7.4kW Gold Package_ SMA String Inverter Solar System


This system is designed to supply approximately 30kW of power on average throughout the day, this number will vary depending on your location, panel position, light conditions, and individual circumstances. During winter this number is less and in summer this figure will be higher due to the longer sunlight hours. It is important to get the power usage right for your individual circumstances. SAS is your solar system installation expert.


A 7.4kW system will usually require 20 x 370 Watt solar panels. This number varies according to which solar panels are selected, where they are positioned and other individual circumstances. This will be tailored individually to your needs. Larger systems available if required and can be customised to your home. If you have a growing family you may want to add a little bit more capacity to prepare you for power hungry kids who will always leave the lights on regardless of what you try and teach them! Is an electric car on the cards? If so, now may be a time to invest in a larger system to charge your car for free. See PANELS for more information.
