Located in DFW, I have gotten multiple quotes from 5 companies for a variety of panels and trying to make a final decision. Would like some advice from those keeping up with current rates, AND whether holding out and waiting to install in the future is worth it at all. My opinion is that the tax credit may not get extended (for a second time) because prices are dropping so much. Combine that with a new $0.45cent rebate from our elec provider (which we are in a co-op, ugh...), means that it's a pretty good time to invest. Prices will probably drop another 25% on hardware the next 3-4 years, but install/permit/etc will not (possibly go up due to demand).
Best 3 options:
SunPower 360W X22-360-C-AC. 5.76kW system = $11,359 ($19,930 - $2592 rebate - $5979 tax credit) $3.46/W before, $1.97/W after incentives. 92% 25yr perf warranty. 25yr product. 22.2% efficient panel.
LG Neon R 365W LG365Q1C-A5. 5.84kW system = $11,271 ($19,856 - $2628 rebate - $5956 tax credit) $3.40/W before, $1.93/W after incentives. 87% 25yr perf warranty. 25yr product. 20.8% efficient.
Trina 300W TSM-DD05A.05 (II). 6kW system = $10,683 ($19,119 - $2700 rebate - $5735 tax credit) $3.19/W before, $1.78/W after incentives. 80% 25yr perf warranty, 10yr product. 18.3% efficient.
I know many here think SunPower is good but usually not worth the additional expense, but for less than $100 more than LG it seems like a good idea. Obviously there's the downside potential of SunPower going out of business and losing warranty, vs LG which will most likely not. Trina is definitely cheaper, but not THAT much for a considerable drop in performance warranty comparatively.
Since we're in Texas, I think the temp coef. maters for Summer months, and all 3 seem pretty good. Between .3-.4%/C-deg.
Also worth noting that our Co-Op does net metering by month only, with no pay-back, so we never want to produce more than our lowest month's bill throughout the year.
Thoughts? Hoping to make a decision pretty quickly.
