That is final cost after all rebates. Contract price to RGS is $26,554.QueenBee said:JasonA said:Final costs for 8.11kw (DC) 7.21(AC- annual output of 13,619kwh) came out to $18,875.
Please quote the cost paid to the installer and then if inclined the cost after the various rebates I assume a price of $2.33 installed is after federal and state rebates.

My system is too small to have a worthwhile ROI. My view is that "other people buy less useful toys, do they not?" I consider the cost of the solar array part of the cost of my EV, except that it should last long enough to power the next EV as well.Cheezmo said:My electric rates get real low in the winter (4.2c/kWh anyone?) so the ROI is kind of tough but I basically prepaid 20 years worth of electricity at less than 7c/kWh so it has the potential to pay for itself.
QueenBee said:I think that has to be a new low that I've seen! $3.27 a watt installed, nice job!

You mean lowest in CA? Mine was $ .91/W installed.
Remember that it'll be $19k after all is said and done...QueenBee said:LEAFfan said:QueenBee said:I think that has to be a new low that I've seen! $3.27 a watt installed, nice job!

No, I mean lowest cost as in how much was paid to the installer by you, taxpayers, utility customers, etc. Please quote the cost paid to the installer not just the after federal, state, local rebates cost which will vary widely depending on location.
JasonA said:$2.34 will be final after federal (have 5 years to deduct).. but the wife wants a Tesla... so.... :shock:
And I'm thinking about a RAV4ev... so those deductions have to start flying!

Exactly. No one asks what the "payback time" is for leather seats or premium audio, do they? Especially if you enjoy learning about and "monkeying with" your solar setup (aside from the fact that it does at least partially pay for itself), it is worth it.dgpcolorado said:My system is too small to have a worthwhile ROI.

That matches our experience exactly. The only real hitch we had was that our inspector would not improve the installation without the addition of an external lockable disconnect. He agreed with me that this is not an NEC requirement, but he said our electricity coop would not allow net metering without it. He described the electricity provider as "his customer" and that his hands were tied. The change ended up costing me about $250 in parts and about $700 in lost electricity production due to difficulties in getting the work done.QueenBee said:Most jurisdictions allow the home owner to do their own electrical work so there generally is no problem with that. If the jurisdiction doesn't finding a electrician who is willing to do the AC wiring in an Enphase micro inverter setup should be fairly easy and not too expensive. The vast majority of the manufacturers don't require a specific certification to install for the warranty to be valid. Designing a micro inverter system is very straightforward. Iron Ridge provides a good calculator for doing the engineering on roof load, etc. One of the more challenging pieces is finding the trusses and installing the mounts/flashing. I did both phases of my system DIY (with the help of family that are contractors) and am helping a handful of others do the same. The materials are right around $2 per watt. A few are LEAF owners from here and then most recently someone who lives in my city saw my permit and contacted me.surfingslovak said:While on the topic, I would love to hear about the feasibility and regulatory requirements for self-installed systems.

Anyway, it's very doable for someone with AC wiring skills, basic mechanical skills and who is comfortable working with roofing, flashing, finding trusses and has a friend or two to help lugging everything to the roof
Perhaps, but I will contend that most people will not be willing to spend many thousands of dollars to install and maintain a system which they may find to be aesthetically unpleasing, will eventually require maintenance and/or repair and provides no tangible benefits over the system which is currently in place. I will further contend that a short payback time is the ONLY reason most people would consider purchasing a PV system. in other words, it is a financial investment for them, pure and simple.mbender said:Exactly.

Valdemar said:I was quoted $3.96/watt for a 7.2Kwh (24x300W) Suntech array install with a single inverter by a local contractor, seems a bit high, no? I'm a bit hesitant to commit to these Chinese panels. What would be a better alternative over Suntech?
