As solar prices continue to decline, utility solar PV plays a key role in the global energy transition, supporting large-scale renewable energy adoption. Residential solar PV refers to home solar power systems that generate electricity using photovoltaic (PV) panels.
Residential solar photovoltaic (PV) installations have boomed in China over recent years. However, knowledge about the economic performance of residential PV investments is still limited. Therefore, this study attempts to make a complete economic assessment of residential PV systems at the county-level.
As the initial cost of PV investments keeps declining rapidly, however, residential PV installations began to speed up gradually. The newly installed capacity of residential PV systems in China in 2019 is 4.2 GW p, which is just following the annual addition to solar PV capacity of the U.S., India, Japan, Vietnam, or Spain (REN21, 2020).
This will break severely, the base supporting the market of residential PV installations in 2021. Thirdly, the areas with good performance of residential PV investments are inconsistent with those with high solar radiation. The areas in Guangdong and Hainan do not have high solar radiation.
They are mainly located in North China, northeast China, and South China. Table 6. IRR and PBP projected for residential PV systems without subsidies and with residential electricity prices at the first tier in China in 2021 (Unit: area). All the areas have a PBP not longer than 24 years.
Wang et al. (2021) identified the distributed PV development at the city level in China, considering the solar irradiation and available land area. They pointed out that residential land occupied one-third of the potential PV land, and has a higher potential/demand ratio due to its lower power demand.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
