The amount of energy you consume

Depending on the manufacturing technology, they can be:
a) Monoblock batteries : most common in isolated, low-consumption or sporadic use installations . Their useful life is approximately 4 to 5 years and they have little capacity.
b) Stationary batteries : for installations with medium-high consumption . They can be used daily and have a very optimal performance.
c) Gel batteries: ideal for medium or large-sized installations where high power is needed for long periods of time.
d) AGM batteries : recommended for small installations such as self-consumption in motorhomes. They have a useful life ranging from 5 to 10 years.
e) Lithium batteries: the longest lasting and with very fast charging times. They can be used in any installation without the need for maintenance.
Smarter batteries can collect consumption data or even weather forecasts or the cost of electricity.
How many solar panels and batteries do I need to be self-sufficient?

If you want to clear up any doubts right now, you can enter our solar simulator and fill in your consumption data. You will receive a pre-offer tailored to your needs and you will know how many panels you need.
The same thing happens with batteries and each case must phone number list be analyzed. However, we are going to share the factors that are analyzed to decide which batteries a photovoltaic installation needs:
: It is important that this study includes the months with the lowest solar radiation (usually winter) because that is when you will need to use the batteries the most.
Remember that photovoltaic panels also absorb solar energy in winter , but if there are fewer hours of daylight, there is also less solar radiation . Therefore, performance drops to 20% of normal capacity. However, the energy received by the panels is equally useful and, most importantly, it is more than enough for the installation to operate at full capacity , as at any other time of the year. In addition, thanks to these energy storage systems, you can ensure that you have renewable electricity in your home and maximize the self-consumption installation.
The size of the installation itself : if it is a residential type for self-consumption and, for example, 12 340 W panels have been installed , a 2.5 kW battery is recommended .
Battery voltage: 12V, 24V and 48V batteries can generally be found
12V Suitable for 1 kW power and monthly consumption of less than 100 kWh. That is, occasional and low consumption, such as second homes or country houses.
24V High consumption, between 100 and 150 kWh, with power between 1 and 5 kW.
48V Consumption of large photovoltaic installations.
On the other hand, capacity is the amount of energy that can be stored. When choosing, since a study will have been carried out first, it will already be known how much the installation consumes and how much energy needs to be stored.
But what does the capacity of a battery depend on? Mainly on the time and speed of discharge , data that can be seen on the battery labels.
Download time: This is a number that starts with a "C" and indicates the hours required for download.
Discharge current: is the capacity or supply flow of the battery and is expressed in amps per hour.
For example, a C100 and 140 Ah battery is discharged after 100 hours through a current of 140 Ah.
How much does a solar panel accumulator cost?
The price depends on the technical characteristics, but can range from €1,500 to €2,000. If the power is very high, it can reach €5,000. It is always best to seek advice from a professional.
How long does a solar energy accumulator last?
On the other hand, the useful life depends on the number of times the battery is charged and discharged. In other words, the frequency of use is more important than the time the batteries are working. There are models that last about 10 years and others up to 20. And when you ask a specialist for advice, they will surely also give you advice on how to use it properly so that it lasts longer and, most importantly, in good condition.
