Rising Energy Costs Are Eating Your Margins
Solar PV lets you lock in your energy cost for 25+ years. Every kilowatt-hour you generate yourself is one you do not buy from KPLC.

How Solar Reduces Your KPLC Bill
Every unit of electricity your solar panels generate is a unit you don't buy from KPLC. If your panels produce 10,000 kWh in a month and you consume 10,000 kWh, your KPLC bill for energy drops to nearly zero. You still pay fixed charges, but the big variable cost — the kWh — is slashed.
Your new KPLC bill = Old bill − solar kWh generated × KPLC rate
Three Types of Solar Systems
On-Grid (Solar Only)
Solar panels + inverter. No battery. Solar power offsets your KPLC consumption during the day. At night, you buy from KPLC as usual.
✓ Lowest cost
Best if most of your consumption is during daytime hours (offices, factories, shops open 8am–5pm).
⚠ Net metering is not yet fully implemented in Kenya — it is being rolled out in stages in future 100MW lots. Until then, excess daytime solar cannot be exported to KPLC.
Hybrid (Solar + Battery)
Solar panels + inverter + battery. Excess daytime solar charges the battery. At night, you use stored solar instead of buying from KPLC.
✓ Best overall value
Best if you have significant evening/night load or want backup during KPLC outages. Also ideal if your daytime load is low but nighttime is high.
The battery lets you use your solar 24/7 instead of only during sunshine hours.
Off-Grid (Fully Independent)
Solar panels + large battery + inverter + genset backup. No KPLC connection at all. You generate and store all your own power.
✓ Total independence
Best if you're in a remote area with unreliable or no grid, or KPLC connection fees are very high. A diesel/petrol genset covers extended cloudy periods.
⚠ Most expensive — needs a large battery bank and backup generator.
Which System Is Right for You?
On-Grid
Reliable KPLC grid + most consumption during daytime (offices, retail, factories)
Hybrid
Unreliable grid, significant evening/night usage, or want backup during outages
Off-Grid
Remote location, no grid access, or KPLC connection costs are prohibitive

Fetch Your Latest Consumption Data
Technolectric retrieves your KPLC consumption data using your meter number to auto-fill all calculator fields. We are not affiliated with Kenya Power. Your data is not stored.
Found on your KPLC bill as "Max Demand kVA". Enter 0 if unknown.
Hybrid Inverter Sizing
During a grid outage, should the inverter handle your full load (all equipment running at once) or only essential loads (critical equipment only)?
Full load sizes the inverter to 130% of max kVA demand. Essential loads uses solar-array-based sizing.
