[PDF Version]By the end of 2022, China's cumulative installed PV capacity had reached 392.6 GW, with an additional installation of 87.41 GW in 2022 (National Energy Administration, 2023), ranking the first globally in terms of new installation rate. It has become the world's largest PV power market, accounting for nearly one-third of global PV installations 9.
The increased installed capacity, the heavy manufacturing, and the availability of materials on its domestic land allowed China to control the global solar market by imposing quotas and restrictions on importing countries. We have shown that China alone installed more than 50 % of the total Asian solar capacity in the span of 25 years.
Regarding the installation, China is striving to lead that as well. The Renewable Energy Agency's updated report shows that solar PV installation increased from 72 GW in 2011 to more than 1 TW by the end of 2022 (IRENA, 2022b). China's share in production increased from 60 % in 2010 to almost 80 % in 2021.
All these factors allow China to provide cost-competitive manufacturing for all solar PV elements, especially since the material cost is unified. That being said, PV manufacturing is 9 % higher in India, and about 20–35 % more expensive in the United States, Europe, and Korea (IEA, 2022a).
As discussed in the previous sections, China was able to dominate the solar industry market. Incentives and government subsidies dating from 2009 onwards helped secure the lead in the world for solar power production since 2017 (Liu et al., 2022; Chowdhury et al., 2020).
China alone produces at least 80 % of the main components of PVs. Also, more than 30 % of the cumulative installed capacity is in China, the top exporter of manufactured solar PVs in the World with competitive manufacturing costs that reached less than $0.24/W.

You need a solar charge controller to connect the panel to the battery, otherwise, the panel would potentially over-charge the batteries (though their BMS should protect them) and you would definitely over-volt the inverter due to the panel's Vmp/Voc value.
If the solar panel produces more power than the battery can handle, the battery can overcharge and be damaged. A charge controller helps prevent this from occurring. Divide the solar watt rating by the voltage of your battery. You can usually find the voltage listed on the battery itself.
To set up a functional solar charging system, you need a few essential components: a solar panel to absorb energy from the sun and convert it into electricity; a charge controller to regulate the amount of electricity flowing into the battery to prevent overcharging or undercharging; and a battery to store the electricity.
Leave the battery on the connector until it's charged. The length of time it will take to charge your battery will depend on the size of the battery you're using, the wattage of the solar panel, and even the weather that day. That's where your digital display will come in handy.
Connecting a solar panel directly to a battery can cause a number of concerns, including overcharging, which can harm the battery. For instance, a 12-volt lead-acid battery requires 13.5 to 14 volts to charge correctly; however, when exposed to direct sunshine, a solar panel may generate up to 23 volts.
Flow Regulation via Charge Controller: (DC) electricity generated by the solar panel is routed through a charge controller before reaching the battery. This controller is essential as it regulates the voltage and current, ensuring they align with the battery's specifications to prevent overcharging or undercharging.
Warning: In order to prevent a sudden surge from damaging the charge controller, it's best to connect the battery before the solar panel. Slide the ends of the wires into the input ports on the charge controller. The ends of the wires that plug into the charge controller typically will not need to be fitted with any type of a connector.
