Abstract	Smallholder farmers frequently sell agricultural commodities immediately after harvest because processing, cooling, drying, milling, and other postharvest services are unavailable or dependent on unreliable and costly energy. This weakens farmers' ability to preserve quality, extend marketing periods, reduce losses, and retain value before products move further along agrifood chains. Solar-powered processing provides a potentially important response by locating renewable-energy-based drying, refrigeration, milling, chilling, and first-stage transformation closer to production areas. This study develops a methodological framework for evaluating when solar-powered farm-gate processing can generate meaningful value addition rather than functioning merely as a substitute for conventional energy. Because authenticated processing records, energy-meter observations, market prices, and farm-level profitability data were not supplied, the quantitative component is explicitly simulation based. A synthetic portfolio of 160 smallholder processing profiles is evaluated across perishable horticulture, dairy handling, cereal processing, and high-moisture specialty crops. A Solar Farm-Gate Processing Readiness Index is developed from technology–product fit, energy reliability, processing efficiency, quality assurance, market linkage, equipment utilization, and maintenance capacity. A complementary Farm-Gate Value Retention Score evaluates the extent to which farmers preserve product quality, reduce forced immediate sale, capture processing margins, and improve marketing flexibility. Simulated analysis shows mean value-retention performance increasing from 55.0 under immediate unprocessed sale to 80.0 under appropriately configured solar-enabled processing. The largest benefits occur where energy access is a genuine processing constraint and where processed products have identifiable markets, quality standards, and sufficient throughput. The study also identifies limitations involving high capital costs, seasonal underutilization, inadequate maintenance, food-safety requirements, weak market demand, and unequal access to shared processing assets. Solar-powered value addition should therefore be understood as an integrated agribusiness capability combining renewable energy, processing technology, quality management, market access, and viable ownership models.
