How Your DEVDEEP SOLAR System Works
The following illustration and narrative explains how your solar electricity system works –
1.
The solar electric modules are usually fitted to the roof. The number of modules will depend on
the nominal size of your system and, collectively, they are known as the solar array. The solar
array converts sunlight into direct current (DC) electricity.
2.
The DC electricity is fed to the Inverter which is normally accessible at ground level. The Inverter
converts the DC electricity to Alternating Current (AC) electricity which is compatible with the
electricity supplied to your house from the grid. Most Inverters have a digital readout so you can
monitor information such as the amount of solar electricity produced, etc. Refer to the separate
Inverter owner’s manual for more information.
3.
Depending on Local Regulations, Your Solar system may be connected to the grid on a Net
Metering System. With Net Metering, only the Electricity not First consumed by the House will be
Exported to the Grid
.
If you have an Old Electro - Mechanical Meter (with the spinning disk), this will need to be replaced
with a Bi- Directional Meter able to record the electricity you both import and export.
Your Electricity Retailer will read your Meter monthly and Bill you for your electricity consumption.
Credit will be paid for Electricity exported to the grid at the rate of
₹
3.24 per Kwh . This is known as a
Feed-In Tariff.
System Performance
During daylight hours, your system will be generating electricity at varying rates depending on the
amount of sunshine. The more sunlight falling on the solar array the more electricity is generated,
variable factors such as cloud cover, seasonal solar angle variations, shading or soiling of the solar
array will have an effect on the electricity output. Note that you do not need to change your energy
usage lifestyle to correspond with your solar system. Your energy consumption will be supplied by
both solar and the grid.
