How much extra value can your solar power create?
Adjust your annual profile. DMEGC Control instantly shows how much more solar energy you can use at home, how much grid purchase you can avoid and the annual energy value this may create.
01 · Enter your annual energy use
Find these figures on your annual electricity statement or solar monitoring app. The starting values are examples; adjust them to your home.

Suggested starting size·10.24kWh
A first sizing guide using 60% of average daily generation and use, within the H02 range. Your installer should confirm this with your actual hourly profile and connection.

03 · Your indicative annual energy value
Compared with the same home without a battery. This is an energy-cost estimate before purchase, installation, maintenance and battery degradation — not net profit or a payback promise.

These bars show a price per kWh, not solar production or money earned. Electricity has a market price at night too; that does not mean your panels export solar power at night.

Negative electricity prices — storing solar energy may be more valuable than exporting it.

05 · Calculation basis & assumptions
Net metering ends on 1 January 2027. Solar used directly avoids purchase price, tax and supplier charges; export compensation depends on the contract and may turn negative under a dynamic contract.
*Indicative comparison based on a representative day, the selected storage capacity, 95% usable capacity, a 20% reserve and 96% efficiency in each charging and discharging direction. Actual costs depend on interval data, contract, export fees, tax, season, system settings and any zero-export control; no savings guarantee.
