How one should not make a solar collector

I start the 2015 season by enlarging the solar collector’s area from 2m2 to 4m2. Roof slopes of my house are situated to the East and to the West. The initial plan was to raise the solar collector in such a way that it would be situated to the South.

One section of the collector (2m2) has been heating water for 3 seasons. The collector was situated at 120 centimeters distance from the wall. In order to situate it at 45° angle I would have had to move it at 160 cm distance from the wall. And if I wanted the 30 cm. of protruding roof not to cast a shade upon the collector too early, I would need to move the collector even at 190 cm. distance from the wall… This would mean complex holding construction. Having evaluated future troubles with servicing, I chose the simplest way and put the collector on the ground. There is a 22 meter pipe distance from the collector to the boiler. A solar panel charges 12V 7Ah battery. The system has a 12V pump, which has worked fine for 3 seasons. The collector now looks as follows:

The frame holding the collector is quadrangular, as I will have to remake it when I have a chance. After 3 seasons polycarbonate covering turned a bit yellow, even though the collector itself is holding well. Aluminum pipe connections are watertight. On a sunny day, when I blocked the end of lower pipe and filled the heat exchanger piping with water, all the water in the heat exchange reached the boiling point and evaporated.

    O kaip apie visą sistemą? Labiai išsamiai aprašoma apie įvairiausius saulės kolektorius ir saulės šilumos kaupimo sistemas:) Bet kaip apie prie saulės kolektorių statomas šilumos kaupimo sistemas. vandens boileris, gerai pajungtas į sistemą gali parodyti visą saulės kolektorių potenciąlą.

    Taip del paprastumo ir lengvumo sutinku tik ar krinta efektivumas del mazesnio sviesos pralaidumo? Ir kaina pigiau nei stikla naudoti?

    Pavadinta taip, nes manau, kad iškėlimas į namo skliautą buvo klaida. Per daug sudėtinga tvirtinimo konstrukcija, per mažas pakrypimo kampas.
    Polikarbonatu nenusivyliau. Pavasarį planuoju padaryti 2 keturkampius kolektorius, užimančius mažiau vietos ir dengsiu 4 arba 6 mm polikarbonatu. Dėl paprastumo ir lengvumo.

    Kodel pavadinimas ,,kaip nereikia daryti,,? minusu nepaminejai kaip ir? Man idomu del polikarbonato kokie pliusai minusai naudojant vietoj stiklo? Pas mane stiklas jau trecia sezona, seip viskas tvarkoj tik kai reikejo nukelt stikla vargo buvo, su polikarbonatu butu paprasciau beto jis maziau ir silumos isleistu, bet skaidrumas mazesnis. Tai gi kas geriau butu pagal efektivuma?
