Isn't it necessary to have the grid as a backup consumer? What happens if you over produce solar energy, but don't have the necessary means to dissipate it?

Solar panels get less efficient as voltage increases, hitting zero at a reasonable point. This is very convenient, since all you need is a buck converter in the battery charger and any unused power can be ignored.

The power still exists, of course. It just ends up heating the panels, which are fine with that.

Do they have the authority to enter your home and check what kind of power you are using? What does it stem from? Can you shoot them for trespass? The same thing WRT rain water which is mentioned in comments. To me it seems like an unreasonable invasion of household borders: trying to regulate something confined in a household.

This seems to be straight from a dystopian movie or book I'm not sure it isn't a joke. Is the "get off my lawn" a thing of the past in US? What business have US gov, or anybody else for that matter, to do with what I do on my property?

The main reference is a page giving guidelines for what sort of equipment is required for connecting a solar system to the grid for net metering.

Of course there will be some requirements for that, and most systems that use the grid for "storage" aren't setup to power the house when the grid is down. Thus the system that isn't capable of powering the house without the grid is off when the grid is off.

The question of whether one can operate a house with solar+battery when the grid is down is not really answered by the article.

The article is trying so hard it's hard to tell what the actual issue is. It is dangerous to backfeed the grid -- you may kill the line worker coming to fix a blown transformer or downed line. In some places a grid connection is considered necessary by the building code. If so, you must use proper equipment.

Well a lot I'd say, given that your home has to conform to tons of local building codes.

I think his point was that it's not a legitimate role of government to interfere in the details of your private life inside your own home, especially when they affect no one else.

It is however legitimate to ensure that you're not going to electrocute nearby power workers who aren't even on your property.

So don't backfeed the grid when the grid is "off" That has nothing to do with powering you own home from you own solar panels. When the grid-tie inverter senses the grid is down (it could even be scheduled outage for maintenance) - it stops feeding the grid and only powers the house. When it senses the grid is back it ties to the grid again. If you need to work on the house, there can be a master switch where the pan…

You can't run loads from cells directly, you need a battery and inverters. Or every cloud will fluctuate the voltage and watts massively and your electronics will fry. In the olden days, flickering incandescent would be fine.

As the other reply says, it's quite possible to power electronics from the cells (but not directly). What you need to look for are the types of regulators and batteries used in caravans. Of course you cannot connect such a system directly to the grid.

Yes, it's required for generators too. You have to install some sort of switch (I forgot what it's called) so the house power doesn't feed back into the grid and kill a lineman. The title is very misleading as well. Just goes to show that Fox News and their ilk aren't the only ones who do fake news, it's journalism in general. Also, the title is an outright lie: "Thanks to Lobbying, It's Illegal to Power Your Home wi…

No you can't shoot them for trespass.

Florida has strong "castle doctrine" and "stand your ground" laws. If you can convince a jury you were afraid, you can do pretty much anything you want on your own property.
