How much does a 4 kW grid-tied system cost to fully install?

4kW (kilowatt) systems are often quoted for installation with prices ranging from 55 to 65 million VND to fully install from A-Z from materials to transportation and installation costs.

However, these price estimates will depend on a number of factors depending on the location and type of frame and roof installed.

The systems that we have installed are selected from high efficiency panels, famous brands, Mono types, and SoFar inverters – one of the 5 most popular inverter brands in solar installations in Vietnam. market in our country, together with a team of professional technicians create a system with perfect operability

Area to be installed for solar panel system 4 KW

Installing the battery system does not have to be a hassle. There are several things you can do to ensure that you get the most out of your 4kW solar panel system. This includes where to place the solar panels (away from any shade). You need to make sure that your home is suitable for the installation, watch the direction of the sun to measure the direction of the panels to get the best energy. The power output of a system is proportional to the energy it receives from the sun. If the panels are shaded, the energy they can convert into electricity is limited.

System output power 4kW

There are several factors that affect the actual power output of a 4kW system. Including:

Geolocation of the system and expected daily/annual solar irradiance there

Mounting direction and tilt angle of solar panel array

Is it affected by the shade?

Actual operating conditions of the board & inverter (e.g. temperature)

Depending on the location of the system, it will receive different amounts of solar irradiation each day and each year. The amount of sunlight hitting the solar system Solar panels directly affect the system's output. An installation can expect to receive an annual average of around 4-5 hours of 'peak sun' per day, i.e. 1 KW a day will generate 4-5 KWh of electricity.

Benefits of installing a 4kW solar battery system:

Wondering whether to invest in a solar energy system? It is true that installing a 4KW system means a significant investment, but this will ensure that you will produce your own and clean energy, and will also save money in the future. As with any major investment, we should also think about the long-term perspectives.

As more people switch to green energy, economies of scale are leading to lower prices in respective technologies. In the next few years, solar panels will be cheaper, and more efficient.
