What does it cost to have a solar setup?

Fri Jul 19, 2013 8:29 am

I honestly have no clue how to power my car using solar power. However, I would really like to - especilly since I would be able to charge the car if there was a power outage or something.

How much does a solar system typically cost? I am not talking the works here, just what I need to replicate a 240v (Lvl2).

I think it is the perfect way to charge a zero emissions vehicle! I just have no concept of what a potential cost could be, I guess Im just looking for a ballpark, a range...nothing specific.

What would be a very high price?

What would be the lowest possible price? (for example, you might say - "you would not be able to get the solar system installed for less than $XXXX")

The short answer is, "it depends". You'd need to tell us how much energy you use (number of miles driven in a typical day).

Lets day 40 miles a day. I loose about 4 "range bars" during my commute on week days.

Or - lets say to go from 30% -> 90%

I hope that helps

Depending on the size of the array, you might want to consider a prepaid PPA (power purchase agreement). There are many vendors, and I would start with the local ones. If you needed a competitive quote, SolarCity, Sungevity and Real Goods Solar could be good places to start with.Image

Ballpark? No specifics? You need a 3.5kW array or so, maybe 14 panels and inverter(s), plus wiring etc etc, roof mounted is cheapest, DY $5k, contracted out say $10k minimum.

Inverters shut down in an outage. I wonder if it can be configured for 3 phase 440 DC just for QC.

Typical grid tie system will shut down if the grid goes down. You will not be charging the vehicle during a power outage unless you opt for a battery back up type system at substantial extra cost. I paid Solar City $17,000 for a basic 3kW (DC) grid-tie system.

Hopefully a long time ago??

The cost per watt installed should be well under $4 these days.

To be able to charge during the day is going to require a battery backup system which is going to add significant cost.

I think a better question to ask is what is your budget for a solar system and how long are you able to wait until you've recouped your cost. Then we can tell you if your expectations are feasible.

If you are serious I would considering giving a local PV installer a call and getting a quote. Their quote will include all of the available incentives and what kind of ROI you can expect.

We were able to get a PPA at 6 cents per kWh from SolarCity. It's prepaid, which means that we won't break even until after a few years. That said, and seeing how solar prices are plummeting, it's conceivable that PPAs will be competitive with local utility rates in the not-too-distant future. Pay-as-go PPAs would offer an immediate economic benefit and will hopefully facilitate wider and more rapid adoption of solar. That would sure be a nice thing to see!

I'd like to get into this too but not sure where to turn. I'm thinking the guy standing at the Costco kiosk may not be the best place to start :lol:

$5k or a little higher sounds about where I'd want to be. $30k is no bueno, too much to lose if I move or a hurricane blows it away. Is that a post credit number? So I could get about 30kWh a day from a system like that? Let's see, that's three bucks a day, roughly cut my FPL bill in half, 4-5 year payback.

Down here, you'd need something like a 7.2 kW system (thirty, 240 watt panels) to average 30 kWh a day.

My 7.2 kW system cost $38,000 to install with microinverters. A central inverter would, probably, cost less, but I have partial shade issues to deal with. I, also, paid a bit more to get three anchor rails for each panel to the roof, rather than the typical, two rails per panel. It ain't going nowhere.

After the FPL rebate and the Federal tax credit, it only cost me a little over $12,000 when all was said and done.
