Recently, DAT Solar has just completed the deployment of a solar power system for Phuong Hau rubber production company in Binh Phuoc. With a capacity of 982.8kWp, this clean energy system can generate electricity output of up to 1.6GWh/year. With the current widespread electricity shortage, this will be a sizable contribution to society if this model is replicated more widely. Especially for enterprises in the Central and Southern regions, each 1kWp of investment system can generate an average of up to 5kWh of electricity per day, much higher than the common level of other countries in the world.

In order for a solar power system to generate a superior amount of electricity compared to the same investment cost, engineers need to combine many different specialized optimization solutions. Without exception, DAT Solar engineers have “tailored” the system based on all possible factors affecting performance. Some methods can be mentioned such as balancing the distance of panels compared to the roof to avoid high temperatures affecting performance, calculating the number of panels per row for inverter to achieve high efficiency threshold but still be durable, estimate the power output in reality to arrange the inverter system appropriately, avoiding excess causing waste or lack of inverter capacity causing loss of power output in the future. Besides, it is also very important to choose panels with technology suitable for Vietnam’s climate, for example, Half-cut cells technology on Canadian Solar solar panels will help reduce voltage, making the panel cooler when operating, thereby increasing the efficiency of photovoltaic conversion. Besides, this factor also helps the battery has a longer life than usual.

According to data from sales engineer DAT Solar, the number of newly installed solar power systems is increasing significantly day by day, now has increased by more than 10 times compared to the same period last year, bringing the total capacity that DAT Solar has deployed up to 20MWp. One of the reasons why rooftop solar power is favored by many enterprises today is the high economic efficiency of this type of clean energy.

In addition to contributing to the community to protect the environment, using solar power also helps enterprises reduce most of their production costs, thereby increasing competitive advantages. Sharing about this issue after applying solar power to production, Mr. Nguyen Van Phuc, director of Phuong Hau rubber production company said: “Installing solar power gives me a few hundred million every month. Save every month on production costs to compete with others!”
