- Q: Is it really possible for me living in Denver to build and install and setup my own solar panel to help make electricity for my home?
- It's okorder / has something to say about various scams, including solar.
- Q: What are solar panels?
- Solar panels are a collection of photovoltaic cells, that are used to generate electricity, from light. Here is the simple explanation from wikipedia, concerning photovoltaic cells . Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. 2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel. 3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity. Solar panels are used extensively for power generation in many places, but most space applications (like satellites and spacecraft) use solar panels. If you look at a picture of the current configuration of the International Space Station, the giant wing things are the solar panels.
- Q: What is the average payback period for solar panels?
- The average payback period for solar panels is typically between 6 to 10 years. However, this can vary depending on various factors such as the initial cost of installation, location, energy consumption, government incentives, and local electricity rates.
- Q: do solar panels create electricity from the ultraviolet light created from the sun? because they only have an efficientcy of like 8% and this scientist found out a way to collect the visible light also, and he says the solar panel could have an effeciency of up to 80%! so my question really is, do solar penels creat electricity from heat? do you know of anything that can?
- Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
- Q: looking for a solar panel to charge my laptop on the road, macbook is 60 watt 6.v 3.5a, what should i be looking for in a solar panel?
- Well that's a good idea,,,here's what ya need..First you need an array that will overcome the drain effect created by the in use or sleeping laptop...that is best solved by averaging out the real use of the machine in terms of watt/minutes...If you check your transformer you'll see it has a capacity which you have cited however the true use of the computer is about 40-50 percent of that in watt/minutes..but only while your using it and when in the sleep mode the watt/minute value drops even more to about 5%.... So if your actual use consists of 2 hours of use per day at 50% and 2 hours at 5% percent the actual wattage draw is only averaged out at 34watts/minute. optimally your panel should supply all your power from its photovoltaic conversion ,but in the real world application the panel only recharges ,over a period of time, the used power. So if you had a 5 watt (@ 2vdc) panel working 480 minutes and used up 35 x2=700 and 9 x2=8 for a total of 78 watts you would have 5 x 480 = 7200 watts input and a parasitic load of 78 watts in the two hours...well within the recharge state required.. For a little safety I would permanently wire a cigarette lighter type plug to the end of the panel this will keep the polarity correct and serve as a quick disconnet means...Also add a fuse at .5 amp... a good place to get these are on the internet....some are very expensive some a very cheap --go for a middle of the roader...Have a good one from the E...
- Q: What is the warranty on solar panels?
- The warranty on solar panels typically ranges from 10 to 25 years, depending on the manufacturer.
- Q: All I want to power is a small ice-maker (250 watts) for 25 minutes per day. That's all!!!Can I do that by using a 00 watt panel with 2-3 deep cycle batteries and getting 0 hours of quality light per day.(BTW) what size converter would you recommend? I want more than I need to grow the system
- If okorder and they ship across the US and Canada.
- Q: I have had this 2v portable Solar Panel for my apartment for awhile. Only problem is that I have no balcony and I can barely get enough sun to use it with my Cobra 450 400-800 watt outlet converter. Can someone advise me a better method to use these? Like do I have to get more 2v solar panels? I have a small apartment and use it on one window. Also is it possible for me to buy a portable storage tank to store the energy gathered from the sun by the solar panel?
- portable storage tank would be lead acid batteries. Use only marine sealed type for safety, about $300 each. You will need a charge controller to control the charging of the batteries. If you don't get enough sunlight, then the only alternative (aside from using the roof) is to get more panels. .
- Q: Can solar panels be installed on a stadium or sports arena?
- Yes, solar panels can be installed on a stadium or sports arena. Many stadiums and sports arenas around the world have already installed solar panels to generate renewable energy. The large roof spaces and ample sunlight exposure make them ideal locations for harnessing solar power.
- Q: a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
- This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
