Q:A good brand of solar panels for my house?
You don't say what you are doing. Are you trying to get electricity from them and need solar photovoltaic panels or are you trying to run a heating or hot water system and need solar thermal panels. It is unfortunate that both of these are known as solar panels as they are really two entirely different designs. Currently the solar thermal panels are more efficient and therefore have a quicker pay back period usually measured in lower single digit years while the photovoltaic panels have paybacks that are sometimes more than double that unless you figure in increased property values and state and federal subsidiaries and tax credits where available. Edit: Recent advances make any current investment in photovoltaic panels likely to be obsolete in 5 years. Still someone has to be on the cutting edge. Two currently available technologies are concentrating the sun's rays within the collector on a much small chip area.2 This improves the efficiency and lowers the cost as concentrators are cheaper than chips. The other option is newer chips that accept a wider spectrum of solar energy.3 This has the potential advantage of producing more energy on cloudy days. This may not be so important in your situation. Balanced against cutting edge technology will be the possibility of getting older panels at a less expensive cost. The bottem line will always be pay back period. More panels at a lower efficiency and cheaper price will be just as good as high efficiency at a higher price if the numbers work out. 4 Between two answers here you now have a criteria for selection and some recomendations. Good luck with your project.
Q:What is a solar panel?
Solar panel is a battery of solar cells. Solar cell is a device which uses the sun's rays to produce electricity by the photovoltaic effect. The photovoltaic effect involves the creation of a voltage (or a corresponding electric current) in a material upon exposure to electromagnetic radiation. It utilizes the generation of a voltage when radiant energy falls on the boundary between dissimilar substances (as two different semiconductors).
Q:DIY single solar panels with outlets?
Build okorder.com
Q:Is this a good kit for building a solar panel?
I okorder.com lower right corner is home built solar panels
Q:Is photovoltaic array another name for solar panels?
Here's solar photovoltaics: They not only look different, they act completely differently!
Q:there can i get dc solar panels for out side lights?
They make lights that have solar panels built into them. Due to the solar cell, they can sense when it gets dark and thus switch on the light automatically. Look at Northern Tool or Harbor Freight web sites for ideas.
Q:Choosing right wattage solar panel?
o work out the wattage correctly, the panel needs to be sized according to how much power you are going to use. (Later on you're going to need a bit of info on each electrical item you need to be solar powered).
Q:installing solar panels on roof?
Biggest problem is availability of sunshine in the UK. Do you get enough to warrant the fuss or financial layout? Another problem is the orientation of your roof. Facing directly south, with a slope (in degrees) equal to your longitude would be ideal. As far as electricity goes, you have to be tied into the grid to take care of the times you are not generating all the power you need. When you are generating more than you need, you sell it but get paid at the rate the utility normally pays, a lot less than you would pay to buy from them. Still, it's something.
Q:Where can I get free solar panels?
I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
Q:How I can get 300- 500 Wh of energy using Solar Panel?
As in the reply to the other version of your question - you should be able to get that wattage much of the time during full daylight from the area you specify, but your location, weather, and ability to mount the panel(s) at the best angle to the sun at time you most need the energy (winter? summer?) Instead of going with guess work on the efficiency of the panels you are considering, the people who want to sell you panels (or their website) should be able to tell you from the angle of your mount (roof?) and location, etc., an estimate of the average and maximum power available and the kWH during various seasons. This has to be known for either buying the batteries for storage or knowing the economics of feeding back into the grid, depending on the method used.
