Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
Q:Solar panel wiring trouble.?
Q:Solar Panels heat absorption?
Solar photovoltaics require light, any kind of light. A torch would work, for example. The effect of concentration depends on the amount of light and the material you're shining it on. In CdTe, warmer temperatures and more intense light may lead to better performance. In silicon I think the opposite is true (I don't know though, I've only done research work with CdTe). It depends on properties of the semiconductor, like its band structure. To get an 'order of magnitude' estimate, you may assume a constant efficiency of solar cell so total amount of light (= area * intensity) largely determines the output in standard operating conditions.
Q:80 watt solar panel ? what dose that mean?
Caykay, Your question is amazingly great and obscure so that's perplexing to respond to. photograph voltaic panels are designed to value DC batteries, so which you will would desire to alter your electric powered gadget to paintings with DC. So, your quesiton isn't that straightforward to respond to. you will desire to start on your very own examine to get to a useable prognosis / answer. you will desire to renowned what a watt is and an amp is. you will desire to renowned what the cost of a kilowatt is to confirm what proportion watts you utilize in a 300 and sixty 5 days. then you certainly can start to estimate what proportion photograph voltaic panels you want. you do no longer throw away photograph voltaic panels. this is the component of them. as quickly as bought, the capability supplied for years is considered 'loose'. the place you reside has alot to do with it too. Sunny Arizona, or Florida are great and could require fewer panels than different, extra cloudy places. expenditures and structures are complicated, yet obtainable to be researched on the information superhighway. you could touch broking / distributors and that they're going to clarify it ot you. superb to you.
Q:why wont my solar panel make my dc motor work?
A 2V battery designed for a current max of 200mA, can turn on a 2W lamp. If you want to turn on a 2V 200Watt lamp, you need a bigger battery capable of providing 6 amps!! Similarly the solar panel you have can produce a voltage, but when connected to a motor, the voltage might drop to much lesser value!! So apart from voltage you also need to know current taken by motor. Further, motors have a habit of not starting, but once prodded (mechanically rotate the shaft with hand), they may run. If you are in that border area, give a turn to the motor and see.
Q:Advice on Solar Panel....................................?
Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:how often do you have to replace solar panels?
I have several friends that have large systems down in Mexico where there is no electric grid. They have had these systems for years. They say you probably should plan on at least 0 years with decent output. The capacity does taper off with time so maybe half power in 5 years might be a good assumption. Here in Arizona our payback (Break even) point is about 8-9 years. Our state has subsidies along with fed, and utility company. A 3000 watt system will cost about $0,000 installed. That is about half off regular price.
Q:Why are solar panels still so expensive?
Photo Notice it costs over $200 and it takes up a sizable amount of space. Plus you have to expose it to bright sun light. Over all this is not something the average consumer wants to spend money on or fuss with. If something is expensive, difficult or inconvenient to use then people won't use it. Just the basic economics of such a device limits its sales never mind its functionality and usability. Even if you made a small one buit into the cover to extend the battery you won't get much of an extension and you will increase the cost of your laptop. Consider how people shop, will they buy the more expensive laptop for a questionable amount of battery extension? Mass production can lower costs but in order to mass produce something you need a demand that will consume what you produce. But if no one wants the item because of the aforementioned issues than you can't justify mass producing the item. This is like the classic which came first Chicken or Egg problem, one doesn't happen without the other. Cost reduction doesn't happen without consumer demand. This is where tax incentives, subsidies, low cost loans and energy buyback contracts come into play in order to spur on demand and jump start mass production. You could also make electricity extremely expensive by taxing oil and carbon so that a Solar Cell becomes economically competitive to very expensive electricity. Problem with this option is the negative impact high energy costs have on economic activity. Just look at what happened a couple of summers ago when gas hit $4/gal. To spur on demand we need to incentives the use of Solar cells (and other alternative energy). This can be done through several means such as subsidies, tax incentives, low interest loans, energy buyback contracts etc...
Q:How do I get a grant passed for my school for solar panels?
Excessively long payback schemes for solar panels are being quoted. It depends on where you live, where you situate your solar panels, what you buy and if you get a grant or install them yourself. Much of the cost of Solar panels is in the installation. Any competent DIY person can install a simple solar panel system. Ours cost less than £000 to buy and self install. What are you calling payback time? Because each time I don't use fossil fuels and use solar energy instead, I don't get a 'fossil fuel' bill. Whilst we still use some electricity for running a fridge, lighting etc we have no other fuel bills, no gas, no oil, no electric heating no electrically heated hot water. We have woodburning stoves (which run on free wood) and solar. Remember you are not just paying for the electricity/gas/oil etc that you use, you are also paying standing charges, VAT etc. Include those in your 'payback time figures' and you will see a very different picture. How long would it take you to pay back £,000 if you only had one tiny electric bill each quarter?
