Photovoltaic power generation system is the use of photovoltaic effect to convert solar energy into electricity system, its categories can be divided according to different classification standards. The following is an introduction to the main categories of photovoltaic power generation systems: Solar system panel , solar inverter,Solar lifepo4 battery,Solar lead acid battery, solar controller Foshan Keylewatt Technology Co., LTD , https://www.klwenergy.com
First, according to the access to the power grid classification
Grid-connected photovoltaic power generation system
Definition: Connected to the public grid, the generated electrical energy is input to the grid.
Composition: mainly includes photovoltaic array, grid-connected inverter, load and power grid. Grid-connected photovoltaic power generation systems usually do not need to configure batteries, relying on the grid for energy storage regulation.
Application scenario: Suitable for photovoltaic power generation projects of various scales, including large ground power stations, medium-sized industrial and commercial power stations and small household power stations.
Advantages: It can make full use of the power of photovoltaic array, reduce energy loss and reduce system cost. At the same time, the excess energy can be sold to the power company at a profit.
Off-grid photovoltaic power generation system
Definition: photovoltaic power generation system that is not connected to the public grid and operates independently.
Composition: Mainly includes solar modules, controllers, batteries and inverters (if AC is required).
Application scenario: It is usually built in remote areas far from the power grid or used as a mobile portable power supply in the field, such as remote mountains, no power areas, islands, communication base stations and street lights.
Advantages: not subject to regional restrictions, not dependent on the power grid, wide range of use. It can be installed and used wherever there is sunlight.
Second, classified by energy storage device
Photovoltaic power generation system with energy storage device
Features: The system contains energy storage devices such as batteries, which are used to store excess electric energy to ensure that it can still supply power when there is no light or power grid outage.
Application scenario: Applicable to situations where continuous power supply is required, such as communication base stations, hospitals, and data centers.
Photovoltaic power generation system without energy storage device
Features: The system does not contain storage devices such as batteries, and all the generated electricity is directly input into the grid or supplied to the load.
Application scenario: Applicable to areas where the power grid is stable and the light is sufficient, and where users do not have high requirements on the continuity of power supply.
3. Classification by system structure
Centralized grid-connected photovoltaic power generation system
Features: Mainly use desert and other concentrated areas to build large-scale photovoltaic power stations, power generation directly into the public grid, access to high-voltage transmission system.
Application scenario: Suitable for large-scale photovoltaic power generation projects, such as national power stations.
Distributed grid-connected photovoltaic power generation system
Features: Generally built in the vicinity of users, such as industrial plants, public buildings, residential roofs and so on. The electricity produced is mainly for the user's own use.
Application scenario: Suitable for distributed photovoltaic power generation projects of various scales, with the characteristics of small capacity and low voltage level.
When is Landwind Happy? It has been unveiled at the Guangzhou Auto Show before, and it looks quite attractive when it comes to appearance.
In recent years, the growth of China's self-branded automobile industry has been remarkable. When it comes to design and build quality, many domestically produced vehicles now rival their international counterparts, all while maintaining a competitive price point that’s appealing to local consumers. This progress is undoubtedly a positive development for the automotive market in China.
One notable vehicle that has caught attention recently is the Landwind Happy. This SUV made its debut at the Guangzhou Auto Show and quickly became a topic of discussion among car enthusiasts. Its sleek exterior design is particularly eye-catching, with a youthful and modern aesthetic that appeals to a broad audience.
The front end of the Happy is particularly striking, featuring a bold grille design that incorporates a "flying wing" motif. A thick chrome trim stretches across the top of the headlamps, creating a seamless connection between the two sides. Inside these lamps lies a set of LED daytime running lights, which enhance the vehicle's overall presence. The Happy’s styling is clearly aimed at younger buyers who appreciate contemporary design elements.
Turning our focus to the rear, the design emphasizes both layers and lines, with careful attention paid to the integration of the taillights and surrounding panels. The absence of unnecessary embellishments ensures a clean and timeless appearance. Notably, the taillights themselves are constructed using LED technology, and a distinctive C-shaped reflector echoes the styling cues from the front, though it serves more as a stylistic detail than a functional lighting element.
Stepping inside, the cabin of the Landwind Happy exudes simplicity yet sophistication. High-quality leather seats provide comfort, while the three-spoke steering wheel is equipped with intuitive multifunction controls. A unique feature is the sporty non-circular gear shifter positioned on the central console. Additionally, an 8-inch floating LCD touchscreen adds a touch of modernity and technological flair to the interior.
Under the hood, the Happy is rumored to be powered by a 1.5-liter turbocharged engine capable of delivering up to 120 kW of maximum power. As for the transmission system, a 6-speed manual or continuously variable transmission (CVT) is anticipated to be paired with this engine, offering drivers a balance of performance and efficiency.
With its attractive design, impressive features, and competitive pricing, the Landwind Happy stands out as a promising option in the growing lineup of domestically produced SUVs. Are you excited about what this vehicle could mean for the future of affordable, high-quality Chinese automobiles?
