Solar Electric Energy Systems - You Are Going To Be Amazed !
Author: Jason Gilford
It's like this - most people expect the electric company to supply their electricity; they pay their bills month-by-month and often have to economize elsewhere in order to have something like electricity. However, there are the lucky (or smart) ones who found an excellent alternative; they were tired of spending their income on a natural resource - they discovered a way of generating their own power - as much as they want - and would meet their current and future needs.
So while investigating more about solar electric energy systems be sure to consider the real possibility of starting your own energy generating system; actually you can enjoy this [POST CONTENT] cost power supply in just few days from now - all it takes is a desire to save money! So you're probably eager to get in on all the details as to how this can be achieved; it happens to be a simple matter of converting renewable energy sources that are right 'under our nose' into free electricity. Do you know that it's possible for anybody to construct a personal energy generator using sun and wind power in several days without needing outside help?
Although you might just be starting to look into solar electric energy systems you should understand that you can quite easily build a system to harness the power of the sun and wind that can actually decrease your electric bills by as much as 100%! Perhaps this sounds like too much to take on all by yourself; just recently the whole thing has gotten much more accessible - fortunately for all of us, a well-respected expert in the highly specialized field of renewable energy discovered a way to make this accessible to anyone.

What is the difference between “thermic solar energy” and “electric solar energy”?
What is the difference between “thermic solar energy” and “electric solar energy”?
thankyou
how can i use solar energy as electric energy?
I want to use solar energy at home.
Consider using solar lighting which can be cost effective introduction to solar power. Kits are available with solar panel, regulator, lights, battery, switches and cable. Other DC devices can be run from the battery.
I have used solar panels to maintain charge in batteries for standby generators.
Solar power can be connected to a grid feed inverter to save on power bills or earn money.
Consider what free electricity from the sun for 30 years is worth.
Normally I see this when discussing the difference between Photovoltaic (light electricity) solar panels and thermal (heat) Solar Panels. Solar thermal is the more mature technology with photovoltaic as a relative newcomer.
There has been an explosion of research in photovoltaic solar in recent years. Most is using visible light and efficiency has been slowly creeping up to around 40% presently with projections around 60% although what you can buy is probably around 15%. But the light that we can see is only part of the energy spectrum. Work is being done to try and capture other parts of the sun’s rays that are not visible. Even if they are less efficient they will be drawing from a bigger pool.
Solar thermal applications also convert the suns rays but in this case to heat. The efficiency is about 60% to 80% and includes both visible and non visible light. Thermal solar applications usually place more emphasis on concentrating solar energy with mirrors on to a target or within a medium like water or some salts.
Solar thermal panels can heat air within them or water that flows through them. In each case there is a target that conducts heat to the medium. The latest advance in solar thermal panels are vacuum tube collectors. Often these use phase change materials and a vacuum in a tube to collect more of the sun’s heat in cold environments and on cloudy days.
A greenhouse or a sun room is a solar thermal application as are windows placed on the sunward side of a house. Most commonly solar thermal is used to heat water or for space heating where it matches well with radiant floor heating but needs some thermal mass for storage.
Solar thermal applications can be used to run air conditioning using an absorption system for refrigeration.
Solar thermal applications can also produce electricity. There are three main designs: A power tower where a target is centrally located and many heliostats (mirrors that track the sun) focus sunlight onto a target. The steam produced might then be used to power a steam turbine. A hyperbolic mirror is used to power a stirling engine. This has an advantage of a potentially smaller scale. And last the trough collectors that focus light in the trough to central piping that is used to power turbines.
Do you think the economy and government will stop using gasoline and start using electric and solar energy?
I think we should start entering a new era of transportation and be more health wise with our atmosphere. That is my opinion.
Definitely not in the near future, despite of what Bush and everyone else would lead you to believe… First of all the oil companies won’t let go of their monopoly till they run dry, 2nd of all there is no one focused company that is working on alternative fuel to be used as a mass product. Everyone is doing their own thing, Toyota is playing around with hybrids as is Honda and some other Japanese manufacturers, then they also dabble in hydrogen as well. German engineers seem completely lost when it comes to electronics and hybrid vehicles, so they rely on diesel and biodiesel. New Mercedes are being developed that will have both diesel and electric motors, which is awesome, but expensive, and highly unreliable. Diesels run very high pressures and use expensive parts like turbochargers, while electric motors got their own problems, like batteries, etc. Not a great idea to put them both in one car. On top of that it’s the car manufacturers who are doing all this, not the companies who will be selling the fuels, so the car companies won’t be making most of the profit, which makes means they are not funding these projects to the fullest. There are more reasons of course, but the thing is that we need to narrow down the alternatives and pick one or two fuels, then pool the available funding in that particular area and get some results. That way when there is a viable alternative further research can be done if necessary at whatever pace desired.
first why do you need sound the world is too noisy anyways. when I’m riding my bike I check the mirror every 20 seconds so why can’t everyone else. second probably 75% of the population drives less than 50 miles a day in their commute so an all electric is perfect for them. A pulse charger can charge a lithium ion battery in 20 minutes, and there not that expensive if you know where to look. I bought a container of 200 LI’s 300AH 24v from Hihon corp in china a few months back for 10k including shipping about $50 a piece. I finished converting a 85 dodge Omni for the wife. I just started an 86 Fiero for me, next will be something for my son, daughter, and son-in-law, and I’ll still have enough to do another 20 cars plus replacement batteries. and as already stated solar is fine for a house supplemental system, I have 10kw on the south roof of my house as well as 4 vertical axis wind turbines on my garage roof. but neither will work on a car. Electrics are small and light, they can’t be large trucks but bio diesel is renewable and relatively clean especially if they make up a small percentage of the vehicles on the road.
I’m keeping my gas and diesel cars and trucks I just won’t drive them around town when an electric will do.
Does a solar electric (PV) system consume more energy to manufacture than it will produce in its lifetime?
I’ve seen several discussions on blogs regarding the net engergy gain (or loss) of solar systems. Some people claim it’s a net energy loss, but I have a hard time believing that to be true. Can anyone answer with either a credible source or facts that back up their answer? I’ve done a lot of searching and found very little to help me clear up this question. And please don’t mix financial information into this discussion, I’m only interested in the net ENERGY of solar electric (photovoltaic) systems.
It is not simple to answer.
there are several different technologies
and many differnent working environments and load factors.
high-spec NASA pannels, clean room semiconductors, redundancy & destructive testing. and a short hostile life generating little useable power – perhaps the case could be made the are a net energy loss.
organic (dye) photovoltaics, although having lower efficiencies, are much simpler to mass produce, so less net energy input
and in normal use should give ample life to give a positive energy gain. unfortunaly still very much at development stage so no easy to read summaries
What are disadvantages and advantages for electric cars, & solar energy cars?
