In this regard, successful experiences of rural electrification using off-grid PV mini-grid systems have been documented, for example, in India, Kenya, Tanzania, Nepal, and Namibia (Come-Zebra et al., 2021), (Pedersen et al., 2021).
Although some progress has been made in recent years, ensuring universal access to electricity remains a major challenge in many countries in sub-Saharan Africa, particularly in rural areas. In light of this challenge, solar photovoltaic (PV) mini-grid systems have emerged as a promising solution for off-grid electrification.
As a result, with the high solar irradiation in December, the inverters’ AC power out exceeds the load and battery storage capacity early in the day, around 11:00, before the mid-day peak load, and active power clipping occurs. This phenomenon was also confirmed during our field visits to the MG plant in December 2021.
Sharma and Chandel (2013) investigated the performance of a 190 kWp grid-tied PV plant in northern India; and found that the plant produced 98.8% of the estimated annual energy yield. The authors reported the annual mean performance ratio and overall system efficiency of the plant to be 74% and 8.3%, respectively.
Research approach Research on rural electrification through PV mini-grids involves analyzing the interactions and relationships between a wide range of variables, from the technical and operational elements of the mini-grid to the economic and institutional characteristics of customers (Hartvigsson et al., 2021).
These results confirm that only 53.4% of the potential solar energy available at the PV array's surface (Y R) is harvested by the inverter (Y A).
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.
