What Size System Do You Need?
| Daily Usage | System Size | Panels | Typical Home |
|---|---|---|---|
| Low (10-15 kWh/day) | 5kW | 10-12 | Apartment, 1-2 people |
| Medium (20-30 kWh/day) | 6.6kW | 12-15 | Average home, 3-4 people |
| High (30-45 kWh/day) | 10kW | 18-22 | Large family, pool |
| Very High (45+ kWh/day) | 13kW+ | 24-30 | Large home, EV, multiple AC |
Tip: Its often worth going slightly larger if roof space allows. The cost per kW decreases with larger systems, and youll have room for future electricity needs (EV, battery, etc.).
Red Flags to Watch For
warningHigh-pressure sales tactics
Legitimate installers dont pressure you to sign today or offer one-day-only deals.
warningUnusually low quotes
If a quote is significantly cheaper, check the equipment quality. Cheap systems often use lower-tier components.
warningLarge upfront deposits
Reputable installers typically ask for 10-20% deposit, not 50%+. Full payment should only be after installation.
warningVague equipment details
The quote should clearly specify panel brand, model, inverter brand, and all components.
warningNo CEC accreditation
Without CEC accreditation, you wont receive STCs (government rebate). This is non-negotiable.
warningDoor-to-door sales
Be cautious of unsolicited door knockers. They often have high-pressure tactics and inflated prices.
