Q:I want to get solar panels but not spend 20,000!! I found out that you can get a panel to run only your AC unit, I also found something that will run my pool pump! Anyone own either of these? How did you do? Where did you go? How much was it, and was it hard to install?
Solar panels are very expensive and take many years to pay for themselves. You'd be better off contacting your congressmen to lift bans on Nuclear and other producers of electricity. That would lower the costs and save much more than the hassle of hooking up solar power and batteries etc.
Q:How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please)
Build okorder /
Q:My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
Q:I am wondering how to store energy from a solar panel
I have no idea what you are doing or what you think you are accomplishing. A 235 watt panel isn't much energy. You can certainly store it with a plain old lead acid battery.
Q:What would these solar panels power? For instance, my energy bill shows 2035kWh for last month. How much would this remove from that if it outputted full power? Thanks!
These panels are for small remote applications. Traffic signs, motion sensor lights, etc, where it would cost more to run an electrical line than it does to buy the panel.
Q:How do solar panels connect to the electrical grid?
Solar panels connect to the electrical grid through an inverter, which converts the direct current (DC) produced by the panels into alternating current (AC) that can be used by homes and businesses. The inverter is then connected to the electrical grid, allowing any excess electricity generated by the solar panels to be fed back into the grid and used by other consumers.
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.
You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.
Q:I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
Okay okorder /... That metal strip up top is negative, if you turn it around and look on the back you will see another metal strip there which would be positive. When it comes to wire, I use 24awg audio wire I got from radio shack, they only have solid wire at this gauge at my local radio shack but stranded is preferable. Solar cells are super fragile too so you're going to want to be extra careful. I then take a length of stripped wire and lay it over the silver tab, I hold it in place with some electrical tape at each end. Here is where experience comes into play, you can't use just any solder when making these connections. Well, you can but it takes a hell of a lot more time and effort to get it right. Make sure to use 96/4 silver-bearing solder. I'm not sure why but 60/40 solder does not adhere very well to the cell and usually the soldering iron has to stay on the cell for far too long which ends up discoloring it. If you need help on how to solder send me a message, you need to know how to properly tin the iron, since this is such a meticulous and unforgiving soldering job.
Q:How much electricity does a solar panel produce?
The amount of electricity a solar panel produces depends on several factors, including the size of the panel, its efficiency, the amount of sunlight it receives, and its location. On average, a standard residential solar panel can produce anywhere from 250 to 400 watts of electricity per hour under optimal conditions.
Q:i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 4 volts in good sun and had my meter set on Ma or milliamps and got .83 which i am asuming that is .83 of one amp now i took those and multiplied .83 times 4 volts to = 34.03 watts. Is this large enough to charge a car battery in a day? And doese it make a difference for amps on how fast it charges or watts. i also was looking around and found 30 watt panels but had higher amps. I am very interested in building solar panels but i realize i dont know what i need to do to make shur they are big enough. my panel is only 9inch by 0 inch. It seems weird that i am putting out 4 volts
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.
