Solar photovoltaic energy to accelerate the energy transition
At Solarig, we develop, build and operate large-scale solar PV plants that generate renewable electricity, drive decarbonisation and create long-term value in the regions where we operate.
What is solar photovoltaic energy?
Solar photovoltaic energy converts solar radiation directly into electricity through the photovoltaic effect. Thanks to its efficiency, scalability and competitiveness, it has become one of the key technologies driving the energy transition and the shift towards a decarbonised electricity system.
Today, solar PV plants can generate renewable energy at scale, integrate with energy storage systems and supply both industrial consumers and national electricity grids.
How does a solar photovoltaic plant work?
A solar photovoltaic plant converts solar radiation into electricity through photovoltaic modules that generate direct current. Inverters then convert this energy into alternating current so that it can be transmitted and integrated into the electricity grid. Finally, transformers increase the voltage and the electricity is distributed to homes, industries and infrastructure.
Solar radiation
Sunlight reaches the photovoltaic modules.
Photovoltaic modules
Solar cells convert solar radiation into direct current.
Inverters
They convert direct current into alternating current.
Voltage transformation
The voltage is increased to transmit electricity efficiently.
Electricity grid
Renewable electricity is fed into the grid for distribution.
Why is solar photovoltaic energy a key technology?
Solar photovoltaic energy has become one of the pillars of the energy transition thanks to its ability to generate clean electricity, reduce emissions and adapt to different energy needs.
Decarbonisation
Solar photovoltaic energy generates electricity without direct emissions during operation, helping to reduce the carbon footprint of the energy system.
Competitiveness
Thanks to technological advances and the continued reduction in costs, solar energy is one of the most competitive sources of electricity generation worldwide.

FAQs about solar photovoltaic energy
We answer some of the most common questions about how solar PV plants work, their benefits and Solarig’s role in the development, construction and operation of large-scale solar projects.
What is solar photovoltaic energy? +
Solar photovoltaic energy converts solar radiation directly into electricity through photovoltaic modules. It is a renewable, scalable and competitive technology that enables clean electricity generation in both self-consumption installations and large-scale solar plants.
What is the difference between solar photovoltaic and solar thermal energy? +
Solar photovoltaic energy converts solar radiation into electricity through photovoltaic modules. Solar thermal energy, by contrast, harnesses the sun's heat to produce hot water, heating or thermal energy. At Solarig, our focus is on the development, construction and operation of large-scale solar PV projects.
How does a solar photovoltaic plant work? +
A solar photovoltaic plant captures solar radiation through photovoltaic modules, which generate direct current. Inverters then convert this electricity into alternating current, transformers increase the voltage and the electricity is fed into the grid for distribution.
What are the benefits of solar photovoltaic energy? +
Solar photovoltaic energy generates renewable electricity without direct emissions during operation, reduces dependence on fossil fuels and contributes to the decarbonisation of the energy system. It can also be integrated with energy storage solutions to increase grid flexibility.
How long does a solar photovoltaic plant last? +
A solar photovoltaic plant is designed to operate for decades. Its performance depends on equipment quality, technical design, environmental conditions and effective operations and maintenance. Continuous monitoring and optimisation help protect the value of the asset throughout its operational life.
What services does Solarig provide for solar PV projects? +
Solarig supports solar PV projects throughout their entire lifecycle, integrating capabilities across development, engineering, EPC construction, operations and maintenance, performance optimisation and renewable asset management.
What is the difference between solar PV development, EPC and operations? +
Solar PV development includes site identification, feasibility studies, permitting and grid connection. EPC encompasses engineering, equipment procurement and plant construction. Operations focus on monitoring, maintaining and optimising the asset throughout its operational life.
What role does energy storage play in a solar plant? +
Energy storage, particularly through BESS, enables the energy generated by a solar PV plant to be managed more effectively. It helps improve electricity system stability, increase grid flexibility and make better use of renewable energy during periods of higher demand.
How does Solarig contribute to the energy transition? +
Solarig contributes to the energy transition through the development, financing, construction, operations and maintenance of renewable energy infrastructure. In solar PV, we support projects throughout their entire lifecycle and apply our international experience to improve their efficiency, performance and long-term value.
