In the area that sunlight is abundant, a large amount of resident builds photovoltaic power generation apparatus on oneself roof.Under country supports electricity generation grid-connecting energetically, realize roof photovoltaic power generation apparatus and national grid is grid-connected seems very important, and under limited resource, how to improve new particularly important of generating efficiency.
Utility model content
The utility model provides a kind of photovoltaic generating system to solve the problems of the technologies described above, and it realizes the grid-connected use of family expenses photovoltaic generating system and national grid, and effectively can improve generating efficiency, improves income.
The technical scheme in the invention for solving the above technical problem is:
A kind of photovoltaic generating system, comprise roof photovoltaic module and the support for fixing roof photovoltaic module, described roof photovoltaic module comprises the solar array connected successively, DC-DC converter, filter circuit and inverter, described inverter is connected with electrical network link with domestic loads link respectively by diverter switch, described solar array is also connected with electricity accumulating unit, described electricity accumulating unit comprises the charge-discharge control circuit be connected successively, storage battery, described charge-discharge control circuit is connected with solar array, the output of described storage battery is connected to the input of inverter, described support comprises the bracing frame at top and the angle regulator for adjusting support frame angle.Diverter switch determines the supply object of the electric energy of roof photovoltaic module, and the electric energy of solar array divides two-way to export, a road through DC-DC converter, filter circuit to inverter, another road through charge-discharge control circuit, storage battery to inverter.Utilize storage battery electric power storage to provide stand-by power supply, solar array can be avoided to generate electricity not enough situation.Utilize the angle of angle regulator to solar array to regulate, make solar array be in best irradiating angle, to improve generating efficiency.
As preferably, support frame as described above comprises square supporting frame, and described supporting frame is made up of L-type steel.The sheet of solar array squarely, L-type ladle draws together vertical steel plate and the horizontal steel plate vertical with vertical steel plate, and horizontal steel plate is all arranged on the inner side of vertical steel plate, to its supporting role of solar array; Vertical steel plate is positioned at the surrounding of solar array, from surrounding to position restriction effect solar panels; Utilize square supporting frame to be fixed solar array, its structure is simple, with low cost, and is convenient to make.
Further, the diagonal of described supporting frame is connected with reinforcement.Because solar array slabbing is square, only support from its surrounding, its structural instability, especially center.The diagonal of supporting frame arranges reinforcement, and it can not only strengthen the stability of supporting frame structure, also plays a supportive role to solar array, strengthens the stability of solar array structure, especially its center.
Further, described angle regulator comprises angle demodulator with Duo Gen for being connected the support bar of supporting frame and angle demodulator.
Further, described angle demodulator is motor.Utilize the rotation of motor to drive support bar to rotate and reach the object controlling solar array and rotate, it is convenient to control.
As preferably, described DC-DC converter is Boost boost chopper.
To sum up, the beneficial effects of the utility model are:
1, the electric energy of solar array of the present utility model divides two-way to export, one tunnel through DC-DC converter, filter circuit to inverter, another road through charge-discharge control circuit, storage battery to inverter, diverter switch determines the supply object of the electric energy of roof photovoltaic module, can realize the grid-connected use of family expenses photovoltaic generating system and national grid.
2, the angle of angle regulator of the present utility model to solar array regulates, and makes solar array be in best irradiating angle, generating efficiency is improved.
