solar panels producing hot air
Who does have experiences with these products? They are cheap , but i want to be sure that can produce heat as they substain !

solar panels producing hot air
Today i finished my installation. (pictures will come in next days). I turned on the panel (is solar powered) in a shiny day. Ambient conditions were: at 11.00 AM , temp. = 14 C, humidity (H.R) = 43%. After 2 hours (13.30 PM) , air coming out from panel was temp = 33C , H.R =20% (ambient conditions were nearly the same of 11.00 AM). Tomorrow is going to rain , so i must wait for a complete shiny day to collect other data to test if temperature can even increase. H.R is really good (very dry). Take note that my will is to reduce HR in the basement. Cheers.

DIY solar panels producing hot air (2)
Hi my friends, i did this topic here for a commercial panel.
Today after some DIY days i want to present you my own panel , made with alluminio , beer cans and polycarbonate .
Weight is <8 kgs !
My temp. measure of today : windy, full sunshine (PANEL IS NOT YET FINISHED , lack of lateral isolation and exit pipe is not isolated and connected with tape.... it's just to test )
outside air temp °C panel outflow air temp °C
17,6 72,9
18,8 75,4
see my video on youtube

Re: solar panels producing hot air
Looks like a fun project!
What do you us to suck/blow the air, or does the temperature difference do this by itself?

Re: solar panels producing hot air
12 cm pc fan , that "makes" 80 CFM = 135,93 m3/h
fan is , for today powered by a 12v psu, but i have a ready to use photovoltaic panel (10watt) to mount aside the air-panel

Re: solar panels producing hot air
I'm definitely going to have a go at this project (small version 1st)
What are you using as a 'lens' ?

Re: solar panels producing hot air
i spent a week on deciding which panel (front vs. sun i mean) , you know i'm a chemist , so i gave a look at many different panel and studied their most important features like light transmission, heat block (once inside the structure), uv-resistant , moisture absence , cells size and numbers (every pannel has many small internal cells), weather resistance ect etc. and PRICE !
the best, is (at the moment):
LEXAN THERMOCLEAR UV RESISTANT .
Please note thermoclear , because there are many many different types , thermoclear is the good one for solar panels
The problem of this first DIY is the chassis : here the panel are glued and then blocked using alluminium angle-profilates , the best would be to find a modular system (alluminium) where you simply insert the panel in the groove. something like this

Do you have any ideas (web sites) for this?

Re: solar panels producing hot air
The sun is going down , the top result has been
ambient : 22 C (wow like end of summer )
panel outflow : 90 C !!!

Re: solar panels producing hot air
I have some friends who work in the alluminium industry. I'm going to ask theme if they know something like this.drmacchi wrote:The problem of this first DIY is the chassis : here the panel are glued and then blocked using alluminium angle-profilates , the best would be to find a modular system (alluminium) where you simply insert the panel in the groove. something like this

How deep does it need to be?

Re: solar panels producing hot air
dimension is relative : i mean as bigger is, as more heat could generate. then we must consider the can dimensions : mine are 0.50 lt of beer (oh oh this summer i drunk 224 cans = 112 lts ) and are 17 cms tall.
you must think what dimension you need and then calculate how many can-columns and how tall.
mine are 16 columns with 14 cans each

Re: solar panels producing hot air
Just thinking about the outer case/shell.
Is it not better if this was made from wood to keep all the heat inside?

Re: solar panels producing hot air
wood was first idea , simple to buy and to construct.
but it's heavier , you must carry it on your roof...
years of water , snow , wind, sun outside : you must repaint it every "x" years and be careful to not paint the front face.
Alluminium is better, just my 2 cts.

Re: solar panels producing hot air
This is great! How much were the costs of all the materials?
(don't count the beer cans of course, cause I guess you had a lot of fun emptying those )
