The Optimum Tilt Angles and Orientations of PV

The tilt and azimuth angles of a photovoltaic (PV) array affect the amount of incident solar radiation exposed on the array. This paper develops a new mathematical model for calculating the optimum tilt angles and azimuth angles for building-integrated photovoltaic (BIPV) applications in Hong Kong on yearly, seasonal, and monthly bases.

General method to obtain recommended tilt and azimuth

In Hong Kong, if a PV system is to be installed at the angles optimum for annual or cooling season, the system is limited to a single combination of tilt and azimuth angles, as listed in Table 3. The annual and cooling-season optimum azimuth angles by the clear-sky model are due south because ideal solar irradiance is symmetrical about solar

6 FAQs about [Hong Kong azimuth energy]

How much energy does PV system use in Hong Kong?

According to the results of the Study, the total estimated installed capacity of PV systems was around 6.29 MW in Hong Kong as at end of March 2017. The estimated annual generated energy by PV systems was about 6.29 GWh, and accounts for about 0.014% of the annual electricity consumption of Hong Kong in 2016.

Can PV technology expand the scope of solar energy generation in Hong Kong?

These innovative applications of PV technology present an opportunity to broaden the scope of solar energy generation in Hong Kong. As the city explores ways to diversify its energy sources, the integration of PV technology across various sectors offers a strategic pathway to augment the city's renewable energy matrix.

What are the opportunities for PV technology in Hong Kong?

The opportunities for PV technology in Hong Kong, however, extend well beyond BIPV. Innovative applications such as floating PV systems make use of water bodies, avoiding the land constraints of a densely populated city. These systems can reduce water evaporation and improve panel efficiency through the cooling effect of the water.

How much does PV installation cost in Hong Kong?

It is also observed that there is a downward trend of the cost of PV installation in Hong Kong. According to the market survey conducted in early 2018, the average installation cost of PV systems was about $47,000/kW (for common PV systems without complicated builders / structural strengthening works) and the payback period was about 40 years.

Can building-integrated solar PV systems help Hong Kong achieve a low-carbon future?

These projections account for 12.68%–16.32% of Hong Kong's total electricity consumption in 2022. This study underlines the substantial role of building-integrated solar PV systems in Hong Kong's transition towards a low-carbon future, offering valuable insights for policymaking and implementation strategies.

How much solar radiation can a roof receive in Hong Kong?

In Hong Kong, the total area of building roofs amounts to 26.08 km 2, which receives an average annual solar radiation reception of 1.54 × 10 6 Wh/m 2, resulting in a physical potential of 4.00 × 10 13 Wh for roofs. This constitutes 13.9% of the total physical potential of building PV (see Fig. 5).
