Renewable Generation Value

Split entered generation into on-site use and export. Show export income separately from avoided grid purchases.

Use renewable generation value →

Battery Runtime Scenario

Apply usable share and one-way conversion efficiency to nominal DC energy, then divide available AC energy by a constant AC load.

Use battery runtime scenario →

Battery Arbitrage Scenario

Price one supplied charge/discharge cycle after round-trip loss and a user-stated degradation allowance, then extend it over counted cycles.

Use battery arbitrage scenario →

Solar Simple Payback

Calculate annual value from supplied self-use and export quantities, then compare positive net savings with net installed cost.

Before you use these calculations

Use generation over a clearly defined period and the matching installed capacity.

Separate export income from avoided electricity purchases.

Constant scenarios do not model weather, degradation, curtailment or a full project appraisal.

Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
