How does solar energy work in buildings?
The adoption of solar energy in residential buildings is based on capturing solar radiation using photovoltaic modules and converting it into electricity to meet part of the energy demand used in the common areas/recreational areas of the development.
To achieve this, the photovoltaic system converts solar radiation into electrical energy through the photovoltaic effect, which occurs in the cells present in the modules. In this process, the electricity produced is initially direct current.
Next, the solar inverter transforms this direct current into alternating current, making it compatible with the building's electrical grid and allowing its use by the systems served by the photovoltaic project.
How is the technical installation of photovoltaic panels carried out on the building?
The installation of photovoltaic panels in condominiums involves different steps to ensure that the system is suitable for the building's characteristics and the needs of the development, such as:
- Planning: Defining the photovoltaic solution from the project's conception, considering the projected demand and the project's characteristics;
- Technical assessment: analysis of the orientation, tilt, solar incidence, shading and available areas for the modules;
- Structural and electrical design: Defining the necessary conditions for receiving modules, inverters, cabling, protection devices, and other system components;
- Installation: Execution of the infrastructure and installation of the modules according to the specifications defined in the project;
- Integration into the project: Organization of the electrical infrastructure and technical areas in conjunction with the architecture, in order to preserve the functionality and aesthetics of the building.

Where does the energy generated by the photovoltaic panels in the condominium go?
In grid-connected systems, known as On-Grid systems, solar energy can be used by the development itself to meet the consumption of its systems. In high-end residential developments, for example, one possibility is to direct it to common areas, contributing especially to the operation of lighting in these areas.
When energy generation exceeds consumption at the time it is produced, the surplus can be fed into the distributor's grid. The energy sent to the grid becomes a credit and is then accounted for according to the rules of the Electric Energy Compensation System (SCEE).
Based on this compensation, and according to the distributed generation model and the configuration adopted by the development, the surplus can result in energy credits for later use, following the current rules and the registration carried out with the distributor. In this way, solar energy generation contributes to reducing the condominium's electricity costs.

What are the advantages of solar energy in buildings?
Photovoltaic generation can bring benefits related to efficiency and operating costs of the project. Among the main ones are:
Potential for savings in common areas
Self-generation can reduce some of the energy purchased from the grid to supply condominium systems, contributing to the control of electricity expenses.
Use of a renewable source
Solar energy allows for the generation of electricity from a renewable source, contributing to operations that are more aligned with sustainability practices.
Greater energy autonomy
Photovoltaic generation expands the use of an energy source produced on-site, contributing to a more diversified energy matrix and a more strategic management of condominium consumption.
Potential for asset appreciation
Energy efficiency, sustainability, and innovation are attributes that can enhance the perceived value of a high-end development over time, especially among buyers who consider these aspects when choosing a property.
How does Emplavi incorporate solar energy into high-end developments?
In Emplavi's developments that incorporate solar energy generation, the solution is part of an engineering proposal focused on efficiency and the well-being of residents.
This work begins with defining the construction solutions and extends to monitoring and quality control of the project. Furthermore, ISO 9001 and PBQP-H Level A certifications reinforce the adoption of structured processes and quality criteria in the execution of projects.
Thus, solar energy is added to a set of solutions that reflect Emplavi's commitment to performance, quality, and sustainability in its projects.
