Using the same three 6 volt, 3. 0 amp panels from above, we can see that when these pv panels are connected together in series, the array will produce an output voltage of 18 Volts (6 + 6 + 6) at 3. 0 Amperes, giving 54 Watts (volts x amps) at full sun.

4 Divide system size (in watts) by panel wattage — typically 420W in 2026 Annual consumption: 10,200 kWh (from Alectra 12-month statement) Ontario specific yield (Mississauga): ~1,150 kWh/kW/year System size needed: 10,200 ÷ 1,150 = 8. 87 kW Panel wattage (Trina / Longi Tier-1): 420W.

In this tutorial, I'll show you how to wire solar panels in series and how to wire them in parallel. Once we've got that covered, I'll also explain the difference between these two configurations in Voltage (Volts) and Current (Amps) and provide a real-life example.
