China

Solar Energy in China Overview

As of right now, China is the world’s largest market for both photovoltaics and solar thermal energy. In addition to that, China has also been the world’s leading installer of solar photovoltaics, and in 2015, they became the world’s largest producer of photovoltaic power, just narrowly surpassing Germany. Moreover, China was the first country to pass 100 GW of cumulative installed PV capacity, and by the end of 2018, that number peaked at 174 GW.

By May 2018, China holds the record for the largest operational solar project with their 1,547-MW project at Tengger. With that said, the contribution to the total electric energy production remains modest as the average capacity factor of solar power plants is relatively low at 17%. Additionally, of the 6,412 TWh electricity that was produced in China in 2017, 118.2 Twh was generated by solar power, which is equivalent to 1.84% of total electricity production. With all these statistics, it is China’s goal to reach 1,300 GW of solar capacity by 2050. If this goal were reached, it would be the source with the largest installed capacity in China.

Aside from solar photovoltaics, solar water heating is also extensively implemented, with a total installed capacity of 290 GWth at the end of 2014. This represented about 70% of the world’s total installed solar thermal capacity.

Charge Controllers

Wholesale Solar Charge Controllers Suppliers

Sometimes called “Solar Regulators“, a solar charge controller is basically a device that controls voltage or current that charges the battery so that electric cells do not get overcharged. A charge controller controls the voltage and current coming from the solar panels and move to the electric cell. 

Roughly, 12V boards or panels generate around 16 to 20V, and without any regulation, the voltage will damage the electric cells through overcharging. Usually, electric storage devices need nearly 14 to 14.5V to get fully charged. The solar charge controllers are available in different features, sizes, and costs. The range of charge controllers starts from 4.5A, 60 to 80A.   

Why Charge Controllers for PV Systems?

  • To protect the battery (12V) from overcharging
  • To minimize system maintenance and increase the battery life
  • To indicate auto-charge
  • To monitor the reverse current flow.

Solar power systems mostly use 12V batteries. Solar panels can carry more voltage than required to charge the battery. Charge controllers can keep the voltage of the electronic storage at the optimum level. 

This way, solar systems work at their best efficiency level. By running higher voltage in the wires from the solar panels to the charge controller, power transmission through the wires is reduced.

Types of Solar Charge Controllers

There are three main types of solar charge controllers:

  • Simple 1 or 2 Controls: This type of charge controller has shunt transistors to control the voltage in one or two steps. The controller regulates the voltage in the solar panel after reaching a certain point.
  • Maximum Power Point Tracking (MPPT): The MPPT solar charge controller identifies the best working voltage and amperage of solar panels and matches that with the electric cell bank. The outcome is additional 10-30% more power output than other controllers.
  • PWM (Pulse Width Modulated): These are the conventional types of charge controllers and are currently considered as the industry standard.

Get the Best Quality Solar Regulator from SolarFeeds

As a multiple wholesale vendor eCommerce marketplaces, our website lists a wide range of reputable brands of Solar PWM/MPPT Charge Controllers from manufacturers. These charge controllers perfectly work as electronic DC-to-DC converters that optimize the match between the solar array (PV panels), the battery bank, or the utility grid. 

The charge controllers convert a higher voltage DC output from solar panels into the lower voltage needed to charge batteries. 

You can also buy wholesale multifunction solar charge controllers, which are based on Microcontroller technology. These multifunction solar charge controllers have become popular for their excellent performances. They are used to convert regular UPS/inverters into a Solar power Conditioning Unit (PCU).

Check out our website for various wholesale solar charge controller manufacturers, and buy them in bulk at a low cost. 

You can get long-term benefits from buying wholesale solar charge controllers directly from manufacturers for expanding your business and increasing revenues. Drop us an email with your questions at [email protected]
