Hybrid solar systems generate power in the same way as a common grid-tie solar system but use batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.

Traditionally the term hybrid referred to two generation sources such as wind and solar but more recently the term 'hybrid solar' refers to a combination of solar and battery storage which unlike off-grid systems is connected to the electricity grid.


An off-grid system is not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is less sunlight.

The high cost of batteries and inverters means off-grid systems are much more expensive than on-grid systems and so are usually only needed in more remote areas that are far from the electricity grid. However battery costs are reducing rapidly, so there is now a growing market for off-grid solar battery systems even in cities and towns.


You know your air conditioning system keeps your home or business cool in the hot summer months, but have you ever wondered how it works? One interesting fact you might not know is that your air conditioner and your refrigerator work primarily the same way. The difference is your refrigerator cools a small, insulated space, and an air conditioner keeps your home, office, or commercial space at a comfortable temperature.

The entire process of making the air in your property a comfortable temperature is based on a very simple scientific principle, and the rest is achieved by mechanical means.
