What technology and chemical serves the same function as chloroplast, other than solar panels?

Posted on July 25, 2011 by admin

What technology and chemical serves the same function as chloroplast, other than solar panels? Solar panel converts solar energy in to electrical energy and the chloroplast of a plant cell converts solar energy in to chemical energy. Is there any other technology and chemical that converts solar energy in to any other type of energy ?

solar heaters to convert sunlight to heat

What role does information technology play in the solar energy industry? and how is IT used in this industry?

Posted on July 20, 2011 by admin

Appreciate any information the areas in the solar energy production or solar cell manufacturing where IT plays a role? IT firms providing solutions or technology to solar companies or case studies?

Thanks.

Any manufacturing is going to need control of inventory, process control, and procurement of materials at best prices.

Large solar facilities will need to track the output of each panel and each inverter individually, or at least track groups of them, so that if something breaks, the company can go and fix it. They can also notice a slight percentage drop in output, possibly indicating that the panels need to be cleaned.

Selling the electricity is a financial transaction. The kind of bidding and selling that Enron did still goes on, but is more regulated now. As such, it’s the similar to a stock market, and lots of IT is needed.

How much energy in joules can the solar panel produce each day?

Posted on July 16, 2011 by admin

Suppose one square meter panel of solar cells has an efficiency of 30% and receives the equivalent of 4 hours of direct sunlight per day. How much energy in joules can it produce each day? What average power of watts does the panel produce? If the solar cells were efficient they would generate about 1000 watts of power per square meter of surface area when exposed to direct sunlight.

4 hours = 14400 seconds

1000 watts of power per square meter

1000 watts = 1000 joules per second
1000 joules per second x 14400 seconds = 14400000 joules
30 % of that = 4320 000 joules.

since this is joules per day per m², the answer is 4320 000 joules/meter/day
or 4.32 MJ/m/day

what will be the a few of sorts of solar energy systems?

Posted on July 10, 2011 by admin


there are presently three main types of solar power system: solar buildings, solar thermal concentration systems and photovoltaic.

Which is a better way to use solar energy, mass-production or individual home usage?

Posted on July 1, 2011 by admin

I know we need to put a ton of effort towards research in renewable energy, specifically solar. But when it actually becomes a viable alternative to oil, and we can ~store~ solar energy efficiently, would it be best put to use atop individual homes and buildings, or as a source of electricity for whole cities?

The biggest problem you have with large solar installations is finding a large area near a major population center. In many cases the town councils love the IDEA of solar energy BUT just don’t want the solar energy farm IN THEIR TOWN!

In terms of efficiency, a large solar installation is far more efficient than solar panels on everybody’s roof.

However in this case the Political decision ends up trumping the Engineering decision.

Can some one translate this please? and is this translation correct?!?! in french please!! natvie speaker!?

hey i want to say this

In our modern society we have the potential to use all different means of energy. In Australia it is a perfect country to use solar power! I personally do not know why it is taking so long for the governments to implement this. I would also recommend that you look into nuclear energy as an alternate means of power to supply the nation.

Even though nuclear energy is more efficient than the current usage of fossil fuels, we cannot debate that solar energy is the way to go. Even on a rainy day you will still produce more energy than you will consume. But honestly why not be self-sufficient? It saves your money and it saves the environment!

how i have translated it.
Dans notre société moderne, nous avons la possibilité d’utiliser tous les moyens d’énergie différentes. En Australie, il est un pays idéal pour utiliser l’énergie solaire! Personnellement, je ne sais pas pourquoi cela prend si longtemps pour les gouvernements à mettre en œuvre. Je recommande également que vous regardez dans l’énergie nucléaire comme un moyen alternatif d’électricité pour alimenter la nation.

Même si l’énergie nucléaire est plus efficace que l’utilisation actuelle de combustibles fossiles, nous ne pouvons débattre que l’énergie solaire est la voie à suivre. Même par une journée pluvieuse vous serez toujours produire plus d’énergie que vous consommez. Mais honnêtement pourquoi ne pas être auto-suffisant? Il économise votre argent et il sauve l’environnement!

please help =P thanks!!

Not bad . I had to change some expressions, grammar structures such as subjunctives and some words .

What is the future of solar energy’s technology?

Posted on June 26, 2011 by admin

I’ve been thinking about spending over $30,000.00 on solar panels for my house for a while because our electric bill is often $300.00 per month. But a construction worker who is friends with someone in the solar energy business strongly advised me to wait. He said that although the solar energy business has been around for 30 years, its technology is still in it’s infancy.

But because of increasing popularity, it is expected to become doubly as effective and cost A LOT less (if not half as much). But there are huge government rebates right now that will lower the price and I don’t know how long it will be until the technology advances come around.

My construction friend is suggesting that buying a solar panel today would be like buying a flat screen television when it first came out. They cost over $5,000 when they first came out. Now you could buy an ever better set than the one you bought only a few years ago for less than $1,000.

Does anybody out there have any inside information on the future of solar energy technology?

I don’t have any inside information, but that is the way technology works. Solar panels are not very efficient at this point and are quite taxing on the environment with their production. If you figure 5% interest, Just the interest will cost you $1500 pr year. That leaves $2100 per year to pay off the initial investment. It will take almost 15 years to pay off the investment. I don’t think they are cost effective at this time.

What energy conversion occurs when a solar panel uses light to provide power to a house?

Posted on June 24, 2011 by admin

A) Electrical energy is converted to solar energy.
B) Nuclear energy is converted to solar energy.
C) Radiant energy is converted to electrical energy.
D) Thermal energy is converted to electrical energy.

C – Light (Radiant energy) is converted to electrical energy.

What is the easiest and cheapest way to use solar energy in a classroom?

Posted on June 21, 2011 by admin

Hi, I’m doing a school project. We are required to design a classroom which exists in a "storage" container, with the idea that this classroom could host 25 learners and be self-sufficient so that it would be able to be used in rural settlements.
What is the easiest and cheapest method of using solar energy? The energy would only need to be used in winter for lighting and maybe a heater/radiator of some sort.
Ideas????

It is possible but very expensive to build a solar system that will make a room the size of a classroom "Self Sufficient" in winter period. May even be practically impossible if located where a lot of cloudy days are experienced.

At least the projects design and cost calculations may open your students eyes to the fact that Solar power is not easy and cheap like the news media likes to make us believe.

I have studied solar power for years. My first guess is you would spend over $100,000 and still not have a system that could support the goal of "Self Sufficient" unless class is willing to spend many days bundled up in freezing temperatures. May be possible in an area like Arizona or the Sahara desert.
