CURRENT POWER SYSTEM As mentioned previously, the current power system of the Republic of Palau is widely dominated by conventional fossil fuel generation. The calibration model developed has shown that currently, renewable energy generation represents only 4.03% of the total share of Palau’s power sector.
As there is no battery storage system currently present in Palau, the panels can only generate throughout the day when the sun is available, and no electricity can be stored for later use. Furthermore, the figure also confirms that Palau’s current power system is widely dominated by fossil fuel generation.
The results of the optimisation show that Palau’s current power system is dominated by diesel generation, with renewable energy only taking a small share (just 4%). With more deployment, however, the share taken by renewables could potentially increase to more than 92%. This corresponds to the lowest average system LCOE.
For this study, it was assumed that the total diesel generation capacity of Palau’s current power system is 20 MW (the four largest generators present in Palau). Table 2 shows in more detail the generation capacity for each power plant currently present in the country. Source: PPUC and PEA data (n.d.).
Source: PPUC and PEA data (n.d.). Together with a large amount of diesel generation, Palau also has some installed solar PV capacity. Indeed, the country’s current renewable energy capacity includes a total of 2.5 MW of utility-scale solar PV systems (see Table 3).

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.
