- Q: in a solar panel, i know that the electrons are knocked loose and used as energy, what happens to the protons?
- silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
- Q: Where can I find good instructions to build a cheap solar panel on my own?
- To build an effective but cheap solar panel, you need some expert advice. I recommend you get your hands on the comprehensive e-book and video instructions by Michael Harvey. His guide is very easy to follow and it will help you make a complete solar power system for less than $200. He also teaches how to make windmills. I hope this helps!
- Q: Can solar panels be installed on mining or extraction sites?
- Yes, solar panels can be installed on mining or extraction sites. They provide a sustainable and renewable source of energy, reduce carbon emissions, and can offset the energy demands of these operations. Additionally, solar panels can help reduce operating costs and dependence on fossil fuels. However, specific feasibility studies and considerations are necessary to assess the site's conditions, energy requirements, and potential environmental impacts.
- Q: So how does a solar panel work? Where does the energy get stored in? How much does one cost for a small 2 family home? How much money would we save on electricity?
- it all depends on how much electricity you use for heating/cooling and cooking.......if you just need lights, TVs etc then you could get away with about $5-8,000 US for a system depending on how far north you live.....to go completely off the grid is near $25,000 by the time batteries and inverters and all of that is figured in....
- Q: Most solar panels (the flat ones that go onto roofs of houses) reject electricity produced by the panels if they are too low in voltage. For example, on a cloudy day, although the panels may still get some sunlight to produce some electricity, it is rejected because its too low in voltage. So, does anyone have any ideas?
- apart from, the way image voltaic panels are under pressure jointly can impact the voltage output. If the panels are under pressure with the output of one connecting to the enter of the subsequent, or in sequence, the voltages of the panels upload up. case in point, in case you have 4 2 Volt panels under pressure in sequence, the finished voltage of the array could be 40 8 Volts. If the panels are under pressure so as that each and one and all their inputs and outputs are linked, or in parallel, those comparable 4 panels could have a entire voltage of 2 V, however the gadget could have 4 circumstances the present (Amps) of one panel.
- Q: Do solar panels work at night?
- No, solar panels do not work at night because they require sunlight to generate electricity.
- Q: Can solar panels be used for irrigation systems?
- Yes, solar panels can be used for irrigation systems. Solar panels can generate electricity which can power the pumps and other components of an irrigation system, reducing the reliance on traditional power sources and making it a more sustainable and cost-effective solution.
- Q: Why should I have a Generator if I have Solar Panels.....?
- Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.
- Q: Can solar panels be used in areas with frequent lightning storms?
- Yes, solar panels can be used in areas with frequent lightning storms. However, it is important to install proper lightning protection measures to ensure the safety of the solar panel system. This may include grounding the panels and using surge protectors or lightning arresters to divert the electrical charge from lightning strikes.
- Q: im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?
- your solar panel has to be a bit higher in voltage than your battery to achieve charging. I.E . if your battery is 3.6 volts, your solar array voltage should be like 5.v. to make the charging take place. always a bit higher than your battery,. wattage is not so important, you can charge a whole slew of batteries with a .5 watt charger, it just takes a while. higher wattage will make it charge faster, tho. v. x a. =w.
