- Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q: what is one benifit in a solar panel?
- Solar panels can be used for main grid connection, remote power with batteries, remote solar lighting, on vehicles or boats. Solar panels have a life of up to 30 years. The energy used to make a solar panel is recovered and solar panels can even make an income. Green power can be sold back to the grid at premium prices in some places around the world.
- Q: Can solar panels be installed on residential complexes or apartment buildings?
- Yes, solar panels can be installed on residential complexes or apartment buildings. In fact, they are increasingly being installed on such structures to harness clean and renewable energy for multiple households. The installation process typically involves placing the panels on rooftops or in open spaces within the complex, allowing residents to benefit from reduced electricity costs and a more sustainable living environment.
- Q: Can solar panels be installed on windows or glass surfaces?
- Yes, solar panels can be installed on windows or glass surfaces. These solar panels are known as transparent or semi-transparent solar panels and are designed to allow light to pass through them while still generating electricity. They are commonly used in buildings where traditional solar panels may not be suitable or aesthetically pleasing.
- Q: Can solar panels be installed on a streetlight?
- Yes, solar panels can be installed on a streetlight. This allows the streetlight to be powered by solar energy, reducing reliance on the electrical grid and contributing to a more sustainable and cost-effective lighting solution.
- Q: How do solar panels affect the roof warranty?
- Solar panels can affect the roof warranty in some cases. The installation of solar panels usually requires drilling holes into the roof, which may void certain parts of the warranty. However, many reputable solar companies offer their own warranty and insurance to cover any potential damages caused during installation. It's important to review the terms of both the roof warranty and the solar panel warranty before proceeding with the installation to ensure that you understand any potential impacts on the roof warranty.
- Q: Are solar panels suitable for commercial use?
- Yes, solar panels are suitable for commercial use. They are a cost-effective and sustainable energy solution for businesses, providing long-term energy savings and reducing carbon emissions. Additionally, advancements in technology have made solar panels more efficient and affordable, making them a viable option for commercial establishments of all sizes.
- Q: How do solar panels generate electricity?
- Solar panels generate electricity through the photovoltaic effect, where sunlight is converted into electricity. The panels consist of multiple solar cells made of semiconductor materials, typically silicon. When sunlight hits the cells, it excites the electrons, causing them to flow and generate an electric current. This current is then captured and used to power various devices or stored in batteries for later use.
- Q: Just curious.
- Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
- 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.
