More and more television networks are investing in energy efficiency projects. After NDTV Group, based in Florianópolis (SC), receives a 2.6 MWp plant, it’s time for TV Nova Nordeste install a photovoltaic system to reduce energy costs.
The group, located in Olinda (PE), is obtaining a savings of R$ 52 thousand monthly (R$ 624 thousand annually) with one 396 kWp plant built in the city of Gravatá (PE). The amount will be used for improvements and expansions of the TV itself.
According to the Solartech, the company responsible for the project, work on the project began in December 2021 and was completed in February 2023.
In total, they used 720 550 W photovoltaic modules from Jinko Solar and JA Solar, four 75 kW inverters from Sungrow and a 300 kW substation.
“The system has the capacity to supply 280 homes per year with 200 kWh of monthly consumption,” said Carlos Henrique Buarque, director of New Business at Solartech.
“This was a successful case due to the operational costs that underwent several changes in values throughout the project period, which lasted one year. However, with a lot of effort, we managed to keep all values within what was initially agreed”, highlighted Buarque.
Division of works
The executive commented that the works were divided into six stages. Each stage corresponded to the purchase of material, mobilization, implementation and testing of connections.
- Step 1: cleaning the land; implementation of metallic structure;
- substation implementation; and the inverter house;
- Step 02: implementation of the first inverter and 180 550 W modules;
- Step 03: implementation of the second inverter and 180 550 W modules;
- Step 04: implementation of the third inverter and 180 550 W modules;
- Step 05: implementation of the fourth inverter and 180 550 W modules;
- Step 06: implementation of the blanket, gravel and fence with barbed wire.
“We had in mind the assembly of the plant in a single stage, however during the project the client chose to divide it into six so as not to decapitalize and wait for the concessionaire's procedures to connect the substation and the system in its entirety”, explained Buarque.
Another challenging point, according to him, was leaving the entire plant standardized with the initial characteristics, “especially in the last stage where the entire market was heated with sales due to the deadline of Law 14,300”, he concluded.
