WHO CAN ALSO BE "INVESTOR", WHY NOT?
With Decision 13/2020 / QD-TTg issued by the Prime Minister on a mechanism to encourage the development of solar power projects in Vietnam, many households in our country have become investors in these projects. this judgment.
BENEFITS INCREASED BY SOLAR POWER SYSTEM
- Let your roof generate money every day: from roofs, factories, vacant land …
- You absolutely do not need to worry about problems for installation and maintenance, we are all worried about every problem.
- Fast payback time is only 5-7 years, more than 20 years after that is profit for you. Payback times will be especially faster for provinces with high sunlight such as Da Nang City
- Reducing electricity costs, at the same time, is an investment opportunity to increase profits from selling electricity to EVN
- Shielding and increasing the aesthetics of the project
- Environmental Protection
- Reduce the power load for the national grid and improve the quality of electricity
DECISION NO 13/2020 / QD-TTG: HOA LAI SOLAR POWER PROJECT RECEIVED SUPPORT AND PROMOTION FOR DEVELOPMENT
Mechanism of electricity trading at resale price of residual electricity to EVN applying installed systems by 2020:
- Rooftop solar power is acquired at a price 1.943 VNĐ/kWh
- The selling price of solar terrestrial power to EVN is 1.644 VNĐ/kWh
- Floating solar power is acquired at a price 1.783 VNĐ/kWh

MORNING
When the sun shines on the solar panel system, it also collects energy, you will begin to save a large amount of electricity thanks to this energy source, even collect electricity refund if you do not consume all this abundant electricity (excess electricity to the grid).
DAYTIME
The more electricity your system generates and generates more electricity, the more profitable it will be with the attractive solar PV selling price to EVN at 2,086 VND / KWh (According to Document No. 1532 / EVN-KD)
NIGHT
The amount of electricity collected from the system accumulated on the grid during the day is recorded by a 2-way electric meter, partially offset the cost of the amount of electricity you use in the evening.
OF THE HOA LIEU SOLAR SOLAR SYSTEM
A grid-connected solar power system generates electricity from the sun and stores it in the grid, so you can use it any time you need it.
During peak hours, the system can generate more electricity than is needed to power your home. And if you use the residue, it can be sold to the utility company.
The structure of a grid-tie system will be simpler than a stand-alone system, so the installation cost is also much cheaper.
1. Solar panel (solar panel)
Here we use specialized panels for installation, which are high-capacity Mono 400W panels for high efficiency as well as somewhat limited installation space for the roof.
Using this category also helps you optimize your budget. Fewer panels mean less component costs such as cables, number of rails, and even maintenance costs.
2. Inverter Hoa grid
The electricity generated from the solar cell system is DC current, so these inverters are the equipment that converts DC power into AC for use.
Normally, we will choose the inverter’s capacity equivalent to the output capacity of the system.
3. Mounting accessories:
Includes electrical supplies for installation and operation of the system. The electrical materials will include: Electrical conductors, electrical cabinets, CBs, mufflers …
4. Frame system, rack for panels:
The bracket will act as a support, as a support for the panels on the roof or on the ground, helping to protect other components.
Rooftop mounts tend to cost less because they pre-use your roof structure. More flexible ground-based framing: you can build them anywhere in your space and direct your panels directly at the sun so they work at their highest output.
Roof
Roof mounted system costs less and space.
Frame truss under the ground
The frame-mounting system is more active in the installation direction for better energy capture.

Customer asks, patsolar.com answers (FAQ)
Question 1: Where should install solar power system?
Quick Reply: To optimize the cost of solar PV installations, a solar panel installation on the roof is the ideal solution. There are also many factors deciding on an effective installation location such as roof direction and inclination, space around the house, shade …
Question 2: How does shade impact solar panels?
Quick Reply: The phenomenon of sunlight obstructions such as trees, high-frequency buildings, dry leaves, bird droppings … has a very “strong” impact on the production efficiency of the panels. Shading a small portion of a panel can dramatically reduce the amount of electricity generated by the entire system.
Question 3: Can make money, is that real?
Quick Reply: What you heard is completely true. With a solar system on your roof, you can save 100% of your family’s monthly electricity bill, and even leave excess electricity to the utility company to receive a payment. monthly payment with the purchase price regulated by the State, the current purchase price of solar power is 1,943 VND / kWh.
Question 4: Investment in solar power systems for households is beneficial?
Quick Reply: Solar PV is a very beneficial investment in all aspects. Not only brings economic benefits to households and businesses, but this is also a clean energy source that helps your family reduce the amount of CO2 emitted into the environment, which is the biggest benefit.
Question 5: Which direction and angle would be optimal for panels?
Quick Reply: The best direction is directly facing the sun, the optimal angle, according to experts, is equal to the latitude at the location of the panel. In practice, we need to carefully examine the installation location to come up with the best solution.
Question 6: How long can photovoltaic panels last?
Quick Reply: The solar cell is the longest lasting component in the system. Committed uptime is usually over 20 years, but do not think that it will fail every 20 years, but it will only decrease in performance compared to the beginning. For the panels to always work well, we need to clean at least 1 time per month.
