Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?: No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)

Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /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.

Q: Can solar panels be used for powering a telecommunications tower?: Yes, solar panels can be used to power a telecommunications tower. Solar energy is a renewable and sustainable source of power that can efficiently generate electricity to meet the energy demands of a telecommunications tower. By harnessing the sun's energy through solar panels, the tower can operate off-grid and reduce its reliance on traditional power sources, making it more environmentally friendly and cost-effective in the long run.

Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.: I wouldn't worry about what the solar panel is going to do to the surrounding environment, I would worry about what the surounding environment is going to do to the solar panels.

Q: How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please): Build okorder /

Q: I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.: With that size panel, you should be able to recharge either AA battery, or two AA batteries in series. Yes, it would be a good idea to put a blocking diode in series with the panel - anything will do, like a N448. You will want to use NiCd batteries if possible, because they take a trickle charge of 50 mA much better than NiMH (which prefers pulse charging, a more complicated circuit). You can use NiMH if you must. Needless to say, don't try to charge non-rechargable batteries. Also realize that at this charge rate, it will take days, maybe even a week, to charge the batteries, if left out in full sun all day long.

Q: I am going to be building green in the next couple of years and i need an idea of how many solar panels i need in addition to a wind turbine to sufficiently handle a workshop, house, green house, etc. and what the approximate cost will be.: Photovoltaic solar panels are priced by the watt. Average price today is just under $4.00 per watt. More efficient panels take less space to produce the same amount of electricity. To design a system, you first must decide how much power you are looking to produce. then you look at the various products to find what fits your need. if you have a very compact space, you may pay more for more per watt for really efficient panels, but if you have a good amount of space you can get lower cost panels that take more space and cost less. With a wind turbine complimenting your system you will only need a modest battery storage bank. 5kw system could get you off grid entirely! 5,000 watts x $4.00 = $60,000. 3kw system with net metering mat cost about $2,000. Many homeowners (like me) build their systems piecemeal to keep costs manageable. Good Luck! P.S. - If you build it with the house, the price can be rolled into the mortgage. $60,000 would add +/- $300.00 a month to your payment, but you would have no Electric bill, a savings of $00-200 a month. Once it is paid for, you only have to pay maintenance costs.

Q: I was trying to look online for solar panels for my home to take some of the strain off of using oil and electricity but I find it very hard to understand exactly how they are used.Like one that I looked up is 00 watts.....is that like a light bulb watt? How many things can that power? Is it really cheaper in the long run because the panels are very expensive?If anyone has web sites that can explain this to me I would appreciate a link, or anyone to answer part of my question.: I had one on my homestead in CT. It grew to become right into a photograph voltaic warm water heater. It grew to become into hooked as much as my general warm water tank, so as that if it have been cloudy for a pair of days..i could nonetheless have warm water. in case you think of of all of the nice and comfortable water you employ, it grew to become right into a real mark downs. whilst i bought it, you purchased a $3000 tax credit from the government. that could be a protracted term investment , yet i could say mine paid for itself in 3 or 4 years. i could be careful presently..with oil being so costly, you going to have crooks and fly by utilizing nighttime businesses obtainable.make certain you examine out the corporation...very intently. And be taught , be taught, be taught...approximately how the structures paintings

Q: we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.: Give some green to go green.

Q: Can solar panels be installed on a pergola or shade structure?: Yes, solar panels can be installed on a pergola or shade structure. In fact, this is a popular option for homeowners who want to maximize their solar energy production while also providing additional shade and functionality to their outdoor space. The pergola or shade structure can serve as a sturdy and aesthetically pleasing platform to mount the solar panels, allowing for dual benefits of energy generation and outdoor comfort.
