So, in this comprehensive guide, we will explore the main topics about Solar Energy, including its benefits, types of systems, useful applications, and more. Let’s go!

What is Solar Energy?

First of all, solar energy is generated from sunlight and can be converted into electricity through different technologies.

Furthermore, the main method is the use of photovoltaic panels, which transform solar radiation into electric current.

Main types

• Photovoltaic: It uses photovoltaic cells to generate electricity. It can be connected to the electrical grid (on-grid) or operate autonomously (off-grid).
• Thermal: Uses solar collectors to heat water, reducing electricity or gas consumption.
• Thermal (CSP – Concentrated Solar Power): It uses mirrors to concentrate the sun's heat and generate electricity in power plants.

Advantages

• Sustainability: Clean and renewable energy source.
• Cost Reduction: Savings on your electricity bill, with the possibility of generating energy credits.
• Low maintenance: Photovoltaic systems require little maintenance and have a long service life.
• Increase in property value: Solar-powered properties are becoming more attractive in the real estate market.
• Energy independence: Less dependence on concessionaires and protection against increases in electricity rates.

How does it work?

In summary, a photovoltaic system consists of:

• Solar panels: They capture sunlight and generate direct electric current (DC).
• Solar inverter: Converts direct current energy to alternating current (AC), used in homes and businesses.
• Fixing structures: They attach the solar panels to the roof or the ground.
• Batteries (optional): They store energy for use at night or in the event of power outages.
• Bidirectional Meter: It measures the energy generated and consumed, allowing the offsetting of energy credits on the electricity bill.

Useful applications of solar energy

Either way, technology has made it easier to plan and monitor solar energy through mobile apps.

In this sense, we have listed below some of the best apps that will help you with tasks related to the maintenance or monitoring of Solar Energy:

• SolarEdge Monitoring – Monitors the energy production of SolarEdge brand solar systems.
• Solaria – Helps calculate the feasibility and financial return of installing a solar system.
• PVWatts Calculator – Developed by NREL, it estimates solar energy production for any location.
• Sun Surveyor – Shows the position of the sun throughout the day to assist in the installation of solar panels.
• Enphase Enlighten – Allows you to monitor the efficiency of Enphase brand solar panels.

Main Companies in the Sector

Of course, there are several companies specialized in the manufacturing, installation and maintenance of solar systems.

Some of the most recognized worldwide are:

• LONGi Solar – Reference in monocrystalline solar panels.
• JA Solar – Leading Chinese company in high-efficiency solar modules.
• Canadian Solar – One of the world’s largest manufacturers of photovoltaic modules.
• Trina Solar – Chinese company known for its technological innovations.

Tips for those who want to invest

Investing in Solar Energy is undoubtedly a smart decision for those who want to save on their electricity bill and contribute to a sustainable future.

However, to ensure the best performance, good planning is essential.

Here are some key tips that can help you:

• Conduct a feasibility study: Evaluate the energy consumption of your home or business before investing.
• Choose quality equipment: Choose panels and inverters from recognized brands.
• Check out the tax incentives: In some states, there is an ICMS exemption for solar energy.
• Power Generation Tracking: Use applications to monitor system performance.
• Consider energy storage: If you want independence from the power grid, invest in solar batteries.
• Compare Companies and Budgets: Ask for proposals from different installers before signing a contract.

Solar Energy is the future!

Solar energy is undoubtedly an excellent alternative to reduce costs and contribute to the environment!

After all, with the advancement of technology and the decrease in costs, investing in this sector is becoming more and more accessible.

So, if you want to save on your electricity bill and generate clean energy, now is a good time to consider installing a photovoltaic system!
