Panel count, installation and annual benefit use the calculator engines. Installation follows actual panel power; above 20 kWp the 20 kW installation allowance is used. Roof condition, shade, string voltages, ESO connection limits and additional work require individual checks.
Payback scenario before support: annual consumption 5,760 kWh; electricity price €0.25/kWh; annual maintenance €50.00; grid recovery fee 0.0726 €/kWh. These are calculator defaults, not a current tariff offer. Payback = investment / annual net benefit. Generation and results are not guaranteed.
Grid-tied without battery: €2,914.67; Hybrid with battery: €6,003.43. Prices include 21% VAT, before support; the final quotation depends on the property.
How many panels and how much roof space are needed?
16 × 450 W = 7.2 kWp; ~36.8 m². Area is indicative; layout and actual dimensions are checked on site.
How much electricity will it generate?
~7,560 kWh/year. Assuming 1,050 kWh/kWp calculator yield; shading, orientation and weather affect the result.
Do I need a battery?
A grid-tied system works without storage. A hybrid system can shift energy use into the evening; the benefit depends on consumption and settlement. Backup operation must be checked separately.
Can I order equipment without installation?
Yes, panels in your chosen quantity, an inverter and a battery can be ordered separately or together. Cables, connectors and mounting hardware are not sold individually; they are included in an installation quotation.
