Review Solar Self-Consumption and Undiscounted Payback

Review a 365-day solar self-consumption model, then see its flat annual cash flows and undiscounted payback schedule. Download both reports and the source.

• Use JSON with quoted fields:arrayKilowatts,sunHoursPerDay,lossPercent,pricePerKwh,selfConsumedPercent. The solar calculation covers365days. Enter an initial outlay,annual operating cost and1-100whole years in the same currency. Each year repeats the actual modeled self-consumed electricity value minus the supplied annual operating cost. Discount is fixed at0. Review the original full schedule:the first modeled recovery crossing uses cumulative annual cash flows and within-year interpolation;null means recovery was not reached within your horizon. This flat model excludes weather lookup,export revenue,degradation,inflation,tax,financing,replacements and salvage. It is not an investment recommendation or guaranteed recovery. Both reports,raw source and actual arguments remain in the download. Invalid downstream assumptions retain the full solar checkpoint.
• One strict UTF8JSON object exactly five unique STRING keys:arrayKilowatts,sunHoursPerDay,lossPercent,pricePerKwh,selfConsumedPercent. Each single-line<=128UTF16units;source8192UTF8bytes/4096UTF16units/4097lines/strict6nodes,safe255unit1020byte filename. RawBOM/CRLF/order/whitespace preserved. Original capacity0..1e12kWp,equivalent fullsun0..24hours/day,loss0..100percent,avoidedprice0..1e12,selfconsumedshare0..100percent. Fixed explicit original days365 is one model year,not a weather forecast.
• Original arrayRatedKwp,sunhours,lossPercent=Number(loss)/100*100,days365,avoidedPrice,selfConsumedPercent=Number(self)/100*100. idealDaily=capacity*sun;netDaily=idealDaily*(1-lossPercent/100);period=netDaily*365;selfConsumed=period*selfConsumedPercent/100;exported=period-selfConsumed;modelAvoidedElectricityCost=selfConsumed*price. Preserve all12originalfields and original binary64 operation order. No weather/location/model lookup,export tariff or clipping/performance guarantee.
• Read actual complete original solar report modelAvoidedElectricityCost for365days. Parse supplied annual operating cost with unchanged original nonnegative helper0..1e12,and horizon with unchanged original integer helper1..100. annualNetCashFlow=actual native avoidedCost-native Number operatingCost,one binary64 subtraction. Repeat that same native number exactly horizon times in a JSON numeric array;JSON.stringify gives original flows argument. Pass supplied initial outlay and fixed rate0 to original payback. Record actual avoidedCost,operatingCost,annualNetCashFlow,horizonYears,365days,flat repetition,end-year convention,fixed zero discount and actual arguments. No rounding/clamp/recomputed energy/absolutevalue/stream override. Projection-domain failures keep completeCP without invoking payback;valid projection whose flows exceed original signed scalar1e12 bounds refuses original payback and keepsCP.
• Three explicit supplied controls:initial outlay10000,annual operating cost100,horizon20whole years (1..100). Same user-chosen currency as avoided electricity price. Fixed annual365-day production/flat annual benefit and fixed original discount0. No exported-energy revenue,growth/degradation,price inflation,taxes,grants,financing,replacements,salvage or midyear convention inferred. Original standalone controls/defaults unchanged.
• Original positive initial outlay1e-12..1e12;each signed numeric cashflow-1e12..1e12,1..100flows here. Fixed original rate0 yields discountFactor1;each end-year presentValue=cashFlow/1**year,so original simple/discounted streams match. Preserve original sequential binary64 cumulative additions starting at-initial and original first nonnegative crossing interpolation i + -opening/cashFlow;null if no recovery in supplied horizon. No simplified initial/annualNet quotient substituting for original cumulative interpolation. All8top-level original fields plus full5fields per source-order schedule row retained,including nulls/interpolation text/final balances.
