New database for Brazil’s solar generation potential – pv magazine International

From pv journal Brasil

Scientists from Brazil, Colombia, and Germany have created a database of PV era potential in every Brazilian state, utilizing 2019 as a reference yr for photo voltaic irradiation. The researchers intention to make use of present power information in Brazil – together with the Siga database of the nationwide electrical energy regulator and information from the Vitality Analysis Workplace (EPE) – and make it extra accessible​​​​ the worldwide neighborhood.

“By offering the primary publicly out there, spatially clear, appropriate, English-language model of Brazil’s power information, we enable researchers to duplicate the Brazilian power system and/or enhance the combination of world power mannequin, ranging from a standard base,” the scientists. mentioned.

To calculate the photo voltaic era potential of every state, the crew used the Vitality Information Evaluation Instrument (EnDAT), which till now was solely out there inside the German Aerospace Middle.

The mannequin makes use of two maps to calculate the potential for photo voltaic era – one which identifies the areas which are excluded, and the opposite that serves as an acceptable criterion for figuring out the out there space. The utmost density of the installations is calculated by contemplating the utmost shading impact of the modules with an optimized angle for the winter solstice. The potential is decided for photo voltaic installations on roofs, facades, different open city areas, and areas appropriate for large-scale installations positioned on the bottom.

In whole, Brazil has the potential to put in 337.83 GW of photo voltaic, in accordance with the examine. The outcomes for all 27 Brazilian states are as follows:

1. Bahia (BA): 43.97 GW
2. Minas Gerais (MG): 41.84 GW
3. Mato Grosso (MT): 39.73 GW
4. Goiás (GO): 24.40 GW
5. Para (PA): 21.28 GW
6. Mato Grosso do Sul (MS): 19.62 GW
7. Piauí (PI): 17.05 GW
8. Maranhão (MA): 16.46 GW
9. Tocantins (TO): 14.76 GW
10. Rio Grande do Sul (RS): 13.28 GW
11. São Paulo (SP): 12.42 GW
12. Ceara (CE): 11.94 GW
13. Pernambuco (PE): 9.37 GW
14. Rondônia (RO): 8.66 GW
15. Paraná (PR): 8.28 GW
16. Roraima (RR): 6.72 GW
17. Paraíba (PB): 5.63 GW
18. Rio Grande do Norte (RN): 4.44 GW
19. Espírito Santo (ES): 3.08 GW
20. Santa Catarina (SC): 2.93 GW
21. Amazonas (AM): 2.91 GW
22. Alagoas (AL): 2.54 GW
23. Rio de Janeiro (RJ): 2.06 GW
24. Sergipe (SE): 1.94 GW
25. Acre (AC): 1.56 GW
26. Instructing (AP): 0.99 GW
27. Brazil’s capital Brasilia (DF): 0.27 MW

The researchers describe their mannequin within the “Harmonized and Open Vitality Dataset for Modeling a Extremely Renewable Brazilian Energy System” not too long ago printed in Scientific Information. The dataset of potential put in capability, in addition to different info, will be accessed right here.
