Acquiring solar panels at home can be an expensive hassle for people in the US. But small, simple, plug-in solar panels for use on balconies are soon to become available for millions of Americans, with advocates hoping the technology will quickly go mainstream.
Earlier this year, Utah became the first state in the country to pass legislation allowing people to purchase and install small, portable solar panels that plug into a standard wall socket.
When attached outside to the balcony or patio of a dwelling, such panels can provide enough power for residents to run free of charge, home appliances such as fridges, dishwashers, washing machines and wi-fi without spending money on electricity from the grid.
Balcony solar panels are now widespread in countries such as Germany where more than 1m homes have them but have until now been stymied in the US by state regulations. This is set to change, with lawmakers in New York and Pennsylvania filing bills to join Utah in adopting permission for the panels, with Vermont, Maryland and New Hampshire set to follow suit soon.

(2,689 posts)Unless I am incorrect on this, if you plug your inverter into a wall socket, that energizes the line. The problem is that if the power goes out at the location, and if the inverted is plugged into the wall socket, the power line is energized from the panel and could potentially harm/kill a lineman working on the problem.
It follows that the other countries have taken this into consideration. I wonder how they protect a lineman who is working on a power outage.
Anybody know the answer?

Very dangerous for linemen.

(2,689 posts)So it appears that you concur with the concern of energizing a line during a power outage.
I wonder how the other countries do it?
Also, 1KW is not a lot of wattage. My fridge uses 1kw per day. But it could power lights and a washer 1 maybe 2 times.
And, since there is no batter storage, it would only work during sunny days.

(7,909 posts)as far as plugging it into a power outlet, I would think you would have to keep it away from the same system that is using the power company as a source. What type of current is being generated by solar? AC or DC? I have no experience with it.
SnoopDog
(2,689 posts)That implies that an inverter is required to convert DC to AC. You cannot connect DC to an AC outlet.
And what happens if 100 of these 1kw solar power setups are connected and the power goes out? And a lineman is working on the outage - 100kw is a death sentence.
I still am learning about all this. I have a solar generator with 4kw battery storage. In California, there are strict laws about solar because they can kill people.
I do wonder if the electric companies bribe enough politicians to mask the real potential of solar. Of course Republicans and nuke people would never do anything to help solar energy.

(13,506 posts)A kilowatt is a unit of power, a kilowatt-hour is a unit of energy. If an appliance uses 1 kilowatt (120 Volts at 8.3 Amps) for 1 hour it has consumed 1 kilowatt-hour of energy.
A modern, efficient refrigerator might use between 1 and 2 kilowatt-hours of energy per day, implying that it draws an average of between 0.042 and 0.084 kilowatt-hours each hour, which means that it's drawing an average of between 42 and 84 watts which at 120 Volts is only 0.35 to 0.7 Amps..... (not very much).
AND, from what I've read about these units they come with a small inverter which has a built in transfer switch function..... it will only supply power while it detects voltage on the outlet it's plugged in to. The user doesn't need to do anything to disconnect it if the grid goes down.

(2,689 posts)Thanks for pointing out my typos and laziness.
My fridge takes precisely 1.03 kwh per day (I have a kill-o-watt meter). It doesn't run all day but in a 24-hour period it uses 1.03 kwh/day. Isn't it interesting that the fridge runs 1.03kwn/day no matter what? Sort of means my fridge just runs perodically without any concern for coldness loss...
And groundloop, thanks for:

That would indeed work and protect linemen.
Do you have a link for that? I would definitely like to read it.

(736 posts)But a solar panel array from a balcony ain't gonna power a washing machine yo.
A fair portion of a rooftop would be required to do that. On a sunny day.

(30,983 posts)All the panels when they become obsolete junk? Art? Or just create more toxic dumps? How many can be recycled?
IDK...
Obviously, I have questions.
SnoopDog
(2,689 posts)Panels can last a decade or more. Recycling must be an option to everything we build...
