Why mini inverter, and not a big one? Should be cheaper Wink

I like micro-inverters because they allow me to track individual panel performance. Also, if a panel is shaded for part of the day, it won't drag the rest of the string it is part of down.

But yes, cost is higher, but you avoid dealing with high voltage DC and the now mandatory rapid shutdown those requires, making the cost closer to equal.

After the "ground work" inspection, I was then able to back fill the trenches and seed:

See the two lp tanks I assume they are filled time to time.

Can you build a blast/fire wall?

cheap and easy..

2 fiberglass blanket

https://www.amazon.com/Tonyko%C2%AE-Fiberglass-Fire-Blanket-39-inch/dp/B01N1F737R/ref=sr_1_3?

the large 78 inch size wraps around these three pieces cost 50 for 2

https://www.homedepot.com/p/James-Hardie-HardieBacker-3-ft-x-5-ft-x-0-42-in-Cement-Backerboard-220023/100170507

backerboard shields blast-fire cost 2 for 27

https://www.ebay.com/itm/STAINLESS-STEEL-SHEET-035-x-36-x-48-304-2B/311385729636?
prevents backboard from shattering cost 50

so blanket - backerboard - stainless steel - backerboard - blanket

about 1 inch thick about 130 to build.

and it would direct blast-fire of tanks away from the building. Seems dumb I know but I have a cousin in firefighting and he has seen 2 or 3 of those tanks ignite . He said 1 home had almost no damage due to the blast/firewall I just described.

I am getting a replacement msi 1070 water block today. last card leaked

https://www.amazon.com/MSI-GeForce-1070-HAWK-GTX_1070_SEA_HAWK_EK_X/dp/B01HBG0VY0/ref=sr_1_5?

msi was under 15 days on replacement.

By the way solar is very nice it has been very good to buysolar and I.

Very nice. I'm in Western Australia so we get sun for most of the year. I max out my inverter during the day but of course get no use out if it at night.

Will get great when battery storage comes down in price in a few years.

If you are generating an excess amount of energy because of extra solar panels, with a net metering setup with your local electricity provider, you could use the excess electricity generated in the morning at night. Usually tho they buy your electricity at a reduced price from what they sell it at but if you have a large solar array then you should also be able to offset electricity expenses at night time.

Where I am unfortunately we only have 1 energy provider and they basically have a monopoly on the service.

We get paid 0.07 cents a KW for unused surplus energy that goes back in the grid but that's all.

"Perth may be one of the most isolated cities on the planet (it’s closer to Singapore than Sydney, and closer to Jakarta than Australia’s capital, Canberra), but it’s also one of the sunniest. In fact, it’s officially the sunniest capital city in the world, with an average of eight hours of sun per day, year-round. "

Unfortunately that means the energy provider likes to keep profits up and with the plunging price of solar electricity there is little incentive offered

have you thought about adding other forms of renewable energy? like wind turbines? there some really good ones these days, also what about power storage all the extra panels only do soo much good, you produce enough that energy storage should be something you might wanna look at, ive been looking to do solar and wind myself but am limited by the size of my property. Washington state has some great solar incentives like getting paid more if you get certain things that are made in the state like the solar panels and inverter

I definitely don't have enough space for turbines. I don't know if you know much about POWR ledger? It's a great blockchain project it would really benefit someone like me if introduced to my area as I could basically "sell" my surplus solar for credits that I could then maybe use at night when I am not generating anything.

haha lol not the ones your thinking of, not those HUGE ones that you see along the road, theres really good residential ones now that are small and nice looking, couple that I looked at did 3 phase AC, small enough for a property like yours you could have multiple which would give you some power generation at night

Ah that makes more sense

I wasn't aware of a smaller version personally I haven't seen them this way as pretty much everyone just sticks with solar but its a great idea as it would generate a good amount of power in winter while the solar is hardly getting used. I definitely need it to suit 3 phase power due to the draw I am getting from the pool, air conditioning etc.

Thanks for this amazing post. Great work Crazydane! It looks like a really fun and rewarding project.

I really would love to try something like this on a smaller scale for a personal project, and I have some ideas about doing something like this for a community project as well.

Rserved - Part 4 Energy production, impact on power bill, and tracking usage vs. production.

which site did you order the panels and micro inverters and everything else needed? I'm curious

For the 2 most recently installed ground mount arrays, I ordered the panels and mounting hardware from Renvu the last time they ran a special with free shipping.

The micro-inverters, solar panels, end run connectors, and associated cabling and such, I ordered from Streakwave.

Rough ball park on cost:

$200 280W Solar Panel
$100 250W Micro Inverter
$50 Solar Gateway
$20 End Run connectors
$20 Y-Cable

So to build a 24 panel array, you would need:

24 panels
24 inverters
24 Y-cables
1 Solar gateway
2 End Run connectors

So about $ 7,770 for a 6.72 kW array. To this you have to add the cost of ground or roof mounting, plus conduit, wiring and breakers, to tie into your existing system. Doing everything myself, I've been able to keep the cost down to about $1.25 - $1.50 per watt. Most solar companies offering turn-key solutions charge between $3 and $5 per watt.

Do you not have a net metering arrangement with your power company? I'm basically using the grid as my battery. Any excess energy I used during the day is pushed into the grid, and I'm credited the exact kWh I push in, and I then pull those back out at night, plus whatever additional kWh I need. If I push in more than I use over time, I build up a "bank" of kWh with the POCO. Before I started mining, I had build up a bank of well over 1,000 kWh.

Miners are up and running already. Please see my updates in the 4th post.

Nice work. Cool

With 16kw of miners your solar panel investment should pay off pretty quickly.

Looking forward to more updates. Wink

Good project Dane! I have done similar with 21.6kW panels / 5kW miners. Very fun and satisfying synergy.

Yeah this has always interested me. I sometimes 'feel bad' about pulling electricity for mining, which is mainly coming from non-renewable sources (although where I live the council/government is trying to increase its amount of renewable energy).

Having a clean mining operation is great, because you get all the benefits of mining, without the added electricity consumption pumping out fossil fuels and adding to your quarterly running bill.

That's awesome - I've seen a lot of people on reddit talk about the feasibility of doing a solar mining operation. Looks like a great project - I'll follow.

I think you could do a blog on a place like steemit and probably get a few people interested. It's a bit hit and miss over there sometimes in terms of what gets popular but you could make a few bucks if the right people read about your project, plus you've already done the work by posting about it here.

Do you already have the miners all set up, or will you get them (or more) once the solar system is all up and running?
