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.

PWM Regulator

Wholesale PWM Regulator (solar charge controller)

Pulse width modulation (PWM) regulator is essentially a switch(aka. Solar Charge Controllers) that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.

PWM is arguably the most effective means to achieve constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’s condition and recharging needs.

Advantages of PWM Charge Controllers for PV Systems?

Charging a battery with a solar system is undeniably a difficult challenge.

In the past, simple on-off regulators were used to limit battery outgassing when a solar panel produced excess energy. However, as solar systems matured, it became clear how much these simple devices actually interfered with the charging process.

The history of on-off regulators has been full of battery failures, increasing load disconnects, and growing user dissatisfaction. PWM has recently surfaced as the first significant advance in solar battery charging.

PWM regulators make use of technology that is similar to other modern high-quality battery chargers. When a battery voltage reaches the regulation setpoint, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery — and yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result of this is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.

Additionally, the PWM charge controller promises some very interesting and unique benefits. These benefits include:

  1. Ability to recover lost battery capacity and de-sulfate a battery
  2. Dramatically increase the charge acceptance of the battery
  3. Maintain high average battery capacities (90%–95%), compared to on-off regulated state-of-charge levels that are usually 55%–60%
  4. Equalize drifting solar battery cells
  5. Reduce battery heating and gassing
  6. Automatically adjust for battery aging
  7. Self-regulate for voltage drops and temperature effects in solar systems

A great deal of testing and data supports the benefits offered by PWM regulators. Additionally, manufacturers are continuing their own ongoing test programs to refine the PWM charging technology. As a result, over time, each of these benefits will undoubtedly be improved and more clearly defined.

Are All PWM Chargers the Same?

Many solar charge controllers that simply switch FETs differently than the on-off algorithm claim to be PWM regulators. Buyers should be aware of this because this is actually not true. Only a few controllers are actually using a PWM constant voltage charging algorithm. The rest are switching FETs with various algorithms that are cheaper and less effective.

Why Buy Wholesale PWM Regulators for PV Systems from Us?

Our website lists PWM regulators for PV systems from reputable brands all over the world. As a result, you can expect that the PWM regulators that we offer are of the best variety. They are characterized by higher efficiency, reliable power voltage, and a   longer life span, thus giving them the ability to fulfill all your solar power needs.

If you want to buy PWM regulators for PV systems at low wholesale prices, then go through our website to explore products with profitable deals. You can also choose to send in your query at info@www.solarfeeds.com.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.

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.
