GRID-TIED SOLAR SYSTEM
On Grid is the Most Common type of Solar Power Plant. Connecting the Solar Power Plant to the utility grid can REDUCE electricity bills by up to 90%.
ON-GRID, GRID-TIED, Utility-interactive and Grid Back Feeding are all terms used to describe the same concept – A Solar Power Plant that is connected to the utility power grid to provide bi-directional flow of power.
During the day, the solar power plant generates electricity which is used to power all electrical appliances. If enough electricity is not generated the deficit is imported from the grid itself. Likewise surplus electricity generated is exported back to the grid, with the provision to utilise the surplus anytime in the next one year. A net – meter is installed to monitor this process of import and export of electricity.
- When solar generation > running loads, excess generation is exported to grid, measured as exported power on the meter
- When solar generation < running loads, excess energy needed will be imported from the grid, measured as imported power
- When solar generation = running loads, there is no import or export
- When solar generation = zero, could be under two cases,
- When the grid is shut, solar stops generating keeping safety factors of maintenance
- During the night, where the power is imported from the grid.
A bi-directional net meter records the exported and imported electricity and the consumer is charged only for the net electricity consumed from the grid at the end of the billing cycle.
BENEFITS OF SOLAR ON-GRID Power Plant
- More use of renewable energy, thus helping keep our environment pollution free.
- 90% reduction in Electricity Bills.
- Eliminates huge space and costs required for expensive batteries.
- The lifespan of Solar Panels is Over 30 Years.
- On Grid System Pays for itself in as Low as 2 Years.
