Solar Energy
The combination of solar energy and electric mobility is changing the way many families manage electricity consumption. With a well-sized photovoltaic energy system, it is already possible to power the home and also recharge an electric car, reducing the electricity bill and increasing independence from the public grid.
According to an article published by CartaCapital on July 21, 2026, this scenario drives integrated solutions like Huawei’s FusionSolar Residential Smart PV, which combines energy generation, battery storage, intelligent management, and residential charging to make the most of the electricity produced by solar panels.
The growth of solar energy and the fleet of electric cars is transforming the residential energy sector. Instead of using electricity only to power home appliances, consumers have started to see the photovoltaic system as a way to also reduce mobility costs.

In practice, when a solar panel produces more energy than the home is consuming at that moment, the surplus can be stored or used to charge the vehicle. This allows for better utilization of daytime generation and further reduces dependency on the utility company.
Besides the savings, the solution helps reduce emissions associated with transportation and increases the energy autonomy of families.
Among the main benefits are:
To meet this new demand, Huawei developed the FusionSolar Residential Smart PV ecosystem, based on the Smart PV Residential 4.0 concept.
The architecture is named 1+4+X. At the center is an intelligent energy controller responsible for coordinating all the equipment connected to the system.
The four main components include:
The set can also be integrated with various household appliances, such as air conditioners, climate systems, and naturally, the electric car.
All management occurs through the FusionSolar app, which displays real-time information on generation, consumption, storage, and vehicle charging.
Energy storage has become one of the main evolutions of residential photovoltaic energy.
When the solar panel generates electricity above the house’s demand, this excess production can be stored in the batteries instead of being used immediately. Later, the energy can power the residence’s equipment at night or be used for charging the automobile.
The LUNA2000 batteries use LiFePO₄ (lithium iron phosphate) technology, recognized for its high thermal stability, good durability, and longer lifespan compared to other chemistries available on the market.
Another differential is the modular structure. This means the battery bank can be expanded as the residence’s consumption or the use of the electric car increases.
This also increases the potential for reducing the electricity bill, especially in properties with good solar incidence.
The residential charger SCharger was developed to work in an integrated manner with the rest of the system.
It is available in single-phase 7.4 kW and three-phase 22 kW versions, depending on the existing electrical infrastructure in the residence.
Under ideal conditions, a vehicle equipped with a battery of approximately 50 kWh can be charged overnight using previously stored energy.
One of the main differentiators is the so-called solar priority mode.
Whenever there is sufficient solar energy production, the system automatically directs this electricity to charge the vehicle before resorting to the energy supplied by the distributor.
Additionally, the equipment performs intelligent power management to avoid overloads in the electrical installation and offers authentication via app, RFID card, and Bluetooth connection.
Although many people seek an exact value to know how much they will save, the result depends on several factors.
Among the main ones are:
When the project is well planned, a large part of the energy consumed by the vehicle can be produced by the residence itself. After the return on the initial investment, the marginal cost to fuel the vehicle tends to be significantly reduced, making the electricity bill smaller over the years.
Besides the residential charger, the investment usually includes photovoltaic modules, inverter, batteries, electrical project, and installation, whose value varies according to the desired power.
The growth of electric mobility also drives residential infrastructure. In recent years, the number of public charging stations in Brazil has increased, while manufacturers of electrical equipment have started investing in increasingly intelligent home chargers.
Simultaneously, regulatory changes in various states and municipalities have facilitated the installation of individual chargers in condominiums, expanding consumers’ access to technology. Huawei also develops the FusionCharge line, aimed at the commercial market.
Unlike the residential system, these devices use significantly higher power and serve charging stations, gas stations, shopping centers, and rapid charging corridors. This strategy shows that the company seeks to operate at different stages of the infrastructure necessary for the growth of electric mobility.
For those who already have solar energy or intend to install a photovoltaic energy system, integrating the charging of the electric car represents an important step towards more efficient energy management.
The main advantage lies in the automatic coordination between generation, storage, household consumption, and vehicle supply. Instead of operating separate equipment, the system distributes the available energy according to the needs of the house, making better use of each kilowatt-hour produced by the solar panel.
Although the initial investment is still significant, experts point out that the combination of distributed generation, smart storage, and electric mobility is expected to gain ground in the coming years. As more consumers seek to reduce the electricity bill and increase energy autonomy, integrated solutions like FusionSolar are likely to become increasingly present in Brazilian homes, uniting economy, technology, and sustainability in a single ecosystem.
