Thats about right. Lots of renewable resources to go after. Im in a really crappy area for solar however... Tons of trees that i cannot get rid of Because the property is only 1/5of an acre and trees practically surround it. My next home will have more land and a solid southern facing roof for sunlight.Do you know, that with watercooled PV panels happens the same
than it does with watercooled led light ?
PV panels can get very hot in summer (130°C).
Each Kelvin you can bring down the panel temperature, it produces ~0,5% more electricity.
more info i.e. here:
http://www.engineering.com/ElectronicsDesign/ElectronicsDesignArticles/ArticleID/6123/Photovoltaic-Thermal-System-Achieves-86-Efficiency.aspx
Hybrid liquid cooled panels i.e. can produce ~ 265 Wp + 888 W heat power / 1,59 m²
Only good to have, if you need really a lot of hot water in your swimming pool or water tank.

Not only that but combine with slate floors and walls where the light touches and the rock can save heat from during the day and release it at night. Lots of cool design features like that can really cut costs across the board.
I actually have an electric car and all power tools and lawn equipment is electric as well. As a matter of a fact my quads are electric, electric dirtbike, electric bicycle, working on converting a go kart to electric, and converting my boat to electric probably next year. Plan is to have a well insulated airtight house on a larger plot of land with a mix of solar and wind since this area of Michigan has a decent amount of wind (13mph on average). Then have a used nissan leaf or Chevy volt battery as the house power buffer and not use any outside electricity. I also looked at mini split air source heat pumps as they have drastically improved in the last few years. They now work down to -20°f and have insanely high efficiency. And their cost is only $1500 per unit. Ive calculated only a maximum of 3 of those for about 1500sq feet of space. With solar heating involved and some passive solar techniques, winter heating should be almost covered just by solar. That and then everything would be electric and powered by all renewable resources. The perfect net zero living. Being able to grow food all year round, and not have any utilities or fuel to worry about ever.
It really is quite sad. If everyone knew all the tech that is out there and the insanely fast returns on investment just by using them, we would be living in quite a different world right now. I know some people are super stubborn in their ways, that might be a big reason. I know a lot of growers of marijuana that still use HPS for lighting and treat it like that tech came from god himself and everything else is just plain evil. I find that tech to be completely outdated, unnecessarily complicated, and only efficient for the first month. And that is if you just completely ignore the cooling costs for those systems since you cant watercool them with a small pump. Heck, i mention aquaponics and they always think hydroponics and start complaining about how complicated hydroponics is with checking nutrient levels and so on. I dont even check nutrient levels anymore. The system when established seems to keep itself in check fairly well. Just grow at least one plant per medium sized fish. This is just examples directly related to growing plants, but the same can be applied to people using gas cars when electrics are now getting better, or buying a new furnace for $4k-6k when they could've bought heat pumps for the same price. I know someone that paid almost $15k to get electricity ran to their new house that sat really far back from the power lines and now that person pays for every bit of electricity consumed...anyone else have examples like that where you just shake your head and wonder why they didnt listen when you tried to suggest a better way?

Look into 'passive homes'. It's a design technique that takes advantage of super insulating the home so that it gains/loses very little heat. The calculations you mention assume a normally insulated house. With a passive home, one would be more than enough.
We're in the midst of an electric tech revolution. A lot of people simply don't understand the possibilities now available and becoming more affordable literally every day.
Sadly, many people don't understand the time value of money, so return on investment calculations mean nothing to them. This is called 'poverty thinking' for the condition it inevitably leads to.
I think im just cautious with 2-3 just so they run minimal power to each raising their efficiency and also as a just in case as Michigan winters can be unpredictable. Most well insulated and air tight designed homes can take less than 20,000btus to be heated with no outside heat sources like passive heating from sunlight on thermal storage mediums or active heating like solar heated water. Many different methods of heating can be designed to work together to make a really great net zero home. Only thing to do now is figure out how much energy it would take to make a year round greenhouse work. Im thinking it will take a ton of tanks and a combination of natural sunlight and water cooled led lighting to make hand-offs between each other based on how much light is coming in. A light sensor can be combined with a controller programmed for keeping a specific amount of light during the set hours of wanted growth times. And leds can be ramped up and down automatically as light levels change. Then of course my favorite go to for more heat is heat pumps for winter use and maybe even a mix of solar heating to go along with solar photovoltaic panels. Lots of variables to go through. But i think there has to be a combination of all these that will work.

Ken,
Have a look on my thread for some economical ideas related to what your up to, I cover my version of water cooling starting on this page.

Jesus mouse in a cannabis study, what a rabbit hole this link turned out to be! Lol
Great stuff!
Yea those bars are much larger for cooling block. It definitely would make for a much better setup using those. I mean the gpu cooling blocks arent expensive, but have limited space. I will do one that way though for the other large tank.
