Solar system calculator
Enter your monthly electricity bill or consumption to get a preliminary estimate of capacity, cost and payback. The exact price is determined after a site survey and engineering calculation.

Calculation assumptions
- Capacity is chosen so that annual production covers annual consumption (net-metering logic).
- Annual yield of about 1,500 kWh per kW under Armenian solar conditions (south-facing, unshaded).
- Cost is based on the average price of current package offers. Each BYD 5.12 kWh battery adds 500 000 ֏.
- One panel covers about 2.7 m² for the 630 W model.
This calculator gives a preliminary estimate. Final capacity, cost and payback are determined after an on-site survey and analysis of your real consumption.
Frequently asked questions
01 How much does an X kW solar system cost?
The cost depends on several factors: mounting type, roof type, chosen equipment and any additional work. As a guide, current offers are 750,000 AMD for a 4.1 kW system, 1,350,000 AMD for 7.4 kW and 1,950,000 AMD for 10 kW. The exact price is determined after a preliminary assessment.
02 How many kW is one solar panel?
It depends on the panel model. For example, a 630 W solar panel equals 0.63 kW.
03 How many kW would you recommend for an X m² area?
The required capacity is not determined by area alone. Our engineers calculate capacity from your real electricity consumption (monthly kWh or amount paid) and the electrical equipment you use and plan to use.
04 How many kW can fit on an X m² area?
It depends on the panel model, the shape of the area, location, roof characteristics and mounting method. Our engineers make the calculation and propose the most efficient use of the space.
05 How many panels does an X kW system include?
The number of panels depends on the panel power. For example, a roughly 10 kW system needs about 16 panels of 630 W or about 24 panels of 410 W. The final installed capacity may differ slightly depending on the configuration.
06 How do I know what capacity I need?
Our engineers analyse your current consumption and also account for planned growth. For example, if you plan an electric car, heat pump, additional air conditioners or other high-power equipment, these are included in the calculation. The optimal capacity is determined from this data.
