The cost of a professionally installed PV system varies by location and by the amount of PV installed. With these numbers you might be able to better negotiate a price for your roof. Pricing is always changing over time and these tables were from 2018, so your mileage may vary.

So did you DYI or Buy? How was your $/watt? This information can help others as they set sail on the solar tides!

I don't actually have my system yet; should get the panels and microinverters before the end of the year, batteries in Feb.
Love the deal you guys struck! I'll update my system info as I go.

Love the deal you guys struck! I'll update my system info as I go.

I just got quotes from a couple of folks with the best reps that contacted me based on interest I expressed through the Solar Reviews site. The two I settled on deciding between were very close in price - I did no dealing at all - that was the cost offered by both out of the starting gate. Both gave me a lot of useful information too. It took 2 months from the time I decided to get estimates to having the system up and running. I had a time crunch driving the process for me because the Austin rebate was going to be lowered at the end of August. Having to deal with the city slowed the process a bit and I'd guess a rush of folks getting in on the deal before it was reduced also had the companies working overtime. The guys doing my install were here for 6 hours, left at 5:30 and were headed to do another install after ours and after having done 2 before ours in the same day!!

I'm excited to see how the system plays out after a few months of data. I also want to try to do a rogue battery back-up system on a part of our property that is on it's own circuit with its own panel after we see what we'll be generating with the grid tied system. I have a lot to learn before that's a reality though.

Is the price of the battery figured in to the price per watt for your system? What kind of battery are you getting and where from? That seems like a good deal to me.

Multiple quotes is smart. I did that too and pitted the vendors against each other to beat them down to a high price. But, I am in the average for my area; the problem they say is I'm a ways from civilization.

It's the new Enphase IQ8 AC battery. They're not actually out yet and already have a wait list. The $/W is just the solar cost so no where near the deal you guys got.

Hoping to see some of the DIY systems, bet they're coming in under $2/W.

I am getting a (30) Panasonic HIT 335W panel = 10,050 watt system installed with SolarEdge 10000H-US inverter on my home in Central Texas at a cost of $2.67/W (before federal credit)
Great price! I updated the table above with your numbers, thank you for sharing!

In 2000 I designed and installed my own system. Parts cost was $14,000 which included 1400 watts of panels @4.50 per watt, batteries @$2600 830a-hr. Total was: $10/w for the parts

This past week I found out a friend had contracted an installation in southern Utah for $22,000 for a 4.6kw panel array, Grid-tied. I told her, you should have talked to me first. That put her are $4.78/w - geez

I had a 11.7 kWh DC system installed in Aug 2018 near Pensacola FL. 39 x 300w Trina Allmax plus mono panels with the Enphase IQ7+ micro inverters for $28,665 ($20,065 after tax credit). That's the fully installed cash price (includes permits, fees, etc). It would have been more with financing. $2.45/W before tax credit, $1.715/W after tax credit.

First 12 months production (Sep 2018-Aug 2019) was 17,330 kWh. Almost all panels are facing SSW

What is this? I was told Will Prowse doesn't do installations, does he?

svetz, you can update your chart to change me from "Planning" to "11/19" for my system age. Did you get your system installed yet?

You can view my production levels by accessing my SolarEdge public site below. I plan to hold a party on the winter solstice to celebrate!

Approaching 800 kW-hr total production in a little over a month... Really happy with my HESolar installation.

Done! No, not yet. My contractor is trying my patience. Install is now set for early next year, so much their assurances it would happen in November and I wouldn't have any issues getting the 30% discount.

Why are you only getting 35 kWh/d with 10.5 kW of panels? Lot's of overcast days or is the solstice really taking that big of a bite?

Hah, hang in there... 26% (although not as good as 30%) is better than 0%...
