK, http://www.energysavingtrust.org.uk/Generate-your-own-energy/Solar-water-heating. Since they are heavy, it can be expensive to ship, so you are probably better off buying locally.

QUESTION:
What's the difference between a proper Solar water heating panels?
and household radiators painted black and housed in a cloche. Being a tight git I built my Solar water heating system for £180. It's three 1.2m x .6m panels, a pump and a controller. It gives me tons of hot water on a sunny day and does a bit even when it's not sunny. So whats the difference? Why do people spend £7000 on solar water heating systems?-
ANSWER:
"Cloche" as in belfry? (In your case inhabited by bats.) Solar panels do more that just heat water, they also supply electric current. I use my solar shower all the time while backpacking. Just fill the plastic bag with water (the back of it is coated to absorb the sun's rays), lay it on a rock out in the sun, and 4 hours later hang it on a tree limb, attach the shower hose and head (god that sounds obscene somehow), and you got a 5 minute hot shower. Nothing wrong with being frugal, but a tight git is something else.

QUESTION:
I am installing a Combi-boiler. Is it possible to link this with solar heating panels to preheat the water?
I have just been hit with an exceptionally large bill form my power supplier. This is even after we kept asking our provider if it would cover the expense. Each time they told us yes.
So bit p****d off.
Any thought or relevant information would be greatly appreciated.
Thank you in advance-
ANSWER:
OK but be careful, have you got a corgi registered plumber to fit the boiler or are you actually fitting it yourself then you need to get someone to commission it for safety reasons.
