Based on this thread (https://www.reddit.com/r/solar/comments/15c6wqf/solar_quote_in_va_42_panels_19097_kwh_production/) that I posted recently, the same vendor (#2) came back with another option that’s a lower price point but based on a 100% SunPower solution:
SunPower Solution
15.84 kW system, 19,202 kWh production
44 SunPower SPR-X22-360-E-AC (240V) panels w/integrated microinverters and Critter Guard.
Cost/Watt $3.20
Warranty: SunPower 25 years
Gross System Price $50,688 (cash price, before tax credit, SREC)
How does this look?
Looking at this link (https://www.consumeraffairs.com/solar-energy/how-much-do-solar-panels-cost.html), it says the average price of solar in VA (I’m in NoVA) is $2.75 so this $50,688 price is a bit higher than what I had expected but I assume that’s because SunPower commands a price premium over the other brands (e.g. SEG, Trina, REC). Is that the correct assumption? The installer is not only SunPower certified (in NoVA) but also the preferred/vetted solar vendor by my utility co.
If I’m going solely on a cost perspective, then the lower cost competing options would be:
Vendor #1 – Trina/EnPhase System
19,097 kWh (production), 16.38 kWh (system)
42 Trina (Vertex S, 390; TSM-DE09C.07) with EnPhase IQ8+ microinveters and Critter Guard.
Warranty: 30 years (extended from 25 years)
Gross System Price $45,817 (cash price, before tax credit, SREC)
Vendor #2 – SEG Solar SIV Series/EnPhase System
16.61 kW system, 19,072 kWh production
41 SEG-405-BMD-HV panels with 41 EnPhase IQ8PLUS-72-2-US microinverters and Critter Guard.
Cost/Watt $2.74
Warranty: SEG 15 years
Gross System Price $45,498 (cash price, before tax credits, SREC)
My understanding is that efficiency factors plays a bigger role than just price alone and that the SunPower are more efficient than the Trinia and/or SEG in the grand scheme of things, so one can’t just go on price alone?
