Solar PV engineering from site assessment to interconnection, covering rooftop, ground-mount, carport, and BIPV for residential and commercial projects across Canada.

How many panels do I need for my home?

A typical Ontario home (1,000 kWh/month) needs a 8–10 kW system (18–23 panels at 445W). The exact number depends on your roof orientation, shading, and electricity consumption patterns. Our free solar study calculates this precisely for your address.

Key Deliverables

• PVsyst energy yield simulation (P50/P90)
• Single-line diagram (SLD), P.Eng stamped
• Module layout drawings (AutoCAD)
• String sizing and inverter selection report
• Structural attachment detail review

What is a DC/AC ratio and why does it matter?

The DC/AC ratio is the installed panel capacity divided by the inverter AC output. A ratio of 1.15–1.25 maximizes annual energy harvest by allowing panels to clip only during peak hours while capturing more energy in morning/evening. Over-sizing reduces cost per kWh.
