WHICH IS SELF-CONSUMPTION WITH BATTERIES
When we talk about self-consumption we are talking about producing your own electricity for your own consumption, in this article we will talk about what self-consumption is with batteries.
The installations of solar panels for self-consumption are becoming one of the fastest growing sources of electricity generation in Spain.
WHICH IS SELF-CONSUMPTION WITH BATTERIES
This increase in the popularity of self-consumption has led to the birth of another renewable technology: smart batteries that can store solar energy that is not used for later use.
Companies such as Tesla, LG or Ampere Energy are developing batteries that can be installed together with solar panels to create intelligent production and storage systems for your home or business. Keep reading this article to get more information about solar batteries, and discover if self-consumption with storage is the right option for you.
The cost of solar panels and self-consumption is falling throughout the country.
Solar storage: self-consumption with batteries in your house
To understand why you can choose to install a solar storage system in your home, you must first understand how a solar power installation works.
A typical photovoltaic installation includes solar panels, an inverter, structures for mounting the panels on the roof and a monitoring system that measures the production of electricity in real time. Solar panels collect the energy of the sun and convert it into electricity. It passes through the inverter and is transformed so you can use it in your home.
The vast majority of self – consumption facilities are connected to the electricity grid. In this case, if the plates produce more electricity than you are consuming in your home during sunny hours, the excess is poured into the electricity grid for free. But, in the hours where there is no sunlight and you do not have electric batteries, you can consume the electricity you need directly from the electricity grid.
How do the solar panels charge the batteries used for self-consumption?
Solar batteries capture the excess energy produced by photovoltaic panels that are not consumed instantaneously and store it for later use. In some cases, the batteries have their own inverter.
When you install an intelligent battery as part of your energy self – consumption system , you can store the excess electrical energy produced by your plates instead of sending it to the network. If your photovoltaic panels are producing more electricity than you need, this excess energy is used to charge the battery.
Later, when your photovoltaic panels are not producing electricity (at night for example), you can use the energy that the smart battery stored during the sunny hours. It will only send electricity to the grid when the battery is fully charged, and will only draw electricity from the grid when the battery runs out.
What this means, in practical terms, is that houses with photovoltaic installations composed of smart batteries plus solar panels can store the excess energy, to be used later when the sun is not shining.
As an additional benefit, since smart batteries store energy in your home or business, they also offer backup power in the event of a power outage.
Energy storage can be useful even without solar energy
Although batteries are usually combined with solar panels, they can also be useful without them. Small-scale energy storage, the technology used in solar storage and storage systems, can also be charged with electricity from the grid to provide backup power without the need for a backup generator powered by diesel. or gasoline.
Should I install a battery in my house?
Whether it compensates you to install or not a battery for your solar panels depends on the way you consume energy and how high your electricity bill. If you have a house isolated from the electricity grid, have a very high bill or consume most of the energy during the night, it is probably interesting to install a battery next to your self-consumption installation.
Energy storage in the network: Self-consumption and distributed generation
To this day, solar batteries and other energy storage technologies are not easily found and are not well established in the market, but this situation will be reversed in the short term. Why is energy storage expected to grow at such a rapid pace?
The benefit offered by self-consumption with batteries to the owners of a house or company, that is, the capacity to store renewable electricity for later use, can also be applied at a higher level for the entire electricity network.
Large-scale energy storage technologies, such as smart batteries, provide power companies and users with more flexibility in the way they generate and use electricity, in particular, from renewable energy sources such as solar energy and the wind.
Power companies, distributors and network administrators have a complex task. They must provide their customers with constant and reliable electricity access for their homes and businesses. To achieve this, they must ensure that there is enough electricity in the network to meet the demand.
If there is too little or too much electricity in the system at any given time, customers are more likely to experience blackouts.
This careful balance between supply and demand becomes even more challenging as more renewable resources, such as solar and wind power, are added to the grid .
Solar panels produce electricity when the sun is shining, and wind turbines produce electricity when the wind blows. Unlike traditional thermal power plants powered by coal or natural gas, production with solar panels and wind turbines can not be increased rapidly to meet demand. We can not force the sun to go out at night!
By installing more energy storage technologies, such as smart batteries, power companies and network operators can more easily manage the flow of electricity from renewable resources.
In the long term, this means more renewable energy resources integrated into our country’s electricity mix, including domestic self-consumption facilities .
