Prix ​​du système d'alimentation solaire pour la maison 5KW

If you are looking to invest in solar, one of your first questions is probably how much will they cost? Pricing depends on the size of the system you want to install, the type of equipment you choose, and where you live, but consider the price for a 5 kilowatt (kW) system because a 5KW Off Grid Solar Power System is for appliances household appliances, using clean energy contributes to environmental protection, helping to save daily electricity consumption. This is the most common size of solar power installed in households today.

Working principle:

– These 10 panels combine together to form a complete solar power system mounted on the roof, After installation is completed, they will absorb sunlight to generate direct current (DC) connected to PV . junction box

– PV combiner box amplifies the maximum power output and stored to the grid-tied inverter, this inverter will play the role of converting direct current (DC) to alternating current.

– Turn on the system and start using electricity from the system right away. Your home electrical appliances will prioritize using electricity from the sun first, if there is a shortage, they will continue from the grid, if not used up, the excess electricity will be connected to the grid, at the end of the month you will be paid by the state. pay back this balance.

How much will a 5kW solar power system cost in 2022?

Solar panels in general have experienced a sharp decline in prices in recent years, as the competition among installers has reduced the price of solar PV installations significantly, now is the favorable time. to help you decide on the right installation.

These 5kW systems are among the most popular system sizes, as the ideal price/power ratio of the system is extremely beneficial.

Up to the present time, the average cost to install solar power in our country is about 15 to 20 million on average per 1KW. That means the total cost for a 5,000 watt system will range from 75 to 100 million. Why this price swings exists, depends on a number of factors, so these numbers are just meant to be a starting point:

Where to install: inner city or suburban.

Type of installation: Attic or mounted on the frame system, the height of the frame…

Output of a 5KW solar power system:

The generated capacity of a 5kW system becomes a system sufficient to meet the needs of an average household in our country. The amount of electricity generated depends on many factors, including the orientation and angle of the roof. What matters most is how sunny it is where you live – for example, a 5 kW system in HCMC will be different than in Binh Thuan because each area has different amounts of sunshine and radiation. But on average at least 1 system will receive 4 hours of sunshine per day, so a 5KW system will collect at least 20 KW of electricity per day, which will produce about 4,500 kWh of electricity per year.

Factors affecting the output efficiency of the system:

While you can get a rough estimate of the power output of a 5kW solar panel system, you should keep in mind that there are a number of factors that will inevitably affect the efficiency of a panel. For example:

The geographical location of the installation: this affects the daily solar radiation and determines the potential output of the system.

The panels must be placed in the place that is most exposed to sunlight. On the other hand, shade can significantly reduce power output.

The orientation and tilt angle of the 5kW solar array is also important to get the most sunlight

The performance and features of the individual components are also affected, as not all brands offer the same energy efficiency. Here we discuss the main components that make up the system, namely the panel and the inverter, the better they are, the higher the efficiency will be: Mono batteries will be more efficient than Poly, choose a reputable inverter

Also keep an eye on the system regularly so it won't be obstructed by foliage or dirt that can interfere with sunlight exposure, if you see a lot of dirt, get them charged.

Space required to install 1 5KW system:

The mounting space of a system will depend on the mounting space of the panels, more specifically the number of panels. The 5kW system is made up of 20 panels, assuming you use 250W panels. The dimensions of each slab will be approximately 1.6 m x 1 m, so at least 32 square meters of roof space is required to accommodate the space needs of this system.

Advantages of 5 KW solar power system:

Solar panels are guaranteed to last at least 25 years with an estimated lifespan of 30 years.

A 5kW system will add value to the home it is installed on.

Supplying electricity for home use to save monthly electricity consumption of household electrical appliances

The installation is easy and safe, without worrying about electric shock or fire if only DC equipment is used

Using clean, inexhaustible green energy, contributing to environmental protection. Solar power systems bring great benefits to reducing electricity costs by using completely free energy from sunlight.

Fully automatic operation, long system life with long profit time.
