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:I have a home in Manchester Tn and we have been slowly remodeling the home. It is about 200 sq ft of living space. Our normal electric bill is about 50 a month. We would like to add some solar panels to the home to help reduce the amount of the bill. How many panels do I need and what would be the cost? I am not trying to go completely of the grid but I would like to start somewhere and maybe over the years be able to add. What is your recommendation for a reasonable cost of under 2 to 3 k??: you need to read and ? your elect co they will help you with survey of your elect use and how to lower bill . for free also read about solar panels and how to use and install bg makes good panels but panels only small part of cost invertor and controler and batterys bigger cost the real expense is panel and controler for panels to to grid connection as per nec is very expensive more than 2 for most 00 or 200 amp service you would better to change to demand type warer heater and flouresent lights and upgrade isullation depending on how you heat house and your area heat pump etc but call your elect co for engergy survey

Q:Can solar panels be installed on airports or transportation hubs?: Yes, solar panels can be installed on airports or transportation hubs. In fact, many airports and transportation hubs around the world have already implemented solar panel systems to generate clean and renewable energy. These installations not only help reduce the carbon footprint of these facilities but also contribute to their energy self-sufficiency and cost savings.

Q:I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks: I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.

Q:Can solar panels be installed on golf courses?: Yes, solar panels can be installed on golf courses. In fact, many golf courses are adopting solar energy systems to reduce their carbon footprint and lower their energy costs. The large open spaces and ample sunlight available on golf courses make them ideal locations for installing solar panels. These panels can be placed on rooftops, parking structures, or even on the ground without interfering with the gameplay or aesthetics of the course.

Q:Can someone explain to me how solar panels can be used as modern architectural attributes? please help: They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.

Q:Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?: You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.

Q:can i put a solar panel on a projector. if nt wat is a low energy projector that i can watch movies and play games on: Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.

Q:Do solar panels require regular cleaning?: Yes, solar panels do require regular cleaning to maintain their efficiency. Dust, dirt, bird droppings, and other debris can accumulate on the surface of the panels, reducing their ability to generate electricity. Regular cleaning ensures optimal performance and maximizes energy output.

Q:Can solar panels be damaged by hail?: Yes, solar panels can be damaged by hail. Hailstones can cause cracks or breaks in the glass surface of solar panels, potentially reducing their efficiency or causing them to stop working altogether. However, the extent of damage largely depends on the size and intensity of the hailstorm, as well as the quality and durability of the solar panels.
