Q:Can solar panels be installed in areas with frequent power outages?
Yes, solar panels can be installed in areas with frequent power outages. In fact, solar panels can be a great solution to mitigate the impact of power outages as they generate electricity from sunlight, reducing reliance on the grid. Additionally, with the integration of energy storage systems, solar panels can store excess energy produced during the day and provide backup power during outages, ensuring a continuous power supply.
Q:I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?
But int the summer months you will have longer days than someone on the equator. Depending on your local power company, you may be able to back feed into the grid and draw back out the same amount a few months later.
Q:My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?

Q:Can solar panels be installed on concert venues or music festivals?
Yes, solar panels can be installed on concert venues or music festivals. In fact, many venues and festivals are increasingly adopting solar power as a sustainable and renewable energy source. Solar panels can be installed on roofs, canopies, or even on the ground surrounding the venue, providing clean energy to power the event and reduce its carbon footprint.
Q:I need to know how solar photovoltaic panels work. Anyone have a good explanation?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:Here's a little idea I though might help everyone out in Iraq a little: How about if the US mass produces solar panels that are small enough to carry (maybe one foot by three feet) that have a regular power outlet on them to the Iraqis? We could send convoys to the people waiting in line to buy gas and give each person one free solar panel. Why?. A lot of people are buying gas to run generators for air conditioning, not to fuel vehicles. 2. It would help reduce the gas lines if people only needed gas for cars instead of their generators too.3. It would help reduce the fighting over the power grid if people didn't need the grid for their own electrical power.My theory is, once every family in Iraq has enough of these panels that they don't even care about the power grid (during the daytime anyway) it would be much easier to fix the power grid. Maybe these solar panels could even connect to and add to the power grid.
In oil rich Iraq it would be counter productive to take such an initiative. There is already a huge shortage of solar panels. If you drive the price up more, which you're plan would do, It would just set back their growth in the U.S. and other developed oil poor places. This would hurt us a lot more than it would help them.
Q:I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
Solar panels have their own characteristics and generate current depending on the intensity of sunlight falling on them and not on the temperature. Direction of the panel also makes lots of difference. Nowadays very thin panels are available at very high cost. The more area a panel occupies it generates more current. The current generated by a panel cannot be readily used since the current and voltage varies with the load connected to it. So normally a regulator is used to have constant voltage and constant current to come from the panel. This charges the battery. You have to calculate the total/normal current from the charger and then find the AH of the battery. When you have calculated the AH of the panel/charger then you can divide the AH of the battery by the AH of the charger/panel and find out the time taken to fully charge the battery. You also have to remember that there is a de-rating factor to be taken into consideration in the battery.
Q:3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts
I have been using solar panels for over ten years never until recently bothered to use a charge controller, it depends really on how much power your batteries can hold how often they will be drained from use of the connected dc-ac inverters. While constant daylight charging at 8v 3.5a/hr is quite heavy it is not excessive, 2v lead acid battery chargers give a voltage output of appx 4.8v but the fluctuating output of a solar panel means you may well charge at 8v for some time but with occasional shade etc it will more likely average at 5v which I think is quite acceptable.
Q:Can it be used on a cellphone so u never have to worry about low battery?
A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.
Q:Can solar panels be used in areas with high levels of seismic vibrations?
Yes, solar panels can be used in areas with high levels of seismic vibrations. However, it is important to ensure that the solar panel installation is structurally sound and designed to withstand the vibrations caused by seismic activities. Additional measures such as reinforced mounting systems or flexible support structures may be needed to enhance the resilience of the solar panels in such areas.
