- Q: I know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.
- If you are at a location/time where the panel will put out less power, you can adjust the battery size accordingly. And running a battery to empty is very bad for it's service life, so it's better to go a bit bigger.
- Q: Can solar panels be used in remote areas?
- Yes, solar panels can be used in remote areas. They are a popular and viable solution for generating electricity in locations that are not connected to the traditional power grid. Solar panels can be set up in remote areas to harness energy from the sun and provide electricity for various purposes, such as lighting, powering small appliances, or even charging batteries. Their ability to operate independently without the need for extensive infrastructure makes them an ideal choice for remote areas where access to electricity is limited or non-existent.
- Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks

- Q: Can solar panels be used for powering water treatment plants?
- Yes, solar panels can be used for powering water treatment plants. Solar energy can be harnessed and converted into electricity to operate the various processes involved in water treatment, such as filtration, disinfection, and pumping. This renewable energy source can help reduce reliance on fossil fuels, lower operational costs, and contribute to a more sustainable and environmentally-friendly water treatment process.
- 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 have an active solar heater on my roof. During the winter it comes in handy and heats the house, though we still need to use a gas heater to get the temperature up to a comfortable level.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- If the panels are the same, there is no problem in putting them in series. If you examine the panels, they will be made up of about 36 identical cells in series. Ok, now you have 72 cells in series, fine if they are the same. You need (at a minimum) a diode in the line so that when it is dark, the panels do not draw current out the batteries (it wont be much but you might as well block it). You say the panels are rated 5 amps? Those are pretty good sized panels! Unless you have a charging regulator, I guarantee that they Will overcharge the batteries (unless the batteries are huge, like the size of a refrigerator). Did you maybe mean 5 watts? About a foot square? If so, the output is about 300mA (0.3 amps) which will not overcharge a battery as long as it is at least as large as a garden tractor battery. At a 300mA charge rate, it will take a longgg time to recharge.
- Q: Can solar panels be used for powering outdoor recreational vehicles?
- Yes, solar panels can be used for powering outdoor recreational vehicles such as RVs, campers, and boats. They provide a convenient and eco-friendly way to generate electricity for various appliances and systems in these vehicles, including lighting, refrigeration, heating, and charging electronic devices. Solar panels can harness the sun's energy to charge batteries, which can then be used to power the vehicle's electrical needs, making it a sustainable and cost-effective option for outdoor enthusiasts.
- Q: What is the difference between on-grid and off-grid solar systems?
- On-grid solar systems are connected to the local electricity grid, allowing excess electricity to be fed back into the grid and potentially earn credits or payments. Off-grid solar systems, on the other hand, are not connected to the grid and rely on energy storage solutions, such as batteries, to provide electricity when solar production is low or during nighttime.
- Q: I can't figure out how to charge a Ni Cd (BD 8V Firestorm) battery directly with a solar panel so I've come up with an alternative which might or might not work. I thought I would connect an inverter (I found a nice 400W for $30) to my trucks battery and plug the BD Firestorm battery charger into the inverter. Then I was thinking I could use a 5W solar panel to trickle charge the truck battery and keep it connected after the Ni Cd is charged to ensure the truck battery is topped off. The truck would not be running during this process. Will this solution work? Is there a better solution?
- Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
- Q: I'm very interested in how solar panels work. I understand the bigger picture of how it can be used for solar heating or as a generator, but I'm lost at the smaller details. Things like: - Could my computer work on solar? It has a 900 watt power supply (this is excluding monitor/speakers) - if a panel is for example, a 60 watt panel, does this mean it will pump 60 watts a second into a battery? - Does solar heating make the water electrified?
