First calculate the power generation of the photovoltaic power station, based on the amount of standard coal required for power generation, and then calculate carbon dioxide, nitrogen compounds, etc. based on the amount of coal
For example, a 20MW power station , with a design life of 25 years and an average annual power generation of approximately 17 million kWh.
Compared with coal-fired thermal power stations, calculated based on 320 grams of standard coal/kWh, 5,462 tons of standard coal are saved every year. Then, sulfur dioxide and nitrogen are calculated based on the combustion emissions of one ton of standard coal. compounds (calculated as NO2).
According to the National Development and Reform Commission’s “Announcement on the Announcement of the 2009 Regional Power Grid Baseline Emission Factors for China’s Low-Carbon Technology Fossil Fuel Grid-Connected Power Generation Projects”, the national value of the carbon dioxide emission factor of the national power grid is 0.8665 (tCO2/MWh) , that is, 17 million KWH*0.8665=14730.5 tons of carbon dioxide.
For example, a 20MW power station has a design life of 25 years and generates an average of about 17 million kWh of electricity per year.

Nitride is a binary compound formed of nitrogen and an element with a smaller electronegativity than it. Nitride produced by the direct combination of transition elements and nitrogen is also called metallic nitride. They are "interfill compounds," so-called because nitrogen atoms occupy interstitial positions in the metal lattice.
This compound is metal-like in appearance, hardness and electrical conductivity. It generally has high hardness, high melting point, stable chemical properties and electrical conductivity.
Nitrides such as titanium, vanadium, zirconium, and tantalum are hard and refractory, and are resistant to chemical corrosion and high temperature. For example, TiN has a melting point of 2930-2950°C. It is a good conductor of heat and electricity. It has superconductivity at low temperatures and is a material for manufacturing jet engines. ZrN has superconductivity at low temperatures and is currently used as a reactor material.
