Q:Kwh and watt conversion-- solar panel cost?
It is easier if you will going to visit a number of solar panel company just to be sure that you have the right values. Some of them will give you a free solar panels quote. Compare and select options that will best work for your home and budget.
Q:List of new solar panel manufactures?
you won't be in a position to purchase at that point except you're related to governement. a lot of manufacturing is already spoken for for years yet to come again. the place you reside determines what you may legally purchase and installation. the ecu has this is own certification, the U. S. has 2 gadgets, the Canadians have their own. Your answer additionally demands understanding the use for the photograph voltaic panels, despite if it extremely is grid-tie, off-grid or standalone to skill an equipment. and additionally you may desire to choose for mono crystalline, poly crystalline, or skinny-action picture.
Q:Why do solar panels burn out?
They are used in an environment that's very harsh for semiconductors, especially the high temperatures. Ion migration and many other failure mechanisms increase with temperature. Thermal expansion adds its own mechanical stresses.
Q:can i make a solar panel out of aluminum foil?
You can't make a solar panel to generate any reasonable amount of electricity from that. You need a semiconductor to start with, in order to have something that can generate free charge carriers(electrons and holes) from photons. Then you need a junction which can separate the charges. In principle you could make a Shottky Diode solar cell from copper if you could find a doped semiconductor to bond a sheet of it to the copper. To form a decent electric field there should be a significant difference in work functions between the copper and the semiconductor, this will generally require the semiconductor to be doped. On top of this you would need a transparent conductor (most used are things like ITO or other 'TCOs' - Transparent Conducting Oxides) to be the top electrode to inject replacement charges into the semiconductor to replace the effect of recombination current. In summary, it's difficult to DIY. You generally need complicated machinery to get decent crystal growth and/or doping.
Q:Increasing Solar Panel Efficiency?
Even the angle of a solar panel can increase it;s out put, if you point it towards the south, it will receive more light (or towards the light source if it is an artificial source) mirrors can also be place and angled around solar panels to gather and reflect more light to the panel, this is often done is solar water heating, but would work with a panel as well. Over all, solar panels are very efficient, it's our way of catching light that isn't.
Q:How to charge a solar panel?
Just to clarify the terminology here, solar panels can be used to charge batteries. The solar panel produces electricity from the sun but you do not charge the solar panel. So I'm assuming you have 3 .5 volt rechargeable batteries connected to a solar panel in some kind of integrated unit. The batteries are probably wired in series giving you a 4.5 volt output from the unit which you can use for powering LED's, portable radio etc. The solar panel may have about 2 solar cells wired in series, each producing up to 0.5V in good sunlight, but the amount of current they produce depends on their physical size, the sun's intensity, the load being supplied, and the type of solar cells. If it has the cheaper amorphous silicon solar cells, they will actually produce some useful output on cloudy days and charge your batteries slowly. However if they are more expensive crystalline cells they will only work with good sunlight, but then they will work very well and charge your batteries relatively quickly.. If your batteries are not charging enough on a cloudy day you could connect a mains-powered 4.5V charger to the output terminals of your unit. However you may need technical expertise to make this work because of the possible presence of internal blocking diodes. You also need to ensure the mains charger has appropriate power ratings and the connection to your unit is made safely, + to + and - to - . I hope this helps.
Q:solar panel for computer?
Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:What are solar panels made of?
photograph voltaic panels take power (and in all probability some oil for the plastic) to fabricate, yet that power, and the carbon footprint, is paid for many circumstances over in widespread operation, via the electrical powered energy that the panel generates. The life of the middle photograph voltaic cells is long (there are nonetheless some panels from the 970's that are nonetheless out and dealing), and contemporary panels are oftentimes warranted for 25 years, showing that even the manufacturers have self assurance in thier lifespan. yet whilst it ultimately comes time to eliminate the panels, the aluminum physique is as particularly recycled as the different aluminum, and the tempered, low-iron glass could properly be recycled, too. The plastic substrate is unavoidably solid - it has to stand up to the solar for some years. i do no longer understand what could desire to be achieved with that. The cells themselves are a intense grade of silicon, which has fee on the scrap industry. some panels are no longer made up of silicon - yet lots of the factors could desire to be recycled in a similar fashion. i'm no longer attentive to any intense panels being dumped or discarded at present. they're worth lots, even broken, that some hobbyist or surplus place will purchase them.
