1. According to Article 3 of the "Standards for Exemption from Obtaining Miscellaneous Licenses for Installing Renewable Energy Facilities" promulgated by the Ministry of Economic Affairs, "the buildings referred to in this standard refer to those that have obtained the construction license and its use license in accordance with the provisions of the Construction Act, or before the implementation of construction management , a legal building that has been completed.” 2. If the building with an additional roof (including iron sheet house) cannot obtain a usage license issued by the construction authority (it is an illegal building), solar power generation equipment cannot be installed. In addition, for legal buildings that have been completed before construction management is implemented, most construction authorities authorize local governments to identify and issue certification documents for water and electricity connections. In this case, solar power generation equipment can be installed. 3. Buildings under construction can apply to install solar power generation equipment in accordance with the above regulations. However, during the parallel operation stage, they need to be connected to the power supply line for actual testing. If the building construction period is very long, it may not be able to meet the requirements of "renewable energy power generation". When applying for equipment registration with the central competent authority as stipulated in the "Equipment Installation Management Measures", it is recommended to fully communicate with the installation operator during the parallel review and preliminary negotiation stages, and remind the operator to pay attention to the time limit in the review opinion letter.

The free part refers to the exemption of "grid connection engineering fees", that is, Taipower will absorb the cost of the existing power grid reinforcement part by itself, and the applicant does not need to pay. In addition, the solar photovoltaic power generation equipment and connecting power cords should still be purchased and installed by the applicant.
