Ghana’s solar energy market is expected to experience significant growth over the next five years, with installed capacity projected to increase from approximately 0.3 gigawatts (GW) in 2026 to 1.48GW by 2031, according to a new outlook by Mordor Intelligence. The forecast points to sustained expansion driven by declining solar photovoltaic (PV) costs, expanding electrification efforts, and supportive policy measures aimed at accelerating renewable energy integration into the national grid. This anticipated growth rate positions solar power as one of the fastest-growing segments within Ghana’s renewable energy sector, strengthening its contribution to diversifying the country’s power generation mix.
The report indicates that the photovoltaic segment dominates Ghana’s solar market, accounting for virtually all installed capacity. A compound annual growth rate of around 37 percent is projected during the forecast period, supported by both utility-scale projects and distributed generation systems. Large-scale solar installations currently represent more than three-quarters of operational capacity, but the commercial and industrial segment is gaining momentum as businesses invest in embedded solar systems to manage tariff volatility and concerns about grid reliability. Rising corporate demand for energy security, particularly among mining companies, telecom operators, and manufacturers, is reshaping energy consumption patterns.
Off-grid and mini-grid solar solutions are also expected to expand, especially in underserved northern communities and island settlements. Rural electrification policies and donor-supported financing frameworks are helping drive decentralized solar deployment as a cost-effective alternative to grid extension. However, the report emphasizes that policy and regulatory factors will remain critical to sustaining investor confidence. While fiscal incentives such as tax exemptions on renewable energy equipment have lowered investment barriers, challenges including grid absorption constraints and a moratorium on new power purchase agreements could slow near-term growth if not resolved.
Currency depreciation and Ghana’s reliance on imported photovoltaic modules present additional cost pressures. Although global module prices have declined, exchange rate volatility continues to affect project economics, making import exposure a key concern for developers. Geographically, major projects are concentrated in Greater Accra, Ashanti, and Bono regions, with the Bui enclave and coastal zones identified as strategic renewable corridors capable of anchoring future expansion.
The market remains moderately fragmented, attracting a mix of local energy firms, state-affiliated entities, and international developers pursuing public-private partnerships. Innovative financing approaches, including solar-as-a-service models, are also emerging to help small and medium-sized enterprises adopt solar solutions without significant upfront capital investment. While Ghana’s long-term energy transition goals position solar power as central to achieving energy security and climate targets, experts stress that continued growth will depend on coordinated infrastructure development, streamlined permitting processes, and strengthened financial mechanisms to reduce risk for private investors.
