Tunisia

Tunisia: General overview of the solar market

Tunisia, a country in northern Africa, is heavily dependent on natural gas and oil. Only 3% of the energy mix stems from renewables. Consequently, it is accurate to say that Tunisia’s solar market is something to worry about. Nevertheless, there is hope if recent developments in Tunisia’s energy sector are anything to go by.

There are no precise statistics concerning Tunisia’s current installed solar capacity. As of 2016, a meager 15 Megawatts of solar energy was connected to the national grid. However, solar projects totaling 1000 Megawatts are currently in progress. There is room for further growth, considering that the country has excellent solar radiation potential.  

Recently, the Tunisian government formulated a new legal framework and measures to support the country’s solar market. Some of these measures include the initiation of empowering policies and establishing guarantees to encourage solar energy development.  There is no doubt that the Tunisian solar market will continue to grow and generate lucrative opportunities for solar installers and professionals.

The state of solar equipment supply in Tunisia

There are a substantial number of solar equipment suppliers operating within Tunisia’s solar market. Still, most of these entities can only manufacture and distribute equipment for small and medium solar projects. So, you may have to import solar equipment for large-scale solar projects.

The country boasts of several ports and a healthy transportation network. Therefore, you can easily import solar equipment from any of the leading brands worldwide. Where can you find a reliable solar equipment supply partner?

Well, Solarfeeds is the leading e-commerce marketplace for solar equipment brands worldwide. Consequently, we offer the most competitive quotes across 50 categories of solar equipment. Just visit our inquiry page, place a request and prepare to be amazed.

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.
