Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
Have okorder.com . It may extremely teach everyone!
Q:Solar Panel Installation?
Wires from panels go to controller input terminals. Controller DC battery terminals to battery so that the controller will protect batteries and split power as required by demand to the inverter. Output DC on controller to inverter. Output AC or outlets on the inverter to AC appliances. One thousand watts is not very much capacity. It will keep your computer running and a lamp to read by. It won't run major appliances. A hair dryer is typically 500 watts and could not be run by this system.
Q:solar panels on housing developments?
Because not only does that just make TOO much sense, it comes down a cost factor, even though, as you say, what's another couple K for saving the environment. Sad thing is, even though they *JUST* figured out that global warming (loved that news story a couple weeks ago) is caused by humans abusing the earth, Americans especially just don't care enough. Our culture is so spoiled now that we refuse to be told what we need if it's not what we want or if it will cost us $5 extra.
Q:how to power a 400 watt heater with solar panels and batteries?
well, you need to produce 3200 watt-hours per day with your solar panels how many you need depends on the type of panel and size and how much sun you get (the energy of the rays depends on your latitude and the time of year) the amount of batteries you need again depends on your requirements and your insolation if you only need to heat when the sun is shining then you don't need any batteries at all if you want to heat for 8 hours after the sun has quit shining then you obviously need batteries to hold 3200 watt-hrs of electricity to actually size a 3200+ watt-hr solar system you need a lot more information
Q:how much solar panel power do i need?
My guess is that you might discover everything concerning solar power at www.okorder.com.
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:Why can not the solar panel load directly?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:Solar panel wiring, materials?
the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel
Q:Solar panel for macbook?
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:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
