When to choose 72 cell solar panels?

EThis type of grid-connected solar panels are used for self-consumption installations in private homes, companies, farms... although nowadays it is also possible to use them in isolated solar installations together with an MPPT controller or a hybrid inverter. Evidently using solar panels of 72 cells in isolated installations we manage to reduce the investment, since we obtain the same power with less number of panels.

The panels of 72 cells offer voltages between 35 and 40 volts and can generate powers ranging from 220W to 330W. This is the main advantage of this type of solar modules; they offer more power per square meter. On the one hand we make the installation cheaper and on the other they are ideal for systems with little space available for panels.

When to choose 24 volt solar panels?

LThe 24 volt solar panels are specially designed for isolated installations for 24 volt battery charging (or two 12 volt monobloc batteries or OPzS batteries for stationary battery systems). 

The advantage of 24 volt solar panels is that they offer more power per square meter than 12 volts and generally lower the price of installations. 

In our section of solar panels you can choose what will best suit your needs, depending on where it is installed, the type of inverter, the type of batteries and the amount of energy that should be chosen. We have solar panels at 12V, 60 and 72 cells. It is not necessary to be an expert in solar panel assembly or have a broad knowledge of electricity. If we want to make our house self-sufficient with solar energy we have to make an estimate of our consumers. If our consumption is majority on weekends or weekdays, at the hours when we get higher consumption, type of household appliances, if we have LED bulbs ... etc. Depending on these variables we will choose the number of solar panels so that we can assemble to obtain the necessary power to supply our consumption. From Suministros del Sol we offer to help you in your project of efficient work your house using renewable energies through a photovoltaic installation. We advise you in the calculation of consumption and we propose a kit of solar panels to obtain the necessary power, as well as the compatibility with the different components and equipment.
