While installing solar plants, KSEB A bi-directional meter that measures the difference between the electricity used from the grid (import) and the electricity sent to the grid (export) and a solar meter that measures the electricity generated by the solar plant should be installed. They can be purchased by the customer on their own. KSEB The prevailing monthly rent is applicable at the time of installation of meters. The applicant should inform himself in advance for testing the meters he will purchase on his own.
The net reading (export-import surplus) on the bi-directional meter shall be used for billing. When the import is over, the consumer will be billed at the prevailing rate for the surplus power. However, when the shipment is retained, the customer does not have to pay. And surplus electricity can be used next month. This may continue in the coming months. Finally, if there is an export surplus in meters on 30th September every year, that much electricity will be sold to KSEB. Price for purchase consideration will give Thus the period from October 1 to September 30 is called the
settlement period. As determined by the Regulatory Commission, KSEB The
price will be based on the average purchase price of electricity
purchased from abroad.
Multiple consumer premises solar power systems can be connected to the power distribution network, one per consumer premises.Electricity generated at one location can be used elsewhere by the same
customer. The following conditions apply to it.
(1) Connection
agreement at those locations should be in own name,
(2) Export surplus
at generation location (after deducting consumption at consumer premises
generating solar energy) should be 500 units or more per month,
(3)
Priority of locations should be intimated in advance along with
application,
(4) 5% of export surplus less for distribution loss and
other expenses.
T.O.D. (Time-of-day)
based on the usage of solar power generated by consumers in (1) first
peak period from 6 AM to 6 PM (Normal Period), (2) if there is surplus,
then from 6 PM to 10 PM (Peak Period),( 3) Again if there is surplus it
is from 10 pm to 6 am will be considered used during (off-peak period).
Design, quality of construction, installation and safe operation of
solar power plants shall be the sole responsibility of the customer. The
plants are to be installed and operated as per the Central Electricity
Authority's regulation "Technical Standards of Connectivity for
Distributed Generation Resources", 2013.
KSEB in emergencies. If requested, the solar system shall be allowed to be inspected.
Procedures for approval
1]Solar Power Plants KSEB For connection to the network of, the
application in
Annexure-1 should be filled and submitted to the
Electrical Section Offices at the respective location.
Before submitting the application, you should verify your connected load is enough for submitting Anexxure 1. In the case of single phase domestic consumer upto 5kWp can be installed without considering connected load. But in other tariffs, connected load should be match with your requirement.
If you wish to install a 3 kWp plant in your shop its connected load should be greater than or equal to 3000 Watts.
1000 as
application fee should be paid in cash or by bank demand draft drawn in
the name of Assistant Engineer.
Amount to Pay with GST-1180/-
2]The
applicant will be informed through a Feasibility Certificate within 15
days after verifying whether the plant can be connected to the
distribution network. It is valid for 30 days. Intending to install the
station
The maximum solar capacity that can be connected on that feeder is 80% of the minimum load on the feeder.
Relationship between DTR Capacity and Feasiblity can be explained as follows :
If Capacity of DTR is 100 kVA. If power factor is assumed as 0.9 total kW=90. Then 75 % of total load is 67 kw will be the maximum allowable solar plant capacity in that DTR.If the capacity is over, enhancement of DTR is necessary.
Similarly in the case of other DTRs.
160 kVA-108 kW
250 kVA-169 kW
315 kVA- 213 kW
The availability of DTR for solar installation can be check using the
link.
3]Then within 30 days from the date of prospectus the applicant should
register in the application form in

Note:
As per circular issued by KSEB dated 12/04/22 testing procedures of Roof top solar plants have been eased. Such a circular has been issued considering the rapid spread of solar plants. According to this,
1. Roof top solar plants with capacity of 50 kilowatt peak (kWp) and below will no longer require grid connectivity testing by KSEB.
2. Inverters used in such solar plants before providing grid connectivity , Electrical section offices should ensure that IS certified and anti-islanding protection is provided.
3. Net meter and renewable meter (solar meter) should be placed so as to enable reading (essentially eliminating the need to place both next to each other)
4. Electrical Inspectorate testing / energization sanction will be applicable only for plants having capacity of 10 kilowatt(kWp) and above.
5. Inspectorate scheme approval is not required for plants up to 30 KW peak capacity. But the Energization Certificate is applicable for plants with peak capacity of 10 to 30 KW.
6. It is the responsibility of the Electrical Section Office to provide grid connectivity within 15 days after the customer submits the completion report of the plants with a capacity of up to 100 kilowatt peak.
7. 10% of new plants up to 50 KW under each Section Office will be subjected to KSEB testing. Renewable Energy and Energy Savings will take appropriate action if such testing fails.
* This is applicable to both those who are covered by the solar scheme and those who are not.
