- Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
- 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: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
- If you know where to look you get get solar panels for zero costs. For example, a lot of sign companies use solar panels. Contact your local sign company and tell them you will haul off all their broken solar panel for free. They are generally more than willing to let you do this.
- Q: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???
- Build okorder /
- Q: K i'm almost ready to give up! I've bought every kind of pv I can think of, and I can see this technology will not be affordable in my lifetime.I conserve all I can (so far as to handwashing my laundry etc) I'm not rich, but I'm saving for a solar pv with decent amperage. I love tinkering with things if I see the point.All the cells i've seen are very weak. What PV would you buy? (all I need is to power my computer from a deep cycle 2 volt battery connected to an inverter)God Bless You
- For okorder . If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter. I think you will see a significant drop in the price of panels in the next couple years, by the way.
- Q: What about sources for straight forward solar powered products? Excluding toys, garden frogs and outdoorpath lights I have found few useful items for the home. What I have found are solar panels for under $00 each, inverters, rechargeable indoor lights and a few camping/RV products that are interesting. It seems to me that these could help me start to wean the family off the power company. I can't afford to go cold turkey and cover my roof with solar panels and I don't think the HOA would allow me to even if I could. Is anyone using solar on a small scale?
- I okorder Hope this helps.
- Q: i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel
- [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
- Q: The battery is 9ah and the solar panel is 20w
- despite the statements to the contrary, using a solar panel to charge a battery is not rocket science. first lets look at you panel. panels normally have a spec for open circuit voltage (probably 20 volts for yours) operating power (4.4 volts at .4 amps is usual for 20 watt panel) and short circuit current (probably 2 amps in your case). if this panel is connected to a 2 volt battery, it will develop 20 watts of charge current in full sun. if this panel is connected to a 6 volt battery, it will work closer to the short circuit current or about .8 amps. doing the math this is a 7.2v x ,8= 3 watt charger for 6 volt batteries. while it is less efficient than when working at 2 volts, it will still work pretty good and no regulator is needed if you remember to disconnect the panel after 5 hours of full sun. if you want to walk away and have it run automatically, then you will need to find a 6 volt charge controller.
- Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
- First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
- Q: Can solar panels be installed on a hotel or hospitality establishment?
- Yes, solar panels can be installed on a hotel or hospitality establishment. In fact, many hotels and hospitality establishments are increasingly adopting solar energy to reduce their carbon footprint, lower energy costs, and showcase their commitment to sustainability. Solar panels can be installed on rooftops, parking lots, or even as shading structures, providing clean and renewable energy to power the establishment's operations.
- Q: i need to know wat the parts of a solar panel are.
- A solar panel is just a collection of solar cells all wired up in parallel and series to provide a useful voltage. Typical solar cells only provide half a volt, maybe less, so usually you put 2 of them together to get a 6v solar panel or 24 of them to get a 2v panel. Solar cells are made in various ways, the most popular are silicon solar cells which are made with a chunk of silicon with a P-N junction in the middle and contacts on either side. When a photon of light comes in, the energy of the photon is converted to electrical energy. Individually, photons contain a tiny amount of energy, but when you have a solar cell in the sunlight, billions and billions of photons hitting it constantly create a useful amount of electrical energy. Solar panels are incredibly simple!
