Solar Grid Tied Systems convert energy from sunlight directly into electricity. Total generation of electricity from the solar PV power plant will be exported directly through a dedicated metre for which the customer will be paid. The latter process is known as Net Metering. To learn more about it please read below. The renewable energy solutions for the residential solar grid tied systems from SolarTherm are made possible from REC and Fronius. Alpha Solar Energy Systems is the authorized distributor in Sri Lanka for REC PV panels from Singapore and a trained service partner for Fronius inverters from Austria, one of the leading inverter manufacturers in the world.

Solar Grid Tied systems convert energy from sunlight directly into electricity.
The solar panels generate electricity whenever the sun is shining. This electricity supplies the needs of the house – and then any excess is exported to the electricity grid. Simply we called as Net metering (The exported electricity is sold to the same company from which the household buys its electricity when it needs more than it’s generating.)

Alpha Solar Energy Systems is one of the first companies in Sri Lanka to recognize the value of the sun’s free energy. Our sister company Alpha Thermal Systems pioneered solar water heating in Sri Lanka in 1982 under the Brand name “Solartherm”.

As one of the pioneers in the solar electricity industry, our solar PV (photovoltaic) business stands a long undisputed reputation for quality and reliable service for the past two decades. Our installations in solar electricity industry include the largest installation in the country to date by a local turnkey contractor.

Alpha Solar Energy Systems is the authorized distributor in Sri Lanka for the “Solarworld” PV panels which is from Germany, having manufacturing plants only in Germany & USA.

Solartherm is a trained service partner for Fronius inverters which is from Austria, with local service ability for Fronius grid connected inverters.

Fronius is one of the leading inverter manufacturers in the world with over 20 years of experience having manufacturing plants in Austria.

SCHEME 01 – NET ACCOUNTING

This Scheme has introduced an additional element to Net Metering where an export tariff for the net energy exported (if any) was introduced.

If the generated units of electricity using the solar panels fixed in the roof are greater than the units consumed, the customer will be paid LKR 22.00 per unit during the first 07 years and from the 08th to 20th year LKR 15.50 per unit.

If the consumption is greater than the energy generated form the solar panels, the consumer pays the CEB at the existing electricity tariff for the excess energy consumed.

The installed capacity of the Generating Facility shall not exceed the Contract Demand of the Producer. The contract period is 20 years.

SCHEME 02 – NET PLUS

Total generation of electricity from the solar PV power plant will be exported directly through a dedicated metre for which the customer will be paid. The energy import will be measured through a separate import metre and be billed as per the existing electricity tariff.

The CEB shall read the metre to read the solar power plant output and the other metre to read the import energy. Total generation of electricity from the solar PV power plant will be exported directly through a dedicated metre for which the customer will be paid LKR 22.00 per unit during the first 07 years and from the 08th to 20th year LKR 15.50 per unit.

The energy import will be measured through a separate import metre and will be billed as per the existing electricity tariff CEB. The installed capacity of the Generating Facility shall not exceed the Contract Demand of the Producer. The contract period is 20 years.

Net Metering Schemes

SCHEME 01 – NET METERING

The electricity bill will be prepared giving credit to the export, and charging the consumer for the difference between the import and the export. If the export is more than the import in any billing period, the Consumer will receive an export credit, and will be credited towards his next month’s consumption. Such credits may be carried-over to subsequent months, as long as there is no change in the legal consumer for the premises.

SCHEME 02 – NET ACCOUNTING

This Scheme has introduced an additional element to the Scheme 01 where an export tariff for the net energy exported (if any) was introduced. If the generated units of electricity using the solar panels fixed in the roof are greater than the units consumed, the customer will be paid Rs.22.0 per unit during the first 07 yrs and from the 08th year to 20th year he will be paid Rs 15.50 per unit. If the consumption is greater than the energy generated form the solar panels, consumer has to pay to the CEB at the existing electricity tariff for the excess energy consumed. This Scheme is limited only for the Solar. The installed capacity of the Generating Facility shall not exceed the Contract Demand of the Producer. The contract period is 20 yrs.

SCHEME 03 – NET PLUS

Total generation of electricity from the solar PV power plant will be exported directly through a dedicated meter for which the customer will be paid. The energy import will be measuredthrough a separate import meter and will be billed as per the existing electricity tariff.
CEB shall read the meter to read the solar power plant output and the other meter to read the import energy. Total generation of electricity from the solar PV power plant will be exported directly through a dedicated meter for which the customer will be paid Rs 22.0 per unit during the first 07 yrs and from the 08th year to 20th year the customer will be paid Rs 15.50 per unit.
The energy import will be measured through a separate import meter and will be billed as per the existing electricity tariff CEB.
The installed capacity of the Generating Facility shall not exceed the Contract Demand of the Producer. The contract period is 20 yrs.
