Hey everyone, just looking for a quick sanity check on this quote.

• Location: Cambridgeshire
• Panels: 16 x Astronergy 460W (7.36 kW total). Upgrades offered: LONGi 480W (+£22/panel) or AIKO 495W (+£42/panel).
• Inverter: LuxPower 10kW Hybrid (GEN 10K) - Single Phase. (no warranty specified)
• Battery: 1 x Fogstar Energy 5.12kWh Stackable (4.1kWh usable). Extra 5kWh blocks are £675 each. (6year warranty)
• Expected Generation: 7,154 kWh/year
• Total Cost: £7,850. Includes scaffolding (installer says it's higher than usual due to bridging a lower flat roof).
• Extras: No bird proofing included. SEG tariff is on me to set up.
• Company: Uk Solar

The installer swapped to the LuxPower 10kW because Solis is having stock issues right now.

I haven't asked for changes yet. Does £7.8k look reasonable for this setup? Also, is it worth paying the extra for the AIKO panels, or using that cash to add a second 5.12kWh battery module right away?

Thanks!
