Скачать или смотреть Cheap solar collector for 40-70 ºC (its construction, cost of heat)

I made this solar collector a year ago, and you may mistakenly think that it is a cheap copy of these very expensive solar collectors which have this dark metal sheet to absorb solar radiation and convert it into heat, and the thermal conductivity of the metal sheet carries the heat to these copper pipes for a liquid that takes the heat.

This cheap solar collector has a different design, and this thin steel sheet is heated by the sun and gives the heat to water which will move along these holes within a similar polymer sleeve, and we understand that such cheap polymer sleeves replace those expensive copper pipes which require laborious connection of the pipes with each other and with that dark copper or aluminum sheet, and these facts affect the profitability of such large solar stations designed to produce a huge amount of heat which should be cheaper than heat from natural gas or other traditional energy sources.

We may notice that the weight of the water presses well those polymer sleeves to the inner surface of the hot steel sheet, and therefore it transfers the heat very well to the water, and this video will show these results of my measurements of the energy parameters of my solar collector.

This is one of my experiments, and the water of this tank is moved by this pump to the inlet of the solar collector, and now each of the five polymer sleeves has a separate outlet because I wanted to be sure that the water flow through each of the five sleeves is about the same.

Now I am showing how this solar collector has heated 42 liters of water of the tank from a temperature of 17 degrees to 65 degrees Celsius for three hours.

So, let's compare the cost and energy capabilities of this solar collector with these expensive collectors.

These are my costs of materials for the collector, and we can calculate that it is about 12 dollars per square meter, and this is approximately 10 times cheaper than these flat plate solar collectors, however we understand that these costs do not take into account the salaries of workers, and this is the minimum version of the collector, similar to the way the minimal version of Tesla Model 3 has a price of 35 thousand dollars, but we know that usually model 3 sells for 40, 50 or more thousand dollars, and the minimum version of our solar collector is the following.

We see that the body of my solar collector consists of expanded polystyrene and wooden battens, however I think that many of you may offer a large number of other versions of the collector body with mineral wool and metal or polymer sheets, or thin sheets of wood based. In addition, this thin steel sheet of the minimum version is coated with cheap black paint and not with a selective coating. These upper and lower walls of the minimum version of my collector are wooden boards with primitive fixation on the collector body, and these are sheets of ordinary cheap glass, and their primitive fixation and sealing of their joints will be described at the end of this video.

These wooden parts fix the collector on the ground, however we understand that more expensive versions of the collector can replace these wooden stakes with more reliable structures based on concrete or steel.

Now I am showing the construction of a large solar station with expensive flat-plate solar collectors, and this is the work of the Danish company Arcon-Sunmark which constructs solar stations is radically cheaper than its competitors, and therefore this company is the world leader, and it constructed almost all the large solar thermal stations, including this station to produce heat for a copper plant in Chile and this station for district heating of the Danish city of Silkeborg.

We see workers installing large solar collectors on small steel columns, and then adjacent collectors connect with each other, and the edges of a collector row are connected to large pipes for heat transfer agent.
