Home Rooftop Photovoltaic Power Generation System Solution

Countries around the world have vigorously supported the photovoltaic power generation industry and frequently introduced preferential policies to encourage people to build and invest in photovoltaic power generation projects and use idle roofs of factories and families to build distributed photovoltaic power stations. Among them, household rooftop photovoltaic power generation stations have low investment and high returns, and have attracted people's attention. Household photovoltaic power stations are entering our lives at a rapid pace.

Definition of household photovoltaic power station:

Household solar photovoltaic power generation systems are divided into off-grid power generation systems and grid-connected power generation systems:

1.Off-grid rooftop power generation system. It is mainly composed of solar cell modules, controllers, batteries, and AC inverters. If you want to power AC loads, you also need to configure an AC inverter household solar power generation system.

The grid-connected rooftop power generation system is that the DC power generated by the solar module is converted into AC power that meets the requirements of the municipal power grid by the grid-connected inverter and then directly connected to the public power grid. The grid-connected power generation system has centralized large-scale grid-connected power stations, which are generally national-level power stations. The main feature is that the generated energy is directly transmitted to the power grid, and the power grid is uniformly allocated to supply power to users. However, this type of power station has large investment, long construction period, large land area, and is difficult to develop and promote. The decentralized small-scale grid-connected power generation system, especially the rooftop photovoltaic power generation system, uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use. Due to its advantages of small investment, fast construction, small footprint, and strong policy support, it is the mainstream of grid-connected power generation.
