- Q: I have noticed how solar panels cause a glare. Since I am not around solar panels all the time I relate it to when the sun reflects off another car and right into my eyes. So I always wonder if solar panels effect birds and/or animals due to the glare. If I am wrong and solar panels aren't this bad please tell me.
- No, they don't solar panels are harm less to the enviroment. They take in light energy, nothing else. So you don't have to worry about injury!
- Q: Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.
- You can use mirrors to concentrate sunlight and boil water, but I don't know if that is cheaper. You'd need motors to keep the sunlight focused on the boiler. Or you could build a solar water heater. It doesn't generate electricity but it conserves the power an electric water heater would use.
- 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.
- How many batteries you will need depends on what you are planning to do with them which you did not mention? Sunforce makes a 30 amp charge controller part no. 60033
- Q: How do solar panels affect the local job market?
- Solar panels can have a positive impact on the local job market by creating new employment opportunities. The installation, maintenance, and manufacturing of solar panels require skilled and unskilled workers, thus stimulating job growth in the renewable energy sector. Additionally, the shift towards solar energy can lead to the creation of new businesses and industries, further contributing to job creation and economic development in the local community.
- Q: Can solar panels be used for powering remote monitoring systems?
- Yes, solar panels can be effectively used for powering remote monitoring systems. Due to their ability to generate electricity from sunlight, solar panels provide a reliable and sustainable power source for remote locations where access to grid electricity may be limited or non-existent. By harnessing solar energy, these panels can provide continuous power to remote monitoring systems, enabling them to function and transmit data without the need for traditional electricity sources.
- Q: How much electricity can a solar panel produce?
- The amount of electricity a solar panel can produce depends on several factors, such as its size, efficiency, and the amount of sunlight it receives. On average, a standard solar panel can generate anywhere from 250 to 400 watts of electricity per hour. However, larger and more efficient panels, combined with optimal sunlight conditions, can potentially produce even more electricity.
- Q: will at least consider them for their home electricity? I've seen several articles that new technologies are now being used, but it doesn't seem to be promoted to residential apps. I've even seen that the solar technology will be used in paints in the near future.
- Solar panels are cost effective if they are used over their payback period. The problem is that the down payment is expensive, and the payback period is maybe 0-20 years, so very few people actually expect to own their homes for 0-20 years. It also only really makes sense in areas that buy back electricity generated during the day when you're not using it. In Germany and other european countries, power companies are required to buy back electricity at a higher price than they sell it for--this reduces the payback period and is a great incentive for solar panels. For this reason, they are much more popular over there. Given a little time for the price to fall and given some change in energy policy, solar panels will become more cost effective in the future. Depends on who gets elected, though. There is a solution to the payback period problem, though. Rather than homeowners taking on the long payback period in homes they may not own long enough, some companies are buying panels and leasing them to homeowners. In exchange, homeowners get reduced electric bills, that pay off the lease payments, plus a little extra. I think this is the way to go. check out the link below.
- Q: What's the best deal going on companies leasing out Solar Panels in California?

- Q: I am interested in solar energy, but am not sure how eficiant it would be in the northwest? Any comments would be apriciated.
- If you have southern exposure . Go for it.
- 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?
- Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
