- Q: Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
- How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
- 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 solar panels be used to power a public transportation system?
- Yes, solar panels can be used to power a public transportation system. Solar energy can be harnessed through photovoltaic panels and converted into electricity to power electric buses, trams, or trains. This renewable energy source can significantly reduce carbon emissions and dependence on fossil fuels in public transportation, making it a more sustainable and environmentally friendly option.
- Q: Ok so i can have a problem i have two 5 watt 2 volt solar panels a 2 volt battery and a 400 watt ac 2 volt dc inverter i believe im only getting 5 watts from from my solar panels thats the equivalent of one is there any way i could get full voltage from my solar panels without theoretically burning my wallet.. please help
- I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
- Q: I have a solar energy panel that works in every room except mine. I have those severely bright, energy efficient bulbs and it doesn't work at all.What do I do? Is the bulbs really causing this? Why?
- It's giving off a good chunk of its energy as light in the range 800-00nm which the solar panel can efficiently harvest into electricity. As a lightbulb though, this energy is being wasted because you can't see light of those wavelengths!
- Q: Are solar panels affected by temperature?
- Yes, solar panels are affected by temperature. Higher temperatures can decrease the efficiency of solar panels, causing a decrease in their power output.
- Q: Was at home depot today and a Solar City sales man came up to me, offering me free solar panels. He said he could install them on my garage for free, free installation, free panels. Promised me it wouldn't cost me a dime. This is obviously appealing to someone like me who has a $200.00 monthly electrical bill. Now my question is this. Is this a scam? Are there ANY hidden fees or things I should be weary of?- I understand I may not save tons of money, but if I can save even something as low as $20 a month I would be happy. I live in a sunny area and they seem very interested in my garage roof. Any information would be super-helpful, thank you.
- Remember, if it sounds to good to be true, it usually is .
- Q: Can solar panels be installed on a building with historical significance?
- Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the preservation of the building's architectural integrity. Careful planning and design are necessary to ensure that the installation of solar panels does not compromise the historical value of the building.
- Q: What sort of maintenance is required for solar panels....?
- All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
- Q: Can solar panels be installed on a university or college campus?
- Yes, solar panels can be installed on a university or college campus. In fact, many educational institutions have already embraced renewable energy and have successfully installed solar panels on their campuses. These panels can help offset the electricity consumption of the campus, reduce carbon emissions, and provide a hands-on learning opportunity for students interested in sustainability and renewable energy.
