Eternal Inverter 
Comparison of basic concepts:
Solar air conditioner: Solar air conditioner uses solar photovoltaic panels to convert sunlight into electric energy, which directly drives the air conditioning operation. It relies on renewable energy (solar energy) for power supply, hardly needs the support of external power grid, reduces electricity expenses and is environmentally friendly.
Traditional air-conditioner: Traditional air-conditioner is driven by grid power, and uses compressors and other components for cooling or heating. Its energy consumption is high, especially in summer or winter when it runs under high load, so it needs to pay higher electricity bill.
Energy saving advantages:
Energy-saving advantages of solar air conditioners：
Using solar energy to drive: solar air conditioners use solar photovoltaic panels to convert solar energy into electricity and drive air conditioners to operate, almost independently of the power grid. Solar energy is free, and the long-term operating cost is significantly lower than that of traditional air conditioners.
Reduce electricity expenses: In sunny conditions, solar air conditioners can be completely powered by solar energy, saving a lot of electricity charges in the grid, especially when air conditioners need to be used for a long time in summer and winter.
Low-carbon environmental protection: By using renewable energy, the operation of solar air conditioners hardly produces carbon emissions, thus avoiding the environmental impact caused by the high energy consumption of traditional air conditioners.
Energy-saving disadvantages of traditional air conditioners：
High energy consumption: Traditional air conditioners rely on grid power, which leads to extremely high energy consumption in summer and winter when the load is high, resulting in a substantial increase in electricity bills.
Environmental burden: Traditional air conditioners usually consume a lot of electricity, and the generation of electricity mainly depends on fossil fuels, resulting in greenhouse gas emissions and a greater burden on the environment.
Energy waste: Even at low temperature or without full refrigeration, traditional air conditioners continue to consume electricity, resulting in energy waste.
Economic benefits:
Solar air conditioner:
Reduce electricity expenses: Solar air conditioners are powered by solar energy and can operate independently of the power grid most of the time, greatly reducing long-term electricity expenses. Especially in sunny areas, the electricity bill is almost zero.
Low maintenance cost: The maintenance cost of solar air conditioners is relatively low. The service life of photovoltaic systems is usually 20-25 years, and the maintenance cycle is long, and the system components (such as solar panels) are usually durable.
Long-term cost saving: Although the initial investment is high, the long-term operating cost is low. With the rising energy price, the use of solar air conditioners can reduce the dependence on grid power and achieve significant cost savings.
Traditional air conditioner:
Higher electricity expense: Traditional air conditioners rely on the power grid for power supply, especially when they are used with high load in summer or winter, the electricity expense is higher. The fluctuation of electricity price may lead to the increase of long-term operating cost.
Short service life: The service life of traditional air conditioners is generally 10-15 years, and parts need to be repaired and replaced regularly during use, which increases the maintenance cost.
Low energy efficiency: The traditional air conditioner has low energy efficiency, especially when it does not need full power operation, it still consumes a lot of electricity, resulting in energy waste and increased cost.
Applicable scenarios:
Applicable scenarios of solar air conditioners:
Remote areas or areas with unstable power grids
Enterprises that need to reduce long-term operating costs
Areas rich in solar energy resources
Buildings or projects with high demand for environmental protection.
Household (energy-saving)
Applicable scenarios of traditional air conditioners:
Cities and power stability areas
Short term or seasonal use
High-budget limited users
Areas requiring efficient refrigeration
Mild climate area
Maintenance and life:
Solar air conditioner:
Maintenance requirements:
Cleaning of photovoltaic modules: The operation of solar air conditioners depends on solar photovoltaic modules, so it is necessary to clean the dust, fallen leaves and other sundries on the surface of photovoltaic panels regularly to ensure the power generation efficiency of photovoltaic panels.
Battery maintenance: If the solar air conditioning system is equipped with an energy storage battery, it is necessary to check the charging and discharging state of the battery regularly to avoid excessive discharge or long-term idle.
Inverter inspection: As an important part of solar air conditioning system, the inverter needs to regularly check its working state, check whether the line connection is loose and whether the cooling system is normal.
Maintenance of refrigeration/heating system: The core air conditioning part of solar air conditioner, similar to traditional air conditioner, needs to check the filter screen, condenser and compressor regularly.
Life span:
The life of photovoltaic modules is usually 20-25 years; The life of energy storage battery depends on the type, and the life of lithium battery is about 8-10 years. The life of inverter is usually 10-15 years; The service life of the air conditioner body is about 10-15 years.
Traditional air conditioner:
Maintenance requirements:
Cleaning of filter screen: the filter screen of traditional air conditioner is easy to accumulate dust, so it needs to be cleaned regularly to ensure air circulation and cooling/heating efficiency.
Maintenance of condenser and evaporator: Clean and check the condenser and evaporator regularly to avoid system efficiency decline or pipeline blockage.
Refrigerant replacement: With the increase of service time, the refrigerant may need to be replenished or replaced to maintain the cooling performance.
Inspection of compressor and electrical parts: compressor, motor and electrical circuit should be inspected regularly to ensure safe and stable operation.
Life span:
The life of ordinary household air conditioners is usually 10-15 years, and the specific life depends on the frequency of use and maintenance.
The service life of commercial air conditioners can be extended to 15-20 years, but more frequent professional maintenance is needed.
Solar air conditioner is gradually becoming a powerful substitute for traditional air conditioning because of its characteristics of energy saving, high efficiency, environmental protection and low carbon. Today, with the rising energy costs and increasing awareness of environmental protection, solar air conditioner can not only significantly reduce energy consumption and carbon emissions, but also help families and enterprises better meet the challenges of energy transformation. Although the initial investment is high, its long-term operating cost advantage makes it a wise choice to pursue sustainable development and reduce operating expenses.
