There are three main things to consider to know how to choose solar panels for a house or create a photovoltaic solar system. First of all, to calculate the solar panels for a house you need to know how much energy your battery can store and then choose a solar panel that can replenish your “reserve” of energy in the battery according to your usage pattern.

How to choose batteries for solar panels

The main function of batteries for solar panels lies in storing solar energy during the hours with light to be used during the night or for prolonged periods of low light or bad weather. Knowing which battery is suitable for our photovoltaic generation system consists mainly of the one that best suits our needs.

Regardless of its energy storage functions, batteries for solar panels also have the capacity to provide a greater current intensity than that generated by the photovoltaic system during daylight hours.

Just as each battery is different, the capacity of accumulation of energy in a device depends on the speed of discharge of the same: the longer there is in the discharge, the greater the amount of energy that the solar battery will generate.

There has always been a great debate about whether the Chinese modules are worse or better than the European ones, and many users would be surprised if they knew that a good part of the European modules are made with photovoltaic cells manufactured in China, and the only thing that some European manufacturers do is to put the glass and aluminum frame and then your brand. Just as there are good and bad European products, the same happens with Chinese products. And it’s something that has nothing to do with some unscrupulous sellers selling solar panels of debris, or with defective wafers, at prices suspiciously cheap, or even that, at normal prices.
