Stand-alone solar PV energy system battery array base should use concrete pouring and become, for concrete base height and level deviation need to meet the design requirements specifications, battery array base selection foot bolt for fixed, buried and exposed need to meet the design specification requirements, after the completion of the concrete foot bolt pouring fixed need to maintain at least 5 days to ensure its solidification strength before completion for Stand-alone solar PV energy system rack installation.
In the stand-alone solar PV energy system solar rack installation need to pay attention to
The azimuth and tilt angle of the stand-alone solar PV energy system square frame need to meet the design requirements.
In the installation of stand-alone solar PV energy system rack, pay attention to the need to control the bottom level within the range of 3mm / m, when the level exceeds the allowable range should use the pad iron for leveling.
The surface of the fixed part of the stand-alone solar PV energy system rack should be made as flat as possible to avoid damage to the cells.
The fixed part of the stand-alone solar PV energy system frame should be equipped with anti-loosening gaskets to improve the reliability of its connection.
The angle between the stand-alone solar photovoltaic system frame and the ground can be fixed or adjusted according to the seasonal changes, so that the solar panel can increase the sunlight receiving area and light time as much as possible to improve the power generation efficiency of the stand-alone solar PV energy system.
In the installation of stand-alone solar PV energy system solar modules should pay attention to
When installing solar modules for stand-alone solar PV energy systems, you first need to measure and check each module against its parameters to ensure that they meet the requirements for use, and measure the open-circuit voltage and short-circuit current of the solar modules.
Solar modules with similar operating parameters need to be installed in the same array to improve the power generation efficiency of the independent solar PV energy system array.
During the installation of solar panels and so on, it should avoid knocking to avoid damage to solar panels and so on.
For the solar panels and the fixed frame is not tight with the need to use iron and so on for its pad flat, improve the connection between the two tightness.
In the installation of solar panels need to use the solar panel frame on the prefabricated installation for connection, the use of screws for connection to pay attention to the tightness of the connection, and pay attention to the use of standards in advance to do a good job of relaxation.
The position of the solar module should be as high quality as possible when installed on the rack, while the gap between the solar module and the rack installed on the rack should be greater than 8mm or more to improve the heat dissipation capacity of the solar module.
For solar panels such as junction boxes need to be protected from rain, frost, etc. to avoid damage caused by rain, etc.
In the solar photovoltaic system connection cable layout should pay attention to follow the outdoor first, then indoor, first simple then complex principle to carry out. At the same time in the cable layout also need to pay attention to:
In the wall and the bracket of the sharp edge of the cable should pay attention to do a good job for the protection of the cable.
In the cable laying to pay attention to the direction of the cable and fixed, but also need to pay attention to the cable laying the degree of elasticity to moderate.
In the cable joints to pay attention to do a good job of protection, to prevent oxidation at the joints or off affect the cable connection effect.
The feeder and return lines of the same circuit should be twisted together as much as possible to avoid the impact of electromagnetic interference on the cable.
In the installation of solar PV energy system, attention should be paid to the lightning protection grounding of the solar PV energy system, the grounding cable of the lightning rod should be kept at a certain distance from the support of the solar PV energy system. For solar PV energy system lightning protection can be used to install lightning rod or lightning line two lightning protection methods to protect the safety of solar PV energy system.
