FAQ

Im fourteen and looking for a career I already know solar panels capture the sun and turn it into energy but i would like to know more.
A solar panel is a collection of solar cells (photovoltaic cells) connected together and put in an enclosure. The solar cells work by taking advantage of the photovoltaic effect. The effect is that in a semiconductor P-N junction, when photons of suitable energy strike the junction, an electron and electron-hole pair are generated. This creates a voltage difference between the two sides. When this voltage is applied to a circuit, the electrons are able to flow through, creating usable energy.
How can I calculate the amount of watts needed for a solar panel to power a water and air pump in gal/hr and a 600 watt LED light?
Mimi: Solar Power is not really that economical, and has many other disadvantages as well. You did not specify much info in your question as to the size of the water or air pump. So let's make some assumptions to get you some numbers. ) Let's say the water and air pump are about HorsePower (HP). The HP pump , considering efficiency losses, will draw around ,000 Watts , or kW. 2) The 600 Watt LED Light is quite high --- they are usually much smaller lights 40 Watts or less. BTW --- these LED lights are very expensive light as well. Just so you are aware. Between the pump(s) ( maybe 000 to 400 Watts) and the 600 Watt light ----- and without knowing the specifics --- you are probably looking at around 2,000 Watts or 2 kW. A 2 kW Solar PV unit will run around $20,000. The PV unit will only run at full capacity during daylight hours. They usually average about 5 hours per day. So you will only be able to run your pump and LED Lights during the middle of the day --- maybe 0:00 AM to 5:00 PM. If you want to run the pump and lights after sundown, you will need battery back-up. The electric storage batteries will likely run about an extra $5,000. They will last about 5 years. If you decide this doesn't work out well --- you can stay with the local utility --- at $0.0 per kWh. It will cost you about $0.0 per hour to run the pump --- maybe 30 to 50 cents per day. It would cost you about 6 cents per hour to run your light. Maybe 30 or 40 cents per day. You could essentially run your pumps and light several hours each day --- all for about $ per day, or $365 per year. This sounds like a less costly alternative.
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.
Okay so.. if light deflect the light of the sun and black absorbs it, then aren't solar panels just absorbing more light, sun and heat into our atmosphere? Wouldn't this lead to an increase in global warming? Shouldn't solar panals be white? No rude answers please.
There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
it is just for a simple project, but i am looking for a cheap, low cost, around one to two volts solar panel regulator uld y'all please help?
Solar cells shouldn't need a voltage regulator for simple projects like driving motors or powering CMOS electronic circuits. I would need to know a little more on your goals for the project to help. However, I will put a few links that may be helpful to solar cells and some voltage regulators. The first link is general solar cell info and includes manufacturer lists at the end. The second is a link to educational solar cell kits and cells that may be useful for you. The last one is Digi-Key which is good for finding components to make your own voltage regulator. Hope this helps with your project!!
Solar panels can have both positive and negative impacts on roof aesthetics. On one hand, solar panels can enhance the visual appeal of a roof by adding a sleek and modern look. They can also make a statement about a homeowner's commitment to renewable energy. However, some people may find solar panels to be visually intrusive and believe that they disrupt the overall harmony and symmetry of a roof. Ultimately, the impact on roof aesthetics depends on individual preferences and the design of the solar panel installation.
Yes, solar panels can be installed on warehouses. In fact, warehouses are often ideal locations for solar panel installations due to their large roof spaces, which can accommodate a significant number of panels to generate clean and renewable energy. Additionally, warehouses tend to have uninterrupted sunlight exposure, making them well-suited for solar energy generation.
Yes, solar panels can be installed on a shipping container. In fact, many people and businesses are now utilizing shipping containers as a platform for solar installations due to their portability and ease of installation.
