Q:For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.

if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.

Q:Can solar panels be installed on a barn or agricultural building?

Yes, solar panels can be installed on a barn or agricultural building. In fact, barns and agricultural buildings are often ideal locations for solar panel installation due to their large, open rooftops and proximity to open spaces. Installing solar panels on barns can help farmers and agricultural businesses reduce their electricity costs, generate clean energy, and contribute to a more sustainable farming practice.

Q:The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?

Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.

Q:how would you build a solar panel

As a sandwich. Glass Space /4 inch Glass Space with copper radiator painted flat black. Box made of wood. with the inside painted black. Insulate the back side. Use water with RV antifreese. Circulate water through with a small pump. Face it toward the sun. Thermal water solar Panel.

Q:Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?

Well I think solar technology is a viable solution to our energy problem. The only issue is that right now it takes too long for the panels to pay off unless you have a fairly big facility to power. Solar panels are getting cheaper and cheaper though, soon they will pay themselves off in less than ten years and I think then you will see more people buy them which will bring the price down even more. Solar done on a large scale is something that needs to be invested in ASAP. They can create jobs, power our nation and slow down global climate change.

Q:name things someone could use solar panels for or make with solar panels? (use solar energy i mean?)

Solar panels can bee installed into your houses or apartments power box (if it's outside). But Solar panels cost more than $00 so i hope you saved up.

Q:I need to have more information about what are solar panels. will you help me?

If you want to see one up close find a solar powered calculator or a solar powered garden light at your local supermarket, they all have solar panels on them. The bigger the panel the more power, that's why the panels on the ISS are as big as a garden, they produce thousands of watts

Q:Are solar panels suitable for all climates?

Solar panels are suitable for most climates, but their efficiency may vary depending on factors such as sunlight intensity, temperature, and weather conditions. While solar panels can generate electricity in cloudy or colder regions, they are most efficient in areas with abundant sunlight and moderate temperatures. Advances in technology have made solar panels more adaptable to different climates, allowing for their effective use in various regions around the world.

Q:Can solar panels be installed on a fire station or emergency services building?

Yes, solar panels can be installed on fire stations or emergency services buildings. In fact, many fire stations and emergency services buildings have already adopted solar energy to reduce their carbon footprint and save on energy costs. The ample roof space available on these buildings makes them ideal candidates for solar panel installation. Additionally, the use of solar power can provide backup power during emergencies, ensuring uninterrupted services even during power outages.

Q:Can solar panels be installed on a remote island or location?

Yes, solar panels can be installed on a remote island or location. Solar panels are a versatile and sustainable energy source that can be easily installed in off-grid areas. They do not require a constant supply of fuel or a connection to the main power grid, making them ideal for remote locations where traditional energy sources are scarce or expensive to transport. Solar panels can provide reliable electricity to power homes, businesses, and infrastructure, allowing remote islands or locations to become more self-sufficient and environmentally friendly.
