9.9 kw Solar Panel System

Amongst various residential and commercial systems, a 9.9 kW solar panel system is a staple choice. This solar power system can generate an average of 33kWh from solar energy on a daily basis. It is generally attached with an 8kW or 10kW Inverter and 27 to 33 solar panels. 

Is 9.9kW Solar System perfect for you?   

In order to determine if a 9.9kW solar system is right for you, we first need to find out how much electricity you require on average. In your most recent quarterly power bill, you will find this information readily available. If your average daily usage falls somewhere around 32 to 40kWh, installing 9.9kW solar panels on your roof can be a safe choice for you. This type of solar power system would generate enough power to meet your electricity requirements on a daily basis and would also allow you to increase your consumption if required.

You should audit your current electricity consumption habits to maximize the return from your solar system. Identify activities that consume a substantial amount of power (washing machines, dishwashers, dryers, etc) and make sure these appliances are only used during daylight hours when the sun is out. Always remember that never use all the heavy appliances at the same time. Ensure that the solar power system can meet all your electricity requirements by spreading out the time.
