Solar panels. Useless or the future?

My dentist referred me to my docs (plural) who referred me to an ENT specialist who had me wired up overnight in a sleep lab.


Everybody said I needed a CPAP machine but the sleep lab record was marginal. I elected not to use the CPAP machine.

That was about 5 years ago. Since then I have seen the CPAP machine lose & regain its trendy status.

Certainly trust your doctor but remember medicines has its trends and obsessions too.

My docs still say my breathing etc is marginal. Big deal.

I can walk 2 miles easily, I sleep reasonably well for an old fart & I'm in my eighties.

Reminds me of the statins I was taking for 25 years.

I showed the doc research paper that showed that are now suggesting statins do almost nothing. Went off statins and my HDL/LDL remain fine.

I will continue my own path, thank you.

.



So everyone said you needed one except the people who did the test, which was marginal.

Record cheap electricity is transforming world energy markets as Canada struggles to keep up: Don Pittis - Business - CBC News

Article describing how alternative power sources have totally changed the electrical generation market.

Note the tense - have totally changed, not may change or could change

oil/gas/coal are already facing obsolescence in power generation.

interesting article on how solar is going to replace nat gas by 2020 in the US.

far sooner than previously thought

site C dam should be up an running just in time for the death of natural gas as a power generating option.

Not a clue what you are reading. That is just barely the output of one small generating station. Say how well do your solar panels work at night?

Statins are worse than junk, the good goes with the bad.

I think you missed the part about solar panels and batteries working together.

but don't worry about it, it will be 5-6 years before they take over.

To answer the OPS question instead of debating the politics of green energy.

You said you tested your panel not facing the Sun and got 0.2 Amps.
Solar Panels will not even get close to the rated output if its not in direct Sun. Even a cloud passing by will crush the Amps. And you can not estimate the total power you are going to get by how many hours of daylight.
The suns power changes all day being strongest at noon and very week near sunrise and sunset.

IF you have to use that panel I would always keep it facing the Sun and at best maybe say 1/3 of the daylight hours X the Amps.

Since you need the power for something important. I would get a car battery or rv battery and charge it at home like someone said before. A car Battery can have 100 Amps hours, that is more then enough power to last you a week camping. You can even take you car battery out of your car and use that and have your car recharge it.
Or you can get a bigger Panel.

And definitely not useless and its the future.
How is free power from the Sun useless.

If you solar power your house and your house gets good sun, you can have the system paid off in about 9 years. The panels would last over 25 years, but you will still have battery maintenance. Still you save in long run and its only going to get cheaper in the future.
I always like the security you get by not being dependent on the grid.

i chose the not ideal conditions to test my system because that is how it is used when im camping. ie the max number of sunlight hours that i have are from sunrise to sunset. thank you for point out that not all the hours are equal.

also, i chose indirect sunlight because when im camping i dont have time to be calculating and adjusting the angle of the panel to the sun. why? well i guess im too busy camping.

anyway, ive come up with my best solution without buying more equipment.
here's my solution:
1 - i used the car alternator to bulk charge the battery for about an hour. because i dont want the alternator to charge the battery at too fast of a rate, i use the 7amp charge controller( the one that comes with my solar panel) to limit the current.
2 - then i connect the battery to my solar panel and let the solar panel do the only thing that it is good at, ie trickle charge the battery for the rest of the day.
on a good day, the battery experiences a full absorption charge from the solar panel.

i also have a 2amp charger that plugs into a 500 watt inverter that i own. it too bulk charges the battery in about 3 hours. it is gentler on the battery. but it involves running the car longer than i like. h9wever, i do carry it and use it if im traveling from one location to another.

I haven't got a clue what you are talking about. Are you drunk again?

aww, got cross threaded. Sorry bout that.
Speaking of solar systems, I have the Tesla 2kva system.
It halves our power bill.
Here in NZ we pay 30.55 cents NZ per kilowatt hour +.33 cnets per day line charge, 10 bucks a month.
They buy back at 06.cents per kwh.
I read that Mexico solar power big thingy costs .02 cents to produce a kilowatt hour,
Int eh summer with long
Ontario its .09 cents per kwh.
We get ripped off here is the government flicked the crown jewels when they privatized 49 % shares in the power companies.
The baqttery on its plinth looks very futuristic.
The house draws power but shuts off at 30% battery level so ya got juice if the power goes out.
We can view our electricity draw on line and convert to a "smart" house.
We have had it for 3 months so still learning to drive it.'
Smart house jazz.

so how often do you get '2kva' from it? Around here that wouldn't power a toaster more than once a day.

your complete refusal to consider evidence is comical.

the world either fits your pre conceived ideas or - well, no or.

you know it all

Your reading comprehension is less than a child in grade 3. Go back to the OP.

I bought, it failed, I measured, and discovered that the product only produced 10% of what it promised. In the real world, that pretty sums up the definition of 'considering evidence'.

Not like you. All your evidence comes from the internet.

Canada obviously isn't a big problem!
