Q:hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.: wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .

Q:Can solar panels be installed on mining or extraction sites?: Yes, solar panels can be installed on mining or extraction sites. In fact, installing solar panels on such sites can provide numerous benefits. They can help reduce the reliance on fossil fuels, lower energy costs, and decrease greenhouse gas emissions associated with the mining or extraction operations. Additionally, solar panels can provide a sustainable and renewable energy source, contributing to the overall environmental sustainability of these sites.

Q:Currently being sold today! I know SunPower corp. commercial panels are about 20%.: Thats pretty much it for commercially available panels. The only ones more efficient are the one's they put on the Mars landers. They are triple layer panels that catch different spectrum's of light, much more efficient. Millions of dollars more.

Q:Please tell me what they are made of and how the materials help the solar cell produce electricity. Im doing a science projects so i need help on knowing all this info. Its a debate, so i need correct information please.I will please need more information about the bad things about solar energy and solar panels. Please say what solar panels do to create pollution or do anything that is not friendly to the environment. If you want just give me a website. Thank you: A okorder /, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.

Q:I have heard you can make your own solar panels.... But How?Where do you start? Is it cheap, or should I just BUY them already made?: A few months ago my wife and I were going through the same thing. We ended up purchasing a small PV set as a trial basis but then we realized that it would take waaaay too long to pay back our investment. We started doing some research and ended up buying a few different books/videos on how to make our own solar panels on the cheap. Most of the books are OK (some are pretty terrible, though). We ended up using most of our information from Home Made Energy, check them out: bit.ly/greennrg

Q:Can solar panels be used to power a music festival?: Yes, solar panels can be used to power a music festival. Solar panels can generate electricity from sunlight, which can then be used to power various electrical components such as sound systems, lighting, and other equipment required for the festival. By harnessing solar energy, music festivals can reduce their reliance on traditional power sources and contribute to a more sustainable and eco-friendly event.

Q:Can solar panels be installed in a desert environment?: Yes, solar panels can be installed in a desert environment. In fact, deserts are often considered ideal locations for solar panel installations due to their high levels of sunlight and low cloud cover. The dry climate and lack of shading make it easier for solar panels to generate and harness solar energy efficiently.

Q:Can solar panels be installed on ground-mounted structures?: Yes, solar panels can be installed on ground-mounted structures. In fact, ground-mounted solar panel systems are a popular choice for residential, commercial, and utility-scale projects. They offer flexibility in terms of location, orientation, and scalability, making them an ideal option for areas with limited roof space or shading issues. Ground-mounted structures can be customized to optimize solar panel angles for maximum energy production and are easier to install and maintain compared to rooftop systems.

Q:How much solar energy does a 2m by a 3m solar panel convert to energy on a sunny day? Assume that the solar cells are 30% efficient.I'm not looking for the answer so much as I need an explanation o how to solve this type of problem... Thanks!!: You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m? (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m? and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.

Q:Can solar panels be installed on senior living facilities?: Yes, solar panels can be installed on senior living facilities. In fact, many senior living facilities have started incorporating solar panels to reduce energy costs, promote sustainability, and provide clean energy solutions. Installing solar panels can help these facilities become more energy-efficient and reduce their carbon footprint. Additionally, solar energy can contribute to a more comfortable and sustainable living environment for senior residents.
