Oak Ridge National Laboratory calculated that
Barbados saved 15,000 metric tons of carbon
emission from 35,000 Solar Hot Water Systems in
2002.
This corresponds to an average saving of:
428 kgCO2 per system per year
This estimate is in accordance with the US Department
of energy (25.4 metric tons of carbon per terajoule).

In 2009, with 50,000 Solar Hot Water Systems
installed, Barbados saved:
21,400 metric tons of CO2
This saving makes up more than 5.5% of all
carbon emissions in Barbados. (estimated 380,000
metric tons of CO2 emissions in 2009)

The more important factors responsible for Barbados’
success in solar hot water systems are:
Recognition of the potential importance of Solar
Water Heaters at the very highest levels of
Government
Development of the industry at a time of rapidly
rising electricity costs and awareness of energy costs.
14
13
Implementation of key fiscal incentives to lower
Solar Water Heater costs.
A small but timely Government purchase program
for housing development projects.
The combination of high electricity costs and
financial incentives made for very low payback periods
and little financial risk for the consumer.
Local companies that stand behind the product by
offering
performance
warranties,
specified
temperatures, and reliable after sales service.

The Barbados Solar Water Heating program is
unparalleled in the Caribbean. (USAID)
The Solar Water Heating program in Barbados is
perhaps the best known and successful of all
Renewable Energy Technology programs in the
Caribbean. (USAID)
The critical expertise to develop the solar water
heating concept into a marketable and functional
product was provided by James Husbands. (USAID)

A Special Innovation Award was given in 2006 as
part of the National Industrial Awards, which sought
to recognize “the single innovation that has had
the greatest impact on the landscape of Barbados
within the last 50 years”.
That innovation was considered to be solar
technology. BIDC.

The market is for 17,900,000 people in 4,565,000
households across the Caribbean.
Assumed Total Maximum Penetration between 10%
to 50% depending on the country. (Trinidad 25%)
Based on systems already installed, the potential
market calculated is 798,000 systems. Average

A Vision for the Bahamas
Set goal of 50,000 solar water heaters installed by
2015
Implement package of incentives and financing to
facilitate rapid adoption; explore mandate on new
construction and require conversion beyond 2015
Significant energy use and emissions reductions
possible
Powerful economic benefits1

SDL: Making the Vision a Reality
SDL uniquely positioned to help Bahamas and other SIDS achieve
widespread adoption of solar water heaters
Analyze costs/benefits of various packages of tax incentives, financing
structures, and ownership regimes—financial model already
operational
Coordinate with Govt, private sector, local NGOs
Seek multi-lateral and bi-lateral funding / credit support
Help secure and monetize carbon credits
Explore low cost sourcing, local manufacturing, ECA support for
imports, volume purchase discounts
Consumer educational campaign
Apply Bahamas experience to other SIDS
Replicate successful structures / policies / partnerships
Consider regional implications of SWH program (e.g., manufacturing,
technician pool, volume purchases, etc.)
