Seizing the sunshine: Barbados’ thriving solar water heater industry

This policy brief examines the successful adoption of solar water heaters (SWHs) in Barbados, where over 50,000 units have been installed. The success is attributed to a combination of early entrepreneurial 'champions', consistent government fiscal incentives (such as the Homeowner Tax Benefit and the Fiscal Incentives Act of 1974), and strategies to reduce consumer risk through performance guarantees and credit schemes. The document highlights that these incentives provided high value, costing the government a small fraction of revenue while saving consumers millions of dollars annually. It concludes that the Barbados experience can be replicated in other sun-rich countries with high fossil fuel imports, provided there is long-term regulatory certainty and local sensitivity in implementation.

• Barbados has achieved significant market penetration of solar water heaters (SWHs), with over 50,000 installations for a population of 200,000. These systems save over 100,000 MWh of energy annually and have saved consumers a cumulative total of US$137 million since the early 1970s.
• The Barbados government implemented several fiscal and regulatory measures to stimulate the SWH industry. The Fiscal Incentives Act of 1974 provided a tax exemption for raw materials (saving 20% of cost) and a 30% tax on electric water heaters. Additionally, the government mandated SWH installations for all new government housing developments starting in 1977.
• The Homeowner Tax Benefit was a critical driver of growth, making SWH installation costs tax-deductible up to BD$3,500 (US$1,750). This incentive led to a peak of over 2,800 installations per year in 1989. Although stopped in 1992 due to economic restructuring, it was reinstated in 1996.
• Government support for the SWH industry is considered high value. In 2002, tax incentives cost the government BD$1.1 million (US$550,000), representing 0.06% of government revenues, while consumers saved between US$11.5 and US$16 million annually.
• Consumer acceptance was achieved by addressing technical risks and financial barriers. Companies offered temperature guarantees to ensure product quality and worked with credit unions and distributors to provide three-year credit terms, matching the typical payback period of the units.
• The success of the SWH industry in Barbados was heavily dependent on 'champions' and aggressive marketing. James Husbands of Solar Dynamics is cited as a key driver who used diverse marketing strategies, such as targeting people in wooden houses and employees of households during installations.
• Attempts to replicate the Barbados model in St Lucia were initially slow despite high fuel costs. The document notes that the use of Barbadians to run the project in St Lucia lacked local sensitivity; success improved only after the company employed local people.
