Solar Energy

Solar power plant is a large structure that transforms electrical energy from solar energy, developed for the production and distribution of electrical energy.

There are two main types: Photovoltaic and Heliothermic plants.

Solar power plants are different from residential and industrial photovoltaic systems in that they supply high voltage energy for distribution and not for own consumption and most solar parks are built on the ground. In this way, the energy production of the solar power plant comes from photovoltaic panels that convert the sun's energy into electrical energy to be sold to the grid.

How Solar Energy Works

The solar panels produce electrical energy in direct current, thus requiring a solar inverter to convert it into energy with alternating current.

These inverters deliver the energy produced by the photovoltaic panels at up to 380 Volts and to transmit to the high voltage lines, a transformer capable of raising the voltage to 13,800 Volts or 69,000 Volts or 138,000 Volts or even above 230,000Volts is required.
This electricity is then transmitted through the power transmission networks and distributed by the energy distributors for use in your home or business.

Return of the investment

Investment for 1 MW Solar Plant Project

The initial investment can be around R $ 4 to R $ 5 million, however some variables such as installed power, climatic factors and installation area can affect the value.

As it is a plant with a long useful life, around 30 years, the return on investment is guaranteed with few years of activity.

In Brazil it is considered a good investment, since Brazil has a high level of solar radiation, thus contributing to the better performance of the system.

Another factor to be taken into account is the scarcity of rainfall, which affects the reservoirs of hydroelectric plants. Thus, photovoltaic energy should be the most used source in the future.

The Solar Energy Sector in Brazil

We still have few photovoltaic plants in Brazil.

The solar energy auction in Pernambuco was the first and included the construction of more than 120 MW. In October 2019, the Agência Nacional de Energia Elétrica – ANEEL and the Câmara de Comercialização de Energia Elétrica - CCEE held the Generation Auction No. 04/2019 (A-6) where 11 photovoltaic solar plants were contracted, with the final average price of R $ 84.39 / MWh, totaling 530 MW of power and 163 average MW of physical guarantee.

The growth of solar plants in Brazil is becoming more and more common.

Currently, we already have 3,884 solar plants in operation, 19 in progress and another 194 with construction not started, according to ANEEL.

Photovoltaic Plants

Scalable economy with transmission over longer distances

The industry is responsible for at least 30% of consumption and depending on the delivery of energy and its tariffs is a constant challenge. The GNPW Group is responsible for the development of new energy generation projects, carrying out the project from start to finish.

Our technology allows the construction of photovoltaic plants in four stages with competitive advantages of economies of scale and proximity to the transmission line, reaching greater distances than conventional ones.
