Which technology is used in Batteries for storage systems? The characteristics of photovoltaic storage systems depend on the material chosen for the battery. The self-production and self-consumption of energy obtained from your photovoltaic panels allows you to become independent from the myriad of offers of network operators and to make your contribution to create a more sustainable world, shifting the balance from fossil fuels to renewable energies.
This transition, however, has to deal with some intrinsic aspects of using the sun to power one’s home: the most obvious element is its absence during the night or in case of bad weather, leaving the photovoltaic panels without their source of energy. However, now solar panels are quite effective that they can store enough energy to meet the needs of electricity for 24 hours.
Solar is an easier technology to adopt privately than other renewable sources such as wind and hydroelectric. To make it easier to create an eco-sustainable world and a conscience shared by all citizens, maximizing the potential offered by the sun, different devices have been created to accumulate the energy produced by photovoltaic systems.
In this way it is possible to have an electric reserve for the night hours and in case of bad weather: the actual storage capacity of the photovoltaic energy depends on the technologies, which differ above all as regards the battery itself. In fact, different materials are available to make them, each with its own characteristics:
Types of materials used in Solar batteries
Lead-acid: This is the same technology used for car batteries and which has been transposed and adapted for integration with photovoltaic systems. Therefore, being made with an already consolidated process, they are the most widespread and competitive ones on the market; however, they also have a number of disadvantages precisely because it is a technology that has already reached its peak of development.
Lead-acid batteries are very bulky and heavy, and can withstand a limited number of charge-discharge cycles; in addition, this duration is only guaranteed if they are not discharged for more than 50% of their storage capacity, basically halving the storage capacity you can say.
Nickel cadmium: Ideal for colder climates, their storage capacity is not affected by low temperatures, but is below average compared to other batteries; the cadmium-free version, on the other hand, exhibits a storage capacity three times higher for the same size, which can be used completely in the discharge phase without repercussions
Lithium-ion: Similarly, to the case of lead-acid, this is a technology already applied elsewhere, with a widespread use of lithium batteries in electronic instruments for everyday use such as laptops. However, having a more recent history, the use of lithium ions is still evolving, with constant research and development efforts to improve storage capacity and efficiency without increasing the size of the battery. These efforts have resulted in photovoltaic storage systems with a long-life cycle and a large capacity with extremely small dimensions.
Innovations to make solar panels more and more efficient
International research is developing new solutions for photovoltaic panels, to spread this technology more and more also at a residential level.
The reduction of CO 2 emissions is considered by many countries to be crucial for the well-being of our planet and this goal can only be achieved with the support of people, who must internalize a sense of responsibility towards the environment, and of research, which must propose increasingly efficient and accessible solutions to meet energy needs using renewable sources.
That’s the power of solar technology and we can consult Zero Carbon as well if we want to buy latest models for solar panels and solar batteries. These advanced level batteries or solar panels are available at cheaper rates and they can save a lot of electricity cost from your monthly bills.
