This ppt covers how to reduce the electricity bills ..
And what is the procedure & installations process..its covers total solar panals to generation of electricity
2. Net metering is the process through which Solar PV Generator consumes and sets-off
his surplus energy/power back to the utility company(TSSPDCL) and in this process the
consumer energy bill will get reduced.
In Solar Net-metering Systems, the DC power generated from SPV panel is converted
to AC power using Inverter and is fed to the grid. The generated power during the day
time can be utilized fully by powering captive loads and excess power can be fed to the
grid as long as grid is available. In case, where Solar Power is not sufficient due to
cloud cover or during the night hours, the captive loads are served by drawing power
from the grid. The grid interactive roof top solar system can work on net metering
basis wherein the beneficiary pays to the utility on net meter reading basis only.
Net metering arrangement is a combine element of captive consumption(Import)
and exchange of power(Export) with the Grid.

4. If your home/facility consumes more power than being
produced by SPV system during a billing month, you only have
to pay for the net amount of power you draw from the grid and
in case your consumption is less than power produced by SPV
system, the excess power generated will be credited to your
account and carried over to the next months.
For example, if your Solar Plant produces 400 units over a billing
month, but you use 500 units in your facility/home, you will
have to pay energy charges on the net 100 units only.
5. Project capacity ranging from minimum 1 KWp to 5KWp
for domestic and 6KWp to 500KWp for commercial sectors
will be eligible for net metering.
The solar power generated in excess of the owner’s
electricity consumption is fed into the grid through a bi-
directional energy meter capable of registering both
import and export of electricity.
Surplus power exported by the SPV Generator to TSPDCL
will be set-off in the Settlement in every six months

6. Plant Capacity - 3Kw
Daily generation - 15units
Monthly generation - 450 units
Average monthly electricity consumption - 500 units (approx.)
of a 3 bedroom house
In Telangana domestic Cat 1B tariff slab :
0 – 200 units - Rs. 5/unit 301 - 400 - Rs. 8.50/unit
201 – 300 units - Rs. 7.20/unit 401 - 800 - Rs. 9/unit
For 500 units consumption during the month without solar shall be calculated as under :
0 – 200 units = 200x5 - Rs. 1000/-
201 – 300 units = 100x7.2 - Rs. 720/-
301 -400 units = 100x8.5 - Rs. 850/-
401 -500 units = 100x9 - Rs. 900/-
Total - Rs. 3,470/-
Bill for 500units with solar net-metering shall be accounted for as under :
Consumption = 500units – 450units (solar generation)= 50 units
For fifty units minimum bill of amount Rs 190/- will be charged
Hence, Net Bill will be Rs. 190/- and saving will be Rs. 3280/-
7. Plant Capacity - 3Kw
Plant Cost - Rs. 2,00,000/-
On the basis of current power tariff slab average - Rs. 3,280/- (approx.)
monthly saving on energy bill of 3 bedroom house
Payback period of beneficiary share :
FY 2017-18 annual saving - Rs. 3,280x10 = Rs. 32,800/- (Considering only 300 shiny days per year)
FY 2019-20 annual saving - Rs. 3,444x10 = Rs. 34,440/- (Considerings only 300 shiny days per year)
FY 2020-21 annual saving - Rs. 3,616x10 = Rs. 36,160/- (Considering only 300 shiny days per year)
FY 2021-22 annual saving - Rs. 3,797x10 = Rs. 37,970/- (Considering only 300 shiny days per year)
FY 2022-23 annual saving - Rs. 3,986x10 = Rs. 39,860/- (Considering only 300 shiny days per year)
FY 2023-24 annual saving - Rs. 4,186x5 = Rs. 20,930/- (for 5 months)
TOTAL = Rs. 2,02,160/-
Payback period of beneficiary = 5 years 5 months
Life of solar= 25 years,
Note : Calculation based on 5% average yearly escalation in power tariff
8. Plant Capacity - 5Kw
Daily generation - 25units
Monthly generation - 750 units
Average monthly electricity consumption - 800 units (approx.)
of a Commercial connection
In Telangana comnercial tariff slab :
0 – 100 units - Rs. 7.5/unit 301 - 500 - Rs. 9.40/unit
101 – 300 units - Rs. 8.90/unit Above 500 - Rs. 10/unit
For 800 units consumption during the month without solar shall be calculated as under :
0 – 100 units = 100x7.5 - Rs. 750/-
101 – 300 units = 200x8.9 - Rs. 1,780/-
301 -500 units = 200x9.4 - Rs. 1,880/-
501 -800 units = 300x10 - Rs. 3,000/-
Total - Rs. 7,410/-
Bill for 800units with solar net-metering shall be accounted for as under :
Consumption = 800units – 750units (solar generation)= 50 units
For fifty units tarif rate is Rs 6/- per unit i.e bill of amount Rs 300/- will be charged
Hence, Net Bill will be Rs. 300/- and saving will be Rs. 7110/-
9. Plant Capacity - 5Kw
Plant Cost - Rs. 3,30,000/-
On the basis of current power tariff slab average - Rs. 7,110/- (approx.)
monthly saving on energy Commercial bill
Payback period of beneficiary share :
