The most accurate way is to manually input your particular appliances, including Wattage and time of use. Alternatively you can use appliances provided below.Example: 3 x 100 watt incandescent bulb x 4 hours/day = 1200 Total Max Watt-Hours/Day. Therefore 1200 W=1.2 kWh a day of battery storage would be required.
You can forward the results to your email for later use by using the form below. If you wish to be contacted to receive a quote, tick (I would like to be contacted by Quebec Solar Team field) or call us directly at 514.836.9876
