For the "residential user distributed photovoltaic power generation project" formally connected to the grid, many citizens are curious about how much electricity can be generated per day by roof power generation and how to detect how much electricity is uploaded per day?
1. How much electricity can you generate in a day?
At present, it can produce more than 30 degrees.
In Zhu Qijie's home, the reporter saw that the roof photovoltaic power generation equipment of his home was divided into two parts. The main part was on the roof of the second floor building, consisting of 22 solar photovoltaic panels with 250W power, about 45 square meters. There is also a 250W solar photovoltaic panel to implement the "self-service" off-grid design, through off-grid inverters will be stored in batteries, dedicated to the room television.
"The power of the whole set of equipment in the second floor building is 50 million yuan, which has been integrated into the national power grid. The cost of the whole set is about 50,000 yuan. At present, it can generate three degrees of electricity in an hour." Zhu Qijie introduced that more than 30 kilowatt-hour electricity can be generated every day. At present, it uses "self-service, surplus power to connect to the Internet", only two or three kilowatt-hour electricity is consumed every day, and the rest of the electricity is uploaded to the State Grid.
2. How to detect electricity consumption?
Computer Installation Software Monitoring
"Look at today's power generation" now shows 8.9 kWh and real-time effective power at 3.4 kWh. Pointing to the computer screen, Zhu Qijie told reporters that the real-time effective power is the current power generation, equivalent to an hour is 3.4 degrees.
"In addition to monitoring power generation, you can also see the energy-saving and emission reduction data of photovoltaic power generation." Zhu Qijie introduced that he installed a professional system for monitoring roof power generation, which monitors information data such as power generation per hour, power generation per day, voltage, current and frequency.
Zhu Qijie introduced that the equipment can also monitor the safety performance of the equipment. For example, the inverter which converts photovoltaic DC to AC is very important in the whole equipment. If the temperature is too high, it is easy to cause damage. "Therefore, the monitoring software set the best temperature is 60 degrees Celsius, once exceeding this temperature, will automatically"trip"to stop transmission to the grid. He pointed to the screen and said it was not only for the sake of the safety of his own circuit, but also for the sake of protecting the State Grid and the residents.
Are these devices monitored accurately? Power supply department officials said that professional bidirectional meters for measuring transmission capacity have been installed, and the amount of power uploaded should be based on the meter.
