Trinity s multi-crystalline photovoltaic panel planning

Why is LCA conducted on multi-crystalline silicon photovoltaic systems in China?

LCA is conducted on the multi-crystalline silicon photovoltaic systems in China. Multi-Si production is the most contributor to the energy demand and environmental impacts. Compared to other power generation systems in China, PV system is more environmentally friendly. Areas with higher solar radiation are more suitable for installing PV systems.

Why are polycrystalline silicon PV panels more expensive than monocrystalline PV panels?

It is mainly because the total environmental impact of the life cycle of polycrystalline silicon PV panels is higher than that of monocrystalline silicon PV panels, and the higher IPCE brings about the relatively higher cost of monocrystalline silicon PV panels.

Is a photovoltaic (PV) system environmentally friendly?

Compared to other power generation systems in China, PV system is more environmentally friendly. Areas with higher solar radiation are more suitable for installing PV systems. This study performs a life-cycle assessment for a photovoltaic (PV) system with multi-crystalline silicon (multi-Si) modules in China.

What is the environmental impact of monocrystalline silicon PV cells?

Chen et al. (2016) evaluated the environmental impact of the production process of monocrystalline silicon PV cells in China, which showed that due to the consumption of silver paste, electricity and glass, the impacts caused by human toxicity, marine ecotoxicity and metal depletion are dominant to the overall environmental impact.

What is the optimal solar irradiance for crystalline silicon PV modules?

Therefore, we evenly selected five values of solar irradiance and the price of crystalline silicon PV modules as variables, and achieved the Pareto optimal solution set, and compared the Pareto solution with the solar irradiance of 140 W/m2 as a basis for sensitivity analysis of different schemes.

Which scheme should be used in regional planning of solar photovoltaic technology?

Therefore, based on the comprehensive analysis of environmental and economic indicators, it is suggested that in the regional planning of solar photovoltaic technology, scheme ③ should be preferred, followed by scheme ② and scheme ①.
