Q:Should the value of solar panels be included when appraising a home?
Zillow appraisal is useless and not at all important. If you are selling your home then the solar installation should give you some advantage, depending on how much you are still paying for utilities. The only appraisal that matters is the one a buyer gets to lock in a mortgage. Nothing else matters.
Q:is my solar panel big enough?
A equipment that super could have a max power production of around 2000 watts. i won't be able to declare if it fairly is sufficient to your desires via fact the figures you gave do no longer make experience. right here is why: the quantity of power being ate up at a given time is measured in watts--that's the ability point. To degree how lots electrical energy you utilize you utilize you need to use kilowatt-hours (or watt-hours, yet its greater handy to apply the former). So--in case you utilize a million kilowatt-hour, meaning you have been ingesting power at an favourite. fee of 000 watts (one kilowatt) for a million hour. Now, it may be VERY united statesa. for a house to apply 5,000 kilowatt-hours in a month--that's an exceptionally severe discern. Yor top power utilization could be 5,000 watts. A image voltaic panel equipment with a optimal technique of 2000 watts isn't adequate to power maximum residences. you easily want a minimum of two times that--and so lots greater in case you like to bypass off the grid. besides the shown fact that it must be an excellent investment besides. you are able to use very practically all the means advert that woudlld maximize your mark downs.
Q:Can one benefit from solar panels?
Solar panels are very effective ways to collect, store, and use energy. However at this time they still are not incredibly cost effective. People scream and shout about being green, however being green needs to be practical. If an electric bill costs triple what you pay now just for being green that seems like crap to me. It kind of reminds me of organic food. (If labeled organic and 99 cent item costs 5 bucks.) The sad thing is if only solar panels were massed produced they could be a method for collection of electricity. However currently they are only used either for demonstration purposes or scientific use. Mankind way of thinking about energy needs to change before this can be seriously seen as a method of energy.
Q:How about solar panels?
I have a better idea . Why don't we pull our troops out of there and take the money that we spend to kill people and build a mass amount of solar cells and hand them out to our own people maybe give one of our hungry people a little food to go with it . You could even take a little of that money and put some kids through college . I can think of thousands of things to do with that cash . Why don't we ever take care of our own people first ?
Q:Cost of a solar panel?
You are probably better off buying solar cells and making your own solar panel. That is what I plan to do. Figure in the cost of batteries, an inverter, and maybe a charge controller. You will need to test the solar panels to make sure you have enough power to power up everything you have. If not, make additional solar panels, and connect them together. Nevertheless, I think it still might cost way over $200, but I think it is the cheapest way to go.
Q:What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.
Q:how to build solar panels?
There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak. So basically, you need to lay out the PV cells and wire them together to get the desired voltage and current, with some arrangement to allow the wires to extend outside without leaking. Then you enclose the panel around all four edges with aluminum channel and seal with silicone sealer. Lay it on thick and test thoroughly with water hoses to eliminate all leaks. As mentioned, it's easier and cheaper to buy them factory made. If you mean a heat collector for a solar house heating system or hot water system, that is just a matter of building a thin, flat aluminum box with a glass lid. For hot air, you just need to circulate the air through the box when the sun is shining. For water, you need to have some arrangement to pass the water through the compartment in thin walled metal tubing. You won't be surprised when I say it's cheaper to buy one factory made. Good luck.
Q:architecture and solar panels?????????????
They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.
Q:Charging batteries with a solar panel?
Batteries will not stop charging on their own. The will stop charging when the battery voltage equals the supply voltage. Solar panel open circuit voltage is typically around 20V. Batteries will just boil dry before reaching 20V. One rule of thumb, above 0W you need a controller for sure.
Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
