On-grid or grid-tie solar systems are by far the most common and widely used by homes and businesses. These systems do not need batteries and use common solar inverters and are connected to the public electricity grid. Any excess solar power that you generate is
exported to the electricity grid and you usually get paid a feed-in-tariff (FiT) or credits for the energy you export.
Dubai Net Energy Metering
1- If you enroll in Dubai’s net metering program, the first step involves connecting your solar PV system to the utility grid.
Doing so ensures you’ll always have 24/7 access to reliable electricity – either from: Your solar panels during the day.
DEWA’s utility network at night Because your solar installation is grid-tied, there’s no need to install on-site batteries
to power your facility once the sun goes down.
2- The next step in the net metering process involves outfitting your solar installation with a bidirectional electricity meter that logs:
Any utility power you take from DEWA’s grid. Any surplus solar power you feed into the grid.
3 – At the end of that billing cycle, you only pay the “net” difference in electricity consumed and fed. This automatically makes your utility bills much lower than they’d be without net metering. In fact, many of our customers are surprised when they start receiving negative electricity bills in the mail. When this happens, DEWA will provide you with utility credits that you can apply to any future statement. Moreover, this usually isn’t a one-off event.
4 – Provided you send enough surplus electricity into the grid, it’s possible to have negative utility bills month after month. And this is pretty easy to do if your home is frequently empty during the day due to work or travel. In case of work facility it is assumed not all the devices are running together & consuming power, hence, All the daytime power from your solar installation generates utility credits, So you just save and save additionally
