The first record about solar thermal energy use in Colombia dates back to the 50s with the installation of solar heaters in the banana workers homes located in Santa Marta. The heaters still exist, but they do not work.
In the 60s Israeli solar heaters were installed in some universities in Santander and Bogota.
In the 80s in Medellin, Manizales, some neighborhoods of Bogota and later in the Atlantic coast, solar heaters began massively used; forcing regulation of their use through INCOTEC (Colombian Institute of Technical Standards).
In March 1993 the NTC 3507 was enacted, referring to domestic hot water systems powered by solar energy installations.
In mid 90s, with the support of foundations like Gaviotas, the use of solar heaters spread to hospitals and community centers.
Until 1996, 48.901 m2 of solar thermal systems had installed, mainly in neighborhoods of Medellin and Bogota with Central Bank funding.
All this development stopped short with the introduction of a cheaper energy source, natural gas, which displaced the market of this nascent industry from then until now.
Most systems work well but some users had other expectations of them, which has hinted that the demand exceeds the capacity of the equipments.
Currently, the solar industry remains depressed in Colombia waiting for a new energy crisis.
The only program that tried timidly incorporating solar thermal energy began in 2009 in San Andrés as part of the implementation of solar energy in buildings, to evaluate their behavior in a residential installation.
State action should be directed towards the solar thermal energy development:
– To diversify the national energy matrix and give flexibility to the power supply system
– To reduce the environmental impact of fossil fuels and the reserves depletion
– To provide power supply in remote and isolated áreas
The national energy policy should move towards a gradual increase of supply based on solar thermal energy, developing strategies and setting ambitious and achievable goals, consistent with a gases emissions reducing policy.
The Law URE (Rational Use of Energy) and 3683 Decree, have not been sufficient to promote this energy source, as evidenced results obtained from its promulgation.
