Solar panels with their own hands - high-tech in your home

Solar hands - assembly principle

solar cell - module, which is a series-parallel connection of a plurality of elementary diode semiconductor junctions grown on a special technology in the factory on silicon wafers with a side of an average of about fifteen centimeters (though there are differentSingle crystals of larger area), about half a millimeter thick and weighing up to seven grams.

of them can be quite simple and easy to make your own hands solar battery power required, a reliable and long-lasting source of power and save quite a considerable (on average four times cheaper) funds for the acquisition of similar industrial products.

described solar cell - unit - can give up to eight operating current Amps at a voltage of just over half of the Volt, which is the power of up to four watts.Homemade solar battery connection is dialed a few dozen of these modular elements, as a rule, for one panel is used about thirty-six plates.For interconnecting elements on the outer and rear surface of each pad has a track or providing contact connection.

Usually they are made by applying different ways (spraying) metallized composition comprising silver and easily propaivayutsya conventional soldering iron.

general principle of modularity is essential for solar cell.This increase capacity of the power source can be gradually, which is important, given the still high cost of plate modules themselves.Before the house to make a solar cell, it is necessary to mention that the cost of solar cells annually falls, respectively, reduced the terms of their return on investment.The quality of plates (even made in China) increases.

Homemade solar panel - acquire components

process itself and the result will bring real satisfaction when the solar panel with your hands will be collected, the designer of the "do it yourself" (which includes all the main necessary elements of design) is offered by many websites and specialty stores.

way to acquire a kit comprising in addition to the special flat plate conductors and blocking diode, certainly more profitable than finding components separately.It is necessary to take into consideration the probability of the "battle" of solar cells due to the high brittleness of silicon wafers, so buy them better with a small margin (couples should be enough).

Before you make a solar panel, you need to buy above the minimum set, think about the design of the protective box with a transparent front part of the plate to protect against possible external action of natural and man-made factors.To this end, experts advise to use Plexiglas or organic glass.Less than recommended, but is also often used ordinary glass.Not recommended polycarbonate.

a box-like structure manufacturing technology should provide it sufficient stiffness, protection and sealing plates exclude condensing inside the volume.There are practical to apply a colorless silicone sealants, which can also be purchased together with other components.

How to make a solar cell - key steps in making

So, collected solar cell with his hands, a diagram of which is a series connection of the plates, must take into account the thermal expansion of the materials.Therefore, between the elements you need to leave a gap of at least five millimeters (convenient to use standard wall crosses for ceramic tile laying).A plate and the conductors themselves must be firmly fixed on the basis of the entire rear surface in order to avoid breakage and cracks.

for soldering wires to the aforementioned platforms (tracks), you can use special solders and fluxes, quite suitable alcohol solution of rosin and "silver" solder.More details will show how to make solar panels with their own hands, the video at the beginning of this article, with all necessary devices and circuit components (charge controllers, plate, blocking diodes, substrate, and compounds).

Just remember, connecting plates with each other, that the front side - the "positive" cable, back - "minus".That is soldered onto the front side of one plate conductors are connected to the corresponding contacts on the back of the next.The corresponding rows Wire plate elements between a fixed conductor of the broader package.

If the two plates to connect the same side, you get a new element with twice the operating current.Accordingly, vosmiampernye two plates connected in this manner form shestnadtsatiamperny module.Through these experiments, remember sectional conductors, thermal mode, plates and their fragility, take appropriate safety measures.
