Abstract

The traditional point of view suggests photovoltaic systems to be installed at the optimum angles. However, various reasons require more flexible photovoltaic installations, especially for building-integrated photovoltaics. Some site-specific cases based on local irradiance data show that small deviations from the optimum will not cause big energy losses, while more theoretical insights on the flexible installation problem are required to achieve higher photovoltaic penetration. This paper tries to demonstrate that quite a large range of photovoltaic installation angles causes ignorable energy losses annually. Furthermore, this paper developed and validated a universal and convenient Loss Bound Equation to determine the 5% Loss Bound worldwide with high accuracy. The 5% Loss Bound is defined as a group of tilt and azimuth angle combinations where the plane-of-array energy losses are limited within 5% of the annual maximum plane-of-array irradiation. The universal Loss Bound Equation is independent of local irradiance data, which is totally different from conventional irradiance-based approaches and it is significantly faster and more convenient to use. The 5% Loss Bound will provide great flexibility for planning array spacing, decreasing dust deposition, sustainable retrofits to existing buildings, design for building-integrated photovoltaics, and so on.
