Por isso, opto‐se por aprYearlyesenta rspecific m cen thermalário de d eenergysempe nproductionho de m s i-stkWht/mema típic2o no Brasil. Considero‐se o so de: - Standard systems in North and Northeast became •coletor de placa plana com cobertra de vidro (crva oversizedde eficiênc andia co nsaturatesforme Ma thethn thermaler et al., 2 0energy15); production because of the absence of demand. •volme do reservatório igal ao volme de ága - Higher thermal energy production causes higher consmido diariamente; money savings in South and Southeast. •relação entre volme do reservatório e área de placa 75 litros/m2; •consmo diário de 300 litros de ága aqecida a 40°C; •a temperatra da ága fria eqivale à média mensal da temperatra ambiente local. Calclando a prodção anal de energia em relação à área de coletores obtém‐se m parâmetro qe pode ser facilmente r a l transformado em resltado financeiro, considerando o preço de o S specific thermal energy production a m sistema completo e a tarifa local de energia. Os resltados Figura 46. Produção anual de energia térmica por área de coletor i 14/11/2017 1st Workshop Solar Energy - FAPESP g obtidos consideram o so de m sistema padrão para todo o país solar instalada utilizando um sistema de referência (reservatório r e = consumo diário = 300 litros; relação reservatório/área de placa n e, portanto, melhores resltados podem ser obtidos analisando E 2 individalmente cada região. A Figra 46 mostra qe ma maior = 75 litros/m ; temperatura de consumo = 40°C). e d o prodção anal de energia térmica por área de coletor instalada r i e l não está necessariamente nas regiões de maior incidência de i s a irradiação solar. Isso ocorre porqe a demanda de energia térmica r B é maior em regiões de clima mais frio (Figra 47), fazendo com qe s a l o potencial de aqecimento do sistema seja melhor aproveitado. t Para as regiões de clima mais qente, o sistema adotado nessa A simlação fica sperdimensionado, pois é capaz de fornecer mais energia térmica do qe necessária. Isso também comprova a necessidade de dimensionar o eqipamento de acordo com as características climáticas locais. Nas regiões Sdeste e Sl, a maior demanda de energia exige eqipamentos maiores, o qe faz com qe os cstos específicos dos componentes complementares do sistema sejam menores, trazendo maior retorno financeiro a essas regiões. Por otro lado, o correto dimensionamento em climas mais qentes permite ma redção de csto qe pode tornar atraente economicamente sistemas de aqecimento solar, principalmente os de grande porte. É interessante também observar o menor desempenho dos eqipamentos na região Norte provocado pela alta neblosidade. Obviamente, toda essa discssão é afetada pelos preços cobrados pela energia elétrica, qe é diferente de acordo com a concessionária prestadora do serviço e ajstado analmente pelo agente reglador de acordo com os PRORET ‐ Procedimentos de Reglação Tarifária (ANEEL, 2011). 59 Potential for CSP (kWh/m2.year) 14/11/2017 1st Workshop Solar Energy - FAPESP Fast growing PV Distributed Generation Market Source: ANEEL/ABSOLAR, 2017.
