**How many solar panels do I need for 1000 kWh per month?** One solar panel on your roof will produce an average of 1,350 watts or 1.35 kWh per day. 1.35 X 30 = 40.5 kWh per month (assuming a 30-day month). You need a solar panel system that produces 1,000 kWh per month. 1000 kWh / 40.5 kWh = **24.69 solar panels**.
