The capacity and cost of installing solar power for households depends on many factors, specifically:

  • Family power consumption: Solar power system capacity needs to be designed to suit the family’s power consumption. If your family has high power consumption, you need to install a system with a larger capacity.
  • Installation location: The solar power system installation location affects the system’s performance. Systems installed in locations with lots of sunlight will have higher performance.
  • Type of solar panel: The type of solar panel also affects the cost of installing the system. High-performance solar panels often cost more.

Installed capacity of solar power for households

Typically, the installed capacity of solar power for households ranges from 1 kWp to 10 kWp. The larger the installed capacity, the higher the cost.

Payback time for investment in solar power installation

The payback period for investment in installing solar power for households usually ranges from 3 to 5 years.

  • Family power consumption: Families with high power consumption have a shorter investment payback period.
  • Electricity price : If electricity prices increase, the investment payback period will be shorter.
  • Policy to support solar power installation : Policy to support solar power installation will help reduce investment costs and shorten payback time.

The capacity and cost of installing solar power for households depends on many factors. Families need to consider these factors to choose a solar power system that suits their needs and financial ability.

Factors that determine the cost of solar power installation

The cost of installing a solar power system is influenced by many different factors. Below are some main factors that determine the cost of solar power installation:

  • System capacity: The larger the system capacity, the higher the cost.
  • Type of solar panel: High-performance solar panels often have a higher price.
  • Type of inverter: Inverters with large capacity and many functions often have a higher price.
  • Cost of additional materials: Cost of additional materials includes electrical wires, racks, electrical cabinets, etc.
  • Solar power construction cost: Construction cost depends on installation location, complexity of the system…

System capacity

System capacity is the biggest determining factor in the cost of solar power installation. System capacity is calculated in kWp (kilowatt-peak). One kWp is the amount of power the system can generate under ideal conditions, with a sunlight intensity of 1,000 W/m2.

A home’s power consumption is an important factor in determining the required system capacity. Families with high power consumption need to install systems with larger capacity.

Type of solar panel

Solar panels are the main component of a solar power system. There are many different types of solar panels on the market, with different performance levels and prices.

High-performance solar panels often cost more. However, high-performance solar panels will generate more electricity, helping to reduce investment costs and shorten payback time.

Inverter type

An inverter is a device that converts electricity from direct current (DC) from solar panels to alternating current (AC) for home use.

There are many different types of inverters on the market, with different power levels and functions. Inverters with large capacity and many functions often have a higher price.

Additional material costs

Additional material costs include electrical wires, racks, electrical cabinets, etc.

Electrical wires are an important component to connect devices in a solar power system. Brackets are devices to fix solar panels on the roof. Electrical cabinets are devices to protect solar power systems.

Cost of construction

Construction costs depend on installation location, complexity of the system,…

Locations where the system is installed with a lot of shade will cost more to install solar panels. Solar power systems with many complex equipment will cost more to construct.

Benefits of installing solar power for households

Installing solar power for households brings many benefits, including:

  • Save electricity costs : Solar power systems can meet part or all of the family’s electricity needs, helping to save electricity costs.
  • Environmentally friendly: Solar power is a clean energy source that does not pollute the environment.
  • Added value: Solar power systems can increase the value of a family’s assets.
