You have 30kW of panels? That's a large system. Most people cna't fit that many. The more panels you get the lower the price gets per kWh.

- gibybo 8y agoI have found it to be surprisingly proportional. I'm sure it gets slightly cheaper per kwh with large systems, but not by a lot. I had quotes around $2.5/watt for 9 kW systems and $2.5/watt for 15 kW systems.
- driverdan 8y agoFair point since $2.5/W is over two thirds installation. If you buy the panels and install them yourself you'd save a lot of money.
