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.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

What is Solar Energy in Germany?

Germany, despite being a sun-drenched country has been considered as one of the highest solar power outputs around the world and still possesses the most advanced and latest research about solar energy and has many new industry actors. Moreover, they’re expecting for the second wave of solar power expansion, which will soon bring success and progress for the solar technology’s full systemic integration.

For several years, Germany has been considered as the world’s top PV installer among other countries. At the end of the year 2016, Germany managed to build a total installed solar power capacity of 41.3 gigawatts (GW) which was behind China’s solar capacity.

Most solar power in Germany exclusively consists of photovoltaics (PV) systems only. Germany has only a little interest in concentrated solar power (CSP) for it does not use photovoltaics and this solar technology requires much higher solar insolation as compared to the PV system. However, there is still an experimental CSP-plant with 1.5 MW capacity which is being used solely for on-site engineering purposes only rather than for commercial electricity/power generation. This concentrated solar power is called the “Jülich Solar Tower” that is owned by the German Aerospace Center.

Moreover, in 2014, Germany managed to install about 1.5 million photovoltaic systems across the country which are ranging from small rooftop solar power systems to medium commercial and large utility-scale solar plants and farms. The largest solar farms of Germany are located in Neuhardenberg, Templin and Meuro with solar capacities of over 100 MW. Moreover, these PV technologies were accounted for an estimated 6.2 to 6.9 percent of Germany’s net electricity generation in the year 2016.

However, new installations of photovoltaic systems have slowed down steadily since the beginning of the year 2011. Also, it was estimated in the year 2017 that over 70 percent of the employment in the solar industry of the country have been lost in recent years. Solar power in Germany has gone through rough times since it has been started in the wake of Germany’s Renewable Energy Act in the year 2000. However, German companies quickly loomed to global leadership in solar power technology before a collapse in the solar industry happen and some of the companies were forced to hold their businesses.

Proponents from the Photovoltaic industry blamed the government for its lack of commitment in the said industry, while others point out that the loss of jobs in the solar sector is due to financial burden that was associated with the fast-paced launching and manufacturing of photovoltaics, which in their perspective was very unsustainable to the transition of renewable energies.

With all of these, still, the official governmental goal of Germany is to continuously improve and increase the contribution of renewable energy to the country’s overall electricity generation and consumption. By 2020, Germany is aiming for a long-term minimum target of 35 percent capacity, 50 percent by 2030 and around 80 percent power capacity by the end of 2050.

Currently, the country is significantly producing more electricity at specific times with high solar irradiation than the country’s needs, slowing down spot-market prices and exporting the country’s electricity surplus to nearby countries. In 2014, the record of exported electricity surplus reached almost 34 TWh. The decline of spot-prices in the market may raise the electricity prices for retail customers, as the expansion of the guaranteed feed-in tariff and spot-price increases as well.

As the combined share of fluctuating wind and solar energy is nearly achieving 17 percent of the national electricity mix, energy issues and problems are also being prevented and others becoming more manageable. This is because of the electrical grid adaptation, new grid-storage capacity construction, reduction of fossil fuels, altering of nuclear power plants and constructing a new generation of combined heat and power plants. Today, nuclear power and brown coal are the cheapest suppliers of electricity in Germany.
