From LJ discussion:

> A manager that requires that besides doing my job I also teach him programming (e.g. explain why atomicity is important), and then comes with "brilliant" suggestions and/or more questions, is the worst kind.

Thanks - that is a clear explanation.
I strongly disagree with you on that and believe that you are making a serious mistake by rejecting people who want to challenge you and learn from you.
It hurts you in two directions:
1) You are losing the opportunity to test and clarify your mental models.
2) You are losing the opportunity to identify your selling points and practice your sales pitch.

Actually you are not exactly following your stated preference. You are teaching people and allow to challenge yourself.
You mentioned Monitor.Pulse() in this thread.
But you are doing only a half-assed effort in that direction. In particular, you chose to shut down the discussion when it hit the stage of an actual practical code recommendation.
You could show to me and to everyone who will be reading this thread that you are a closer who delivers practical solutions. But you chose to stay at a vague state of hinting that you may know something but not really proving it.
You chose to avoid getting your practical solution criticized (and therefore did not test and did not allow a chance of improving your tech skills as a result of that tech discussion).

I and best professionals I know - like to share what they know, and in particular they are eager to explain what their expert opinion is based on.

Warren Buffet - teaches his financial investments craft all the time.
Bill Gates shared his line of reasoning in a couple of books and multiple interviews.
The best performing air conditioner technician that I met - encouraged me multiple times to ask him questions and was eager to explain how air conditioning works, what to do and what to expect.

That story repeats over and over again.

I myself encourage people around me to challenge what I know and am eager to teach what I know: business, technology, politics, sales, social skills, etc.

I strongly encourage you to do that yourself. It will turn your life to the better.

I Just had the solar panel salesman over my house.
We talked over 3 hours.
He told me that his usual appointment is about one hour, and usually he is successful at selling.
He told me that he usually have 3-4 appointments every day and he sells about 2 times per day.

With 5% commission and $30K average sale price he makes a lot of money. You do the math.
Well, I think he overestimated it a bit, but it's still a lot.

BTW, he pays to the guy who setup appointments $40 per lead.
So, assuming I do not buy from him (which is likely, but not definitely), he lost $40 and 3 hours of time.

Now, back to solar panels benefits for me.
To simplify, according to his calculations, if I get a 12 years loan for 100% of sale price and then use 30% tax rebate from the government, then my loan payments would be about the same as my current electric bill savings.

So, for example with solar panel that would cost me $150/month monthly payments on the loan, I will cut $150/month from my electric bill.
Due to 3% inflation electricity price is going up about 3% every year. But my loan payments would stay fixed.
And after 12 years, when I repay that loan, I would have to pay nothing.

Another interesting benefit the salesman told me about is that string converter works with solar panel has batteries that keeps electricity for couple of hours.
Sounds like Uninterruptible power supply to me.
I wonder if it would actually be able to maintain power for 2 hours.

The salesman told me that since roof on my house does not have any shades, I should use string converter (instead of microconverters that are beneficial if solar panels have varying power output).

The price for 7KWatt converter is about $25K with installation (2.5 times higher than internet price without installation).

I do not want to install it myself, so I would need to find somebody to install it.

Update 1:
The salesman claimed that solar panel installed on my roof would at least keep its value if I would try to sell my house (30% tax rebate would help).
He also claimed that in California these solar panels even increase house cost by more than they were bought for.

Just got sales guy from
He's selling solar panels to our roof.

The cost is about $20K...$30K depending on our electricity needs.
Zero money down, 2.99% financing for 10 years.
30% IRS tax credit.

The homeowner soon discovers their alleged energy cost savings are nowhere near that which was promised. If the homeowner refuses to pay on what is now an upside-down lease, they learn for the first time that the solar profiteer placed a lien on their home – a lien that impairs the customer’s ability to sell their home and that forces them to continue to pay under a bad contract at fear and risk of potential foreclosure or other legal action by the new holder of the lease.

Besides, energy prices (oil and gas) went down significantly, so it makes solar panels less attractive.

What do you think: should I install solar panel on the roof of my house or not?

Update 1:
Another article and discussion with pros and cons:

Update 2:
Vlad Turchenko recommends (on Facebook) this solar panel:
7000 Watt (7kW) Complete Solar Install Kit w/Microinverter

It's a very valuable lesson for everybody: salesmen, buyers, and shareholders.
