The previous article introduced the two types of AC solar power generation systems - AC inverter and AC-DC inverter. Now, let's explore another type called the mains complementary photovoltaic power generation system. This system operates on similar principles but with a different configuration. To maintain the original information, I will rearrange the content accordingly.
A complementary photovoltaic power generation system is designed to work alongside an existing power source in order to increase overall energy efficiency and reduce dependency on traditional energy sources. This system typically consists of photovoltaic panels that are installed alongside the main power generation system, allowing them to harness the power of the sun to produce electricity. This supplemental power source can be particularly useful during periods of high demand or when the main power source experiences outages or other interruptions. By utilizing both the traditional power source and the complementary photovoltaic power system, businesses and homeowners can reduce their overall energy costs and improve their environmental impact.
The main complementary system for generating photovoltaic power relies heavily on solar photovoltaic technology, with additional power from regular 220V AC. By utilizing this approach to generate power, the solar cell and storage battery capacities are designed to be smaller. Essentially, when there is daylight, the autonomy of the system kicks in, but in cases of extended rain or gloomy weather, power is supplemented by the mains. According to statistics, most regions in China tend to be sunny over two-thirds of the year. This methodology not only reduces the initial cost of installing solar photovoltaic power systems but also has a remarkable impact on energy conservation and emission reduction, making it a great way of promoting and popularizing solar power generation.
The mains complementary photovoltaic power generation system is being utilized in various applications, such as the renovation of street lamps in urban areas. The significant investment cost of replacing ordinary street lamps with solar street lamps makes it an impractical solution. To tackle this challenge, the concept of mains complementary photovoltaic power generation is being used. By modifying the ordinary street lamps and substituting them with energy-saving light source lamps and lanterns, coupled with photovoltaic power generation as a secondary power supply, mains complementary solar photovoltaic street lights are formed, all while retaining the original mains power supply lines and lamp poles. This approach cuts down investment costs by more than half, and the energy-saving effect is significant. Therefore, the mains complementary photovoltaic power generation system is a cost-effective and efficient solution for urban street light renovations.
