How much did you pay for solar?

[quote=svelte]Got 71.1 kwh yesterday with 10.4 kw system.

Let’s see how they compare

6.83 = 71.1/10.4 – svelte
6.66 = 35/5.25 – ocrenter
7.01 = 31.54/4.5 – montana
6.5 = 24.7/3.8 – AN

Montana, looks like you’ve done best so far!

Also interesting that our results are so close together…looks like one can expect between 6.5 and 7 hours of energy on the BEST day of the year…

That’s probably on a crystal clear long day with zero clouds. Worst day will be much harder to compare apples to apples, since clouds will vary over the different homes.[/quote]

On Friday, June 19th, we generated 87.31 kWh with an 11 kW system. On Saturday, June 20th, we generated 84.3 kWh. We’re about 6-7 miles from the coast and the panels are new (within the last year). I’m surprised our generation is so good because we have trees that shade the panels during part of the day, and we also get the coastal influence. Must be the orientation or the panel/inverter types(?).

I just checked. I got 71.98 on Friday

6.92 = 71.9 / 10.4
7.93 = 87.31 / 11

Yours is way higher than the numbers others have posted.

Not sure the reason…a few possibilities:
(a) do your panels point due south? Supposedly the best orientation
(b) I have noticed inconsistencies in the energy reported, on the order of 3 to 4 kwh per day. For example, checking two sites for my house on Friday:
– My installation company’s website (sunrun) reports I generated 69 kwh
– My equipment company’s website (solaredge) reports I generated 71.98

That’s a difference of about 3 kwh.

How are you determining how much you generated?

Definitely an amazing outlier. Going back to Team San Diego on PVoutput, the spread is between 5 to 7 with the median around 6.4. Perhaps it is the type of solar panels?

I think it has more to do with roof orientation than branding. The pitch of the roof affects it to. Also, whether you have micro inverters or not and if you have any panels being covered by shades.

She might have SunPower solar panels, with efficiency at 21% and is considered the Rolls Royce of panels. The rest of us probably went with typical 15% efficiency panels.

She isn’t just beating the few of us on piggington. She’s got the entire team SD on PVOutput beat, and that’s about 60 various systems throughout the county. And the margin of victory isn’t even close.

She might have the most efficient system of the entire country.

So, when a panel is 15% efficient, it would be sold at 240W panel, but the same panel from SunPower that’s 21% efficient would be sold as a 336W panel. So, the amount of stated output would have already been factored in. I don’t see why SunPower would leave any on the table by “underrating” their panels.

I’m looking at the installer’s (Sullivan Solar Power) site. If there’s another way to find the info, please let me know because the numbers do indeed seem way too high (not that I’m complaining, if they’re right).

We have both west and south facing panels, with the majority facing west. And they do get shade at different times in the afternoon, and we do get some coastal fog since we’re about 6-7 miles from the coast (maybe a bit closer). They are Kyocera panels. We have string inverters — which I was lamenting until just reading this thread, if our numbers are correct.

For the record, 6/19/15 was our best production day so far.

These panels:

I might call Sullivan on Monday to make sure these numbers are correct. Agree that this would be pretty strange. If they are right…WE’RE #1!!! 🙂

So our distance is about the same. I have a chimney that does shadow one of the panel part of the day. But I have micro-inverters, so it should be more efficient than string inverters.

OCR might have figured out the reason for the discrepancy.

Good question! It’s 12,800 W DC, and 11,031 W AC. I used AC because when we were sold the system, it was sold as an 11 kW system. It’s also how it’s listed on Sullivan’s site. Would this explain the difference? Not sure how everyone else quoted theirs.

You’re probably right, OCR. If I calculate it based on the DC wattage, it’s more in line with everyone else’s numbers.

Sorry for the confusion, all.

Darn! I was hoping we’d be #1. 🙂

Wow, that’s a huge system! 40 panels?! Did you cover your entire roof? 🙂

I’m surprised Sullivan would advertise and sell in AC, given the rest of the industry all sell in DC and therefore it would appear they would have a pricing disadvantage.

[meadandale]

They provide you both numbers, DC and AC-CEC.

Great catch, ocrenter. I suspect everyone was giving their size in DC – I know I was. the revised number for CAR is:

6.8 = 87.31 / 12.8

which brings it right in line with everyone else.

It does sound as if she has 40 panels if she has the 320w Kyoceras.

We have 40 panels also but use the 260w RECs. We’ve got room for 10+ more panels, but it is looking like that won’t be necessary. We’ve been pleased with our performance so far!
