Study shows Brazil’s floating solar potential – pv magazine International


Brazilian scientists have calculated the potential for floating photo voltaic era in Brazil, assuming that it’ll cowl only one% of the unreal water space. The outcomes present an put in potential of 43 GW for all of Brazil, with the state of Minas Gerais main with 6 GW, adopted by Bahia with 4.59 GW, and Sao Paulo with 3.87 GW.

Researchers on the Federal College of Rio de Janeiro have developed a mathematical mannequin to calculate the potential for floating photo voltaic era in Brazil, detailing the outcomes for every state.

The research solely considers the potential era of synthetic water our bodies, equivalent to hydroelectric vegetation and dams, and solely in 1% of their usable space. The group used the database of the Nationwide Water Company and QGIS software program to filter the unreal water our bodies, with a complete of 174,526, excluding these on indigenous lands.

The enter variables of the mannequin usually are not solely photo voltaic irradiance in Brazil but in addition temperature, together with annual common floor air temperature and annual common wind pace. “This paper differs from different research that often solely contemplate photo voltaic assets, not considering that the effectivity of photovoltaic modules could be very delicate to temperature,” the researchers mentioned.

The floating photovoltaic system mannequin makes use of modules from the Brazilian module producer Globo Brasil with a capability of 320 W and an effectivity of 16.49%. The mannequin assumes that every megawatt of floating photo voltaic covers roughly 10,512 sq. meters.

The outcomes present that Brazil can generate 79.37 GWh of electrical energy from floating photo voltaic yearly, equivalent to a possible put in capability of 43.28 GW. Roughly 72% of this potential corresponds to hydroelectric vegetation, with a possible put in capability of 31.5 GW and era of 57.38 GWh per 12 months.

This floating photo voltaic potential is equal to virtually the complete annual electrical energy era of Brazil’s largest hydroelectric plant Itaipu, and 12.7% of all electrical energy era in Brazil. It is going to present electrical energy to 41 million households in Brazil, 56% of the whole.

The area with the best potential is the Northeast, which mixes the perfect photo voltaic irradiance and essentially the most synthetic water our bodies, with 10.58 GW or 24.5% of the whole. It’s adopted by the Southeast with 10.08 GW (23.3%), the North with 8.5 GW (19.7%), the Heart with 8.2 GW (18.9%), and the South with 5.93 GW (13.7%).

The outcomes for every state are as follows:

  1. Minas Gerais: 6 GW
  2. Bahia: 4.59 GW
  3. São Paulo: 3.87 GW
  4. Mato Grosso do Sul: 3.73 GW
  5. Para: 3.23 GW
  6. Peak: 3.16 GW
  7. Paraná: 2.82 GW
  8. Amazonas: 2.69 GW
  9. Rio Grande do Sul: 2.65 GW
  10. Worth: 2.40 GW
  11. Tocantins: 1,214 GW
  12. Mato Grosso: 1,211 GW
  13. Rondônia: 1.18 GW
  14. Rio Grande do Norte: 816 MW
  15. Maranhão: 812 MW
  16. Paraíba: 666 MW
  17. Energy: 623 MW
  18. Pernambuco: 516 MW
  19. Santa Catarina: 463 MW
  20. Rio de Janeiro: 141 MW
  21. Alagoas: 120 MW
  22. Capability: 88 MW
  23. Espírito Santo: 68 MW
  24. Capability: 63 MW
  25. Federal District Brasilia: 59 MW
  26. Sergipe: 32 MW
  27. Hectares: 5 MW

“By masking only one% of the floor of synthetic water our bodies, it’s doable to provide 39% of the electrical energy consumption within the Heart-West, 25% within the Northeast, 42% within the North, 8% within the Southeast, and 12 % within the South. The state of Mato Grosso do Sul (MS) has all of the consumption supplied and may even export the generated vitality to a different state,” commented the scientists.

They offered their leads to “Technical potential of floating photovoltaic methods on synthetic water our bodies in Brazil,” revealed in Renewable Vitality.
