- Q: Can solar panels be used in combination with other renewable energy sources?
- Yes, solar panels can be effectively used in combination with other renewable energy sources such as wind turbines, hydroelectric power, or geothermal energy. This combination, known as hybrid renewable energy systems, allows for increased reliability, better utilization of resources, and a more stable power supply.
- Q: Im doing a project and i have to persuade some one that solar pannels are great... help ?
- Solar panels saves energy (electricity) because the power comes straight from the sun and stuff
- Q: Any recommendations for companies? Any things to look out for?
- Yes, solar panels are a great way to save on electricity costs for your home. 4 things I can tell you to look out for are: Make sure you can fit enough solar panels on your house to make a decent saving. If you don't have the roof space then you can't put up enough panels and you might as well not bother. For a medium sized home, I would say that you should go no smaller than 2.2kW in solar panels. If you can fit more then go for it. Make sure that the inverter that is used is big enough. It has to deal with the watts from the solar panels back to the power board to convert it as useable energy. If you have a rebate system where you live then make sure you use it. Where I am we have carbon credits that the government will give you that you use to offset the cost of purchasing solar. Don't fall for gimmicks where a company will promise you that you won't pay electricity every again. In order for that to happen you need to be putting more electricity back in the grid as you are currently using so you either need a huge amount of solar panels or you really need to cut back on what you are currently using.
- Q: How about using Solar Panals to provide the electrical power to separate the H2 from the O? H2 would be fed into the engines carburator like a gas/air mixture ratio, but H2/air mixture ratio instead. How would you control the exact measurements?
- Currently solar panels are rated at about 5 percent efficiency. That means that about 85 percent of the solar energy that is falling on it, is wasted. Electrolysis is also about 67 percent efficient. So the TOTAL amount of solar energy you would have converted into hydrogen is 67 percent of 5 percent. Using my calculator that comes out to: about 0 percent total efficiency. About 90 percent of your solar energy gets wasted in the process. A better alternative to solar panels would be solar powered sterling generators. Sterling engines are EXTERNAL COMBUSTION engines, like the old fashioned steam engine, and can be run off any heat source - including the sun. Heat from the sun is focused using parabolic mirrors, and the efficiency of a sterling engine / generator combination is rated at about 30 percent. Your TOTAL efficiency - both solar sterling and electrolysis combined - would be around 20 percent. If you are dead set on using hydrogen? Even though there are better alternatives? Such as alcohol? Then I would suggest storing it in titanium dioxide pellets. This way you can store the hydrogen, without it being in danger of exploding. You can ALSO ram a hydrogen container like this into a solid brick wall. Once again? Without fear of an explosion. Numerous studies have been conducted on this. As for controlling the exact measurements? Nothing in the air-fuel ratio of a car - - or the timing - which you are also going to have to change - needs to be exact. A good enough approximation will do. As for how you get your measurements? You need to compare the density of gasoline vapor with hydrogen gas. A comparison of the molecular weight of gasoline - - as compared to the molecular weight of hydrogen - should get you started in the right direction for this.
- Q: How do solar panels affect roof maintenance?
- Solar panels can have both positive and negative effects on roof maintenance. On one hand, solar panels provide an additional layer of protection to the roof, shielding it from elements like rain, snow, and UV rays, which can extend its lifespan. On the other hand, regular maintenance of the solar panels themselves, such as cleaning and inspection, may require occasional removal or adjustments, which could potentially impact the roof. Overall, proper installation and regular maintenance of both the solar panels and the roof are crucial to ensure their optimal performance and longevity.
- Q: Hi everyone, I am a novice in solar energy system. I want to know if I am on the right track. Recently I bought a 30 W solar panel, 5 Amp controller, and a 22 Ah battery, how many watts and what kind of INVERTER do I need? I did an research some said 50 W and some said 300 W. And am I right on the 5 amp controller and 22 Ah battery to provide larger output of electric, or the higher the # the greater output for 30 W solar panel?Really appreciate for anyone who help!!!
- must be one of the place who's place have sun
- Q: All I ever heard is how easy it is to get solar panels for a persons home. I live in Arkansas and to do my house it would cost 25000 that I dont have and No state incentives. So where do I go and get these free solar panels? Thanks for the help

- Q: okay so i want to know if solar panels shine. ------(MY Q'S ABOUT BLINDNESS DOESN'T MEAN PERMANENT OMG I CAN'T SEE! BLIND BUT THAT WE JUST CANquot;T SEE AT THE MOMENT BECAUSE OF THE LIGHT.)------------------------------like if/when they face the sun is there a glare to the people around?-if there is would the person have to look directly at it? -Could it reflect off of other objects and cause temporary blindness or just shine light in person's eyes?-if there were windows and mirrors near the solar panel would it affect a person's sight?-and if it did for how long would it hurt or take affect?-and is this physics? like-solar panels and how they work is that physics or some other category?
- Solar panels reflect less sun than a piece of window glass, and people aren't harmed by the sun's reflection off windows. Also, solar panels tend to be tilted more or less directly toward the sun, so the light that they reflect is back at the sun, not down into the street or yard where people are. Those huge power tower concentrating solar thermal plants have a brilliant light reflected off the boiler. But those are put out in the desert, away from people.
- Q: I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
- Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
