Solar Market Outlook in Philippines

The Philippines’ growing solar market is due in part to the Philippine Energy Plan that has outlined the policies and steps needed for the country to reach its target of 20 GW renewable energy by 2040 (or 15 GW by 2030). As of 2021, the country’s solar energy generation capacity is at 1.2 GW. 

The solar power market in the Philippines takes on a liberal approach. It is also regulated through the Republic Act No. 9513 that promotes the development, utilization, and commercialization in the harnessing of renewable energy sources in the country. 

With the power consumption in the Philippines forecast to grow with a compound annual growth rate of 5.8 percent, the government believes in the importance of increasing its power generation capacity as well. Since the country does not import electricity, it is important that alternative sources be looked into in order to cope with the demand. Its tropical location that provides year-round access to sunlight makes solar power a valid option as a renewable energy source. The government has already expressed its plan to deploy more solar PV installations in order to reach its target solar capacity by 2030, as outlined in the National Renewable Energy Program. 

Solar Energy Equipment Supply Capacity in Philippines

There are several manufacturers of solar power equipment in the Philippines. For those looking for more options, you can find plenty of online and global distributors and suppliers.

Top 8 Major Seaports & Logistics in Philippines

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.
