Why is solar power in the Central Highlands extremely ”hot” in 2020?

With a very abundant amount of solar radiation every day and relatively stable throughout the year. According to the map of solar radiation in Vietnam, the provinces of the Central Highlands such as Kon Tum, Gia Lai, Dak Lak, Dak Nong have an extremely high number of sunshine hours of 5.1 - 5.3 hours/day. desirable figure for any solar power system owner.

Solar panels will generate more or less electricity depending on the amount of sunlight (photons) and the ambient temperature. Many people mistakenly believe that the higher the temperature, the more electricity the panel will produce. If you have a good understanding of how solar cells work, they generate electricity based on the light of radiation, not the heat of radiation. The higher the ambient temperature, the lower the photoelectric efficiency will be.

Combining both the time of the sun's rays per day and the average temperature per year, you can easily see the outstanding advantages of the provinces in the Central Highlands.

 

The Central Highlands provinces have the lowest population density in the country, according to the General Statistics Office, the Central Highlands area accounts for 16.1% of the country's area (with only 5 provinces), but the total population accounts for only 6.1% of the total population. country (most recent data 2019). With such a large land area, the houses here tend to have few floors (floors) and are very large, so the roof area is also relatively large.

In addition, with houses on the ground floor and built far apart, the roofs of the houses are not obscured from each other, which helps the rooftop solar panels operate at maximum capacity.

 

Currently, there are still many communes/districts in the Central Highlands that are still unstable in terms of grid power or even unable to connect to the grid. This greatly affects the lives of the people here.

Owners of livestock farms, coffee and rubber plantations...in the suburbs often face power outages or no grid power, but have to use diesel generators for daily living. irrigation water pump. Using gas-fired generators emits relatively high CO2 gas, causing environmental pollution and partly affecting plants.

Recent years have witnessed the strong development of the solar power industry, consumers benefit from price competition between businesses. The price of a solar system today can be 10 times cheaper than it was 10 years ago. Therefore, it is very feasible to equip a system of solar panels to replace diesel generators.

Not only me but also many householders and investors in the Central Highlands see the difficulties in power grids as well as the favors of nature for this place as I have analyzed above. Along with that is the encouragement from the Government with very good incentives for people to install rooftop solar power, which has made the solar energy market in the Central Highlands extremely hot recently.
