The combination of new technology and renewable energy is giving birth to the infrastructure of a new industrial revolution - the energy Internet of things. If the last industrial revolution was based on fossil fuels such as oil and coal, the new industrial revolution will be dominated by new renewable energy sources. Compared with geothermal energy, ocean energy, and wind energy, which are limited by time, space and other factors, solar energy has obvious advantages in future energy substitution, and the market share will also be larger. Therefore, future investment in the photovoltaic industry chain is also very promising.
In addition to having an idle roof to install a home photovoltaic system, the property rights of the roof must be clear and the roof is in good condition. It is not possible to install photovoltaic power generation casually. Before installation, it is strictly reviewed and approved, and home photovoltaic power system generation can be installed. There are two grid-connected modes for household solar power plants. One is self-generated and self-consumed surplus electricity, that is, a part of the electricity generated by photovoltaics is used by itself, and the unused electricity is sold to the grid. The second type is full access to the Internet, that is, all the electricity generated by the home photovoltaic system is sold to the grid, and it is not used by itself. In this case, the grid purchases all the electricity generated by the power station or solar energy devices at the local photovoltaic power generation benchmark on-grid price.
Advantages of home photovoltaic system power generation: 1. No greenhouse gases, other waste gas and waste water are emitted during photovoltaic power generation. Photovoltaic power is truly environmentally friendly green power. 2. The operation and power generation of the home photovoltaic system does not require fuel and water sources. 3. The home photovoltaic system is easy to construct, operate and maintain. 4. The grid connected photovoltaic system has stable, reliable performance and long service life. 5. Photovoltaic power generation brings positive energy to the improvement of local microclimate environment.
From the perspective of application, why is the home photovoltaic system so optimistic? A very important reason is the cost of solar power generation. By using LCOE (Levelized Cost of Electricity) to measure the unit power generation cost of the entire photovoltaic power station life cycle, it can be used to compare with other power generation costs. According to the China Photovoltaic Industry Association, industry Distributed photovoltaic power generation has achieved electricity-side parity, and the realization of residential electricity-side parity will also be just around the corner. To sum up, the photovoltaic industry has advantages from the source of solar energy to electricity consumption, and occupies a very important position in future energy consumption.
