Portugal

An Analysis of Portugal’s budding solar market

During the forecast period 2020-2025, it is expected that the solar market in Portugal will grow at an annual rate of more than 8 %. Rising energy demand, efforts to reduce our reliance on fossil fuels, and declining costs of solar PV and associated systems are among the primary drivers of the market.

The solar energy market is also driven by factors such as rising demand for renewable energy, rising investments in solar farms, and government policies. In the coming years, the market for wind energy will likely be restrained by the increasing adoption of an alternate clean power source like the wind.

The Portugal solar market is expected to grow at a significant rate due to ongoing efforts by the Portuguese Government and their future policies.

Portugal’s solar equipment production and supply capacity

The Portuguese market is home to several suppliers and manufacturers of solar equipment. Solarfeeds is the best place to buy solar equipment. Solar equipment brands from around the world are available in our online marketplace. We offer quality equipment for an affordable price, so you can choose us. 

Seaports and logistics services in Portugal

There are several seaports in Portugal, such as:

  • Lisbon
  • Sines
  • Faro
  • Porto
  • Vila Real de Santo a
  • Coimbra
  • Ptlzi
  • Constanzia

If the need arises, you will not have a problem importing quality solar equipment. After arriving at the port, the equipment can be safely transported to the project site using any of Portugal’s leading logistics companies, including 

  • Torrestir
  • MSC
  • Pinto Basto
  • TIBA
  • Navex
  • Orey Shipping
  • Portocargo
  • Euroatla

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.
