The utility model provides a kind of high withstand voltage solar module, comprise front glass sheet, backboard, be packaged in the battery unit between front glass sheet and backboard and be arranged at the connector at the backboard back side, cable and terminal box, distance between described battery unit edge and header board glass edge is not less than 11mm, and in described terminal box, embedding has insulation silica gel.The utility model can make each module matrix connect more assembly, decrease the direct current cable use amount being connected to inverter, corresponding quantity and the line loss decreasing header box inverter, adds output electricity, reduce system cost, very helpful to raising investment return.
Description
Technical field
The utility model relates to solar module technical field, specifically a kind of high withstand voltage solar module.
Background technology
At present, IEC standard solar power system maximum voltage general is in the industry 1000V, which limits the quantity of module matrix series component.The more assembly if each module matrix can be connected, the use amount so receiving the direct current cable of inverter will reduce, and the quantity of header box inverter is also by corresponding minimizing, and line loss minimizing can increase output electricity, very helpful to raising investment return.But the assembly of series connection is more, and system voltage is higher, this just needs the voltage endurance capability improving solar module.
In a few years from now on, high-voltage battery assembly will become development trend.Europe has set about improving corresponding testing standard successively, International Electrotechnical Commission (IEC) is after the preparation of 2 ~ 3 years, be about to release the more new standard being applicable to 1500V system voltage, to this, TUV SUD has also put into effect the authentication service for the auxiliary material of 1500V assembly in time as world-famous Third Party Authentication mechanism, and pays close attention to follow-up change and revise to adjust Valuation Standard.
After improving system voltage, mean and obviously can reduce system cost, reduce the loss of transformation end, shorten length of arrangement wire thus reduce line loss, therefore, releasing high withstand voltage solar module and product will be made to have more the market competitiveness.
Utility model content
The purpose of this utility model is to provide a kind of high withstand voltage solar module, system voltage is brought up to 1500V by 1000V, increases and export electricity.
The technical solution of the utility model is:
A kind of high withstand voltage solar module, comprise front glass sheet, backboard, be packaged in the battery unit between front glass sheet and backboard and be arranged at the connector at the backboard back side, cable and terminal box, distance between described battery unit edge and header board glass edge is not less than 11mm, and in described terminal box, embedding has insulation silica gel.
Described height is withstand voltage solar module, the backboard of the voltage of resistance to 1500V selected by described backboard, and the connector of the voltage of resistance to 1500V selected by described connector, and described cable selects the cable of the voltage of resistance to 1500V, and described terminal box selects the terminal box of the voltage of resistance to 1500V.
As shown from the above technical solution, the voltage of solar cell system can be brought up to 1500V by 1000V by the utility model, each module matrix is connected more assembly, decrease the direct current cable use amount being connected to inverter, corresponding quantity and the line loss decreasing header box inverter, add output electricity, reduce system cost, very helpful to raising investment return.

Embodiment
the utility model is further illustrated below in conjunction with accompanying drawing.
As shown in FIG. 1 to 3, a kind of high withstand voltage solar module, comprise front glass sheet 1, backboard 2, be packaged in the battery unit 3 between front glass sheet 1 and backboard 2 and be arranged at the connector 4 at backboard 2 back side, cable 5 and terminal box 6, backboard 2, connector 4, cable 5 and terminal box 6 all high pressure of resistance to 1500V.Distance d between battery unit 3 edge and front glass sheet 1 edge is not less than 11mm, improves electrical safety distance; In terminal box 6, embedding has insulation silica gel 7, to increase creepage distance.
Compared with the solar module of existing 1000V, adopt solar module of the present utility model, the component count that module matrix can be made to connect increases by 50%, as shown in Figure 4.The component count of each module matrix increases, when same installation amount, the quantity of module matrix reduces, because all component matrix all will be flowed to header box, the minimizing of module matrix quantity just means that header box quantity reduces 50%, module matrix, to the number of cables also corresponding minimizing 50% of header box, saves cost, as shown in Figure 5.The minimizing of number of cables, the electrical loss of cable also can reduce, thus improves overall generating efficiency.
The above execution mode is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that claims of the present utility model determine.
