Taiwan mandates solar power on new buildings, addressing safety and cost concerns

Taiwan is set to implement new regulations mandating solar power installations on new buildings beginning August 1. This initiative is projected to add approximately 660 MW of installed capacity each year, potentially spurring a new wave of solar energy development.

The Solar Photovoltaic Sustainability Association has moved to alleviate public concerns regarding safety, the potential for construction costs to be passed on to housing prices, and ongoing maintenance. The association asserts that the new regulations include rigorous standards to address these issues. Unlike simple rooftop additions, the new rules emphasize structural integrity, requiring photovoltaic modules to withstand wind loads equivalent to level 17 typhoons. System structures must be certified by professional engineers, ensuring high resistance to weather conditions.

In cases where external power grids fail due to natural disasters, buildings equipped with solar power and disaster-resilient energy storage can maintain essential electricity for daily life, effectively transforming into "distributed micro-power plants." The regulations also mandate biennial structural and electrical inspections for the systems to ensure continued safety.

Regarding concerns about increased housing prices, the association notes that the cost of solar system installation represents less than 1% of a modern building's total construction cost. Solar power systems have a "self-repaying" characteristic, with initial investments expected to be fully recovered through green energy certificates or power purchase agreements. The revenue generated over the system's lifespan, often exceeding ten years, will then contribute to the community's public fund, positioning the installations as a "green asset upgrade" that can enhance property value.

To prevent solar equipment from becoming obsolete due to issues like inverter damage or lack of maintenance, the association highlighted that solar equipment is now officially included in standardized contracts for new and pre-sale homes. Developers must complete the change of installer registration and provide documentation, including electrical installer and professional engineer certifications, before handing over the equipment to the property management committee or owners. This ensures clear responsibility for management and a thorough process for acceptance and subsequent upkeep.
