Hybrid renewable energy system incorporates several types of energy such as photovoltaics, wind generators, grid and energy storage system. Hybrid systems offer a high energy security as a combination of generation system and they have a storage system such as lithium battery banks.
You have the guaranteed electricity supply of the grid and you can also store your excess energy from the solar panel for use in one sunny day when the situation is reversed. This usually brings down your dependency of grid imports by 70% to 95%.
This is true unless the grid-connect solar power system is a hybrid system in which there are batteries and a battery inverter. A hybrid system normally has the capacity to charge the batteries with excess solar energy- this is the cheapest source of energy in existence. When batteries are fully charged, the excess solar is fed back to the grid and you make money out of it.
If there is a lack of solar power for fear of powering your home, the battery inverter will try to provide power from the battery. If it cannot meet the required power need due to the fact that it is flat, then the power grid will supplement the rest. Companies set up hybrid systems in a manner that your house is powered by solar energy, followed by the battery and the last one being the grid
