Here is why the US & India should stop making low grade solar cells.
China makes the largest amount of solar cells.
This is good.
Instead, of competiting, companies should buy the high quality cells made by Germany & China, until the US can learn how to make better quality solar cells.
The US should not try to re-invent the wheel.

Apple computer had a genius leading its company.
Steve Jobs saved Apple from bankruptcy by inventing
the I-Pad, I-phone & I-pad.

The US solar industry needs a few geniuses like Steve Jobs.

China has more people on the genius level
than the US, because China has a centralized
education system that can train higher grade people
than the US can.

How can the US ever catch up?
First, the US needs to cut the Pentagon budget by 95%, use the money to fund colleges & pay students to become engineers.
We need 50,000 new solar engineers every year.
Let’s build a “Manhatten Project for Solar power.
That means training thousands of solar engineers today.
Hopefully, we can find a few genius level thinkers
to guide our corporate policy.
Apple had Steve Jobs. When he was fired, the “suits” running Apple ran Apple into the ground.
Jobs came back and saved Apple.
Why? Because he was a genius, and he proved he was.

The US needs to find a new Steve Jobs for Solar.

Here is a candidate:
I have a friend who installs solar panels on RV vehicles
for a living.
He makes $70,000. a year, above costs.

If you want a job, this is an easy job to start.
All you need is to solarize one RV your self,
just to prove to people you can do it,
then sell it on Craig’s List.

Why pay high labor costs.
Do your own work. Start your own career in solar.

It is so simple any high school student can start
their own career doing this solar work.

You can build an electric car charging station
with just 36 deep cycle marine batteries
wired together in parallel,
powered by 10 solar panels.
Start your own business.

You just install 4 deep cycle marine batteries
in the RV, in parallel, then you never need to hook up
to an electrical plug-in again.
Get a reastat.
You are off the GRID forever.

Do you know how to use pliers, wires & a screw driver?
Start your career.
Everyone should write a letter to their Congress person,
to oppose tariffs.
Only corporations will benefit from tariffs.
We need cheap solar cells from China.
Putting a tariff on solar, would be like putting a tariff
on Henry Ford, just because Ford invented mass production of cars.

We need open trade with China & Cuba.

Henry Ford stood up against tariffs.

Even tho solar panel prices are falling every month,
you should still install solar now, because the panels
will last you 30 years and save your hundreds of dollars a month
as you charge up your electric car.

Here is why the US & India should stop making low grade solar cells.
Instead, everyone should buy the high quality cells made by China.

India may jump into an escalating U.S.-China trade fight over solar energy as local manufacturers lobby New Delhi for protection against imports from rivals including First Solar Inc. and Suntech Power Holdings Co.
India may initiate an anti-dumping probe in a month focused on imports of Chinese solar products, China’s Commerce Ministry said in a statement yesterday. India’s Commerce Secretary Rahul Khullar declined to comment in a phone call.
Indian manufacturers are also seeking a 15 percent tariff on imports of thin-film solar panels, the country’s Renewable Energy Ministry Secretary Tarun Kapoor said in an interview. The biggest thin-film panel company is Tempe, Arizona-based First Solar.
Indian suppliers such as Tata BP Solar India Ltd., Indosolar Ltd. and Moser Baer India Ltd. have failed to benefit from a rule intended to spawn a domestic manufacturing hub in one of the world’s fastest-growing markets.
