Promotion of solar water heating systems

Barbados

The Ministry of Finance of Barbados
Solar Dynamics, SunPower, and AquaSol

The promotion of solar water heating systems in Barbados resulted from concessions granted by the Ministry of Finance, which enabled manufacturers to import materials duty-free, and provide consumers with partial or full tax deductions forthe cost of the heaters.

The simple thermosyphon solar water heater consists of a solar collector or solar panel, a tank and the interconnecting plumbing that is normally insulated. The recommended size of a solar collector for a family with four members is four m 2 with a 300-litre tank capacity. Such a system currently retails for about $US2000. Heating water with imported fossil fuels or with electricity generated with fossil fuels causes emissions of greenhouse gases to increase while depleting foreign ex-change reserves. Using solar water heating is good for the environment
as well as the national economy. The industry minimizes the loss of foreign reserves while encouraging entrepreneurship, which in turn creates employment opportunities. Solar water heating companies include Solar Dynamics,SunPower, and AquaSol.

• Energy resources (Chapter VII of the Barbados Programme of Action)
• National institutions and administrative capacity (Chapter X of the BPoA)

• The solar water heating industry saves Barbados about $US 6.5 million per year in imported fuel.
• Inspired by these incentives, the entrepreneurs took the industry forward. Currently, about 32,000 solar water heaters are installed in homes, commercial businesses and hotels in Barbados.
• For the consumers, the 32,000 solar water heaters save about $US 16 million, under the assumption that they would have used electricity at normal rates to heat the water.
• Over 50 hotels now use the renewable energy method. The large-scale integrated designs cover the hotel roof with solar collectors, measuring about 300 m 2 , and have large 27tanks of up to 25,000 liters, which allow the heat from the central air conditioning system to be used to preheat the water.
• One company is now assisting in the installation of solar photovoltaic
panels on the roof of Government headquarters for emergency lighting as well as at a fishing complex for powering the ice machines for the preservation of fish.
• Two of the companies are expanding to other Caribbean islands, one in Saint Lucia and the other in Trinidad.
• The entrepreneurs acquired a considerable amount of expertise, especially in the areas of manufacturing and installing large solar water heaters.

The promotion of solar water heating systems demonstrates Barbados’ ability to achieve sustainable development using renewable energies, namely solar power. With the necessary technology and political will, solar energy can replace fossil fuel technologies. This is not only more economically and environmentally beneficial, but it also shows the willingness of Small Island States to participate in the international efforts to decrease GHG emissions.
