- Q: How do solar panels perform in extreme temperatures?
- Solar panels perform best in moderate temperatures, typically between 25 to 35 degrees Celsius. However, extreme temperatures can affect their performance. In extremely hot temperatures, solar panels may experience a decrease in efficiency due to an increase in heat-induced resistance. On the other hand, in extremely cold temperatures, solar panels may experience a slight increase in efficiency, as lower temperatures can reduce resistance and improve conductivity. Nonetheless, most solar panels are designed to withstand a wide range of temperatures and can still generate electricity in extreme weather conditions.
- Q: What is the principle of solar panels work?
- Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
- Q: looking for a solar panel to charge my laptop on the road, macbook is 60 watt 6.v 3.5a, what should i be looking for in a solar panel?
- Well that's a good idea,,,here's what ya need..First you need an array that will overcome the drain effect created by the in use or sleeping laptop...that is best solved by averaging out the real use of the machine in terms of watt/minutes...If you check your transformer you'll see it has a capacity which you have cited however the true use of the computer is about 40-50 percent of that in watt/minutes..but only while your using it and when in the sleep mode the watt/minute value drops even more to about 5%.... So if your actual use consists of 2 hours of use per day at 50% and 2 hours at 5% percent the actual wattage draw is only averaged out at 34watts/minute. optimally your panel should supply all your power from its photovoltaic conversion ,but in the real world application the panel only recharges ,over a period of time, the used power. So if you had a 5 watt (@ 2vdc) panel working 480 minutes and used up 35 x2=700 and 9 x2=8 for a total of 78 watts you would have 5 x 480 = 7200 watts input and a parasitic load of 78 watts in the two hours...well within the recharge state required.. For a little safety I would permanently wire a cigarette lighter type plug to the end of the panel this will keep the polarity correct and serve as a quick disconnet means...Also add a fuse at .5 amp... a good place to get these are on the internet....some are very expensive some a very cheap --go for a middle of the roader...Have a good one from the E...
- Q: How do solar panels withstand hail or other weather conditions?
- Solar panels are designed to be durable and withstand various weather conditions, including hail. They are made with tempered glass that is highly resistant to impact, ensuring that hailstones won't damage the panels. Additionally, the panels undergo rigorous testing to ensure they can withstand extreme weather conditions, such as strong winds and heavy snow. The frame surrounding the panels also provides stability and protection.
- Q: 260 watt solar panels on an rv?
- It depends on the power you need. There should be a controller between the battery and the solar pv panels.
- Q: How much is the cost of solar panels including installation for my home so that I can have low monthly power bills.
- Home systems start at $30,000 and go up. There are federal income tax credits to help offset the cost, but you still have to pay up front, more than the average person can afford.
- Q: Can solar panels be installed on multi-story buildings?
- Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings are often ideal for solar panel installations as they have a larger surface area to accommodate more panels. Additionally, the height of the building can provide better exposure to sunlight throughout the day.
- Q: Dear Friends, I am very much worried about Global warming, So to contribute something for reducing Global Warming I have decided to use Solar Panels. Can anybody tell me what is the price of these Solar Panels and why people are not using them when they are environment friendly. What are the Pros and Cons of these Solar Panels?
- A 35 Watt Solar Panel cost between 400 and 500 depending on where you make the deal. I live full time in an RV and I get all my electric from the Sun. I am sold on solar but I move around to places, according to the season, where I will have full sun most of the time. I also have a small generator as a back up but rarely use it. The amount of direct sun and angle of the panels will determine how efficient they are. For some one living in an apartment with only a few hours of sun then solar would not be good for them.
- Q: Can solar panels be used to power a construction site?
- Yes, solar panels can be used to power a construction site. They can provide a sustainable and renewable source of energy, reducing the need for traditional fuel-based generators and minimizing carbon emissions. Solar panels can be installed on rooftops or on portable structures, providing electricity to power tools, lighting, and other equipment required on a construction site. Additionally, excess energy generated by solar panels can be stored in batteries for use during non-sunlight hours, ensuring continuous power supply.
- Q: i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.
- This site has some good info and links to more info about renewable and alternative energy. Hope it helps you. Good luck.
