在当前追求清洁能源、推动可持续发展的大背景下，租赁屋顶安装光伏逐渐走进大众视野，成为不少业主和企业关注的投资选择。但这项业务是否靠谱，需从多个维度深入剖析。

In the current context of pursuing clean energy and promoting sustainable development, renting roofs to install photovoltaics has gradually entered the public eye and become an investment choice of concern for many homeowners and enterprises. But whether this business is reliable or not requires in-depth analysis from multiple dimensions.

收益回报层面

On the level of return on investment

从收益角度来看，租赁屋顶安装光伏存在可观的获利空间。对于屋顶业主而言，将闲置屋顶出租，每年可获得一笔稳定的租金收入。租金价格通常根据屋顶面积、所在地区光照条件等因素确定，一般每平方米每年租金在 20 - 50 元不等。例如，在光照资源丰富的地区，若有一处 1000 平方米的屋顶，每年仅租金收入就可达 2 - 5 万元。同时，若屋顶业主自身用电量大，还可享受光伏发电的优惠电价，进一步降低用电成本。

From a revenue perspective, there is considerable profit potential in leasing roofs to install photovoltaics. For rooftop owners, renting out idle roofs can provide a stable annual rental income. The rental price is usually determined based on factors such as roof area and lighting conditions in the area, with an annual rent ranging from 20-50 yuan per square meter. For example, in areas with abundant lighting resources, if there is a 1000 square meter roof, the annual rental income alone can reach 20000 to 50000 yuan. At the same time, if the rooftop owner consumes a large amount of electricity themselves, they can also enjoy preferential electricity prices for photovoltaic power generation, further reducing electricity costs.

对于投资安装光伏系统的企业，通过将光伏发电上网卖给电网公司，可获取售电收益。以一个装机容量为 100 千瓦的光伏电站为例，假设当地光照充足，年发电小时数可达 1200 小时以上，每度电上网电价按 0.8 元计算（含补贴），每年发电收益可达 9.6 万元左右。扣除设备投资、运维成本等，在电站长达 25 年左右的使用寿命周期内，有望获得较为丰厚的利润回报。

For enterprises investing in the installation of photovoltaic systems, selling photovoltaic power generation to grid companies can generate electricity sales revenue. Taking a photovoltaic power station with an installed capacity of 100 kilowatts as an example, assuming sufficient local sunlight and an annual power generation hours of over 1200 hours, the on grid electricity price per kilowatt hour is calculated at 0.8 yuan (including subsidies), and the annual power generation revenue can reach about 96000 yuan. Deducting equipment investment, operation and maintenance costs, etc., the power station is expected to obtain relatively substantial profit returns during its service life of about 25 years.

合作模式解析

Analysis of Cooperation Mode

在合作模式上，常见的有合同能源管理（EMC）和屋顶租赁两种。合同能源管理模式下，光伏投资企业负责电站的投资、建设、运营和维护，屋顶业主无需投入资金，只需提供屋顶。双方按约定比例分享发电收益，这种模式能让屋顶业主零成本享受光伏带来的节能效益和额外收入。屋顶租赁模式则较为简单直接，业主将屋顶出租给光伏企业，定期收取租金，电站的运营收益全部归光伏企业所有。这两种模式各有优劣，业主可根据自身需求和实际情况选择。

In terms of cooperation modes, there are two common ones: energy performance contracting (EMC) and rooftop leasing. Under the contract energy management mode, photovoltaic investment enterprises are responsible for the investment, construction, operation, and maintenance of the power station. Rooftop owners do not need to invest funds, only need to provide the roof. Both parties share the power generation revenue according to the agreed proportion, which allows rooftop owners to enjoy the energy-saving benefits and additional income brought by photovoltaics at zero cost. The roof rental model is relatively simple and direct, where the owner rents out the roof to a photovoltaic company and collects rent regularly. The operating income of the power station belongs entirely to the photovoltaic company. These two modes have their own advantages and disadvantages, and homeowners can choose according to their own needs and actual situation.

风险因素考量

Risk factor considerations

然而，租赁屋顶安装光伏也并非毫无风险。一方面，光伏电站的发电效率受天气、光照等自然因素影响较大。若遇到连续阴雨天气或当地空气质量不佳导致光照强度减弱，发电量会明显下降，进而影响收益。另一方面，光伏设备存在一定的故障率，虽然随着技术进步，设备可靠性不断提高，但仍可能出现逆变器故障、组件损坏等问题，维修成本和停机时间会对投资回报产生不利影响。此外，政策风险也不容忽视，国家对光伏发电的补贴政策可能会调整，上网电价也可能波动，这都可能影响项目的整体收益。

However, renting roofs to install photovoltaics is not without risks. On the one hand, the power generation efficiency of photovoltaic power plants is greatly affected by natural factors such as weather and lighting. If there is continuous rainy weather or poor local air quality leading to a decrease in light intensity, the power generation will significantly decrease, thereby affecting revenue. On the other hand, photovoltaic equipment has a certain failure rate. Although the reliability of equipment continues to improve with technological progress, problems such as inverter failures and component damage may still occur. Maintenance costs and downtime will have a negative impact on investment returns. In addition, policy risks cannot be ignored. The subsidy policy for photovoltaic power generation by the government may be adjusted, and the on grid electricity price may also fluctuate, which may affect the overall revenue of the project.
