Compare with and without a battery using your own production, usage, electricity price and quote.
The estimate values only electricity you use directly at home. It assigns no revenue to surplus generation or grid export.
The announced framework allows up to 800 W production and 1,000 W installed capacity for self-consumption. DEDDIE's safety specifications and procedure are still pending.
For each scenario, monthly kWh used on site are based on the production and self-consumption percentage you enter, capped at the home's monthly use.
Monthly savings multiply those kWh by your entered price per kWh. Simple payback divides system cost by annual savings and excludes maintenance, fixed charges, taxes and financing.
This tool does not check installation permission or safety. Follow DEDDIE's specifications and digital process once published, and confirm an active installation certificate with a licensed installer.
This scenario assigns no credit to surplus production. It estimates only electricity used directly, as announced for balcony systems.
No. It depends on the production, self-consumption, electricity price and cost estimates you enter.
