A: Yes, we can do that.
- Q: I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
- Wrong forum
- Q: What do I need to use this as a battery charger
- I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
- Q: what is one benifit in a solar panel?
- Solar panels enable use of sunlight for energy. Sunlight is a renewable resource, which means it won't run out, unlike coal and uranium (nuclear energy) and so forth. So there you go! It secures electricity for us for as long as the sun is there... which will be billions of years
- Q: Would like to know if the DIY Solar panel systems can be as efficient as a commercial grade panel.
- On my website you can read my story of how my dad made solar panels at home and now he pays nothing to the electric company.
- Q: I have a solar panel i got for free and I don't know what to do with it. Its kinda big at about 20x 0and it puts our 2 VOC / .23 ISC. I don't know of anything that I could use it for. Its too big to say charge a phone or ipod....any suggestions??
- Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
- Q: How do solar panels affect the resale value of a home?
- Solar panels can have a positive impact on the resale value of a home. Studies have shown that properties with solar panels tend to sell faster and at a higher price compared to homes without them. Potential buyers view solar panels as a valuable and eco-friendly feature, leading to increased buyer interest and willingness to pay a premium for a home equipped with solar power.
- Q: Can solar panels be installed on a warehouse or distribution center?
- Yes, solar panels can be installed on a warehouse or distribution center. In fact, these large, flat-roofed buildings are ideal for solar panel installations because they offer ample space and can generate a significant amount of renewable energy. Installing solar panels on warehouses or distribution centers can help reduce electricity costs, decrease carbon emissions, and contribute to a more sustainable energy system.
- Q: Can solar panels be installed in urban areas?
- Yes, solar panels can be installed in urban areas. In fact, urban areas provide ample opportunities for solar panel installations on rooftops, parking lots, and other available spaces. With advancements in technology and design, urban solar installations have become more efficient and aesthetically pleasing, contributing to the overall sustainability and energy independence of cities.
- Q: Can solar panels be installed on community centers or libraries?
- Yes, solar panels can be installed on community centers or libraries. In fact, community centers and libraries are often ideal locations for solar panel installations due to their large rooftops and high energy consumption. Installing solar panels on these buildings can help reduce electricity costs, promote renewable energy use, and contribute to a more sustainable and environmentally friendly community.
- 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.
- This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
