Are solar photovoltaic systems environmentally friendly?

The generation of solar photovoltaic systems does not cause any type of pollution and requires no energy consumption. Solar photovoltaic is not subject to regional restrictions; thus, land resources can be saved. However, non-green issues also exist in green solar energy technology.

Are PV systems eco-friendly?

PV systems cannot be regarded as completely eco-friendly systems with zero-emissions. The adverse environmental impacts of PV systems include land, water, pollution, Hazardous materials, noise, and visual. Future design trends of PV systems focus on improved design, sustainability, and recycling.

Does solar PV generate enough energy in Chongqing?

As seen in Fig. 3, simulation results indicate that solar PV generates an enough energy in the city of Chongqing and is acceptable for use for the whole year. However, power generation decreased in December owing to lower solar irradiations.

How to maintain solar panels in China?

The authorities could explore implementing the manual method of maintaining PV panels in China, where human resources are very inexpensive. PV panels must be cleaned three times per week and washed once per month in the locations surveyed to retain their effectiveness.

Can PV systems be integrated with shading systems?

Freitas et al. (n.d.) proposed the integration of PV with shading systems such as tents and umbrella as embedded system where visual impact is an issue. In the future, PV systems design will suits better our daily life by meeting the requirements of visual esthetic and public acceptance (Hong, 2019).

Will PV production reduce environmental impact in China?

Given the seemingly permanent market shift towards Chinese production, these learning rates are best applied to the impacts estimated for the PV production in China (as described above) to estimate future impacts. This yields projected reductions in environmental impact of 8–34 % between 2015 and 2025.
