Solar Panels + Bitcoin Mining

[bestBTCdomains]

Can we get a new thread going?

Anyone have any experience? Is it worth it?

Hi there I'm pretty sure this thread already has a bunch of the info you're looking. As well as off shoots to other threads with more info.

Good luck

Quick way to produce solar power is to use a grid-tie micro-inverter like this
https://bit.ly/2hkAAfc

Solar Panel -> Micro-Inverter -> AC socket

No batteries needed, no maintenance, no extra fee.

I use same one with 2x 260W panel.
I don't produce much but it's fun project.

Guys, i thought about it. And at this point its not worth it because most PV panels are 1)NOT cheap 2)Has very low coefficient of efficiency(15-20% at most) with straight sun beams....
The technology is improving and when we gonna have mass PV panels at low price and at least with coefficient of efficiency of 40% and above, then it will become worth it. And it will not only support your whole crypto farm, but your household as well

Forget solars. Just go with the wind turbines.

You can add solar for extra juice but I just wouldn't fully depend on solar panels alone..

[AlphaInterceptor]

Lol, yeah forget solars buddy

P.S. Sun is everywhere, wind is not(at least not at the quantity to move the turbines).

A combination of the two should be pretty reliable. Solar is best during the day (for obvious reason) but wind power tends to pick up at night. For small use a vertical-axis turbine tends to be better than horizontal-axis, requires less wind just to get started and typically doesn't have to be as tall to capitalize on local air currents.

@Sidehack, do you have a recommendation on vertical axis turbine?  I am in NW Indiana where we have 5-6 m/s average wind speed.  I'm currently using about 15kW for mining and was starting to look at options for offsetting power bills.

[sidehack]

Honestly, everything I know came from talking with Novak the aerospace engineer. One of our future plans was to shift everything to renewables so we'd probably end up building some VAWTs and he was looking into it.

I have conceptual knowledge but no real-world recommendations of existing products.

I've got a thread about my solar/wind mining operation.  Tesla Powerwall 2 battery to be installed soon:

Wouldn't it make more sense to simply sell the energy back to the electricity company (in areas where it's possible)?

I wonder what the profit difference is?

Mining is much more profitable than selling energy, in every situation I'm aware of.

mmm this is an utopia, did you know that right?

Do you know the installation price and maintenance for that kind of wind turbine?
Not to mention that is clearly a photoshop, you can't have one of those beside you house, the risk is too high you can end with a blade of those crashing the entire house.

[mindrust]

This is not an utopia. This is totally doable.

Tbh, I am not aware of the maintenance costs but i can assume that it is not cheap. Still, if it wasn't profitable to run wind turbines, nobody would be using them now right?

The photo is just to give an idea. I agree, you'll probably need a very big yard to run a wind turbine that big.

The thing is; You don't need to own a wind turbine that big, there are many variances of it. (small, big, medium, sideways, vertical etc.) Even some sailboat owners use wind turbines to generate extra electric.

It is not rocket science and it is profitable.

Maintaining solar panels is also not that easy. I watched lots of videos and overheating solarpanels  can also cause efficiency losses. People who own solar panels are constantly water spraying their panels to keep them cool.

[OgNasty]

Space for the blades isn't a huge issue with wind turbines.  They are typically located very high above everything else by design.  Noise or visual complaints from neighbors is usually the deterrent.  That being said, if you don't live in a windy area, you will not produce much power.  So far maintenance hasn't been a big issue for me, but installation costs were more than the turbine itself.  My area is not an extremely windy area outside of monsoon season, and I've calculated the payback period at 20+ years, whereas my solar panels will pay for themselves in 6-8 years.  It is my opinion that wind turbines are great for the use of charging a battery, like on a boat, or remote shed.  Using it to feed power directly into the grid is less beneficial than you might think unless you live somewhere with extremely high winds and you are able to install it 30+ feet in the air.

[miguelmorales85]

That is interesting, I did not know about solar panels being water spread-ed because of the heating.
So I was not aware that efficiency was affected by heat, that could be a manufacturer issue because of course the panel that will (or would) receive all the sun could get hot (duh)

Also, solar panel technology (efficiency) has advanced more than turbine power technology.

[OgNasty]

I have never once sprayed water on my solar panels due to heat or seen anyone do this.  About 30% of the homes in my area are solar powered.

[sidehack]

Because local power generation is a long-term investment and bitcoin mining farms are operated by short-term-profits people. They're set up in places where low electric rates already exist.
