Joseph asks…
I am thinking about getting into solar Panel sales but I do not know too much about it. ?
l am looking for information on it and have found allot but really I am looking for information on regulation, pricing, how much is necessary to generate enough energy for the average home ect.
answers:
Do a google search on solar-power, then refine your search using the ‘search within results’ feature at the bottom of the returns page for books.
Once you’ve found some interesting ones, go to Amazon.com & see if any used ones are available, or, if you live in a large metro area, check out your library. You could also get your library to get you the books thru their inter-library loan program.
Don’t know about any regulations, but many states offer tax breaks for installing the systems.
Good luck…

Investing in solar power worth it?
I got a brochure from my electrical company in the mail. It says that if opt to install solar panels for $2990, I get 66c for every kW it makes and exports back to the energy grid. It says that it’ll have paid for itself in 2.5yrs. The solar panels come with a 25 yr warranty.
It sounds like if I install the panels, I’ll get back my money in 2.5 yrs, and keep on making a profit for the 22.5 years that come after that. Has anyone tried this, and are there any hidden fees or information I’m missing?
answers:
Hi there
I recommend you get more information. It takes more than 2,5 yrs to make your profit back.
I your case I would get some guide be for investing.
It can be there expensive to obtain a solar power method installed by a trained, but you can organize it by hand and save many of money on installation on the start and stylish the slow run on energy bills.
Present are three options representing do-it-yourself solar. The principal of these is retail a solar power method, quick to install. The minute, a lesser amount of expensive option is to believe a solar power kit and place it calm on your own otherwise installing. The third, and by far the mainly cost-effective, option is to build your solar power method from cut.
If you pick the third option, the principal fad you need to organize is believe a program of easy-to-follow strategy, counting sufficient of expedient hints and ideas representing getting the mainly away of your just starting out method.
This option is the most excellent fine if you’re really into do-it-yourself projects and obtain the period to place stylish. It command take a quantity of effort but, after you’re completed, you’ll obtain the satisfaction of a career well completed and you can paddle by hand on the back all month after you realize how much you’ve saved.
An added benefit to retail strategy to build your own solar power method is to you command be there able to reimbursement the lowest achievable outlay representing all solar panel – quite a wide benefit!
By installing your own solar power method, whichever method you pick, you command be there significantly decreasing your carbon footprint on the planet. Solar power doesn’t pollute the air, ground or else irrigate and it renews itself all single daytime, the jiffy the sun comes up – even after it’s uncertain.

Challenge question?
Modern solar panels are approximately 10% efficient. That is 10% of the energy in sunlight striking the panel is actually converted into useful electricity. During the day, approximately 2.5×10^27 photons of visible light strike a square kilometer of earth every second (1 photon of visible light has an energy of about 4×10^-19 joules).
The Watt is a unit of power. 1 Watt is equal to 1 Joule per second. A 100-Watt light bulb therefore requires 100 joules of energy per second to stay lit.
Based on this information how big a solar panel (in square meters) is required to provide 350 Watts of electric power on a typical day?
I got 35 square meters but its wrong. What do you get?
answers:
Let’s see…the way I solved this problem is as follows:
Converting photons to Joules:
2.5*10^27 Photons/sq-km * 4*10(-19) joules/Photons =
1*10^9 Joules/sq-km
Converting sq-km to sq m,
1*10^9/(1000^2) = 1*10^3 Joules/sq-m
Introducing Efficiency factor (10%)
1000 Joules/sq-m * .10 = 100 Joules / sq-m (usable energy)
All of these calculations are done on a per-second basis.
So, for a 350 Watt (joule/sec), determine the area
350 (joules/sec) / 100 (joules/sec(sqm) = 3.5 sqm
So you are off by a factor of 10.
Hope this helps.

Solar panels are the way to go. We all need to do our part to spread the word. It’s just about getting the word out that solar and going green takes the same effort.
