Optimal design of rooftop solar power system:
To invest without loss of capital
In 2021, after a massive wave of investment in solar power, many investors complain because the actual power output is very low compared to the designed output. The standard design and technical optimization of the Rooftop Solar Power system for a reasonably profitable investment is something investors should pay close attention to. Especially when the FIT3 price will be low and the grid electricity purchase price is likely to increase from 2021.
Cheap price, low quality when trusting suppliers too much
In 2020, the installation price of a fixed solar power system from reputable suppliers is in the range of 15-21 million/kwp. However, the market is full of solar power offers of only 11-2 million/kwp. In fact, the price for a solar power system depends greatly on the quality of the panels, the inverter, the design and the installation technique of the system.
To reduce costs, many suppliers use panels and inverters of unknown origin and poor quality. They minimized the panel support system, even drilling straight into the panel to fix it to the roof frame. As a result, consumers cried out when the system capacity was not at all as it was offered for sale. Even worse, when the system fails, the consumer cannot be covered by the warranty because the panel has been drilled by the installer.
How to properly design and install a solar power system?
To make sure the solution provider is properly installed, you can check to make sure the system is properly implemented.
Fixed solar power system properly installed
Ideal roof for solar power system 50m2 or more, unobstructed – obscured, facing south or north, inclined at 30 degrees. A framing system is required to adjust the inclination for flat roof structures that are little or too steep.
East or west-facing structures will definitely need to be more carefully calculated so that the distance between the panels is reasonable, so that they do not obscure each other when the sun changes direction during the day.
Rotational solution helps the panel get the most sunlight
Rotating axis technology helps position the panel perpendicular to the sun’s rays. The amount of sunshine obtained reaches 6-7 hours of sunshine/day compared to 3-4 hours of sunshine/day of properly installed fixed systems.
SolarPlus rotating axis solar power system
After investing in research and development, SolarPlus Joint Stock Company has standardized modules and successfully launched SolarPlus Econo rotating axis products for solar power. For the first and only time in Vietnam, there is a pivoting system that operates precisely thanks to AI technology, a durable mechanical system that can withstand harsh weather and is still compact enough to be installed on roofs. Vietnam.
With the modular design, consumers can rest assured that the system can be easily installed with the correct technique and achieve the desired high performance.

SolarPlus smart solar power system also has many other advantages worth considering. As the power monitoring and monitoring software comes with the system, it helps to ensure the desired performance. Or the automatic cleaning and cooling system helps to save significant cleaning, maintenance costs, because it only needs to be cleaned once a year, unlike the fixed system up to 4-6 times a year.
Hopefully, in the near future, when solar power is replicated in Vietnam, quality systems such as SolarPlus system will be widely introduced to consumers as an economical and reliable choice.
