Should or not install solar power?
Each year electricity prices tend to increase, in the summer electricity consumption can increase by 30% to 50%. Therefore, the solution using electricity from solar energy is considered to be the most optimal and most economical power available today. A question that is always concerned and posed by many people before installing solar power is whether to install solar power? The following article, G7solar will help you to answer this question.

Solar power concept?
Solar power really saves electricity like rumors

How is the actual use of solar power?
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.
Prolonged sunny weather is a favorable condition to install solar power
The efficiency of solar cell power generation will vary depending on the number of sunny hours between regions. In particular, the South and the Central are the places with the most sunshine, while the Northern provinces have unstable amount of sunlight, only the summer months are the strongest and the other months the sun will be very weak, making you not have enough electricity. to use.
