Grid tied or grid connected solar is a solar electricity system without batteries. Your home is hooked up to both the national grid your power smart solar electricity system, so you will always have electricity available at the flick of a switch, even at night, or if it is cloudy. You can install a solar electricity system of any size and you will only ever be billed if your power consumption is in excess of the amount you are generating.
The electricity grid acts as a 100% efficient and maintenance free battery while also providing unlimited ‘on demand energy’. This is what makes grid connected solar electricity so attractive. It has all the benefits of being attached to the electricity grid but with a portion of your electricity bill never increasing in price.
