- Q: My house is aligned exactly North-South, so I have no roof facing South. Is it worth installing solar panels? Are there any good options for dealing with this situation?
- The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.
- Q: I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.

- Q: Hi there. I live in Colorado, and we obviously get a ton of snow there. I im looking into a solar power system for my home, and I am wondering if the snow will accumulate on the panels, or if, because of the energy passing through, it will melt on contact? By the way we get about 20' of snow each year, and it comes on often. I will also be putting them on my roof. Thanks for your help.
- The energy from the sun is converted to electicity, so there's very little heat produced. I doubt the snow would melt. Try finding a way to scrape it off or have them rotate so you can let the snow fall off.
- Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
- It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
- Q: Can solar panels be used for powering public transportation?
- Yes, solar panels can be used for powering public transportation. Solar-powered buses and trains are already in use in various cities around the world. These panels capture sunlight and convert it into electricity, which can be used to power the vehicles' motors, lighting, and other systems. This renewable energy source helps reduce carbon emissions and dependence on fossil fuels in the transportation sector.
- Q: Can solar panels be used in areas with high levels of air pollution?
- Yes, solar panels can be used in areas with high levels of air pollution. Although air pollution can reduce the efficiency of solar panels by blocking sunlight, advancements in technology have made solar panels more resilient to such conditions. Moreover, regular cleaning and maintenance can help mitigate the impact of air pollution on solar panels.
- Q: I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q: i would like to hook up a power outlet to a solar panelmy light system is 500watts will run for 8 hours/day between noon to 8PM.So what is the most effective system do I need?
- You will need at least 500 W of solar panels (probably more to cope with cloudy days), and a DC to AC inverter. Since you're going to 8pm you *may* want a battery bank system too for those shorter winter days.
- Q: I really need to know about the good companies who are selling good quality home solar panels.I lives in Pakistan, solar panels sell here are cheap but they doesn't work for long time, mostly they are quot;made in chinaquot;.Consumption of units of our house written on our electricity bill is 300.My dad is seriously thinking of purchasing a solar energy system for house that long last and works efficiently.So plz help me out.

- Q: How do solar panels affect the roof's integrity?
- Solar panels can have a positive impact on a roof's integrity as they act as a protective layer, shielding the roof from various weather conditions. Additionally, solar panels can help extend the lifespan of a roof by reducing direct exposure to sunlight, preventing damage caused by UV rays. However, it is important to ensure proper installation by professionals to avoid any potential issues such as leaks or added weight that could compromise the roof's integrity.
