Corruption of government officials exists in any country. No country is completely immune to it. It cannot be solved simply by legal means and requires a lot of political wisdom. As for your comment about presidential corruption, I think that is your personal opinion.
My English is terrible, and machine translation cannot express my views with complete accuracy. So, I can't do any more discussion.

Although Pakistani home solar systems originated in China, it is less expensive than China. This is a normal thing. There are two main factors that contribute to this phenomenon.
1. The market for home solar systems in China is very small. Electricity is very cheap in China. The vast majority of urban residents live in buildings, they do not have the conditions for installation.
2, Labor costs in China are much higher than those in Pakistan. In terms of installation cost of home solar system, the price in China is about 3500~5000 RMB. This does not include its labor cost in the manufacturing process.
Constrained by these factors, the utilization of solar home systems in China is very low.
About the Chinese electricity price
China implements dynamic electricity prices. Prices are completely different during peak or trough periods. In my city, the price varies between RMB 0.15~0.56/KWh. It is controlled by the automatic power management system of the national grid. My house's monthly electricity bill varies between RMB 80~400, and when it is hot in summer and cold in winter, this difference is caused by the use of air conditioning. This fee is negligible compared to the income of the average Chinese.
