Q:What are the benefits of using solar panels?: There are several benefits to using solar panels. Firstly, solar energy is a renewable source of energy, meaning it will never run out. It also produces clean energy, which reduces greenhouse gas emissions and helps combat climate change. Solar panels can help homeowners and businesses save money on their electricity bills by generating their own energy. Additionally, solar panels require minimal maintenance and have a long lifespan, making them a cost-effective investment in the long run. Finally, using solar panels can also contribute to energy independence, as it reduces reliance on traditional fossil fuels and centralized power grids.

Q:i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.: Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?

Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port, can i just tie the wires together and run into the controller?? Will damage anything...Thanks guys: You should specify the controller ratings first. Otherwise it is not possible to answer your question.

Q:I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!: In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.

Q:Can solar panels be installed on a shipping container?: Yes, solar panels can be installed on a shipping container. In fact, shipping containers offer a suitable platform for solar panel installation due to their large surface area and structural stability. This allows for efficient utilization of space and easy integration of solar panels into various applications, such as off-grid power systems or mobile energy solutions.

Q:How do solar panels affect the roof's structural integrity?: Solar panels do not significantly affect the roof's structural integrity when properly installed. The panels are mounted on a rack that evenly distributes the weight, and professional installers ensure that the roof can handle the additional load. In fact, solar panels can even provide some protection to the roof by shielding it from the elements.

Q:Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts: The most energy effiecient PV cell in Australia at the moment is from First Solar they generate the most electricity compared to all units in Australia by an additional 6%. Not much but everything counts these days, especially with prices increasing over the next thress years (even without the CPRS) projections are (by IPART, who are the regulators that sets the electricity prices) rises by 46% (thats by Country Energy) and with the CPRS it was going to reach a 64% increase. The First Solar PV cells will give you a return on investment of around 2.75 years and generate electricity for 25 years (after 20 years they still generate Approx. 85% efficiency - best in market, I know I have been researching them for ages, and these are the ones I am installing !!!. Hope this helps. You need to choose a .5kW system, this will generate Approx $380pa

Q:Can solar panels be installed on a historic building?: Yes, solar panels can be installed on a historic building with careful planning and consideration. It is important to ensure that the installation does not compromise the architectural integrity or aesthetic value of the building. Special mounting systems and design techniques can be used to minimize any visual impact. Additionally, local regulations and preservation guidelines may need to be followed.

Q:a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.: It's not a matter of Federal money or Federal programs or attitudes of the government that keeps your grand plan for generating large amounts of electrical power using solar panel systems and distributing it country wide with fiber optics from becoming a reality. It's technology. Whatever optimistic speculations you may have heard or read, large scale, dependable generation of electrical power at steady high levels from solar cells is nowhere near a reality. Some of the big culprits are the variable atmosphere of the earth and the inefficiency of practical and economic solar cells. The conversion does not depend on the warmth of the states where generation might take place but on constant direct sunlight, unobscured by clouds in the atmosphere for most of every day, and on high efficiency solar cells. No states can depend on clear skies 365 days of the year and there's the little matter of night time, when nothing would be generated. Also, the electricity generated by solar panels cannot be carried by fiber optics since they carry electromagnetic energy (light), not electricity. What may be possible sometime in the not-too-distant future is the use of solar panels to supplement, not replace, conventional power generating systems on a local basis. It would not be required that they provide constant high levels of power every day, but only that they provide power when conditions were right, in order to perform the valuable role of cutting down on the use of fossil fuels in conventional generating systems. (The direct current generated by solar panels would have to be converted to alternating current or stored in batteries to accommodate our present methods and equipment for using electric power.) As soon as this becomes technically and economically feasible, we will not have to wait long to hear about it from the energy corporations and politicians.

Q:Can solar panels be installed on a convention center or event venue?: Yes, solar panels can be installed on a convention center or event venue. In fact, many convention centers and event venues have already embraced solar energy as a sustainable and cost-effective solution. The large roof spaces available in these facilities are ideal for installing solar panels, which can generate clean and renewable electricity to power the venue's operations and reduce its carbon footprint. Additionally, the visibility of solar panels on such prominent buildings can serve as a powerful symbol of commitment to sustainability and inspire others to adopt renewable energy.
