Q: Can solar panels be used for powering a manufacturing facility?: Yes, solar panels can be used to power a manufacturing facility. By harnessing the energy from the sun, solar panels can generate electricity that can be used to run various operations in a manufacturing facility, such as powering machinery, lighting, and other equipment. This can help reduce reliance on conventional electricity sources, lower operating costs, and contribute to a more sustainable and environmentally friendly business model.

Q: Can solar panels be leased or financed?: Yes, solar panels can be leased or financed. Many companies offer leasing options where homeowners can rent solar panels for a monthly fee. Additionally, there are various financing options available, including loans and power purchase agreements, which allow homeowners to pay off the cost of solar panels over time.

Q: Can you please tell me how much a solar panel costs?Please back up your info with a website.: If okorder /.. Low-cost crystalline panel manufacturers such as Suntech are believed to have costs in the $.50/watt range today - making it $300 for a 200-watt panel. That doesn't mean that one can buy a panel for that price, of course. If you mean a DIY panel from purchased solar cells, the cost would be closer to $360 for an equivalent-powered panel, not counting the price of the frame, and the labor. A homebuilt panel would not stand up to decades of weather unless one spent even more on the frame. And since such a panel would not have safety certification, it could not legally be connected to the grid in most places. If you meant a water heating panel, please update or post another question - I'm sure people will chime in.

Q: Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace: Homemade okorder /

Q: Can solar panels be installed on a library or educational institution?: Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions are increasingly adopting solar energy systems to reduce their carbon footprint, lower energy costs, and promote renewable energy education. Installing solar panels on rooftops or open spaces of these buildings can provide clean and sustainable electricity, benefiting both the institution and the environment.

Q: Any recommendations for companies? Any things to look out for?: There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Q: I am in the market for buying a home. There is one for salke that actually has solar panels on top. How are they used? Do you need to pay for gas and electric still. Does it really light up the house and keep it warm. WHat about the AC keeping hte house cool in the summer does it work for that too? Please explain in solar for dummy terms. I haveno clue about solar panels other thatn the fact that it needs sunlight to run.: No standard home can operate on solar panels alone unless there is about an acre or more of them. Plus, they require lots of batteries and complicated switching devices. And, they are very expensive, so rarely pay back their up front cost. Right now, more of a gimmick than a practical solution to power needs in the home. The house you're looking at may use it to power emergency lighting in case the grid went down. Or maybe a small fan to exhaust heat out of the attic. Who knows. Just have to ask.

Q: My family and I are looking into solar panels for our home. But I'm unsure how it would be priced. This month our home used ,623 kwh. The solar panel company said we should expect $6-$9 per watt used. What would that put as at?: As the day progresses, solar panels start at near 0% efficiency, then to 00% at high noon, then drops off to 0% in the late afternoon. So you have to ask if the ,500 watt system is the peak output capacity or the AVERAGE output where the average would be near 70% or less of the peak over the day. Just do a LOT of research and number crunching. I'm waiting until it is cheap enough to by the whole system. A warranty is no good if the company goes out of business.

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.: If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.

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!
