Solar System Planning
Estimate your home or business energy requirements before requesting a professional solar design.
Start with your electricity bill
Choose a clear photo of your GPL bill. We’ll try to find your monthly kWh. Confirm the numbers before calculating, or enter them yourself.
The photo is read on your device. No account or API key is needed.
Check these figures against your bill before using the estimate:
If a number looks wrong, correct it here. Bill amounts in GYD are not kWh.
Advanced settings (optional)
Enter kWh from your GPL bill when available. The daily figure is then calculated from monthly kWh divided by billing days. A bill amount in GYD alone cannot determine kWh without tariff details.
Preliminary energy sizing only. No inverter, battery, panel string, breaker, surge protector, cable, installation layout or grid interconnection is approved by this tool. A qualified solar/electrical professional must verify site conditions and design.
