12v solar panels are specially designed for charging 12v batteries in many leisure and automotive applications. At Sunstore, our 12v solar panels are designed by us to generate the most efficient charging voltage and current that works effectively in the UK climate. In addition to Rohs, CE, and ISO certification, our panel has also received the highest MCS quality certification.

What are the 12v solar panels?
A 12v solar panel generates enough voltage to charge a 12v battery. Solar panels that produce 12 or 24 volts of constant voltage is optimal for everyday household usage. However, solar panels that produce 24 volts are more expensive, and many consider buying solar panels of 12 volts.

In order to increase solar system power output without changing its voltage, 12v solar panels need to be connected in parallel.

The average price of solar panel 12v
We have a variety of 12v solar panels ranging from $150 to $500 per panel.

Batteries suitable for 12v solar panels
All the solar batteries we offer are compatible with 12v solar panels. They only differ by their capacity and brands.

12v solar panels connection
The wiring of several solar panels to each other can be performed in a few different ways depending on your situation.

In parallel

Solar panels are connected in parallel using special equipment: branch connectors and a combiner box. All negative terminals are connected to one connector and all positive terminals are connected to the other connector.

With this connection, the voltage of every solar panel stays the same. The amperage from all panels adds up. This type of connection allows for increasing the amperage of the whole solar power system without raising the voltage.

In series

When connecting solar panels in series, the negative terminal of the first solar panel is connected to the positive terminal of the next solar panel, and so on.

With this type of wiring, the voltage of all panels adds up. The amperage of the system is equal to the amperage of the panel with the minimum amperage. For this reason, it is not recommended to connect solar panels with different values of the maximum current in series, since they will not work efficiently.

Series-parallel

This type of connection combines the two previous ones. Applying this method of wiring solar panels allows for regulation of the voltage and amperage within the solar power system and its most optimal mode of operation.

In series-parallel connections, solar panels are connected in series and then combined in parallel.

How to choose the right 12v solar panel
As with any solar panel, there are a few important factors that need to be taken into consideration before buying a 12V solar panel.

The efficiency of the solar panel
Power Tolerance
Low-temperature coefficient and performance in low irradiance
Warranty
The type of solar cells
