Before installing photovoltaic power generation equipment, a special construction plan for photovoltaic power generation equipment should be formulated, clearly based on the site conditions and characteristics of the photovoltaic power generation equipment. photovoltaic power generation
Targeted technical construction plan, the plan must include targeted measures to avoid damage to photovoltaic modules during transportation and installation.
(1) Bracket installation: The fixed bracket and the manually adjustable bracket are made of steel structure. The tilt of the support meets the design requirements. The manually adjustable bracket can be adjusted.
The movement is flexible and the tracking support is firmly fixed to the foundation.
(2) Installation of photovoltaic modules: photovoltaic modules and various components and equipment are fixed with bolts,and the torque meets the product or design requirements. The open circuit voltage and short circuit current of photovoltaic module strings should be tested for wiring between
after wiring. It is strictly forbidden to touch live metal parts. of the chain during construction.
(3) Installation of the combiner box: The vertical deviation of the installation of the combiner box should be less than 1.5mm.
(4) Installation of the inverter: The top of the base steel section of the inverter should be 10mm higher than the flat floor and have a raised reliable grounding.
Solar water heater installation requirements and steps
Piping requirements: use pipes incompatible with the fluid, such as copper pipes, steel pipes stainless steel and carbon pipes. Pressure Requirements: Generally; It is said that the requirementsPressure pressure systems also have certain standards. Too much pressure will shorten the life of the pipeline, and too little pressure will affect fluid flow and reduce heat absorption capacity.
1. Installing a Solar Water Heater – Installation Requirements
1. Installing solar requires that the house structure has one side sunny and does not block the facade.
2. Determine the installation position so that the horizontal distance between the collector and the water tank is less than 250cm; the lower port of the collector and the water tank is greater than 20 cm. the connection of the two should always keep an upward trend and will not be affected by architectural influences and obstacles.
3. Make sure there is enough space for the sensor to be installed towards the east, south, east, west or west of the building in order to rmeet the duration of continuous solar sunshine of at least 4 hours. .
4. Pay attention to the structure of the balcony. Design the interior pipelines in advance before installation to ensure that the interior is in perfect condition after installation.
2. Solar water heater installation—installation steps
1. Determine the installation location of the solar collector based on the sensor size of the selected system. solar water heater. . (Solar energy is generally installed on the balcony)
2. Determine the installation location of the solar water tank according to the actual situation on the balcony.
3. According to the installation location of the solar water tank, determine the location of the power socket and the outlet reserved for hot and cold water pipes on the balcony.
