Photovoltaic controller is an automatic control device used in photovoltaic power generation systems to control multiple photovoltaic cell arrays to charge batteries and batteries to supply power to photovoltaic inverter loads. The main functions of the photovoltaic controller are high-voltage (HVD) disconnection and recovery functions, under-voltage (LVG) alarm and recovery functions, and low-voltage (LVD) disconnection and recovery functions to prevent excessive battery discharge, and can protect system circuits and lightning protection Breakdown.  The photovoltaic controller uses a high-speed CPU microprocessor and a high-precision A/D analog-to-digital converter. It is a microcomputer data acquisition and monitoring control system. It can quickly collect the current working status of the photovoltaic system in real time and obtain the working information of the photovoltaic power station at any time. It can also accumulate historical data of the photovoltaic power station in detail, providing a basis for evaluating the rationality of the design of the photovoltaic power generation system and inspecting the reliability of the quality of system components. Accurate and sufficient basis.  Photovoltaic controllers can be classified into single-channel controllers, multi-channel controllers, pulse-width modulation types, intelligent controllers, etc.

Germany’s balcony PV installations hit 200 MW in H1 Germany’s Federal Network Agency (Bundesnetzagentur) says 220,000 balcony PV systems were installed in the country in the first half of the year, reaching 200 MW. JULY 19, 2024 SANDRA ENKHARDT MARKETS MODULES & UPSTREAM MANUFACTURING RESIDENTIAL PV GERMANY Image: EET Energy From pv magazine Germany Germany deployed 200 MW of balcony PV systems in the first half of this year, according to new figures from Bundesnetzagentur. The agency reported that the capacity is represented by approximately 220,000 new systems. It attributed the recent growth to the simplified registration of plug-in solar devices, which have been available since April. The average registered gross output of these systems has increased from 800 W last year to around 900 W this year, it said. It remains unclear whether all new PV balcony systems have been recorded in the market master data register. Bundesnetzagentur said the actual installed capacity total could be higher, as many PV system owners may still need to register their installations. Germany added 9.3 GW of renewables in the first half of the year, with around 7.55 GW coming from photovoltaics. These figures are likely to increase in the coming months, said the agency. “We are seeing a continuous expansion, particularly in PV,” said Bundesnetzagentur President Klaus Müller. “Compared to the total output at the end of 2023, almost 10% more solar power was added.” Germany has installed more than 90 GW of solar capacity, and the nation is expected to reach 215 GW by 2030. Müller described this as “an enormous development and a challenge for the entire transformation process in the electricity sector.” This content is protected by copyright and may not be reused.

Vietnam’s rooftop photovoltaic policy is turning around Deputy Prime Minister Tran Hong Ha has instructed the Ministry of Industry and Trade to study the option of buying rooftop solar energy and report by Thursday. But the government does not want to buy more than 10% of each system’s capacity, he said.This is an unexpected reversal within a month’s time: a draft of a proposed decree the ministry issued last month said it "will not buy rooftop solar power in any form" except from projects approved under National Power Development Plan 8.It had said that since rooftop solar generation is unstable and the units are costly to operate they are only encouraged for household use.But analysts had said in reply that the government should buy a portion of rooftop power though with a purchase limit to stop sellers from taking advantage of the national grid.There are around 103,000 rooftop solar systems in Vietnam with a total capacity of 9,500 megawatts.By 2030 the government wants them installed at 50% of workplaces and households.By vnexpress

What is a photovoltaic carport? A photovoltaic carport combines a photovoltaic power generation system with a carport roof. This is an application form that combines photovoltaics with architecture. It can not only realize all the functions of a traditional carport, but also generate electricity and bring benefits to the owners. The photovoltaic parking shed mainly consists of photovoltaic cell module,battery, bracket system, lighting and control inverter system, lightning protection and grounding system, charging device system, etc. Photovoltaic carports can not only provide shade and rain protection for vehicles, but the electricity generated by photovoltaic carports can not only be used by vehicles, but the excess electricity can also be sold to the state, thereby alleviating the city's electricity pressure, and can also bring profits and achieve social and environmental benefits. A win-win situation. The structure of the photovoltaic carport is divided into single-carport photovoltaic carport structure and double-carport photovoltaic carport structure. The support structure can be divided into two types: single-column photovoltaic carport structure and double-column structure. The photovoltaic carport can adopt a photovoltaic integrated structure. The photovoltaic panels are installed on the steel truss above the parking space. The top surface of the carport is replaced with photovoltaic panels. This can not only protect the vehicle from the sun and rain, but also generate electricity to provide lighting for the carport. Charging piles, energy storage and other supporting facilities are installed in the carport, which can charge electric vehicles and electric bicycles, realizing the integration of light, storage and charging.

Energy storage technology refers to the process of storing energy through media or equipment and releasing it when needed; photovoltaic + energy storage combines solar photovoltaic power generation with energy storage technology to store the electric energy generated by the photovoltaic system so that it can be used when needed. Ensure stable power supply when needed. Currently, the system solutions for photovoltaic + energy storage on the market mainly include DC coupling and AC coupling. So what is the difference between these two solutions? The difference between DC coupling and AC coupling DC coupling means that energy storage cells and photovoltaic modules are connected to the DC side of the integrated photovoltaic and storage machine. The integrated photovoltaic and storage machine is directly connected to the photovoltaic modules, and the energy collection point is on the DC side. AC coupling means that the energy storage system and the photovoltaic system are connected on the AC side. , the energy storage system (battery, energy storage inverter) and the photovoltaic system (photovoltaic modules, photovoltaic inverter) work independently of each other, and the energy collection point is on the AC side. However, due to differences in circuit structures and electrical equipment between the two, there are also major differences in working principles, flexibility, efficiency, etc. 1. Differences in working principles DC coupling: In this solution, the photovoltaic inverter and the bidirectional converter are integrated into a photovoltaic and storage integrated machine, and are directly connected to the photovoltaic modules, power grid, battery, etc. to form a whole. When the photovoltaic system is running, the electricity generated can charge the battery through the photovoltaic storage integrated machine, supply power to the load, or be input into the power grid. AC coupling: This solution includes two parts: photovoltaic system and energy storage system. The photovoltaic system consists of photovoltaic arrays and photovoltaic inverters; the energy storage system consists of energy storage inverters and batteries. The two systems can operate independently without interfering with each other, or they can be separated from the power grid to form a micro-grid system. When the photovoltaic system is running, the generated power can be used to power the load through the photovoltaic inverter or be input into the grid, or it can be used to charge the battery through the energy storage inverter. 2. Flexibility Differences DC coupling: In this solution, photovoltaic modules, photovoltaic storage integrated machines and batteries are in a serial state and are closely connected to each other. The addition and removal of equipment is complicated and the flexibility is average. It is mainly used in new photovoltaic markets, such as newly installed Photovoltaic storage systems, photovoltaic modules, integrated photovoltaic storage machines and batteries...

What kind of roof is suitable for installing a photovoltaic power plant? The conditions suitable for installing rooftop photovoltaic power plants are summarized as having abundant solar resources, simple structure, clear property rights, and low environmental pollution. Roof type: Concrete roof: one of the common roof types in residential, unit, and factory buildings. For concrete roofs, the counterweight method is generally used to install photovoltaic panels, that is, concrete counterweight blocks are used as the foundation to stabilize the photovoltaic panels without damaging the original structure of the roof. Color steel tile roof: For color steel tile roof, the clamp method is mainly used to install photovoltaic panels. Tile roofs: Mainly use hooks to install photovoltaic panels. Sunroom: Due to its good lighting performance, the sunroom is also suitable for installing photovoltaic power generation systems. Photovoltaic power stations installed on sloped roofs are more beautiful. Due to the large slope of the roof, rainwater is easy to drain, and the construction is simple and easy to maintain. There is no need to lay brackets, but they are laid according to the current slope angle of the roof during installation. Since there is no need to consider occlusion between components, the components can be completely covered. Flat roofs require bracket installation. On a horizontal roof, photovoltaic arrays can be installed at optimal angles to obtain maximum power generation. The advantage of installing a photovoltaic power station on a flat roof is heat insulation and cooling, which can generally reduce the temperature by 5 to 7 degrees. It adopts the form of cement piers + photovoltaic brackets. The investment cost is not high and the economy is relatively good. Before installing a rooftop photovoltaic power station, you first need to determine whether the house's carrying capacity meets the needs of installing the power station. For houses that have been built for a long time, a comprehensive inspection of the waterproofing of the house and whether the walls are damaged and other overall conditions is required. Household power stations can be installed in buildings with a short construction time, solid brick load-bearing walls with a wall thickness of more than 240mm, and no other problems. Buildings with wall thickness ≤180mm can install power stations according to customized bracket plans. It is best for rooftop photovoltaic power stations to meet the requirements for south-facing installation of photovoltaic modules, and the surrounding trees and other buildings need to be taken into consideration so that the photovoltaic modules will not be blocked and there will be no environmental pollution. If there is a large area of shielding around the roof, the orientation of the roof is unfavorable for the generation of photovoltaic modules, the installation area and usable area of the roof are insufficient, the load-bearing capacity of the roof is...
