If we have two or more solar panels with equal current and power, and we want to increase the voltage, the choice falls on the series connection. By connecting multiple solar panels in series, we increase the system voltage. In a solar power system, the higher the voltage and the lower the energy losses along the cables.
Off-grid systems have a bit more flexibility and solar owners will sometimes connect their panels in parallel to meet their battery needs (12 volt solar system to charge a 12 volt battery, for example). It is also possible to install solar as a combination of series and parallel circuits to try and maximize the advantages of both types of wiring.
The lower the threshold voltage, the lower the dissipation of solar power on the diode. If we have two or more solar panels with the same voltage but with different current, it is NOT possible to wire them in series. Nonetheless it is possible to wire them in parallel.

Grid connected PV systems always have a connection to the public electricity grid via a suitable inverter because a photovoltaic panel or array (multiple PV panels) only deliver DC power. As well as the solar panels, the additional components that make up a grid connected PV system compared to a stand alone PV system are:
The main advantage of a grid connected PV system is its simplicity, relatively low operating and maintenance costs as well as reduced electricity bills. The disadvantage however is that a sufficient number of solar panels need to be installed to generate the required amount of excess power.
In recent years, however, the number of solar powered homes connected to the local electricity grid has increased dramatically. These Grid Connected PV Systems have solar panels that provide some or even most of their power needs during the day time, while still being connected to the local electrical grid network during the night time.
Solar powered PV systems can sometimes produce more electricity than is actually needed or consumed, especially during the long hot summer months. This extra or surplus electricity is either stored in batteries or as in most grid connected PV systems, fed directly back into the electrical grid network.
