Brazil's Installed PV Capacity Is Already Equal To Itaipu Hydropower Station (14GW)

Mae defnydd ffotofoltäig ym Mrasil wedi cynyddu'n sylweddol, gyda'r wlad bellach yn cynhyrchu 14 gigawat (GW) o drydan, sy'n cyfateb i orsaf bŵer trydan dŵr Itaipu. Daw'r data gan Gymdeithas Ffotofoltäig Brasil (Absolar) ac mae'n dangos potensial enfawr ynni ffotofoltäig ar gyfer cartrefi, busnesau a diwydiant.

The study considered centralized power generation parks—large-scale centralized power plants as well as distributed power plants, i.e. photovoltaic power plants installed on roofs, facades, or land.

Ar wahân i'r rhan ariannol, mae PV yn dal i fod yn dda i'r amgylchedd ynghyd â'r arbedion mewn costau trydan yn y tymor canolig a'r hirdymor. Yn ôl canlyniadau ymchwil Absolar ym Mrasil, mae 18 miliwn o dunelli o effaith lleihau allyriadau carbon deuocsid wedi'i gyflawni trwy fabwysiadu cynhyrchu pŵer glân.

"The price of electricity generated by large photovoltaic plants is ten times lower than that of fossil thermal plants or electricity imported from neighbouring countries, which are the two main factors leading to increased tariffs for consumers," said Rodrigo Sauaia, president of Absolar.

For 2022, the agency still expects Brazil's PV market to maintain the same accelerated growth in previous years, mainly due to Brazil's Law No. 14,300/2022, which establishes a legal framework for higher electricity prices for self-generated electricity. More Brazilians are likely to install photovoltaic panels in their homes or buildings to take advantage of Brazil's good light conditions.

Large-scale photovoltaic power plants in Brazil have an installed capacity of 4.7 GW, equivalent to 2.4 percent of the country's overall installed electricity capacity. Brazil is the sixth largest source of electricity generation in Brazil, spread across 19 states in almost all regions of the country, with 31.6 GW of projects approved for development.

Brasil yn pasio deddfwriaeth i annog y defnydd o ynni ffotofoltäig

For the past 10 years, Brazilians have been living with high energy prices due to scarce rain. Because of the country's high reliance on hydroelectric power, when reservoir water levels drop too low, electricity production falls and the price charged to consumers to sell electricity continues to rise. Brazil's major megacities São Paulo, Rio de Janeiro and Brasilia are examples of megacities that have recently experienced a similar situation - in the capital Brasilia, residents still pay high electricity bills.

Cyhoeddwyd y fframwaith cyfreithiol ar gyfer hunan-gynhyrchu ar ddechrau'r flwyddyn hon, a sefydlwyd cyfnod pontio tan 2045 i annog datblygiad parhaus y diwydiant. Hyd at Ionawr 2023, bydd defnyddwyr sy'n gosod systemau PV ar eu toeau neu ar y ddaear yn cael triniaeth o dan yr holl reolau cyfredol am y 22 mlynedd nesaf.

O'i gymharu â ffynonellau ynni adnewyddadwy eraill, mae gan ffotofoltäig fanteision amlwg o hyd, a all arbed buddsoddiad cyfalaf yn effeithiol, hyrwyddo cynaliadwyedd a lleihau cost systemau cynhyrchu pŵer traddodiadol.
