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.: There are lot of cheap solar panels today, Its all in the internet and most of them are made in China. Expand your knowledge and learn from a renowned solar company about the Cheap Solar Panels. Visit our site and contact us today!

Q: Can solar panels be used for powering a mining operation?: Yes, solar panels can be used to power a mining operation. Solar energy can be harnessed to generate electricity, which can then be used to power various equipment and machinery required for mining operations. The solar panels would need to be properly sized and installed to meet the energy demands of the mining operation, taking into account factors such as the required power capacity and the availability of sunlight in the location. Additionally, energy storage systems may be necessary to ensure a consistent power supply, especially during periods of low sunlight.

Q: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).: Homemade okorder /

Q: want to run 400 watt heater 8 hrs a day how many solar panels do i need and batteries: Get the rating from the manufacturer, they will give you the watts per m2 of their panels. divide 400 into the rating and will have the total area, then get the area of the panel that physically fits better the project and divide the total area into that of the panel selected, you will have how many panels you need. For the batteries is more complicated because of the available light hours of your location and what time of day are you going to use the heater, to be safe make a bank of batteries to store 600 watts to have a 50% stored power for emergency

Q: i've heard that solar panel batteries have to be replaced withen 5-0 years. how much do solar panel batteries cost? please include sources!: Solar panels produce but do not store electricity. Most decent solar panels should last for a few decades. They may be used to augment grid power with out batteries. Batteries that are used for storage in a battery backup system are the same ones that are used if the power were hydro, gen-set or grid. There are a variety of battery types with different shelf lives. Some are warrantied for 0 years that may last 20, but they cost more. Exactly how long they do last will depend on the environment they are kept. The capacity and number of batteries will effect the cost. The link below will give you a very good overview of pros and cons of the various types, along with links to some manufacturers.

Q: how would you build a solar panel: i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.

Q: What's your opinion on solar power? More specifically, having panels installed on your roof to reduce your electric bill. I'm having a consultation tomorrow to get more details. I live in the SW, so it's always crazy sunny here. I don't know what the cost will be yet. Is it something you'd consider if the situation was right? If not, why?: You dont say where you live? you need to consider average sunshine hours. There are some sites on the net that will work out for you what percentage of nameplate capacity you could expect to receive for different areas. Usually the capital cost wont be paid off for at least ten years, so money wise you would do much better by investing the cash. I once asked a guy (climate warmer) whether his solar panels had paid off or would do in the future, his answer was no but it was the right thing to do morally.

Q: Can solar panels be installed on schools or educational institutions?: Yes, solar panels can be installed on schools or educational institutions. In fact, many schools and educational institutions have already embraced solar energy as a sustainable and cost-effective solution. Installing solar panels not only helps reduce carbon emissions but also provides educational opportunities for students to learn about renewable energy and sustainability. Additionally, schools can benefit from reduced energy costs and potentially generate revenue by selling excess energy back to the grid.

Q: Can anyone give me some info on how to figure how many panels needed for a 0 volt 2 amp pool motor. Thanks/ Run 5 hours a day: You okorder /

Q: I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man: Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
