Can I use many of these on my tin roof to supply power to my house? How many would I need to generate 2,400 KW a month?

UHM Are you sure you need that much power in 1 month? I use 300kWh at most at my house. Assuming you mean average over a year and not 2,400kWh worse case, you would need around a 25kW array. This also assumes the system is facing south and not obstructed by trees. This is a large system and you would need 174 panels. Typically a residence has around a 5kW array so yours would be 5 times larger.

Yes you can use multiple panels but keep in mind 2,400 KW = 2.4 million Watts. These are amorphous panels and are only about half as efficient as crystalline panels. In other words, you can at least double your efficiency with crystalline panels. You would need 70 of these 144 watt panels and 8 hours of unobstructed sunlight per day to generate 2,400 KW per month (70 x 144 x 8 x 30 = 2,419,200) not including losses. And that's 24 volts, not 120 volts. So you can see, it is not an easy task.

I just started testing using a "kill a watt" meter($20) in cleveland. Skies that look like an ad for prozac. 65 watt max so far with 1killowatt hour accumulated over 1 week. My garage roof angle isn't the best(west). More data soon, follow up. Kw is a load measurement, kwhour is accumulated consumption.

this power converter can handle up to 500w electrical appliances. you should buy 1000W power converter (or more)

Can't be per month, as it's rated at 10 KW output, which if it ran 24/7 (i.e. in the dark too) for a month, would only produce 10KW * 24 hours * 30 days = 7,200 KWH. A number nearer to reality would be 10 KW * 8 hours/day * 365 = 29,200 KWH, which assume it's always perfectly sunny and output is at peak level. So under realistic conditions in a very sunny location (Arizona say), I might believe 20,000 KWH per year.

Technically you could, but you'd need a lot of 'em. Grid-tie systems tend to have more power. If there's one near you, I'd suggest contacting a local solar power shop to talk about grid-tie; those systems are much more complex and regulations vary from location to location.

I just read an article in Home Power Magazine that may help you get started the right way.Look up Home Power 157, October & November issue. The article is called "An Educated Move Off-Grid". A lot of people might respond to your question with questions, the big one would be What do you want to do with Solar Power? What are your needs? What is your amp load? All these are answered in this article, so you should do your best to get it asap, read it, and go from there.

I've never done a calculation on it, but these lights can't use more that a few watts per hour due to being LED.If I had to venture a guess, MAYBE $1 a month to run 2 every night. That's probably overestimating.

This IS an off-grid system. I have never been on-grid at my present location. I run 24/7 with 4 of these kits (8 panels), feeding a set of 4 panels through the included 30-amp charger to recharge 3 large deep-cycle batteries each set (6 batteries altogether). The batteries feed an 800-watt Cobra inverter (also from Amazon) to provide all the power I need. For high-drawing electrical shop tools, I use a 3500-watt LPG generator. See my video series at my website, DroidPals dot com.

468 Volt-amps with a .85 PF ought to consume about 400W/hr. Power companies usually charge more in the summer months than winter, as high as 14c/KWH (including taxes). So, youre looking at 5.6 cents/hr. It would be interesting to know how many degrees cooler it maintains your attic. If a 10% drop in the difference between attic and interior temperatures, then expect a 10% drop in heat gain (BTU's per hour)

Yes, you should be able to run a couple of laptops and some lighting. Double check by looking at the generator's wattage output and the watts used by your devices.

It is self powered so I do not see why you could not, although I am not sure how many you could do total.

I use mine to power my one person wood working shop. If you are doing an 8 room house you have to decide if you are going to be on or off the grid? Then it is going to depend on how much power you need at the peak of the day and the total amount of energy used in a normal day. Grape is a great brand somewhere between 30 and 45 160-200 watt panels will do it.

2 would be fine. Lots of power here. Back wall pointed out. I have 8 of these and they are THE Best you'll find anywhere. All are over 5 years old. I use them everyday. Not a problem....ever.

I had an old 1700 watt generator during sandy. It powered my fridge and a bunch of other small things. The 3000 watt inverter isn't overkill tho. It won't draw more power than it needs. Battery needs to be good and charged as much as needed. Car alternator at least. Cables need to be thick for 3000 watts.

I have a two story house but this is not what determines whether or not this will power it.It is based upon amp- watt etc. In my house I have a 200 amp service- once connected to my house (use a qualified electrician---always) I was able to run the boiler, AC, Stove and fridge with misc lights on in the house. The point is to manage while you have no power and toggle if needed certain rooms. This works perfectly--even though it runs high, continuously- does the job!

Yes, but beware, you probably want to charge more than just 1 battery, more like a small bank of batteries. For example, I have mine hooked up to a small bank of 8 SLA 12V batteries giving me about 1500 watts stored to power a 1200 W Inverter for appliances. It's like a solar powered battery pack so that I can work and have phone conversations in the most odd places (no generator noise in the background, just pure silence or nature noises, it's awesome). You'll want a decent charge controller (I bought a 10 Amp controller, which is overkill, but has the better charge-methods and pattern that I wanted). Good Luck!

This doesn't produce enough current for that. Just not enough power. You'll need something larger.

You can use as many as you can feed. Base power is around 360-280w each. Overclocked to 190GH/S expect 415w each.
