近年来，分布式光伏电站发展越来越好，全国各地都在陆续普及，但对于很多想了解光伏电站经常会问我很多问题，今天小编给大家整理了一些常见问题，供大家参考：

1、装一套太阳光伏系统大概需用花多少钱?

       答：一般来说，家中安裝屋顶光伏发电系统都在5千瓦至10千瓦的容量，按照现阶段光伏发电系统1w大约在3.8元-4元左右，加入安装一套10千瓦的光伏电站，大概需要3.8-4万左右。

2、自己家想安装光伏发电系统需要做那些准备？

       答：需要采集一些基本资料，包括太阳光照资源、建筑类型(民房or商品楼)、屋面结构、房顶占地面、月用电量等。依据上述信息内容，我们会为你设计一套最经济适用的系统方案，以达到利益最大化。

3、商品楼能够安裝屋顶光伏发电系统吗?

       答：商品楼是可以安裝的，但需向单元楼住户居民和物业公司详细说明情况，申请表需用住户居民签字和物业公司盖章，成为并网申请办理的资料存档。这种情况比较复杂，涉及屋顶产权问题，如果物业户主都同意那就没有问题。

4、太阳能发电对电压有影响吗，是否会影响家电的使用?

       答：分布式光伏发电系统因功率较小，对电压的影响根本感觉不到。再者，逆变器的功能是将光伏电池发的直流低压电转换为220V/380V民用电，而光伏专用逆变器本身就具有智能调节电压的功能，因此光伏电使用起来同电网电没有区别，不会影响家用电器的使用。

5、使用了太阳能发电，当电网停电时我们还会有电吗?

       答：没有。当电网停电，并网发电系统停止工作(如电网维护光伏继续工作会造成电网事故)。假若需用在此情况下自发自用，您能够 选择额外加装一个蓄电池等装置。现阶段蓄电池价格较高且寿命较短（5年），一般来说不建议安裝。

6、工厂房顶并不是我的，请问一下我能安裝光伏电站吗?

       答：可以安装，但需通过和房主协商租用房顶来获得房顶的使用权，之后再建发电站，这样做的话，你就是合法的发电站拥有人了。假若有必要，发电站也可以搬家的。

7、一个光伏电站多少年可以回本？

       答：从长久看来，太阳能发电的收益是很客观的。现阶段国家和政府部门都在积极支持太阳能发电，有非常好的补贴政策优惠，一般来说家用的在5-6年会完全收回成本费。而太阳能组件使用寿命的情况为25年，成本费收回后就是收益。

8、光伏发电系统的稳定性怎样，是否会过几年就不行了?

       答：建议选择大品牌的组件，一般来说都他们都通过全球各地的权威检测认证，通过了抗盐雾和氨腐蚀测试，且具有优秀的弱光环境光伏性能。组件使用25年后的光伏性能还能保持80%以上。

9、屋顶光伏发电系统安装对周围环境有什么要求?

       答：光伏发电系统周围有大的粉尘污染源，风沙较大，浓烟多等影响太阳光照的使用环境也将导致发电能力下降。需要清洁

10、冬季天气冷时，是否会电力不足?如何解决?

       答：家用光伏发电的发电能力的确受到气温影响，但影响特别小，直接影响发电能力的关键因素是辐照强度和日照时长及其太阳电池组件的环境温度。冬季的时候，气温比较低，日照时长会短，因此一般来说发电能力较夏天会少，这也是正常现象。

11、光伏发电系统的发电能力和并网的上网电量能够监控吗?

       答：一般来说家用光伏发电中的逆变器具有监控功能，能够 对系统的发电能力达到在线监测，另外监测系统还可对关键设备参数、电能质量、环境参数等达到在线监测。并网的上网电量主要是通过在并网点安裝经过当地电力部门认可的电能计量表来进行监控。

12、什么是“自发自用，余电上网”?

       答：自发自用，余电上网是指光伏发电系统所发电力一部分由用户自个使用，多余电量接入电网卖给电网公司。结算依据按照并网时安裝在用户侧的双向计量表进行计量。

In recent years, the development of distributed photovoltaic power plants has been getting better and better, and they have been gradually popularized throughout the country. However, for many people who want to understand photovoltaic power plants, they often ask me many questions. Today, the editor has compiled some common questions for everyone's reference:
1. How much does it cost to install a solar photovoltaic system?
Answer: Generally speaking, installing a rooftop photovoltaic power generation system at home has a capacity of 5 to 10 kilowatts. According to the current photovoltaic power generation system, the cost of 1 kilowatt is about 3.8-4 yuan. Adding a 10 kilowatt photovoltaic power station to the installation would require approximately 38000 to 40000 yuan.
2. What preparations do I need to make to install a photovoltaic power generation system in my home?
Answer: It is necessary to collect some basic information, including solar radiation resources, building type (residential or commercial buildings), roof structure, roof area, monthly electricity consumption, etc. Based on the above information, we will design the most economical and applicable system solution for you to achieve maximum benefits.
3. Can a rooftop photovoltaic power generation system be installed in a commercial building?
Answer: Commercial buildings can be installed, but detailed information needs to be provided to the residents of the unit building and the property management company. The application form needs to be signed by the residents and stamped by the property management company, which will be archived as the information for grid connection application processing. This situation is quite complex and involves the issue of roof property rights. If all property owners agree, then there is no problem.
4. Does solar power generation have an impact on voltage and will it affect the use of household appliances?
Answer: Distributed photovoltaic power generation systems, due to their low power, have no noticeable impact on voltage. Furthermore, the function of the inverter is to convert the DC low voltage generated by the photovoltaic battery into 220V/380V household electricity. The photovoltaic dedicated inverter itself has the function of intelligent voltage regulation, so the use of photovoltaic electricity is no different from that of grid electricity and will not affect the use of household appliances.
5. When solar power is used for power generation, will we still have electricity when the power grid goes out?
Answer: No. When the power grid is cut off, the grid connected power generation system stops working (such as maintaining the grid and continuing to operate the photovoltaic system, which can cause grid accidents). If you need to use it spontaneously in this situation, you can choose to install an additional device such as a battery. At present, the price of batteries is relatively high and their lifespan is relatively short (5 years), so it is generally not recommended to install them.
6. The factory roof is not mine. Can I install a photovoltaic power plant?
Answer: It can be installed, but you need to negotiate with the homeowner to rent the roof to obtain the right to use it, and then build a power station. By doing so, you are the legal owner of the power station. If necessary, the power station can also be moved.
