Solar inverter DC-AC ratio
User-supplied measurements and assumptions; DC nameplate=module count×module STC power; DC/AC=DC nameplate/inverter AC rating.
Renewable energy project scenarios ↗Solar clipping from power trace
User-supplied measurements and assumptions; Convert available DC by constant efficiency, cap AC output each interval and integrate excess; no detailed inverter curve.
Renewable energy project scenarios ↗Solar shading time-weighted loss
User-supplied measurements and assumptions; Time-weighted multiplicative shade factors applied to supplied unshaded powers; no electrical mismatch model.
Renewable energy project scenarios ↗Solar row spacing geometry
User-supplied measurements and assumptions; Rows perpendicular to sun azimuth on level ground: pitch=Lcos(tilt)+Lsin(tilt)/tan(altitude)+allowance.
Renewable energy project scenarios ↗Solar polygon grid module layout
User-supplied measurements and assumptions; Compare two axis-aligned grid orientations anchored to polygon bounding-box minimum; keep rectangles wholly inside usable polygon and outside supplied exclusions.
Renewable energy project scenarios ↗Solar bifacial gain scenario
User-supplied measurements and assumptions; Front energy × (1+rear gain) × (1−additional losses); all gain factors supplied, no irradiance geometry model.
Renewable energy project scenarios ↗Solar degradation lifetime output
User-supplied measurements and assumptions; First year is supplied; apply each listed degradation sequentially to produce following year output.
Renewable energy project scenarios ↗Solar export-limit control simulation
User-supplied measurements and assumptions; Deterministic self-consumption dispatch: serve load, store surplus, discharge for deficits, export to cap, curtail rest; constant separate one-way efficiencies.
Renewable energy project scenarios ↗Solar tariff change cashflow
User-supplied measurements and assumptions; Net interval imports/exports valued at supplied tariffs; fixed charge added once; no net-metering carryover.
Renewable energy project scenarios ↗Solar maintenance revenue loss
User-supplied measurements and assumptions; Apply supplied outage fractions to aligned production profile and value each interval.
Renewable energy project scenarios ↗Solar performance ratio audit
User-supplied measurements and assumptions; PR=(AC energy/DC nameplate)/(POA irradiation/STC irradiance); boundary explicitly uses AC energy and DC rating.
Renewable energy project scenarios ↗Solar weather-normalized comparison
User-supplied measurements and assumptions; Linear irradiation normalization only; temperature, curtailment and availability not corrected.
Renewable energy project scenarios ↗Solar cable route material budget
User-supplied measurements and assumptions; Route lengths × conductors × allowance; specified connector pairs counted independently.
Renewable energy project scenarios ↗Wind turbine power-curve yield
User-supplied measurements and assumptions; Interpolate supplied turbine power curve at wind bins and weight by bin hours; all queried bins must lie inside curve.
Renewable energy project scenarios ↗Wind shear height extrapolation
User-supplied measurements and assumptions; Power-law shear Utarget=Ureference(ztarget/zreference)^α; user supplies representative α.
Renewable energy project scenarios ↗Wind measured capacity and availability factors
User-supplied measurements and assumptions; Energy/(rated power×period hours); availability supplied separately; available-hour factor is not a resource forecast.
Renewable energy project scenarios ↗Wind farm wake-loss budget
User-supplied measurements and assumptions; Sequential multiplicative wake, electrical and availability factors; factors are retained-output fractions.
Renewable energy project scenarios ↗Small hydro site power worksheet
User-supplied measurements and assumptions; Hydraulic P=ρgQH; multiply by supplied turbine and generator efficiencies, with net head already accounting losses.
Renewable energy project scenarios ↗Small hydro constant-efficiency seasonal yield
User-supplied measurements and assumptions; Apply supplied operating limits to flow-duration bins; integrate ρgQHη with constant efficiency and head.
Renewable energy project scenarios ↗Renewable curtailment compensation
User-supplied measurements and assumptions; Sum eligible curtailed energy × user-supplied contractual rates; apply entered cap.
Renewable energy project scenarios ↗Renewable certificate inventory
User-supplied measurements and assumptions; Only complete energy units support certificates; separate issuable from already-issued unretired inventory.
Renewable energy project scenarios ↗Renewable annual discounted payback
User-supplied measurements and assumptions; Year-end discounted cashflows with final residual; fractional payback linearly allocates the crossing year’s discounted cashflow.
Renewable energy project scenarios ↗Renewable repowering scenario
User-supplied measurements and assumptions; Compare constant old/new annual yields; deduct first-year lost generation and capital cost; no escalation or discounting.
Renewable energy project scenarios ↗Community energy proportional payout
User-supplied measurements and assumptions; Distribute net income proportionally to supplied agreed weights; no currency rounding reconciliation or governance rule inferred.
