Description

Crystalline Silicon PV Module

Technical field

The utility model belongs to field of photovoltaic technology, relates to a kind of Crystalline Silicon PV Module.

Background technology

Solar energy is the regenerative resource that the mankind are inexhaustible, nexhaustible, any environmental pollution can not be produced, in effective utilization of solar energy, photovoltaic technology progressively enters daily life, wherein, the crystal silicon solar energy battery of extensive use utilizes Crystalline Silicon PV Module to absorb luminous energy exactly, opto-electronic conversion occurs thus produces electric energy.It is 60 and 72 that the general cell piece quantity of photovoltaic module is produced in current design, power is 290W to 320W to the maximum, product power is discontinuous causes customer selecting inconvenience, such as will be forced to when client needs the (PCC) power of about 280W select more high-power assembly, cost is not only caused to increase, and need amount owing to adopting more high power component to cause general power to exceed, system matches performance is restricted.

Summary of the invention

There are the problems referred to above for existing technology in the utility model, proposes a kind of Crystalline Silicon PV Module, and this Crystalline Silicon PV Module compensate for the vacancy of current product, facilitates client to carry out power match.

The utility model is realized by following technical proposal: Crystalline Silicon PV Module, it is characterized in that, comprise the isolation notacoria layer, the first isolation EVA layer, battery layers, the second isolation EVA layer and the glassy layer that are cascading, described battery layers comprises six string battery strings, described battery strings of often going here and there is connected mutually by 11 cell pieces, often going here and there described battery strings two ends arranges positive pole, negative bus bar respectively, and the odd number string battery strings be arranged side by side is contrary with busbar two bipolarity at even number string battery strings two ends and connect successively.

In above-mentioned Crystalline Silicon PV Module, being provided with main gate line between described adjacent two string battery strings, described main gate line being provided with the location adhesive tape one for pasting about two adjacent cell sheets.

In above-mentioned Crystalline Silicon PV Module, described location adhesive tape length direction is vertical with battery strings main gate line.By such setting, adhesive tape two ends, location are contacted with cell piece more, better can ensure the direct stability of adjacent cell string.

In above-mentioned Crystalline Silicon PV Module, described location adhesive tape length of interval is 15mm-35mm.

In above-mentioned Crystalline Silicon PV Module, described glassy layer is matte safety glass.

In above-mentioned Crystalline Silicon PV Module, described Crystalline Silicon PV Module surrounding is fixed by aluminium section bar.By aluminium section bar, crystal photovoltaic assembly surrounding is fixed, play a protective role.

Compared with prior art, the utility model has the following advantages: the form that have employed 6 * 11 arranges cell piece, to obtain a kind of novel Crystalline Silicon PV Module, and makes its power between the rated power of existing product, enrich product line, facilitate customer selecting.

Detailed description of the invention

Be below specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.

As shown in Figure 1, Figure 2, Figure 3 shows, this Crystalline Silicon PV Module, comprise the isolation notacoria layer 1, first be cascading and isolate EVA layer 2, battery layers 3, second isolation EVA layer 4 and glassy layer 5, battery layers 3 comprises six string battery strings, battery strings of often going here and there is connected mutually by 11 cell pieces 31, often going here and there battery strings two ends arranges positive pole, negative bus bar 34 respectively, and the odd number be arranged side by side row battery strings is contrary with busbar 34 liang of bipolarities at even rows battery strings two ends and connect successively.

As shown in Figure 4, specifically, main grid 33 is provided with between adjacent two string battery strings, main grid 33 is provided with the location adhesive tape 32 for pasting about two adjacent cell sheets 31, it should be noted that, location adhesive tape 32 length direction is vertical with battery strings main grid 33, and location adhesive tape 32 1 length can be 15mm-35mm, as preferably, usually adopt the location adhesive tape 32 that 20mm is long.

Prevent busbar 34 from coming off, can also arrange location adhesive tape 32 on busbar 34, locate adhesive tape 32 and paste in miter angle with busbar 34, by being obliquely installed location adhesive tape 32, the contact surface of locating adhesive tape 32 and busbar 34 is increased, locating effect is better.

In order to enable Crystalline Silicon PV Module surrounding fix, Crystalline Silicon PV Module surrounding is fixed by aluminium section bar.

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
