★★★HOW MADE SOLAR PANELS★★★ Each COST ONLY – 100$
——————————————————————————————————————————–
Take a maximum of sun – our problem!
“Solar power” is actually the code name. On the fact that a huge “transistor” is called “Photoelectronic converter” (FEP). From which it becomes clear: how many “photons” it receives (insolation), so can transform an “e”, given its efficiency.
For single-crystal silicon is 17-20%, polycrystalline and amorphous – less than 10%.
Solar polycrystalline modules are a bit cheaper, but the difference is questionable. But the annual loss of capacity due to non-normalized contamination (natural, uncontrolled chemical reactions will rapidly oxidize the substrate), the efficiency tends to zero.
If you get them for 2-3 years, it could still be justified, but if the “always”, then no.
Mounting solar panels by using lokernyh screws or threaded connections in any place of aluminum, profile frame.
Try to orient the solar cells due south. It was coming up from the south “photons” passing air at a right angle, with minimal losses.
Being on the east or west, the solar energy is the atmospheric layers on the diagonal, with a significant loss.
The human eye adapts during the day and it seems that the sun is the same in the morning, afternoon and evening. In fact, the difference in coverage is significant. It will confirm to you any photographer.
Installation angle relative to the horizon for year round use must match the parallel. In St. Petersburg, it’s 60 degrees. Well if it is possible to change the angle, at least twice a year, in spring reduced to 45 °, and in the fall increased to 75 °.
Establish a tracking system, it is impractical because its value is comparable to the price of three solar cells, and the efficiency increases by 40%, and increases the likelihood of failures due to sail in the wind.
In other words, it is cheaper and safer to put two FEP. Although one of our client, a farmer in the Pskov region, fashioned something original with the bike chain transmission and clocks with weights.
Get up in the morning, will be released into the courtyard, and the weights would chip in a chicken coop. Promised to patent, get rich, buy, and roof glazing hens “solar batteries”. Why, I ask? – In the summer air conditioning, winter light is.
With the standard light 1000 W/m2, FEP “digests” of 17-20% is 170-200 Tues
The question is: – Where are the other 800-830 W?
Unfortunately, allocated in the form of thermal energy. And the transistor FEP reacts negatively reduction efficiency for each degree. On a sunny day, heating up to 75 ° C. (The photo is not the best option).
