How much does the price of residential solar photovoltaic panels usually cost?

With the rising cost of energy and enhanced awareness of environmental protection, increasingly more families are beginning to consider the installation of solar photovoltaic systems in order to achieve the aim of self-consumption, energy saving, and emission reduction. Thus, "How much does the price of household solar photovoltaic panels usually cost?" It has become a burning topic for numerous consumers. In this article, I will give you a comprehensive answer to this question from the aspects of price composition, factors affecting the price, and return on investment.

The price range of the household photovoltaic systems

The price of household solar photovoltaic systems is not identical, typically as "yuan/watt" to calculate. Up to now, the typical installation price of household photovoltaic systems in the Chinese market is around 3-4 yuan/watt. If there is a plan to install a 5 kilowatt (KW) photovoltaic system in the household, the total price will be around 15,000 to 20,000 yuan, and the actual price will vary according to location, grid access mode and installation conditions.

In foreign markets (Europe and the U.S.), where labor is expensive and there is strict certification, a system of similar size can cost $1.5 to $2 / watt or more.

Photovoltaic price composition

The cost of residential solar photovoltaic panels is not merely the cost of the "board," a complete photovoltaic system usually comprises the following elements:

Photovoltaic modules (solar panels) : 30% to 40% of the total cost, general monocrystalline silicon, polysilicon etc.

Inverter: change direct current into alternating current, the "heart" of the system, occupying approximately 15% to 20%.

Bracket system: Utilized to support the panels, the cost will differ according to the structure of the roof.

Auxiliary materials like cables and distribution boxes: guarantee the security of power transmission.

Labour and installation charges: It may be more costly based on the region, particularly in rural areas.

Grid connection process and after-sales service charges: Installation companies can charge a one-time service charge.

How will the final cost be affected?

Installation capacity: The greater the capacity, the lower the cost per watt (scale effect).

Brand and model type: Foreign makes are more costly but offer improved performance.

Whether the energy storage system is needed: If it is integrated with lithium battery energy storage devices, such as wall-mounted batteries or liquid coolers, the cost will be much higher.

Roof conditions: The south sloping roof is simpler to install, the construction is simpler and the cost is lower.

Government subsidy policy: There are subsidies for finance or electricity subsidies in some places, which can effectively reduce the initial cost of investment.

Is it profitable to install a photovoltaic system?

Economically, the payback period of domestic photovoltaic is generally 5-8 years. With a 5KW system, you can get about 5000 degrees of electricity per year, and can save about 3000 yuan per year considering the self-use electricity price of 0.6 yuan/degree. If you have remaining electricity to send online, you can also enjoy a certain subsidy.

From the point of view of the environment, it can save about 4-5 tons of carbon dioxide emissions annually, and that is also conducive to air quality improvement and anti-climate change.

Purchase suggestions and warnings

Choose common manufacturers and installation teams to stay away from post-purchase concerns;

Be aware of component conversion efficiency and warranty period;

Get familiar with local grid access policy and subsidy policy;

Evaluate the structure and power demand, and reasonably decide on the capacity of the system;

If you consider the energy storage function, you may concentrate on the integration of mobile energy storage devices or wall-mounted batteries.

The price of home photovoltaic panels is generally about 3-4 yuan per watt, and installing a whole 5KW system requires 15,000 to 20,000 yuan. Even if the investment isn't small, in the future, it is really good from the economic point of view, as well as from the environment. With advances in technology and promotion by the policy, solar cells will be more and more popular in the future and become a new solution for ten thousands of households to use green energy.

If the installation is to be planned, it is recommended to find out the policy locally in advance, choose a competent service provider, and have scientific configuration according to the actual usage of electricity.
