- Q: they are pretty expensive. So does it save you money on electricity in the long run? How easy is it to connect solar panels to your house?
- yes. Its pretty simple connection. It does save money on electricity.
- Q: Please, I want a good definition. :DD
- The previous answer stating that a solar panel is a method of collecting, and converting sunlight into electricity is correct, however once sunlight has been converted into electricity, it has to have a way to be stored, so that it can be used. This is accomplished by the use of storage batteries. It is stored in a DC or Direct Current form, and may then be converted to AC (alternating current) through the use of an inverter.
- Q: what is needed beside the panels and do you need an electrician to hook it up
- most times yes.
- 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
- leave the car in the sun for a few hours to see if it charges. if not, the panel is defective. get it replaced b4 the science fair
- Q: Can it be used on a cellphone so u never have to worry about low battery?
- Solar panels (arrays of photvoltaic cells) use renewable energy from the sun, and are a clean and environmentally sound means of collecting solar energy. Solar panels are a great way to generate electricity on a small scale. Solar panels are commonly named solar cells or photovoltaic cells. Photovoltaic means literally light electricity.” Solar cells or PV cells rely on the photovoltaic effect to absorb the energy of the sun and cause current to flow between two oppositely charged layers. Solar panel installation is a cost effective part of the green movement for saving energy. There are different types of solar panels available, including Monocrystalline Panels, Polycrystalline Panel, Cast Polycrystalline Panels, String Ribbon Silicone Panels and Thin Film Panels.

- Q: What is the warranty on solar panels?
- The warranty on solar panels can vary depending on the manufacturer and the specific product, but it typically ranges from 10 to 25 years.
- Q: 3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts
- It is cheaper to have a solar regulator to extend the battery lifespan. A lead acid battery can vent hydrogen if charged too much and run out of electrolytes. The battery would cost more than a $30 5 amp solar regulator.
- Q: Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?
- The solar panels run the fan to remove hot air from the car. They do about the same amount of cooling that cracking the windows and using a heatshield over the windshield--that is they keep the interior of the car about the same as the exterior without draining the 2V battery. One problem I have with the solar panels is that they come with a moonroof. The other problem I have with them is that to get them you have to give up the additional safety features because Toyota won't put both the high tech safety features and the solar panels on the same car. So is it a good design? Well, nothing with a sun/moonroof is a good design IMHO, but that's the power of advertising for you. In that it runs a fan without draining the 2V battery, yes that part's good. Having to give up the high tech safety features to get it makes it a non-starter for me (and I live where it gets plenty hot so I could really use the fan).
- Q: I have a solar panel that puts out 00v, .5 amps in full sun. Before I thought it would charge a 2v battery without a solar charger but then I talked to someone and they said that it was wasting a lot of power and could potentially hurt the battery. A second part to this question is what happens if I put it on a 72v battery without a controller. Thanks!
- yes not good.. why would put 00volts to a 2 volt battery? the best you can hope for is to destoy the battery 3.6v max do not excide max amp on battery
- Q: How do solar panels affect roof weight load?
- Solar panels can increase the weight load on a roof, as they require mounting brackets and additional equipment to be installed. However, modern solar panels are designed to be lightweight and are typically not heavy enough to cause any significant structural damage to the roof. It is important to consult with a professional to assess the roof's load-bearing capacity before installing solar panels.
