5 solutions to improve the efficiency of rooftop solar power investment in 2023
Rooftop solar power is an effective renewable energy solution and is becoming increasingly popular in Vietnam. However, to improve the efficiency of rooftop solar power investment, appropriate solutions are needed.
Choose a reputable solar power consulting and construction unit
This is the most important solution to ensure the effectiveness of rooftop solar power investment. A reputable consulting and construction unit will help you choose a solar power system that suits your needs, climate conditions, terrain and roof area.
And some important criteria for choosing a solar power consulting and construction unit:
- Product quality
Before deciding which unit to choose, check the solar power projects that unit has implemented, reviews from customers, and make sure that the unit meets your needs and desires. At the same time, please refer and compare prices to make the most reasonable investment decision.
Choose a suitable solar power system
To choose the appropriate solar power system, you need to determine the following factors:
- Electricity demand: You need to determine the monthly electricity demand of your family or business. This will help you choose a solar power system with appropriate capacity, ensuring it meets your electricity needs.
- Climatic conditions: Vietnam is a country with a tropical monsoon climate, with abundant solar radiation. However, you also need to survey the area where the solar power system will be installed to check weather factors, lighting conditions, etc. If the installation area is cloudy or foggy, you need to choose the system. Solar power has higher efficiency.
- Terrain and roof area: You need to determine the terrain and roof area to choose the appropriate size solar power system. If the roof area is limited, you need to choose a solar power system with a small capacity.
- Type of solar power system: There are two common types of solar power systems: grid-connected solar power systems and independent solar power systems . The grid-connected solar power system will help you use solar power and national grid power. An independent solar power system will help you use solar power in case of a national grid power outage.
- Price: You need to consider the cost of the solar power system to choose a system with a price that suits your budget.
