Solar energy: innovation and sustainability

Have you heard about solar energy? Do you know how it works and what its advantages and disadvantages are? Solar energy is a clean and sustainable energy source that comes from sunlight. It can be converted into electricity and heat through photovoltaic panels. Let's take a closer look at how this happens!

How does solar PV work?Solar PV is the direct conversion of sunlight into electrical energy. This is possible thanks to photovoltaic panels, which contain cells made of semiconductor materials such as silicon. When sunlight hits these cells, electrons are released, generating an electric current. This electricity can be used to power our homes, businesses and industries.

Which steel structures are used for solar power generation?Tessa Tecnologia e Desenvolvimento offers two steel structure options for mounting photovoltaic panels: the Carport and the Ground-mount structure.

The Carport is an innovative solution for parking lots, providing protection and shade for vehicles while generating clean energy. Made of galvanized steel, it allows solar panels to be installed, turning a simple canopy into a sustainable energy source.

The Ground-mount structure, in turn, is designed for agribusiness, allowing photovoltaic panels to be mounted in rural settings. This strong and durable structure, also made of galvanized steel, offers a sustainable solution for the countryside.

Advantages and disadvantages of solar energy

Solar energy is considered a renewable and inexhaustible energy source, obtained from the Sun. It offers numerous advantages for the environment, but it also has some disadvantages. See below:

Advantages

• Renewable and inexhaustible energy source.
• Non-polluting.
• Requires little maintenance at its generation plants.
• Solar panels are increasingly efficient and increasingly affordable.
• Viable for remote and hard-to-reach locations, as it does not require large investments in equipment maintenance.
• Excellent energy source for tropical countries such as Brazil, with intense solar radiation for much of the year.
• Requires smaller areas to be produced.

Disadvantages

• Manufacturing solar panels consumes a large amount of energy, which is sometimes greater than the energy the panels themselves generate.
• High prices compared to energy produced from non-renewable sources.
• Output varies according to weather conditions.
• Solar energy is not produced at night.
• Regions at mid/high latitudes produce little energy during winter.
• Storing this energy is less efficient compared to hydropower, fossil fuels and biomass.
• Requires an efficient storage system.

ConclusionSolar energy is an inexhaustible and sustainable source that allows sunlight to be converted into clean electricity. Through photovoltaic panels, we can take advantage of the environmental and economic benefits of this energy source. Tessa Tecnologia e Desenvolvimento plays a crucial role by providing innovative steel solutions, such as the Carport and the Ground-mount structure, that make it easier to install solar panels.

Adopting solar energy brings significant advantages, such as lower energy costs, energy independence and a contribution to a sustainable future. Although challenges remain, such as efficient storage of solar energy, technological advances and continuous investment are driving the growth of this form of energy around the world.

With its experience and commitment to innovation, Tessa plays a key role in promoting solar energy as a viable and sustainable solution. By choosing solar energy and relying on Tessa's solutions, we are building a cleaner, more economical and environmentally conscious future for everyone.
