Energy Cost & Payback — compare panel scenarios

Tool · 02 of 07

Step 1

Cold-room load

Required capacity

From the Load Calculator (Tool 1) — or enter your own.

System type

Drives default COP — cooler ≈ 2.5, freezer ≈ 1.6.

Step 2

Operation profile

Operating hours

h/day

Operating days

days/year

Load factor

Compressor doesn't run at 100%. Typical 60–80%.

COP (Scenario A)

—

Cold output ÷ electric input.

COP (Scenario B)

—

Better-insulated room ⟹ slightly higher COP (smaller compressor at the design point).

Step 3

Scenario A — current / baseline

Step 4

Scenario B — Izhar upgrade

Wall thickness B

Panel cost delta

Cost premium of B over A (panels + extra installation).

Step 5

Tariff & finance

Electricity tariff

Rs/kWh

WAPDA industrial ≈ 32, K-Electric ≈ 38.

Inflation

Annual cost is an estimate at the supplied tariff and assumed COP. Real-world cost varies with load profile, ambient swing, and equipment age. For a binding number, request a free site survey.
