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.

There's no citation or research about the laws in question in this article, or the Miami New Times article it cites as a source, or the WFTV article that it sources.

From what I gathered in reading the three articles there's a state code that mandates that homes must be hooked up to the electrical grid. With out seeing the law or it's history (e.g. when it was mandated), it's difficult to say if it's malice on the part of utilities or just a poorly worded law from 50 years ago.

Electricity is regulated, like water, because it's something people have a hard time living without in modern society. It's perfectly reasonable for the state to mandate that properties have power as a protection for tenants.

It certainly sounds like the power company is doing nothing to accommodate those who would like power by having policies in place for reporting solar hookups to protect linemen or offering bi-directional meters to avoid billing irregularities, but there's no evidence presented to support the assertion that they lobbied to prevent solar.

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?

It's not necessary. If you produce more than you use consistently then a good sized battery bank may be all that you need. A lot of new home appliances are so energy efficient they are starting to see use on sailboats.

Solar cells can produce at load. It's not like panels that aren't connected are melting down, like nuclear.

I can see an opportunity here for the grid to become owned/operated by the people, not massive corporate greed machines. A house who has excess sells it to neighbors who do not have the solar capacity where neither are connected to the normal grid. Throw some technology into automatically shutting down the generator side every X hours unless its given authorization wirelessly. This foolproofs the root cause of uncont…

You still have the back feed issue. Sooner or later, someone is going to have to do maintenance on that new grid you just created.

Disconnect the grid on both ends of the issue, fix it, then reconnect?

ok, so its illegal to power your home with solar... but is it illegal to charge a battery with solar in Florida? Powerwalls would still be viable and legal right?

It's illegal to occupy a house that is not connected to the local power grid. The power wall would effectively be redundant and mostly useless. You have to get your power from the power company.

You can point fingers and say it was them lobbying, but everyone who didn't do something to act in the opposite direction could have influenced but didn't. I say this not to blame more but to motivate people to take responsibility and to act, to stop people from thinking they're powerless (no pun intended).

In other words, lobbying is great and there should be more of it! I think people here are disappointed not so much in this particular outcome, but the harmful effects of a political system that is nearly entirely fueled by lobby money. I mean, in other countries they call that "corruption".

One particular outrageous mob-lob in germany is the driving instructor caste.

Basically, the old generations, are allowed to drive everything with there old driving allowances.

Now for every generation coming after that, new driving allowances are needed, per various class of vehicle, wether you have a trailer attached and so and and so forth.

Its the new kind of mob activity, that uses the law to pressure people into paying for unneeded services and obstruct buisness for new buisnesses.

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.

The title of this article is quite misleading. It's not saying that it's illegal to have solar panels powering your home, only to have a solar system that does not tie into the grid. Then making it seem that requiring anti-islanding protection is some act of malice.

The controversy is over what happens when the power supplied via the grid goes out. There are generally two options that could be taken here, in light of the argument that a powered house connected to an unpowered grid is unsafe:

1. Any solar system on the house would be required to shut off at the same time, leaving the house without power from any source, or

2. A solar system on the house could continue to provide power to the house, but only if the house is temporarily disconnected from the grid while doing so.

Florida law effectively requires (1) and forbids (2). "Effectively" because, although a switch is present which could disconnect from the grid temporarily to allow the solar system to power the house, only the power company is permitted to operate it, and in fact the power company is permitted to physically lock the switch to prevent disconnection from occurring, thus preventing the solar power system from being used when the grid is down.

The net result of these policies is that, yes, it is in fact not legally possible to continue supplying power to your house from solar when the grid is down.

The spark for the article, so I understand, is that regulation advocated by FPL made it illegal for homeowners to access that switch. So, in the wake of the hurricane, it was explicitly forbidden for folks with solar systems to power their own homes.

You are describing a rational, reasonable regulatory system. :) Sadly, not the one in force.
