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:Can solar panels be used in areas with limited sunlight?
Yes, solar panels can still be used in areas with limited sunlight. While solar panels are most effective in areas with abundant sunlight, advancements in technology have made it possible to generate some amount of electricity even in areas with limited sunlight. Additionally, solar panels can still be viable in these areas if combined with energy storage solutions or connected to the grid, allowing for a more reliable and consistent electricity supply.
Q:Can solar panels be installed on waste treatment plants?
Yes, solar panels can be installed on waste treatment plants. In fact, waste treatment plants provide ample space and suitable infrastructure for the installation of solar panels. This can help offset the electricity consumption of the plant and reduce its carbon footprint, making it a sustainable and environmentally friendly option. Additionally, solar panels can contribute to cost savings by generating clean energy on-site.
Q:i need to know wat the parts of a solar panel are.
For a photo electric system you need 3 basic things. Photo voltaic Solar panels the quantity determined by you need and a charge controller for the cells they are rated by current. Batteries the quantity determined by your needs. Last an inverter to convert 2 volts DC to 20-220 AC. The size shown in watts is determined by you needs. If you plan to use it all the time you will have to have piece of equipment usually part of the inverter to sync the inverter up with the public utility and any power you don't use gets sold to the power supplier. That our a manual switch which will not allow you to sell unused power to the power company. If you are thinking about this do your home work and if possible contact it out. This is not a good first time DIY especially since you are asking this question. No offense. Otherwise you will need to do some reading and studying. But no matter what there are parts that an electrician will have to do by law and you may need a permit depending on where you live.
Q:It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q:i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.
I'm sure that you might discover everything concerning solar power at www.okorder .
Q:Can solar panels be used in areas with high levels of noise pollution?
Yes, solar panels can be used in areas with high levels of noise pollution. Noise pollution does not affect the functionality or performance of solar panels. However, it is important to note that noise pollution does not directly impact the efficiency or effectiveness of solar energy generation from the panels.
Q:What is the difference b/w them which one is better .
how much does these pannels way and which are the most efficient?
Q:I would like to know how do you build a solar panel?
i think the evil Genius book has how to build home made solar cells.
Q:Do LED lamps ever go bad?What's the life expectancy of solar panels?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
