Q: I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?: Ive been using the same solar panels for 5 years, have move a few times so they last a lot longer than the roofs weve had over us. I am teaching my kids how to build wind generators, because we keep having power failiures when the wind blows. and recently its got very windy. I charge banks of battery's and keep my office running from dc-ac converters.

Q: Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.: Be glad you didn't buy. The current products are dinosaurs, 50 year old over priced tech. Don't lose hope though. The thin film tech is just now starting production. It's not yet available to the general public ( production for the next year is already sold out), but will be in the near future as production capacity increases. It should drop prices to about /4 of the current price, and your recoup time will be about 7 years. Go ahead and research thin film solar, and be thankful you didn't buy a product the government has to pay you to buy.

Q: Can solar panels be used for powering remote monitoring systems?: Yes, solar panels can be used to power remote monitoring systems. Solar panels generate electricity from sunlight and can charge batteries or directly power devices. This renewable energy source is ideal for remote locations where access to the electrical grid is limited or unavailable. Solar panels can provide a reliable and sustainable power solution for remote monitoring systems, ensuring continuous operation without the need for frequent battery replacement or reliance on fossil fuels.

Q: Are there any fire risks associated with solar panels?: Yes, there are fire risks associated with solar panels, albeit they are extremely rare. These risks can occur due to factors such as faulty installation, damaged wiring, or issues with the electrical components. However, industry standards and regulations have significantly improved over time, ensuring safer installations. Additionally, regular maintenance and inspections can help mitigate these risks and ensure the safe operation of solar panel systems.

Q: Can solar panels be installed on flat surfaces?: Yes, solar panels can be installed on flat surfaces. While it is more common to install solar panels on angled surfaces or rooftops to optimize their exposure to sunlight, flat surfaces can also be used. In such cases, mounting systems or support structures are used to tilt the panels at an angle that maximizes their efficiency.

Q: I want to build solar panels for my house.Dose anyone try okorder is this really work?: Build okorder

Q: I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?: There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.

Q: Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen: Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!

Q: solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you: The idea is to hand assemble scrap solar cells that would otherwise be thrown out. At one point in time, very few people would want to do this so you could get the broken solar cells for free but now they sell them by the watt. It's still cheaper than a pre-fabricated solar panel but it's very labour intensive. Technically it's like wiring a bunch of batteries together, you measure the voltage and current a broken cell produces and decide whether or not to wire it in series or in parallel with other cells to get the performance characteristics that you want plus try to fit them onto some kind of structural panel in a fashion that uses the space efficiently. Since your handiwork is likely to be fragile, you'll probably have to put some plate glass on top to protect the cells from the elements, you can also improve performance by positioning fresnel lenses to increase the amount of light on active elements versus inactive areas of the panel.

Q: I would love to put in solar panels on my roof, but how hard would it be, and how expensive? Would I be able to do the work myself, or would I have to hire a pro?Also I live in Oregon, so much of the time it is overcast, so would it really be worth it?: Not a good idea. The reason why panels are that much more expensive than cells is that the panels themselves are not that cheap either. If you start with the cells, you'll need - mechanical protection (hail, ice, snow) - electrical protection (i.e. waterproofing - if water comes in contact with the cells and wires, you'll get electrolysis which will corrode your wires and contacts faster than you can say 'b*mmer') - that setup will need to withstand temperatures between -20 and +30 °C (only guessing, might be worse) - oh, and the side facing the sun must be transparent (as far as possible) Now as to connecting the stuff: no, it will be neither easy to connect it to the house power nor to the grid - which is why that step (at least) in all countries I know of must be done by a certified electrician. If you get it wrong and you're lucky, only _your_ inverter will explode. Regarding the power: these 4W per cell (or kW for your shed) is the peak value, i.e. with the sun shining orthogonally onto the cells on a clear day. Since this (for a fixed installation) will only be true (at most) for a few minutes on a few days each year, your overall yield will be significantly less, probably more like 4 kWh/day for each clear day for each kWpeak you install _IF_ the shed roof is oriented exactly south and inclined towards the sun's noon position at the spring/autumn equinox (i.e. inclination angle = your geographical latitude). How many clear days do you have in britain? Yes, I had a similar idea for myself - but for one thing, the registered companies I addressed apparently weren't really interested in that small fry, plus the cost of the system + setup would barely have been amortized after the expected lifetime, even taking into account the (german) governmental subsidies. If I had the money to spare, I'd rather invest in a communal solar park. Much better ROI, the large installations get much better prices (per kW) for the setup.
