How Solar Energy Settlement Works in Armenia
How Armenia's autonomous electricity generation framework works: capacity limits, monthly energy balance, rollover of positive balances and the settlement year from May 1 to April 30.
The material was checked against the cited sources. A site-specific decision still needs an engineering calculation.
When a solar system produces more energy than the property is using at a given moment, an obvious question appears: what happens to the surplus?
Armenian legislation provides a framework for autonomous electricity producers that accounts for electricity supplied to the guaranteed supplier and electricity consumed by the property. In everyday language this is often described as net metering, although the most precise legal description is the autonomous generation and energy-flow framework defined by Armenian law.
The following is the basic logic under rules verified as of 14 September 2026.
1. What is an autonomous electricity producer?
Armenian law provides a framework in which a consumer can generate electricity from renewable energy resources for its own needs and interact with the electricity system under defined rules.
This allows a solar installation to function as part of a grid-connected property's energy system rather than only as an isolated source.
2. Capacity limit
Under the applicable Article 56.1 of Armenia's Energy Law, the installed capacity of an autonomous producer's generating installation cannot exceed the maximum permitted capacity specified in the consumer's contract for the relevant point of connection to the distribution grid.
There is also a statutory upper limit of 150 kW for an autonomous producer.
For an autonomous group, the total installed capacity of participating generating installations cannot exceed 1,050 kW.
This distinction is important: the 150 kW statutory ceiling does not mean that every property can automatically install 150 kW. The maximum permitted capacity of the specific grid connection is also a limiting factor.
3. What happens each month?
The law compares, on a monthly basis:
— the quantity of electricity supplied to the guaranteed supplier; — the quantity of electricity consumed by the autonomous producer.
If the difference is positive — more energy was supplied than consumed under the monthly calculation — that quantity is carried forward and added to the electricity supplied in the following month.
In simple terms, the positive energy balance rolls forward within the legal settlement mechanism.
4. What happens when consumption is higher?
If the monthly difference is negative — the property consumed more electricity than it supplied — the autonomous producer pays the guaranteed supplier for the relevant amount at the tariff established by the Commission for that consumer category.
A solar installation therefore does not eliminate the grid connection and does not automatically mean a zero electricity bill every month.
5. The settlement year
The legislation defines a specific settlement year for this mechanism:
from May 1 of each calendar year through April 30 of the following calendar year, inclusive.
This is important when evaluating the annual energy balance.
If a positive difference remains at the end of the final month of the settlement year, including balances carried over from earlier months, the guaranteed supplier pays for that remaining amount under the method defined by law, based on the annual minimum electricity sale price resulting from imbalances in the balancing market.
This should not be confused with the normal retail electricity tariff paid by consumers.
6. Why maximum system size is not automatically the best choice
The existence of an energy settlement mechanism does not mean that installing the maximum possible solar capacity is necessarily the best economic decision.
For a self-consumption solar project, the primary objective is to match generation sensibly with the property's demand.
An oversized system can require a larger upfront investment, depend more heavily on the settlement treatment of surplus energy, and consume available connection capacity without a real need.
System size should therefore be driven by consumption and project objectives, not only by available roof area.
7. Is a battery required for a grid-connected system?
No. Participation in the grid-connected autonomous generation framework does not inherently require battery storage.
A battery serves a different purpose: it physically stores electricity at the property for later use or backup.
The grid and the battery are two different energy-management tools.
8. What should be checked before final design?
Before a final proposal, verify the rules and conditions that are current on the actual project date:
— contractual permitted capacity of the connection point; — technical connection arrangement; — distributor/supplier requirements; — metering rules; — applicable tariffs; — the current version of the legislation.
This article reflects rules verified on 14 September 2026. A real project should always confirm requirements again at the date of connection.
