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 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)

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

Doesn't work in my area yet so can't compare it to my actual system.
Ours was about $39000 in Oct of 19 before federal tax credit, local city rebate of about $3500 and a cash rebate thing from the company of about $1200. This says, for about the same size, $36000. I'd say it's a pretty accurate estimate.

For last year, we generated more than 16.28 MWh based on SolarEdge. There were a couple of weeks during August that our inverter stopped counting what was being generated and it took some time to get the guy out to do whatever tweaking needed doing. So that's about 65kWh more per day during that time. It's doing a good job.

It's not easy to tell exactly what's going on with respect to our electric bill because Austin Energy seemed to be using a system created in the 90s or something and we had been on bill averaging, I had a sizable credit on the account and the system could not distinguish between overpaid credits and solar credits. They figured it out eventually, but it wasn't very clear even then. We since got off the averaging and eventually allowed the overpayment to go away which took a while because no electric bill. :D Their solar reporting app isn't a whole lot better seeming than their utility billing system.

Thanks for the link. Very informative. I was surprised to see I only need about 3.5kW to cover 97% of my energy needs. I have to conduct a cost/benefit analysis to see if I want to cover 100% or more. I'm assuming the estimate is for grid-tied and does not include the cost of batteries and misc. items.

So looks like the average is $3 per Watt according to the original post of this thread? Yikes. In Peru the installation is not too expensive, but you get gouged on the products with the 18% sales tax, customs fees, shipping, etc. For a 6.4kwh array-based system, I'm looking at probably spending $16,500-$17,000 total including installation for an off-grid system. This includes Victron CerboGX, Touch 50, Multiplus 48/5000/70, SmartSolar 250/100 MPPT, cabinet, 4 Pylontech US3000 batteries.

If I were in the USA, I wouldn't even consider hiring someone to install. I'd just buy my own tools and watch youtube videos. Maybe pay a friend to help pass me the panels up on the roof. No way would I hire someone. If you DIY the install in the USA it turns out much cheaper than here in Peru, but when you pay someone else, the total price ends up about the same in both cases.

Thanks for sharing! Great to see what the roof coverage looks like around here. If only I could get it to realize our place is 4 connected townhouses and now 1 big 3,841 square foot roof :)

We are getting installation quotes for a small system with battery, mostly for grid down backup. The only one even close to our financial ballpark is Tesla.

My roof doesn't show on Google yet (too new), but I have $2800 in my system (including $250 of stuff I didn't end up using). Off Grid, non UL

~2000 watt of panels (9x250w)
~5kw of 24v battery (BYD 3kw x2)
~2000 watt inverter (LV2424)

Not sure how we are doing the $/watt calculation, but I think it was pretty affordable.
