Power Calculation & System Capacity Selection
On-Grid Solar Calculator
Enter average consumption (units/day). This estimates the kW needed to target near-zero bill with net-metering.
Assumption: 1 kW ≈ 3.5 units/day average (safe sizing). Actual varies with shading/roof direction.
Off-Grid Package Calculator
Enter your average electricity usage in Units per day. We’ll recommend the best off-grid package from our chart.
Disclaimer: This calculator selects packages based on your usage range. Final sizing depends on roof condition and appliance peak load.
Zayan Solar Off-Grid / Hybrid Packages
Choose your package based on your daily electricity usage (Units per day from your KSEB bill).
| Package Name | Daily Usage | Solar Size | Battery Pack (LFP) | Battery Energy | Inverter |
|---|---|---|---|---|---|
| Starter | 0–2 units/day | 1 kW | ~25V / 105Ah (24V class) | 2.6 kWh | 2 kW |
| Smart | 2–5 units/day | 3 kW | ~51V / 105Ah (48V class) | 5.3 kWh | 3 kW |
| Family | 5–8 units/day | 4 kW | ~76V / 105Ah (72V class) | 8.0 kWh | 5 kW |
| Premium | 8–10 units/day | 6 kW | ~102V / 105Ah (96V class) | 10.7 kWh | 8 kW |
Note: Final sizing depends on appliance load, rooftop condition, and site inspection.

✅ മീറ്റർ റീഡിംഗ് എങ്ങനെ വായിക്കാം
KSEB ബില്ലിൽ കാണുന്ന Last Readingയും New Readingയും ഉപയോഗിച്ച് 2 മാസം ഉപയോഗിച്ച യൂണിറ്റ് കണ്ടെത്താം.
📌 Formula
👉 New Reading − Last Reading = 2 മാസം ഉപയോഗിച്ച യൂണിറ്റ്
✅ ഉദാഹരണം
Last Reading = 12500
New Reading = 13040
👉 13040 − 12500 = 540 യൂണിറ്റ്
അതാണ് 2 മാസത്തെ വൈദ്യുതി ഉപയോഗം.
✅ ദിവസം എത്ര യൂണിറ്റ് ഉപയോഗിക്കുന്നു എന്ന് കണ്ടെത്താം
ബിൽ സാധാരണയായി 60 ദിവസം ആയിരിക്കും.
👉 Daily Units = Total Units ÷ Days
👉 540 ÷ 60 = 9 യൂണിറ്റ് per day
✅ ഇത് ഉപയോഗിച്ച് സോളാർ സൈസ് കണ്ടെത്താം
👉 1 kW സോളാർ ≈ 4 യൂണിറ്റ് per day
👉 Daily Use = 9 യൂണിറ്റ്
👉 Solar Needed ≈ 9 ÷ 4 = 2.25 kW
👉 Recommended Package = 3 kW Solar
✅ ചുരുക്കം (Customer Friendly)
👉 New Reading − Last Reading = Total Units
👉 Total Units ÷ Days = Daily Units
👉 Daily Units ÷ 4 = Solar kW

How to Calculate Daily Electricity Usage from KSEB Bill
Your electricity bill usually shows Last Reading and New Reading.
📌 Formula
New Reading − Last Reading = Total Units Used (for 2 months)
✅ Example
Last Reading = 12,500
New Reading = 13,040
👉 13,040 − 12,500 = 540 Units
This means you used 540 units in 2 months.
✅ Find Daily Usage
Most KSEB bills are for about 60 days.
👉 Daily Units = Total Units ÷ Number of Days
👉 540 ÷ 60 = 9 Units per Day
So your home uses about 9 units per day.
✅ How to Estimate Solar Size
In Kerala average:
👉 1 kW Solar ≈ 4 Units per Day
So:
👉 Solar Needed = Daily Units ÷ 4
Example:
Daily Use = 9 Units
Solar Needed ≈ 9 ÷ 4 = 2.25 kW
