1、產權歸屬問題：根據《城鄉規劃法》規定：未取得建設工程規劃許可證或者未按照建設工程規劃許可證的規定進行建設的建筑、房屋、構筑物，屬于違章建筑，縣級以上城鄉規劃部門，有權要求限期拆除，沒收實物或違法收入，并處罰款。在進行租賃前期，為避免后續的一些麻煩和可能造成的損失，首先應當對房屋的情況進行調查。房屋建設是否合規，是否具有建設規劃許可證、竣工驗收證明、消防驗收證明和房屋產權證明，是否存在抵押、查封等情況。如若情況不明，在租賃時應當謹慎，盡量規避風險和后期不必要的糾紛。

1. Property ownership issue: According to the Urban and Rural Planning Law, buildings, houses, and structures that have not obtained a construction project planning license or have not been constructed in accordance with the provisions of the construction project planning license are considered illegal buildings. Urban and rural planning departments at or above the county level have the right to demand demolition within a specified time limit, confiscate physical objects or illegal income, and impose fines. In the early stage of leasing, in order to avoid any subsequent troubles and potential losses, the condition of the house should be investigated first. Whether the construction of the house complies with regulations, whether there is a construction planning permit, completion acceptance certificate, fire safety acceptance certificate, and property ownership certificate, and whether there is any mortgage or seizure. If the situation is unclear, caution should be exercised during leasing to avoid risks and unnecessary disputes in the future.

2、屋頂使用問題：在租用前，承租方應該對房屋屋頂結構以及防水等問題進行勘察評估，并簽訂書面租賃合同，約定租賃期限、租賃用途、租賃價格和損壞修繕等條款，并向房產管理部門備案，以避免在光伏電站建設和運行過程當中產生不必要的麻煩和糾紛。

2. Roof usage issues: Before renting, the lessee should conduct a survey and evaluation of the roof structure and waterproofing issues of the house, and sign a written lease agreement that specifies the lease term, lease purpose, lease price, and repair of damage. The agreement should also be filed with the property management department to avoid unnecessary troubles and disputes during the construction and operation of the photovoltaic power station.

3、合同能源管理問題：合同能源管理機制，簡稱EMC，是一種以節省的能源費用來支付節能項目全部成本的節能投資方式。簡單點說，就是在光伏電站所發電量的分配和消納問題，如何分配使得能源利用效率大化。出租方的用電量和附近是否有用電大戶，直接關系到光伏電站所發電量的消納以及電量利用效率的大化，同時還需要關注購電方的信用狀況。

3. Contract Energy Management Issues: The Contract Energy Management Mechanism, abbreviated as EMC, is an energy-saving investment method that pays for the full cost of energy-saving projects by saving energy costs. Simply put, it refers to the allocation and consumption of electricity generated by photovoltaic power stations, and how to allocate it to maximize energy utilization efficiency. The electricity consumption of the lessor and whether there are large electricity users nearby are directly related to the consumption of electricity generated by the photovoltaic power station and the maximization of electricity utilization efficiency. At the same time, it is also necessary to pay attention to the credit status of the purchasing party.

另外光伏電站發電所產生的碳排放指標如何分配和利用也關乎著電站的整體收益，所以，如何管理和利用能源，使得利用率大化，也是在屋頂租賃時需要考慮的問題。

In addition, the allocation and utilization of carbon emissions generated by photovoltaic power stations also affect the overall revenue of the power station. Therefore, how to manage and utilize energy to maximize utilization efficiency is also a problem that needs to be considered when renting roofs.

4、政府征收拆遷補償問題：根據《國有土地上房屋征收與補償條例》規定，政府征收拆遷停產停業補償對象是被征收人，也就是房屋產權所有人，租用方不能直接向政府索要賠償。光伏電站依附于房屋建筑，國家對房屋進行征收和拆遷，因此停產停業損失補償應該包括光伏電站停產的損失補償，但光伏電站應該證明其自身存在經營行為，具有營業執照和相關手續，以證明該項目和經營的合法性，同時還需要證明光伏電站的價值，以及現有和未來的收益情況。再有需要解決的就是補償到位后，出租方和承租方如何進行分配的問題。

4. The issue of compensation for government expropriation and demolition: According to the Regulations on the Expropriation and Compensation of Buildings on State owned Land, the compensation object for government expropriation, demolition, production and business suspension is the expropriated person, which is the owner of the property rights of the house. The lessee cannot directly demand compensation from the government. Photovoltaic power stations are attached to buildings, and the state expropriates and demolishes buildings. Therefore, compensation for losses caused by the shutdown of photovoltaic power stations should include compensation for losses caused by the shutdown. However, photovoltaic power stations should prove their own business behavior, have a business license and relevant procedures to prove the legality of the project and operation. At the same time, it is necessary to prove the value of photovoltaic power stations and their current and future income situation. Another issue that needs to be addressed is how to allocate between the lessor and lessee after the compensation is in place.
