The impact of photovoltaic panels on high-rise buildings

Building-integrated photovoltaic (BIPV) technology is one of the most promising solutions to harvest clean electricity on-site and support the zero carbon transition of cities. The combination of BIPV and green spaces in urban environments presents a mutually advantageous scenario, providing multiple benefits and optimized land usage.

The development of dvPVBEs holds great potential for high-rise buildings with substantially glazed facades in modern cities. In this paper, we propose a new type of dvPVBE derived from motorized blinds that exhibits extraordinary flexibility, superior architectural aesthetics, and notable energy-saving potential.

With qualified building surfaces filtered by annual solar irradiation, strategies can be proposed to select building surfaces that have higher solar energy harvesting potential without imposing a negative visual impact or even trying to generate positive visual impact with innovative BIPV design at the same time.

PV glazing could be paired with rooftop solar to increase the amount of electricity generated, with the potential to create more power than a building needs by using high-efficiency PV windows and unique building geometry, the researchers noted.

6 FAQs about [The impact of photovoltaic panels on high-rise buildings]

Do rooftop photovoltaic solar panels affect urban surface energy budgets?

Our study also reveals that rooftop photovoltaic solar panels significantly alter urban surface energy budgets, near-surface meteorological fields, urban boundary layer dynamics and sea breeze circulations.

How do photovoltaic modules affect electricity generation efficiency?

Four different angles (18°, 45°, 60°, and 90°) of PV module layouts are designed, and simulation results demonstrate their impact on electricity generation efficiency. Notably, a vertical arrangement (90°) of photovoltaic components on the building facade significantly reduces electricity generation efficiency.

Can solar panels be used in high-rise buildings?

Despite the city's subtropical climate and abundant solar energy resources, along with numerous buildings with potential for PV power generation, architects remain cautious about adopting extensive PV panels on the facades of high-rise buildings.

Can large-scale solar panels affect urban climates?

Comparative analysis with cities, such as Sydney, Austin, Athens and Brussels, supports these findings, providing valuable insights for policymakers on managing large-scale solar panel installations. Understanding these effects is crucial for balancing the benefits of renewable energy with its potential impacts on urban climates.

How efficient is a building integrated photovoltaic system?

In [ 78, 79 ], the authors develop an experimental study of a Building-Integrated Photovoltaic system combined with a water storage tank prototype. The authors achieve a thermal efficiency of nearly 8% during the winter and 40% during the summer.

Does installing solar panels on a roof reduce energy consumption?

Several studies have found that installing PVSPs on a building’s rooftop lowers the yearly energy consumption of the ACS 15, 16. This makes logical sense given that the PVSPs provide shade from direct sunlight. As a result, only a fraction of the solar load that would normally travel through the roof surface is received by the buildings.
