Smart homes, environments equipped with devices connected to the internet and that allow automation and remote control of various functions, are the future of sustainable housing. And when it comes to residential self-sufficiency, not including photovoltaic energy in the project is almost impossible.
The growth of use of solar energy, and intelligent storage systems, in this case lithium-ion batteries, point to a future where sustainability and technology will be interconnected.
According to the mapping of ABSOLAR (Brazilian Association of Photovoltaic Solar Energy), residences lead the use of photovoltaic technology, with more than 2,8 million properties supplied, with 70% of the total consumer units.
The trend is for further growth in consumption in the residential sector, since data from EPE (Energy Research Company) projects an average increase of 3% per year over the next decade, reaching 226 TWh in 2034, with a forecast of 91 million consumers, who should use, on average, 202 kWh per month.
Photovoltaic energy represents an attractive and viable solution for those seeking to reduce their energy costs, increase sustainability and contribute to a more sustainable future.
Also according to ABSOLAR, as a clean energy source, the growth of the photovoltaic sector has contributed to avoiding the emission of approximately 45,5 million tons of CO2 in electricity production.
This growth made Brazil responsible for 4% of the global supply of photovoltaic energy in 2023, consolidating the country among the largest markets in the world.
Among the advantages of using photovoltaic energy are reduced energy costs, sustainability, compatibility with smart technologies and self-sufficiency.
Photovoltaic energy and lithium-ion batteries
The combination of solar energy and batteries allows the home to continue operating even in the event of a power outage, keeping essential devices such as security systems and lighting running. Lithium batteries, known for their durability and efficiency, have proven to be ideal for this type of storage.
In addition to taking advantage of a clean and renewable energy source, the solar energy and lithium battery system is responsible for storing excess electricity during the day, which guarantees the autonomy of automation systems, such as lights, thermostats and security systems, allowing them to be used even after sunset.
Batteries also ensure continuous supply during utility power outages, minimize extra charges for consumption peaks in industrial and commercial environments with voltage ≥ 2,3 kV, and optimize energy use during high-tariff times, taking advantage of binomial and white tariffs. In addition, they maximize self-consumption by using local generation without relying on grid connection.
With the falling cost of batteries and the advancement of solar energy, Brazil faces a major opportunity to transform its energy sector. Adopting these technologies can improve the quality of life of the population, especially in regions where energy supply faces greater challenges.
Regions such as the North and Northeast of Brazil suffer from large deficits in electricity supply, which is irregular and subject to frequent interruptions.
In remote areas, such as the Amazon and the semi-arid northeast, access to electricity is limited, and high generation and transmission costs further aggravate the problem.
In these locations, the combination of batteries and solar systems presents an efficient and viable solution to improve the energy supply.
EP5 and EP11 batteries
In August this year, Fox ESS, a unicorn valued at US$1,38 billion on the Hong Kong Stock Exchange and a leader in inverter and energy storage solutions, launched a series of products at Intersolar aimed at environmental preservation.
Highlights include the G-Max energy storage system, EP5 and EP11 batteries, EV Charger vehicle charger and the “Fox Cloud 2.0” app, which includes “Fox Forest” functionality, allowing s to track their devices and monitor energy consumption.
The batteries are fully compatible with all of the brand's hybrid inverter lines, including the H1, KH, H3, H3-Pro and US series. This compatibility is guaranteed by the t manufacturing of the batteries and inverters by Fox ESS, ensuring perfect integration between the components.
They can be connected to up to four units in parallel via a junction box, allowing flexible system expansion.
Fox ESS batteries and inverters are designed for quick and easy installation in residential, commercial or industrial environments, with floor or wall mounting options.
The brand's hybrid systems with high voltage (HV) batteries offer high efficiency, maximizing the use of stored energy and minimizing losses.
