The potential of PV installations in SIDS - an example in the island of Barbados

Purpose – This paper reviews the current status of photovoltaics on the island of Barbados, including experiences to date, and discusses the future directions with a view to sharing the experience gained with other small island developing states (SIDS). Design/methodology/approach – As with many SIDS Barbados is heavily reliant on fossil fuels to meet their electricity generation needs (currently 98 per cent of total electricity generation). The paper outlines how solar PV sits within the existing energy structure for the island of Barbados and reflects on the experience gained from the success of its solar thermal hot water heating industry. Findings – This paper estimates the installed capacity of photovoltaic solar systems on Barbados was estimated to be around 200?kWp in 2010 (0.18 per cent of the average electricity demand, not including the load factor of the PV systems). Practical implications – With an average daily solar radiation of 5.7?kWh/m2, the potential of the resource is clear to see, with solar PV being capable of substantially contributing to the island's energy mix and saving valuable foreign exchange. Originality/value – Concerning the increasing role of solar PV in the energy mix for Barbados, substantial barriers are still observed. The paper has tried to identify these barriers and has provided a detailed overview of the energy sector and solar thermal success in Barbados.
