Grid-tied or grid connected solar is a solar electricity system without batteries.A grid-connected PV system supplies electricity directly to households and businesses. During daylight hours, the PV panels produce a DC current. This runs through an inverter that converts the current into AC electricity. It is then suitable for electrical appliances and export to the main electricity grid.
Your home is hooked up to both the national grid and your UR Energy 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 you are power consumption is in excess ofthe amount you are generating.
Maintenance of a grid-connected PV system is generally limited to ensuring that shade from trees or other obstructions does not become a problem and occasionally checking the panels for dirt and, when necessary, cleaning them with water. 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.
