Solar power concept?

Solar power really saves electricity like rumors

According to Mr. Tung (living in Hanoi), he has invested 80 million VND in the installation of the 3 Kwp solar power system. He hopes to save on electricity bills as advertised by the suppliers. But reality is not as expected of him.

The amount of electricity produced from the solar panels did not meet the initial expectations. Like Mr. Tung quite a lot of people have such a situation. That means the amount of electricity produced is not stable, some days less, some days more. One of the customers is also worried that the initial cost cannot be covered, and there is a risk of capital loss.

To answer this problem, solar power experts said: In Vietnam, solar power is quite new, it is necessary to carefully consider factors such as the installation location where solar energy can be obtained. Is it convenient or not, or whether the number of sunny hours in the installation area is high or not, how do users need to use electricity…. Finally, it is necessary to calculate the interest rate and then decide to invest.

Solar PV installation depends on factors.
