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.

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.

Zimbabwe

Solar Market Outlook in Zimbabwe

The Zimbabwe government has recently launched its National Renewable Energy Policy. They have obtained assistance from the World Bank in order to procure large scale solar PV projects. The World Bank has opened a tender via the African Power Platform in order to boost the renewable energy capacity. 

Solar is the primary source of energy among independent power projects in Zimbabwe. As of July 2021, there were seven new solar PV projects that were installed with a solar capacity of 66 MW. These projects are expected to become ready and fully functional by the end of 2021, which should boost the country’s solar and renewable energy industry. 

The new solar developments are also proof that there are adequate regulations in place in Zimbabwe designed to benefit investors and consumers alike. The government is hoping to maintain policies that will encourage more investors in the future. 

By the end of 2020, Zimbabwe has reached 17 MW capacity in solar installations. They are targeting to reach 1GW of capacity by 2025. 

Solar Energy Equipment Supply Capacity in Zimbabwe

As of now, there are limited options for suppliers and distributors within Zimbabwe. Individual and commercial consumers of solar installations do have access to global suppliers, as well as those from neighboring countries. 

Top 8 Major Seaports & Logistics in Zimbabwe

There are various ports and logistics companies operating in Zimbabwe to maximize the ability to transport solar power equipment. The top ports available in Zimbabwe are

• Chiredzi,
• Thompson Junction,
• Rusape,
• Harare,
• Victoria Falls,
• Mutare,
• Bata, 
• Hwange.
