Introduction of Distributed Solar Photovoltaic Power Generation System

1. How to make a household distributed solar photovoltaic power generation system?


First of all, it is necessary to understand your basic information, including (house title certificate), the type and structure of the house, the area of the roof, the monthly electricity consumption, the light intensity, etc.


Based on the above information, we will design a set of the most cost-effective household distributed solar photovoltaic power generation system solutions for you to maximize benefits.

 

2. What is a household distributed solar photovoltaic power generation system?


Distributed solar photovoltaic power generation system refers to a user-side grid-connected power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy.


This system is located near the user, and the generated electric energy is used locally, connected to the power grid at a voltage level of 10 kV and below, the total installed capacity of a single grid connection point (380V) does not exceed 6 MW, and the total installed capacity of a single grid connection point on the 220V user side not exceeding 8 kW.


3. How much does it cost to install a home distributed solar photovoltaic power generation system?


The average household installed rooftop photovoltaic power generation system has a capacity of more than 3 kilowatts. According to the current industry photovoltaic power generation system cost ranging from about 4000 yuan/kW to 4800 yuan/kW (depending on the difficulty of the installation environment and construction), install a set of photovoltaic power generation system. The power generation system needs at least more than 10,000 yuan (the cost of installed capacity increases with different installation areas).


4. Application scope and installation method of distributed solar photovoltaic power generation system?


The distributed solar photovoltaic power generation system can be installed in any place with sunlight, including: the ground, the top of the building, the side/facade, the balcony, etc., in schools, hospitals, shopping malls, villas, residential buildings, factories, enterprises and institutions roofs, carports, and the top of bus stop signs are the most widely used, and commercial housing can also be installed.


However, it is necessary to explain the situation to the residents of the unit building and the property. The application form for the installation of the distributed solar photovoltaic power generation system needs to be signed by the residents and stamped by the property, and archived as the data for the grid connection application.


It can be installed on the basis of concrete, color steel plate and tile type, etc., and can also replace its substrate, especially the application of glass substrate.


5. How to estimate the installed capacity and power generation of distributed solar photovoltaic power generation system?


According to the actual available area provided by you, 100-180 watts (components) of photovoltaic glass panels can be installed per square meter (depending on the transmittance, the higher the transmittance, the lower the capacity), the installation of photovoltaic power generation system The higher the annual average sunshine hours at the location, the higher the power generation. 


6. Will the household distributed solar photovoltaic power generation system affect the roof?


The existing designs are all overhead, which will not cause any damage to the roof or cause water accumulation, and has the advantages of heat insulation, shading in summer, warmth in winter, and protection of building foundations.


7. How safe is the household distributed solar photovoltaic power generation system?


First of all, DC combiner boxes, inverters and other equipment lines have overload protection functions. When abnormal voltages such as lightning strikes and leakage occur, they will be automatically turned off and disconnected, so there is no safety problem.


Secondly, the surface of our photovoltaic power generation system components is made of super impact-resistant tempered glass, which has undergone rigorous testing and testing when passing the EU certification, and can withstand wind pressure of 2400Pa and snow pressure of 5400Pa.


In addition, each PV module can operate independently, even if one module is damaged, it will not affect the normal operation of other modules.


8. How long is the lifespan of a household distributed solar photovoltaic power generation system and will it be troublesome to maintain?


The general life of photovoltaic modules is about 25 years, and the maintenance is relatively simple. Generally, it is to remove the shielding objects such as bird droppings and leaves on the photovoltaic glass panel.


In addition, photovoltaic modules are modular and closed, and generally do not require maintenance. During the warranty period, the photovoltaic power generation system is not artificially damaged, and the manufacturer is responsible for free replacement.
