Solar Water Heaters Worldwide - Market Development
Overview
The use of solar energy to generate heat is a well-established technology that has been used for decades. However, Solar Water Heaters are more frequently used in some regions of the world than others.
Country Examples: Latin America
Main article: Solar Water Heating in Latin America
Country Examples: Asia
China
In absolute numbers, China is by far the largest national market: 40.3 million MWth were installed in 2011. Between 2001 and 2011, the market grew on average annually by 21.5%.[1]

India
Thailand
Country Examples: Africa
MENA region
Tunisia
The use of solar energy for thermal purposes is widespread in Tunisia and can be regarded as a success story. Since its launch in 2005, the ANME program “PROSOL THERMIQUE”, meant to promote the installation of solar water heaters, has led to an installed capacity of 816,000 m2 in 2015.
West Africa: ECOWAS
In 2012, the ECOWAS member States adopted the ECOWAS Renewable Energy Policy (EREP), with the target to equip around 50 per cent of all health centres, as well as 25 per cent of all hotels and agrofood industry facilities with hot water requirements with solar thermal systems by 2030.

| Country Report - Burkina Faso |
The solar thermal system market for the production of hot water in Burkina Faso is still nascent, although installations from the 1980s have been identified. So far, there are neither studies to document the state of the solar thermal market nor all thermal installations in Burkina Faso |
Local production is the main SWH provider in Burkina Faso. APEES (Association for the Promotion and Operation of Solar Energy) operating between 1994 to 2000 in the city of Bobo-Dioulasso |
0,7 m2 with 56L: 100,000 FCFA (152 EUR) 1,4 m2 with 100L: 225,000 FCFA (343 EUR) 2m2 with 100L: 525,000 FCFA (800 EUR)

| Country Report - Cape Verde |
Solar thermal energy is mostly used in hot water service of hotels, residential accommodation, boarding rooms and hostels, and a few private homes. Total capacity installed as of 2013 is estimated to be about 1380 kWth. |
In Cape Verde there is no local production of SWH |
Price found in the market is around 700 € to 850 € per square meter, all included (storage tank, pipes, valves, installation, etc.). The most common type of imported solar collector is the indirect thermosiphon system of flat plate ranging from 150 litres to 300 litres; normally the 150 litres units have 2 m2 of area. Direct type collector of 160 litres capacity is also imported. |
| Country Report - Ghana |
Capacity installed of SWH was 725.9 kWth as of July, 2015. 435 kWth in Hotels, 60 kWth domestic, 227 kWth industrial and 3 kWth in institutions. |
n/a |
The cost of solar water heating systems and components in Ghana varies depending on the country of origin and the company that manufactured it.
|
| Country Report - Nigeria |
There are no official data on the installed capacity of solar thermal systems in Nigeria. However, installed solar water heating collector area is estimated to be about a very low level of only 200 m2 (140 KWth). Most of the SWH are in homes. |
n/a |
A typical 150 litre system with evacuated tubes cost about N100,000 (€444) with an installation cost of about N30,000 (€133). |
| Country Report - Senegal |
Installed SWH capacity is estimated at 1611 m2 or 1127.7 kWth in 2015. 70% with the city of Dakar. In recent years, the sale of SWH has multiplied. |
All individual SWH currently sold in Senegal are of foreign origin. The comfort standards of the middle class have created a demand. |
Costs range from FCFA 350,000 (~ 540 €) to 1,250,000 CFA (~ 1920 €) depending on the type of SWH. The connection cost ranges from 75,000 CFA (~ € 115) to 125,000 CFA francs (~ 190 €). |
