- Q: Solar panel experiment ?wat are some experiments with solar panels that has not yet been proven? ideas
- Acciona of Spain is actively conducting research in all sorts of alternative energy. I understand they have an experimental solar farm someplace in the desert southwest of the U.S. that is made up of 283,000 panels. I don't know the size of the panels or anything else about the project other than that. 50 years ago it would have been the U.S. conducting leading research in solar energy-especially in the U.S. Southwest.
- Q: I have 2 solar panels one is 5 watts 2 volts .2 amps or -The other is 50 watts 2 volts 2.6 amps or-Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking them up to a 7 amp 00 watt charge controllerThe panels are rated 2 volt but the specs say they will produce more whennot connected to charge controllerPlease advise and should I even bother with the smaller panel ?
- The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.
- 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: Can solar panels be used for heating water?
- Yes, solar panels can be used for heating water. Solar water heating systems utilize the sun's energy to heat water for domestic or commercial use. These systems typically consist of solar collectors, which absorb sunlight and convert it into heat, and a storage tank to store the heated water.
- Q: Can solar panels be used in areas with high winds?
- Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panel installations are properly designed and anchored to withstand the wind speeds typical for the area. Additionally, selecting durable and wind-resistant panel models can help mitigate any potential damage caused by strong winds.
- 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: I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.

- Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- well i highly dout that solar panels ued for boats and rvs will work the same for your house, because your house requires more energy to run then a solar power can give.
- Q: Can solar panels be installed on a pole or ground mount?
- Yes, solar panels can be installed on both poles and ground mounts. Pole mounts are often used when there is limited space on the ground or when panels need to be elevated for better sunlight exposure. Ground mounts, on the other hand, are ideal for larger installations or when the ground is more suitable for anchoring. Both options offer flexibility in terms of placement and can effectively harness solar energy.
- Q: Can solar panels be installed on a boat or RV?
- Yes, solar panels can be installed on both boats and RVs. They provide a sustainable and efficient source of energy, allowing for off-grid power generation while traveling or moored. The panels can be mounted on the roof or other suitable areas to capture sunlight and convert it into electricity to power various onboard appliances and systems.
