Technical field
The utility model relates to a kind of photovoltaic generation equipment, particularly relate to a kind of without convergent belt string and composite type photovoltaic module, be made up of materials such as glass plate, metal framework, polysilicons, and the photovoltaic module without built-in convergent belt in parallel after the series connection of inner silicon cell piecemeal.
Background technology
Nervous at traditional energy, price raises, and under the background that environmental problem becomes increasingly conspicuous, solar energy has very large energy-saving potentiality and the market space as the most clean, reproducible new forms of energy.According to " 12 planning ", within 2015, China's photovoltaic generation total installation of generating capacity will reach 40GW, but compared with traditional water power, thermoelectricity, the shortcomings such as photovoltaic generation still exists randomness by force, power supply reliability difference.
Traditional photovoltaic generating system is formed primarily of photovoltaic module and grid type inverter, wherein photovoltaic module is made up of multiple silicon units in series, solar energy is converted to the direct current energy with certain voltage grade, the DC bus that always confluxes of photovoltaic module outputs to solar inverter.Silicon unit in traditional photovoltaic module adopts series topology structure, once the situation such as in photovoltaic module, part silicon unit breaks down, covers, sunshine is not enough, can because the reason of circuit connected in series, other silicon unit is limited to abnormal silicon unit and can not exports maximum power, this directly causes this series arm cannot effective power output, has influence on whole series component simultaneously.In addition, conventional photovoltaic electricity generation system realizes the maximal power tracing MPPT of photovoltaic generation in main convertor, and the optimal power that cannot realize single photovoltaic module exports and intelligent management.As above-mentioned known, there is certain barrier problem and cannot solve in conventional photovoltaic assembly.
Summary of the invention
The utility model object is to provide one without convergent belt string and composite type photovoltaic module, is made up of materials such as glass plate, metal framework, polysilicons, and the photovoltaic module without built-in convergent belt in parallel after the series connection of inner silicon cell piecemeal.
To achieve these goals, scheme of the present utility model is: a kind of without convergent belt string and composite type photovoltaic module, comprise outer gimbal support, photovoltaic lamella, daylighting glass plate and bottom backboard, photovoltaic fin laminating is attached on bottom backboard, daylighting glass plate is arranged on the surface of photovoltaic lamella, outer gimbal support is a rectangle frame, rectangle frame is by photovoltaic lamella, daylighting glass plate and backboard frame are lived fixing, wherein, photovoltaic lamella is longitudinally nine photovoltaic fin orders arrangement, it is laterally the distributed architecture of four rows, mutually connect at nine photovoltaic fin both positive and negative polarity lead-out wires of described photovoltaic lamella longitudinal arrangement, described bottom backboard is provided with wire delivery outlet, lead-out wire after series connection is drawn from wire delivery outlet, electricity is in parallel mutually for laterally four row's series line of drawing.
Scheme is further: described bottom backboard is provided with one deck EVA adhesive film, and photovoltaic lamella and bottom backboard bond together by described EVA adhesive film.
The beneficial effects of the utility model are:
(1) eliminate the erection space that traditional bus-bar increases photovoltaic cell, improve the energy output of unit are;
(2) overall structure is simple, making is easy, is convenient to integral installation, promotes;
(3) do not changing on the basis of polysilicon raw materials, total generating capacity improves 10-20%;
(4) situations such as breaking down at part silicon unit, cover, sunshine is not enough, a partial interior component string is run abnormal, and other does not receive impact, relative to general components now generating efficiency raising 20-50%;
(5) as some silicon unit damages after using a period of time, can directly ignore this component string, the impact of original equipment efficiency is reached minimum.
Below in conjunction with drawings and Examples, the utility model is described in detail.
