New technique to predict solar inverter temperature
An international research team has developed a novel approach for predicting inverter temperature through symbolic regression based on particle swarm optimization.
New database for PV module fault detection
Scientists in Colombia have created a 10-year open dataset for PV panel fault detection. Data was acquired using an electronic load system, oscilloscope, and thermographic camera in outdoor environmental conditions.
Colombia deploys 1.6 GW of solar in 2024
Colombia installed 1.6 GW of solar in 2024, bringing its total capacity to 1.87 GW by year-end. Industry group Ser Colombia says 33 utility-scale projects accounting for 1,410 MW were added to the grid.
Colombia adds 104 MW of new solar in Q3
Colombia installed 104 MW of new solar in the third quarter, raising its cumulative PV capacity to 1.34 GW by the end of September 2024.
Colombia creates energy community benefiting 2,000 low-income families
As part of its Sustainable Energy Homes Project initiative, the Ministry of Mines and Energy has announced plans to install PV systems next year in two neighborhoods in the city of Cali that will allow a reduction of up to 100% of electricity bills for local residents. The government is also implementing sustainable electric mobility solutions for five educational institutions in the city.
144 MW La Unión solar plant inaugurated in Colombia
Spanish company Zelestra officially connected the plant to the electrical grid last June. Colombian President Gustavo Petro, along with other authorities, participated in the ceremony.
Enel completes 486.7 MW solar park in Colombia
Enel has finished installing PV modules at a 486.7 MW solar park in Colombia. Once fully operational, it will be the largest PV project in the country.
Cellphone-linked portable device for real-time solar module characterization
Scientists in Colombia have conceived a new portable electronic device for on-site measurements of the I-V and P-V curves of photovoltaic panels. The novel system considers solar radiation, ambient temperature, electric current, and voltage signals from a PV panel via a cellphone through a mobile application.
Colombia: 922.8 MW of PV projects under construction
According to the country’s Mining and Energy Planning Unit, of all the projects currently operating in Colombia that it is aware of, 10,672 MW are photovoltaic, followed by 8,452 MW of wind, 1,973.9 MW hydraulic, 672 MW thermal and 42.7 MW biomass.
