SOLAR ENERGY


THAILAND

The Thai Government has for many years recognised the need to diversify its energy supplies and the energy Master Plan prepared during the 1980’s has been developed under successive five-year plans. The New and Renewable Energy Programme under the National Energy Policy Office’s (NEPO) Energy Conservation Promotion Programme states that renewable energy is expected to play a major role in the future.

Owing to the country’s location near the equator, the consequent good level of insolation is utilised for both solar thermal and solar PV installations.

Government agencies are involved in the PV sector and those with substantial PV installations are: the Department of Energy Development and Promotion (DEDP), Provincial Electricity Authority (PEA), the Telephone Organisation of Thailand (TOT), the Public Work Department (PWD), the Ministry of Education and the Ministry of Public Health.

The Electricity Generating Authority of Thailand (EGAT) has over the years played a central role in the development of solar energy systems, although the first PV applications were installed in 1976 by the Ministry of Public Health and the Medical Volunteers Foundation at rural health stations for communications equipment.

By end-1999 about 5 MWp of PV modules had been installed in the country, of which TOT had 1 MWp installed for use in microwave repeaters, PWD had 1.5 MWp for water pumping systems (both for domestic and irrigation) and the Ministry of Education had some 20 kWp installed in remote schools.

EGAT has also developed stand-alone projects, grid-connected systems and hybrid hydro-PV, diesel-PV and wind-PV systems. In recent years EGAT has collaborated with NEPO to implement a rooftop PV project. Following the successful installation of PV panels on 10 households, 100 more were selected and the programme has now been expanded to include government buildings.

Currently some 50 000 m2 of flat-plate collectors have been installed on commercial buildings, hospitals and private residences and solar thermal capacity is expanding at a rate of some 3 000 – 3 500 m2 of solar water heaters per year.

EGAT is supporting an R&D programme for concentrated solar collector and storage systems and NEPO is preparing a solar hot water programme for hotels, resorts and hospitals.
