Anyone have any reviews about the off-grid 3000W solar kit from Rocksolar?

[markbron123]

I am planning to purchase an off-grid solar system for my cabin, and I have researched Rocksolar, an online shop, after carefully comparing the prices at other stores.Finally decided to purchase from them. Does anyone out there purchase any solar kits from them?

I'm allowing this thread since the OP is only asking for reviews.

There is a never ending barrage of here-today-gone-tomorrow inverter companies. And batteries for that matter.

I am not seeing any systems with rapid shutdown, but I imagine they are all ground mount not roof mount.

Other than it sounds 'classier,' why do smaller solar systems call their battery packs 'Solar Generators?'

Well, batteries run down, you know, but "solar generators" run forever on sunshine.

200W solar panels seems very 2007.

Whats a standard size panel these days 400W?

More or less, yes.

Q.CELLS makes a 605W module.

Ah yes, commercial will be bigger. To be clear, I was thinking of thr residential market when I agreed 400W is average.

I am not up on the panel technology but looking at the specs for the 200W panel
Seems lots of online sellers sell the same panel.
It also appears to be about 1480 X 670 mm or .99 square meters
and the q cells appears to be 2462 X 1144 or 2.82 square meters
200 / .99 = 202 W/m2
600/ 2.82 = 212 W/m2
So if I did the math right and data sheets are correct they are similar output per area.
price wise though a commercial panels look to be about $475 per panel or 80 cents a watt.
The 200W panels are sold for $239 individually or $1.20 per watt
I did not pick apart the price of the bundled kit so the may cost less as part of whatever kit the OP bought.

Smaller panels means more mounting parts and more points of failure in connectors. For residential rapid-shutdown compliant systems it also means more micro-inverters or optimizers or whatever. Perhaps handling smaller panels is an advantage for a DIYer.

A 10 year warranty with no 25 year performance guarantee is below industry standard.

I guess since its a 24 volt system rapid shutdown is not required as its always below 30 volts.

Wait, really? I'm seeing 48V battery in the ones I looked at.
Also parallelling lots of modules at 24V would suck.

Actually I don't know how it goes together I think this is the system the OP bought

6 12V 200W panels
2 X 24 V batteries
1 X 24V inverter, definitely early 2000's looking inverter
1 X MPPT Solar Charge Controller
All for 3,999.99
