2 less panels cost $3300 less?

[Overlook637]

Initial quote for 28 Q-Cell panels with enphase iq8h inverters and 2 Franklin batteries was $73,500. We found out that my power company (Georgia power) limits system size to 10kWH for net metering.

I asked for a new quote to stay at 10kWH. That would be two less panels. The cost decreased by $3300. My very limited knowledge tells me that a premium panel and most updated en phase should material cost less than $700 per panel and inverter. That’s $1400 in materials (not including brackets). With my limited knowledge- seams like they are charging a hefty installation cost.

Seeing the red flag. I checked the total system material costs.


I checked an online retailer. Two Franklin batteries, Franklin aGate controller. 28 Q-cell panels and 28 iq8h micro-investors totaled $41,000. Leaving me questioning $34,000 remaining costs for design, permits, installation, and warranty.


Any thoughts? Am I looking at this wrong approach?

Get several quotes and see how they compare. A lot can depend on location and site challenges. It also may be worth asking whether the10 kWh limit is based on inverter capacity or panel capacity.

Unfortunately, the quote will not go into a detailed list of all parts.

FWIW, my Q cell panels were about $1300-$1500 each installed. These went to a MPPT and a DC coupled battery charger. I gave a quote and bill, but not an itemized of how much the panels, inverter, and battery cost separately.

My numbers I use for fair market value for an installation is $15k for 5 kw of panels and $12k for 10 kWh of battery.

I don’t understand why the POCO limits you to 10kWh.
