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.

Power Optimizers

What are Power Optimizers for Solar Inverters?

Power optimizers are additional devices used in Solar Power generation to convert DC to DC (that’s right, not a typo, DC to DC). Power optimizers tune the performance of individual panels in the Solar power plant. 

Optimizers are required because the photoelectric effect does not produce the same energy in all the panels equally. Factors like the shading of panels due to clouds and dust can result in non-uniform distribution of power.

What are the types of Power Optimizers for Solar Inverters?

Module-level Power Optimizer: Power optimizers at each module level optimize the energy distribution to negate the effect of peculiar conditions.

Sometimes the panels don’t operate at the optimal power efficiency. In that case, the module measures the maximum power point tracking. MPPT helps to optimize the DC characteristics to get the maximum possible power output.

In Solar Power plants, the panels get connected in series. Therefore the reduced output from a few panels can lead to the reduced power output power of the whole system. 

Sometimes up to 50% of power is lost. Power optimizers become critical for not only optimizing the output DC power. But also save the system from power loss of up to half of the capacity.

How do the Power Optimizers for Solar Plant work?

Large Solar plants face an efficiency dip in power production and delivery of the power to the load. Solar Inverters convert DC to AC for the consumers. 

The DC input to the inverters is not consistent without an optimizer. Power optimizers use maximum power point tracking to make the DC power output from panels optimal.

This optimal DC power is fed to the Solar Inverters to get the efficient flow of current at optimal levels. Smaller DC voltage is hard to convert into AC voltage. Power Optimizers are necessary, especially for big Solar power plants.

What are some top brands of Power Optimizers for Solar Inverters?

SolarEdge produces high quality PV modules for Power Optimization in the Solar Inverters.
