Preferably, a portion of the photovoltaic module in described new photovoltaic power station system is set separately as air blast
Standby power source.
A kind of new photovoltaic power station system layout method, described photovoltaic power station system include photovoltaic module conventional roof
The building block of photovoltaic plant includes photovoltaic module, wiring, inverter, the building block of header box conventional roof photovoltaic plant；
Described photovoltaic power station system also includes gusseted framework, air blower；Described gusseted framework section
For isosceles triangle, two row's photovoltaic modulies are laid in the waist edges such as two of gusseted framework；
The gusseted framework is placed with the side metal clad thin layer on roof；
Two described row's photovoltaic modulies and the triangulo column that thin metal layer forms a side-closed, two bottom surfaces are opened wide,
The lower end of triangulo column is provided with blast apparatus；
Blast apparatus sets two branch roads, and blast apparatus air intake comes from natural wind, or the interior under roofing, leads to
Cross Valve controlling air-flow source；
Described gusseted framework sectional dimension mainly depending on photovoltaic module size and purlin spacing, considers simultaneously
The flow resistance of air, it is ensured that sectional area reaches a certain size and make it that air circulation and heat exchange are smooth；
The gusseted framework length is depending on roof actual size, the spacing between two triangulo columns, according to
Roof pitch, local latitude, the height factor in gusseted framework section determine that reduction is blocked, and need to ensure that spacing is more than maintenance
Required width.
Specifically, a kind of new photovoltaic power station system layout and method provided by the invention, except conventional photovoltaic power station
Building block, beyond such as photovoltaic module, wiring, inverter, header box, in addition to a gusseted framework, cool down wind
Machine, and some valves, pipeline.Described novel photovoltaic system layout is that its feature exists for color steel tile roof photovoltaic
In：Photovoltaic module is laid not as traditional paving mode close to color steel roofing, but two row's photovoltaic modulies are laid on
On gusseted framework two sides.Gusseted framework section is isosceles triangle, gusseted framework close to roofing that
Side is close to thin metal layer.So, two row's photovoltaic modulies and thin metal layer form a side-closed, three that two bottom surfaces are opened wide
Prism.The gusseted framework of photovoltaic module is paved with, the hollow cylinder of a triangular-section is formd, is set in cylinder lower end
Blast apparatus is put, is introduced air into, is flowed from bottom to top along hollow triangle section cylinder, cooling is played to photovoltaic module
Effect.The gap between photovoltaic module, between photovoltaic module and thin metal layer is filled out as far as possible so that on triangulo column side structure
Closing, it is ensured that air can be with smooth outflow to the triangulo column other end between photovoltaic module and thin metal layer.Blast apparatus air intake
Natural wind is can come from, also may be from the interior under roofing.Two branch roads are set, pass through Valve controlling air-flow source.It is most
When blast apparatus introduce natural wind to be cooled down for photovoltaic module, in most hot season, it is indoor it is general have an air-conditioning, air themperature compared with
It is low, Cryogenic air is extracted out, introduces blast apparatus, is cooled for photovoltaic module, while is also beneficial to the circulation renewal of room air.
Gusseted framework sectional dimension is mainly depending on photovoltaic module size and purlin spacing, while consider the flow resistance of air, really
Guarantor's sectional area reaches a certain size and make it that air circulation and heat exchange are smooth；Gusseted framework length according to roof actual size and
It is fixed；Spacing between two triangulo columns, according to roof pitch, local latitude, gusseted framework section the factor such as height
It is determined that reduction is blocked, need to ensure the width that spacing is more than needed for maintenance in addition.The photovoltaic module output of gusseted framework both sides
Electricity difference, needs individually wiring, and the component ability connection in series-parallel of same direction and angle discharge is confluxed.With south orientation roofing prestige
Power, the photovoltaic module of side is towards the southeast, and for opposite side photovoltaic module towards southwest, both instantaneously export the difference of electricity, it is impossible to
Connection in series-parallel is carried out, wiring can only be carried out towards the photovoltaic module of southwestern (southeast) with other towards the component of southwestern (southeast).
In system of the present invention, the power of photovoltaic module a portion of roofing separately as blast apparatus
Source, photovoltaic module corresponding to blast apparatus are worked when having the sun without energy storage system, and without sunlight then stops, just with light
It is synchronous to lie prostrate component fever time.
In system of the present invention, gusseted framework section is isosceles triangle, highly depending on actual conditions,
Typically it is recommended as between 0.2 meter to 0.4 meter；Base length takes into account photovoltaic module size and roof purlin spacing simultaneously.
In system of the present invention, choosing checks change for convenience, while takes into account roof and utilize area ratio, adjacent
The spacing control of gusseted framework passageway is in 0.5-0.7 rice, the most economy.Can be by selecting photovoltaic module size, adjusting triangle branch
Framework base angle is supportted to change shadow occlusion distance, so as to obtain optimal spacing.
The present invention compared with prior art, has advantages below and effect：System architecture of the present invention causes photovoltaic
Space below component is larger, and introduces active ventilation systems so that ventilation is smooth, beneficial to taking away heat so that and component cools,
And obtain the generating efficiency higher than the arrangement mode of routine.By taking south orientation roofing as an example, photovoltaic module arrangement is in the southeast and southwest
Arrangement, compared to due south direction, it may be such that annual total light income is declined slightly, but the efficiency brought because temperature is relatively low carries
It is high so that gross generation increases, and extends the life-span of photovoltaic module.The shade of gusseted framework just extended to
Road, do not influence to close on the normal work of photovoltaic module, because conventional spread is also required to reserved passageway gap, therefore the present invention provides
This arrangement mode it is compacter than conventional paving mode, the roof space is saved, so as to reduce shared by unit kW photovoltaic modulies
Roof rent.In addition, photovoltaic system structure described in the invention avoids the excessive situation of blast before and after photovoltaic module, resist
Wind is better than the structure that in general inclination angle is put, and is especially suitable for the larger area of wind speed, such as the southeast edge of more typhoons
Haiti area, and there is substantial amounts of color steel tile type The Factory Roof there, and the present invention has more wide application prospect.
