How much does an inverter cost?

Inverter type has the largest impact on installed system cost, with use of string inverters resulting in $1.61/WDC and use of microinverters resulting in $1.92/WDC.

How much does an energy storage system cost?

The modeled $/kWh costs for 600-kW Li-ion energy storage systems vary from $469/kWh (4-hour duration) to $2,167/kWh (0.5-hour duration). The battery cost accounts for 41% of total system cost in the 4-hour system, but only 11% in the 0.5-hour system.

How many kW can a single phase inverter install?

For Australian properties with single phase electricity (that's most of us) you can usually install up to 6.5kW of panels, with a 5kW inverter, and often you'll be able to get as much as a 10kW inverter. US households are not often restricted in system size by the power company, and the usual system size is between 10-20kW.

How do I get a price estimate for a solar system?

Use the simple Solar Calculator to get an instant price estimate for solar and batteries. It is important to note, that you neither want to pay too much nor too little for a solar system. It might sound strange that you would not want to pay too little but think about it as if you were going out to dinner.

How many kW can an inverter run?

The system size is usually limited by inverter output not the nominal panel output, so you can install a larger panel array, but you may be limited to a 5kW inverter. In some areas, you are allowed up to 10kW on a single-phase connection if you add battery storage. Unfortunately, in some rural areas, you might be limited to as little as 2 or 3kW.

How much does a 3 kW storage system cost?

As demonstrated above, the kit for a 3-kW/6-kWh storage system costs approximately $4,200–$4,600, with a total installed cost of $11,823 (DC-coupled) to $12,287 (AC-coupled). The kit for a 5-kW/20-kWh storage system costs approximately $10,400–$10,800, with a total installed cost of $21,471 (DC-coupled) to $22,041 (AC-coupled).
