Earlier, we talked about the installed capacity of about 1 kilowatt of electricity per 1 watt a year, and introduced the method of quickly estimating the proposed installed capacity, if at this time, you estimate that a factory can install 1MW, then obviously, you can calculate that 1 megawatt photovoltaic power station can generate about 1 million kilowatts of electricity a year, of course, the northwest Shandong and other places with particularly good sunlight can generate 1.3 million kilowatts, and the Sichuan and Chongqing regions with the worst sunlight may only be 800,000 kilowatts. Let's assume that 1 megawatt of electricity is 1 million kilowatts a year, then we directly divide the annual electricity consumption of the plant by the estimated annual power generation of the photovoltaic power station to get a ratio, if this ratio is less than 1, the consumption rate is less than 50%;The ratio is about 1, and the absorption rate is about 50% to 60%, which belongs to the general consumption projectThe ratio is about 2, and the absorption rate is about 70%, which is barely acceptableThe ratio is about 3, and the absorption rate is about 80%, which is considered a high consumption projectThe ratio is about 4, and the absorption rate is about 90% or more. The above estimation method is suitable for the vast majority of factories, most of their operating time is during the day, and the output of 12 months a year is relatively average, if a factory is special, mainly started at night, or seasonal production in 1 year, the shutdown period is relatively long, then the consumption rate estimated by this ratio needs to be discounted.
