  • As I said, 99 percent are grid tied no battery. You are the one percent and I think that is an important omission on your part. Your battery pack would cost around 40,000 U$ I estimate alone. Now if you are not grid tied, your solar installation will be very inefficient and often not matching your usage/charging requirements. Thus you won’t be getting the most out of the 6kwh solar panels. Often getting very little return. If it is grid tied which provides access to store excess energy, that is the most efficient system. But if you include that battery pack and try to match best efficiency, then you need a much more complex charger/controller. Add 50 percent to that cost. I suspect your installation on nearing 100k if it is installed in such a way to take maximum advantage of the sun.

    Now with the battery pack, you can utilize it to provide power at night allowing for maximum savings. But if you do this, there is no guarantee you will have any battery left for those frequent power outages you have. Thus to be reliable on battery, you must keep it at full charge at all times thus not getting any real financial returns on it. It is simply a 40,000 dollar ‘generator’ which doesn’t really make any sense both from an economical or environmental sense. The good thing is that it should last a long time if it is not discharged often. But if you operate it in daily usage, you will need to replace likely every 10 to 15 years. That is pretty expensive as well.

    While simple solar panel with grid tie can be both economical and environmentally friendly, battery packs make near zero sense from a return on investment or from an environmental sense. It sounds like you are using it to protect from power failures but that means it must be at 100 percent at all times ready for power failures. And if you are doing that, just install a far cheaper generator. Not only is it far cheaper, you can have days of power failure and the environmental impact is far less then the manufacturing environmental costs of batteries.


  • I installed 5kwh grid feed on my house and professionally have installed enough systems for communications towers to know the requirements. So ya I take it with a grain of salt when people suggest they can get any significant time from a battery backup system.

    Also 99 percent of the home systems are grid tie and do not have a ‘whole house’ battery backup. Thus I am suspicious to begin when they say they get these long battery backup times and hands their AC tired in. And to make me more suspicious, nearly all grid tie systems shut completely down if the grid fails even if your in full sunlight. This is for safety reasons. A few people might have power wall type of systems but for ten thousand your only getting a few hours out of that and only on specific circuits in your house. Something that requires a bit of complexity in your electrical panel wiring.

    And before you all find the 1 percent of systems that are fully backed up with battery, and they do exist, these systems to be viable have to be so overbuilt that they can cost hundred thousand dollars.




  • Not sure how to edit a post but will add this. I agree with you. We absolutely should be adding the cost of externalities. The only way to do this effectively is to add that cost at the consumption level. We should pay twice the cost for conventional fuel at the pumps. Heating your home should be far more expensive. Something that would also encourage people to take on roommates and fix housing issues. Taxing only or corporations simply means Russia or Saudia Arabia will increase their output while they laugh at us.






  • The US prosecuted any American citizens involved in this. The US supports many small nations and without that support, many fledgling nations would fully collapse and be far worse off.

    I don’t live in a world where perfection is possible. In a war torn country, there will always be individuals who will do evil shit. Even on the more good side. Do you think not a single Ukraine soldier has not done something immoral or illegal? Yet we support them.

    I wish there were no conflicts in the world but we need to grow up and realize there will be serious misconduct. And that is the cost of trying to encourage stability. The thing I take away from this is that the US did prosecute any of their citizens that were involved in this. As they should.
