一千瓦光伏发电需要投资多少钱? 多久回本?寿命多长

返回列表 来源: 电力资源库 发布日期: 2021.12.03 浏览次数:

    一瓦大概8元左右,一千瓦就是8千元投入了,光伏发电的寿命是25年左右,如果是家用的话,比如电费6毛每度,回本大概8年。这些都是理论计算了,实际上考虑到设备老化维修费用,当地日照时间和强度等问题,还有设备本身效率问题,会大打折扣的。你如果搞1千瓦,那就不叫投资了,叫玩时髦,也就是够家里几个灯泡照明使用了,真正要投资,你要考虑10KW以上了微信图片_20211111141309

1、投入大,必须形成规模才能见效益,否则人家电网不屑地要你并网,国家对电能质量要求较高。如果不能达到国家要求,也就不能入网,也就不能拿到国家补贴。发的电不能并网,就得不偿失了。

2、由于价格竞争,很多设备厂家会偷工减料,很多参数会虚标,弄不好还会几年就坏了,你自己又不懂技术,找人维修要花很多钱,半途只 能放弃,白白花钱了。

3、要注意政策风险,现在国家开始不支持小规模了,最好别投了,据说三年一个政策 , 三年年以后谁也说不准,万一到时不补贴了,你投入只能两眼泪汪汪。

A watt is about 8 yuan, and a kilowatt is 8000 yuan. The service life of photovoltaic power generation is about 25 years. If it is for household use, for example, the electricity charge is 60 cents per kWh, which is about 8 years. These are theoretical calculations. In fact, considering the aging and maintenance costs of the equipment, the local sunshine time and intensity, as well as the efficiency of the equipment itself, it will be greatly reduced. If you are engaged in 1 kW, it is not called investment, it is called playing fashion, that is, it is enough to use several light bulbs at home. If you really want to invest, you should consider more than 10kW

1. If the investment is large, it must form a scale to see benefits, otherwise people's power grid disdains to ask you to connect to the grid, and the state has high requirements for power quality. If you can't meet the national requirements, you can't access the network and get state subsidies. If the electricity generated cannot be connected to the grid, the gain is not worth the loss. picture

2. Due to price competition, many equipment manufacturers will cut corners, and many parameters will be falsely marked. If they don't do it well, they will break down in a few years. You don't know the technology. It will cost a lot of money to find someone to repair. You can only give up halfway and spend money in vain. Picture picture

3. We should pay attention to policy risks. Now that the state does not support small-scale investment, it is best not to invest. It is said that one policy will be implemented every three years. After three years, no one is sure. If there is no subsidy at that time, you can only invest in two tears
