Q:How much energy would this solar panel produce?
The world record efficiency for a solar panel is about 42%. At the equator, you can get up to about 000W m^-2. The efficiency of commercial cells tends to range from 0-20%. They're almost all single junction cells, so will never exceed 3% efficiency. To work out your maximum power output, multiply 000 x efficiency (as a decimal) x area covered. So an 8m x 0m solar panel would be 80 square metres. At 5% efficiency its peak output would be 2000W or 2kW. Total energy output will be different, since it won't be maximum power output all the time. In fact, it will more likely generate something like 20% of its maximum theoretical output, since the Sun won't always be overhead (and sometimes it's night!). The 2kW panel above might have a mean output of 2.4kW, or 57.6kWh/day.
Q:Is it worth getting solar panels fitted on my roof?
In 2007, the cost of solar photoelectric power was 38 cents US per kwh while the cost of coal power was 0.6 cents per kwh but consumer costs for power were 2 cents per kwh as additional coal power plants are not being built so wind and natural gas are being built. Without government incentives, solar power are not economic. However, the UK has extensive subsidies for solar, I would suggest that you learn how to perform Internal Rate of Return ( IRR ) calculations and Net Present Value ( NPV ) calculations to evaluate your financial decision, excel has an excellent =XIRR() function to do this with. Most people talk about payback periods but that's due to the poor level of financial education in the population and payback periods don't give you an appropriate evaluation of the time value of money. With solar power, it's a razor thin line of economics so you have to get the calculations right to know what's in your best interest, the laymen hearsay isn't going to do it.
Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
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:Solar panels?? I need help!?
Solar panels are a great way to cut back on your energy bill. Once you are hooked up to solar energy, the home owner does absolutly nothing different than if you buy electricity from the power-company. Sinse you live in texas, it is more than likely you will not be able to use purely solar power to meet your energy needs unless you purchase a large system ($30,000+). However with enough of an investment, you can 'Sell' your energy back to the power company and greatly reduce your electric bill. I would call a licensed Solar Power company for more information if you do not know much about solar. While the system is relativally simple, it should only be designed and installed by trained licensed professionals.
Q:How may solar panels/wind turbines may be made affordable?
go okorder.com/ they sell books on how to build solar panels and wind turbines, along with a lot of other things that could help you live off grid. And a lot of the books were things that could be made with turn of the century (900 not 2000) technology
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:pool leak solar panel?
If you do not isolate the solar system when backwashing your filter, you WILL pump DE into the panels and plug them and destroy them. At this point you may have to disconnect the panels, wash them from the RETURN SIDE (from the higher pipe and HOPE that the DE will flow out of the panels... most likely your pool guy just screwed up your solar real good... if the DE is plugging your panels, when winter comes your panels will split because they are holding water and the freezing water will split them... I hope your pool guy has insurance
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
