Yeh calculator residential, shop aur small commercial solar investment ka detailed cash-flow estimate banata hai. Self-consumed solar units ko grid tariff aur exported units ko alag credit rate par value karta hai.

Simple aur discounted payback mein antar

Simple payback nominal yearly cash savings se investment recover hone ka samay dikhata hai. Discounted payback future money ki present value ko discount rate se adjust karta hai, isliye aam taur par zyada hota hai.

Solar Payback Calculator FAQs

Self-consumption percentage kya hai?

Solar generation ka jo hissa ghar ya business mein turant use hota hai, woh self-consumption hai. Baaki export/net-meter credit mein ja sakta hai.

IRR aur NPV kya batate hain?

NPV future cash flows ki present value minus investment hai. IRR woh discount rate hai jahan NPV lagbhag zero hota hai. Dono investment comparison mein useful hain.

Loan EMI payback mein include hai?

Calculator EMI alag dikhata hai. Project payback asset-level net investment aur operating cash flow par based hai, jisse cash aur loan options compare kiye ja saken.

Inverter replacement kyon include hai?

Long analysis period mein inverter replacement ho sakta hai. Entered year mein replacement cost cash flow se subtract hoti hai.

Kya mobile PDF chalegi?

Haan. Button Android print service open nahi karta; direct BijliBee branded single-page A4 PDF download karta hai.
