Generation–consumption matching and investment feasibility
This report compares the generation profile of the designed plant with the facility's consumption profile on an hourly netting basis, and presents the financial results together with the capital cost derived from the bill of materials. Energy prices are held internally in Turkish lira and converted to the report currency for display only.

Sanity check. Unit capital cost $0.568/Wp sits in the lower part of the market band; verify the project-specific roof, fire and grid items. The purchase price $0.0868/kWh assumes a regulated tariff; if a bilateral supply agreement applies, use the actual contract price.
1System summary
| Facility type | Ground-mounted | DC / AC capacity | 3,063.1 kWp / 2,450.0 kW |
| Module count and rating | 4,862 × 630 W | DC/AC ratio | 1.25 |
| Inverter count | 25 | Specific yield | 1,555 kWh/kWp |
Generation source — Energy simulation: ENERGY.result · year. The 8,760-hour generation curve was used for financial netting.
2Consumption assumptions
Consumption annual total was entered. The "office hours (08:00–18:00)" regime was used for hourly distribution, with a flat monthly seasonality. This is a model; the result may change once meter data is entered.

Paid-energy check: Of the 1,530,130 kWh exported to the grid, 1,530,130 kWh is treated as paid and 0 kWh as above the limit and subject to system usage charges. No limit was applied owing to a verified exemption.
Self-consumption ratio: 67.9% of generation was consumed on site. Sensitivity scenario (not the headline result): with monthly netting the year 1 saving would be $380,607.

6Method, regulation and data quality
Netting regime
Generation and consumption were compared separately for every hour. Board Decision no. 14531 came into force on 5 May 2026; the 2026 unlicensed-generation limit notification was issued as of 1 June 2026.
Purchase price
Derived from the active energy and distribution charges for the selected customer group, with the selected tax treatment.
Export price
The single-rate active energy price for the selected customer group was used. No further distribution deduction was applied to the paid export price.
Paid generation limit
No limit was applied; this was selected as a user-verified exemption.
Currency consistency
Tariff, export and fixed O&M values are held in Turkish lira. Finance and capital cost were converted to USD together at 1 USD = ₺47.61 · Central Bank, 07.08.2026.
Method and limitations. The generation curve is taken from the application's hourly energy simulation. The consumption profile is based on the regime assumption stated above. Material quantities are preliminary values derived from engineering ratios per kWp; the definitive bill of quantities is prepared for the specific project. Prices are entered by the user and do not constitute an offer. Grid connection conditions, distribution charges and netting regulations vary by region and date; this report is not a binding commitment.
