شما می توانید محاسبات خود را با استفاده از TypeScript ایجاد کنید. کد پایین این صفحه به شما کمک می کند تا تعیین کنید که آیا نصب پنل های خورشیدی در درازمدت ارزان تر است یا پرداخت قبض برق خود را همانطور که هست ادامه دهید.
در اینجا یک تفکیک سطح بالا از نحوه تعیین هزینه های پنل خورشیدی توسط کد ارائه شده است.
بخش 1: نیازهای سیستم و راه اندازی
ابتدا میزان مصرف برق فعلی و قبض های خود را تعریف کنید:
هر ماه چقدر برق مصرف می کنید؟ ( monthlyKwhEnergyConsumption )
هزینه آن برق چقدر است؟ ( energyCostPerKwh )
بعد، برنامه های منظومه شمسی خود را وارد کنید:
چند تا پنل؟ ( panelsCount )
پنل ها چقدر قدرتمند هستند؟ ( panelCapacityWatts )
هزینه نصب چقدر است؟ ( installationCostPerWatt )
آیا تخفیفی در سیستم وجود دارد؟ ( solarIncentives )
بخش 2: محاسبات
بر اساس مقادیر وارد شده، کد محاسبه می کند:
yearlyProductionAcKwh : کل برق سالانه ای که پنل های خورشیدی شما می توانند تولید کنند.
totalCostWithSolar : هزینه برق طی سالیان متمادی با پنل های خورشیدی.
totalCostWithoutSolar : هزینه برق طی سالیان متمادی بدون پنل های خورشیدی.
بخش 3: نتایج
کد همچنین موارد زیر را به شما می گوید:
savings : تفاوت بین هزینه با و بدون پانل های خورشیدی.
breakEvenYear : چند سال باقی مانده تا هزینه پنل های خورشیدی برابر با صرفه جویی در مصرف برق باشد.

The code at the bottom of\nthis page helps you determine whether it's cheaper in the long run to install\nsolar panels or continue paying your electricity bill as is.\n\nHere's a high-level breakdown of how the code determines solar panel costs.\n\nPart 1: System needs and setup\n------------------------------\n\nFirst, define your current electricity usage and bills:\n\n- How much electricity do you use each month? (`monthlyKwhEnergyConsumption`)\n- How much does that electricity cost? (`energyCostPerKwh`)\n\nNext, enter your solar system plans:\n\n- How many panels? (`panelsCount`)\n- How powerful are the panels? (`panelCapacityWatts`)\n- How much does installation cost? (`installationCostPerWatt`)\n- Any discounts on the system? (`solarIncentives`)\n\nPart 2: Calculations\n--------------------\n\nBased on the inputted values, the code calculates:\n\n- `yearlyProductionAcKwh`: The total annual electricity your solar panels can generate.\n- `totalCostWithSolar`: The cost of electricity over many years **with** solar panels.\n- `totalCostWithoutSolar`: The cost of electricity over many years **without** solar panels.\n\nPart 3: Results\n---------------\n\nThe code also tells you the following:\n\n- `savings`: The difference between the cost with and without solar panels.\n- `breakEvenYear`: How many years until the cost of solar panels equals the savings on electricity.\n\nExample code\n------------\n\n\n```typescript\n// Solar configuration, from buildingInsights.solarPotential.solarPanelConfigs\nlet panelsCount = 20;\nlet yearlyEnergyDcKwh = 12000;\n\n// Basic settings\nlet monthlyAverageEnergyBill: number = 300;\nlet energyCostPerKwh = 0.31;\nlet panelCapacityWatts = 400;\nlet solarIncentives: number = 7000;\nlet installationCostPerWatt: number = 4.0;\nlet installationLifeSpan: number = 20;\n\n// Advanced settings\nlet dcToAcDerate = 0.85;\nlet efficiencyDepreciationFactor = 0.995;\nlet costIncreaseFactor = 1.022;\nlet discountRate = 1.04;\n\n// Solar installation\nlet installationSizeKw: number = (panelsCount * panelCapacityWatts) / 1000;\nlet installationCostTotal: number = installationCostPerWatt * installationSizeKw * 1000;\n\n// Energy consumption\nlet monthlyKwhEnergyConsumption: number = monthlyAverageEnergyBill / energyCostPerKwh;\nlet yearlyKwhEnergyConsumption: number = monthlyKwhEnergyConsumption * 12;\n\n// Energy produced for installation life span\nlet initialAcKwhPerYear: number = yearlyEnergyDcKwh * dcToAcDerate;\nlet yearlyProductionAcKwh: number[] = [...Array(installationLifeSpan).keys()].map(\n (year) =\u003e initialAcKwhPerYear * efficiencyDepreciationFactor ** year,\n);\n\n// Cost with solar for installation life span\nlet yearlyUtilityBillEstimates: number[] = yearlyProductionAcKwh.map(\n (yearlyKwhEnergyProduced, year) =\u003e {\n const billEnergyKwh = yearlyKwhEnergyConsumption - yearlyKwhEnergyProduced;\n const billEstimate =\n (billEnergyKwh * energyCostPerKwh * costIncreaseFactor ** year) / discountRate ** year;\n return Math.max(billEstimate, 0); // bill cannot be negative\n },\n);\nlet remainingLifetimeUtilityBill: number = yearlyUtilityBillEstimates.reduce((x, y) =\u003e x + y, 0);\nlet totalCostWithSolar: number =\n installationCostTotal + remainingLifetimeUtilityBill - solarIncentives;\nconsole.log(`Cost with solar: $${totalCostWithSolar.toFixed(2)}`);\n\n// Cost without solar for installation life span\nlet yearlyCostWithoutSolar: number[] = [...Array(installationLifeSpan).keys()].map(\n (year) =\u003e (monthlyAverageEnergyBill * 12 * costIncreaseFactor ** year) / discountRate ** year,\n);\nlet totalCostWithoutSolar: number = yearlyCostWithoutSolar.reduce((x, y) =\u003e x + y, 0);\nconsole.log(`Cost without solar: $${totalCostWithoutSolar.toFixed(2)}`);\n\n// Savings with solar for installation life span\nlet savings: number = totalCostWithoutSolar - totalCostWithSolar;\nconsole.log(`Savings: $${savings.toFixed(2)} in ${installationLifeSpan} years`);https://github.com/googlemaps-samples/js-solar-potential/blob/1892b99f1a8e4d7254c8b4426cfe9c8d492108b2/src/routes/sections/SolarPotentialSection.svelte#L53-L108\n```\n| **Note:** Read the [guide](/maps/documentation/javascript/using-typescript) on using TypeScript and Google Maps.\n\n\u003cbr /\u003e"]]
