I love to see solar mining projects, this one looks more legit than most! When you say 9.5kW that means it can supply up to 9500w of power? I'm not sure but I believe with solar it's different, if it were 9.5kW you wouldn't get 9.5kW/hr. If so though, that's legit if it's all coming from solar.

9.5kw means in a perfect scenario it will generate 9500w per hour.
But at best it reaches 92-98% for 1-2 hours a day. Pretty much a bell curve from sunrise to sunset on sunny days.

US power runs on AC voltage, panels usually produce DC. You always lose ~15% in conversion. If you are off the grid and have a battery. You lose anything you generate in excess of the battery capacity (which degrades like your cell phone). Also, if you store on battery, you lose a further 15% storing and retrieving. For that reason I chose grid tied and get 1:1 production/usage of my excess power. I have net metering, so I use the local provider's grid as a free battery that defies the law of physics (no 15% loss), and costs nothing to maintain

Interesting, thank you! I love solar but 1-2 hours of uptime per day doesn't seem great. I guess it's free electricity though so you can't complain too much.

Uptime is direct sunlight hitting it. midday when sun is overhead is when you can get close to theoretical max. during winter with my 10.5KW system, I was getting 45-50kw on sunny days, now around 65-70kw, I expect upto 90KW on a sunny day in mid-summer. This is because closer to the summer solstice the sun is at the highest point in the sky and the days are longest. Closer to the winter solstice, the sun is at the lowest point in the sky and the days are the shortest.

Again 'bell curve', look at prior posts, there are charts reflecting the pattern of generation.

Antminer S9 eats 30-40KWH per day depending on hashrate and powersupply/voltage used. I couldn't run two S9s in the summer because 90KW a day is optimistic sunny day. Avg the days of the month and you will have partly cloudy, ominous, rainy days. Winter avg day was probably 22 KWH, Spring 35KWH a day, Summer maybe 45-50KWH

I do not recommend Solar for Mining, there is nothing free about the electricity after massive equipment investment.
I do recommend Solar for people who use to power their homes long term (15-25 years) especially when their power is >=0.15 cent per KWH.

There are so many positive reasons to go solar...  I'd recommend it to anyone who will be living in their home for 8+ years that lives somewhere with a lot of sun and doesn't need financing.  When you look at all the incentives, added resale value, tax breaks, and rebates, it's overwhelming how much positive there is in going solar.

For the average installation, the authors found that solar panels added a $20,194 premium to the sales price of the house based on repeat sales data.

Ognasty,
your system is nearly identical to mine and also in northeast. Your production should be almost a mirror of this:

I have 35 Sun Power panels  10 facing south and 25 east and west.

My install was also a tad more since I paid to move 2 vents so the panels were contiguous.
The SunPower panels also handle albatross poop better than Hyundai panels.

Were the birds actually nesting under there?

I had to pay a little extra to have them vertically installed instead of horizontally (don't ask) to avoid having to relocate any vents. 

There weren't any birds nesting, but it's a precaution they take out here to keep it from happening.

So those periscope-looking things are vents coming out of the roof??  I kept wondering wtf they were  Cheesy

Yes, I believe the 2 you're looking at in the picture are for a bathroom vent and my clothes dryer.

That's kickass! I live in Florida, lots of sunshine here, will be placing a nice size grid on our next house when we buy, although I'm looking at it from a larger piece of property and an array on the ground. Kudos!

What is the return of energy to installation cost ratio for both the solar panels and the turbine?

Would be interesting to know which has provided better ROI.

The turbine hasn't been installed yet, so it would be impossible for me to say definitively.  That being said, the solar was installed on a much larger scale and where I am located it has obvious advantages.  It will be interesting to see the data, but I'm guessing the solar array will be much more efficient cost wise.  I also suspect the moving parts on a turbine make it far more likely to need repairs and shorten it's lifespan compared to the solar panels.

Keep us updated when it is fully operational!
Do you have the Energy production per meter squared on the solar PV cells, and what type of PV did you go for?

It is a good project for environment for sure. But is it cost effective?

Not only is it cost effective and socially conscious, it is the fastest and easiest all but guaranteed investment I've ever made with or without the Bitcoin mining aspect.

Relocating the existing thermal panels to make room for the photovoltaic panels caused them to no longer drain properly.  This was resolved by adding a secondary drainage pipe linked to both panels and connected to the main drainage pipe.  While there is still some cleanup and painting to do, I am happy to report that it is fully functional so there is no longer a constant bubbling sound as the panels struggle to drain water back into the system.  I took the opportunity to fly my drone and make a video showing a section of the upgrade.  Enjoy.

Using solar energy to mine bitcoin Huh
Or as a kind of other investment Huh
I don't understand
