- Q:my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP
- If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
- Q:How do solar panels affect the property's green certification?
- Solar panels can positively impact a property's green certification by enhancing its sustainability and energy efficiency. The installation of solar panels reduces reliance on non-renewable energy sources, decreases carbon emissions, and promotes the use of clean energy. This aligns with the requirements of most green certification programs, which prioritize environmental responsibility and conservation. Therefore, incorporating solar panels can contribute significantly to a property's green certification and help demonstrate its commitment to sustainable practices.
- Q:I want to know that if I put solar panels in space if Pluto can recieve energy for iPods and television
- Just to clarify, while the Sun superficially will look like a bight star from Pluto with no discernible disk, staring at it would damage your eyes. It still packs some punch even at Pluto's distance, but as others have so eloquently stated, installing solar panels on Pluto would be a tall engineering order for very little return.
- Q:Can solar panels be installed on a hotel or hospitality establishment?
- Yes, solar panels can be installed on a hotel or hospitality establishment. In fact, many hotels and hospitality establishments are increasingly adopting solar energy systems to reduce their reliance on traditional energy sources and decrease their carbon footprint. Installing solar panels on these establishments can help generate clean and renewable energy, lower energy costs, and showcase their commitment to sustainability.
- Q:How do solar panels affect roof ventilation?
- Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat absorption and helping to keep the attic space cooler. This can decrease the need for excessive ventilation and potentially lead to energy savings. However, solar panels can also obstruct the airflow on the roof, limiting the natural ventilation and potentially causing heat buildup. Therefore, it is important to consider the design and placement of solar panels to ensure proper roof ventilation is maintained.
- Q:if so, would it be possible to make (or remake) an organism that could subsist off of sunlight and external heat like plants?
- No, there are organisms like that for instance coral, but in order for them to give us energy we would need to fuse are DNA with theirs
- Q:Can solar panels be used in areas with high levels of electromagnetic interference?
- Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, it is important to ensure proper installation and grounding of the solar panels to minimize any potential impact on their performance. Additionally, the use of appropriate shielding and surge protection devices can help mitigate the effects of electromagnetic interference on solar panel systems.
- Q:Can solar panels be used for street lighting?
- Yes, solar panels can be used for street lighting. Solar-powered street lights use photovoltaic panels to convert sunlight into electricity, which is then stored in batteries for use during the night. This renewable energy source helps to reduce electricity costs and carbon emissions associated with traditional street lighting systems.
- Q:How will i construct solar panel?
- For powering a something that works on DC, like a gate opener, Elaine is right, and in some cases only ONE bigger cell is sufficient due to battery storage; however if the appliance is 20v AC, then an inverter is needed also. MOST of Elaine's answer is good, but a few corrections are needed: Plywood - use EXTERIOR grade only, and even then it can warp; chipboard or waferboard is preferable as it does NOT warp, BUT is not available most places in 3/8, /2 nominal, (5/32) is usually the thinnest available, and it is heavier than plywood. DO NOT use particle board. Superglue - NO, it dries too fast to be useful, in most cases. Wires - For a single cell OK, but for larger panels the best wire is tabbing wire, (which is flat,) which is available from all commercial solar cell dealers. Be very careful soldering this to the cells, as unless you buy the expensive flexible cells, they are easily damaged; I suggest also getting flux pens with liquid flux. Diode - Necessary, but needs to be large enough to handle voltage and current. Usually 25v and 5-30 amps,, one per panel. Plexiglas - OK, but NOT as long lasting as glass; best glass is the special solar glass which is designed to pass almost all of the proper light frequencies, but IS expensive, and usually needs to be specially ordered since most glass stores do not stock it. Double panes work well with the outer pane glass and the inner plexiglas, (to protect the cell if glass broken,) IF where might get damage, such as 'ground' mounting. AND Frame kits are available for larger panels, but IF you make your own, a good table router is a great advantage. Inverter - IF used for 20v AC appliances you MUST have an inverter capable of handling the load, and the best ones are modified sine, or true sine, wave types, and even the best are less than 50% efficient. Note that they will last longer if NOT used at more than 2/3 capacity.
- Q:What is the payback period for solar panels?
- The payback period for solar panels refers to the time it takes for the savings from reduced energy bills to equal the initial investment in installing the solar panels. The payback period can vary depending on factors such as the cost of the panels, the amount of sunlight in the location, and the local electricity rates. On average, the payback period for solar panels is around 5 to 10 years, but it can be shorter or longer depending on these factors.
