- Q: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.
- Q:How do solar panels perform in extreme temperatures?
- Solar panels can still generate electricity in extreme temperatures, but their performance may be slightly affected. High temperatures can cause a decrease in efficiency, as the heat reduces the panel's ability to convert sunlight into electricity. However, modern solar panels are designed to withstand a wide range of temperatures, and their efficiency losses are generally minimal. In extremely cold temperatures, solar panels can actually perform slightly better due to the improved conductivity of the solar cells. Overall, while extreme temperatures can have a small impact on solar panel performance, they are still a reliable and efficient source of renewable energy in various weather conditions.
- Q:what size would the panel be/ I live in the caribbean so plenty of sun!
- You will need several panels and it will be expensive.. That's if you are running your pump for 4 hours each day.. You will really need a battery bank to give you Amps and or Watts.. The motor when starting will need up to 5 amps at once if not more... Too much for a solar panel by it's self and even 4.. maybe five would do it At watt per solar panel.. I am not a genius on this issue but there are base lines..
- Q:I have purchased a 2 volt LED lantern from argos, it comes with a built in 6 volt 4ah sealed acid battery. What I wanted to know is would I be able to charge it using my 6 volt solar panel?
- If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.
- Q:How much does it cost to replace a solar panel?
- The cost to replace a solar panel can vary depending on factors such as the type, size, and quality of the panel, as well as any additional installation costs. On average, the cost can range from a few hundred to several thousand dollars per panel. It is recommended to consult with a professional solar installer or company for an accurate estimate based on your specific needs.
- Q:Didnt solar panels use to cost around $250,000 5 years ago?
- I okorder to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
- Q:Can solar panels be installed on outdoor event venues?
- Yes, solar panels can be installed on outdoor event venues. In fact, outdoor event venues are often ideal locations for solar panel installations as they provide ample sunlight exposure. Installing solar panels can help event venues generate clean and sustainable energy, reducing their reliance on traditional power sources and lowering their carbon footprint.
- Q:How much would it cost (approximately) to convert my home (3 bed. 2 bath) to a green home that is run entirely upon solar panels on my roof? From the panels through installation does anyone know a price break down?
- the st element to comprehend is that there is no longer something complicated some photograph voltaic panel. this is not something greater beneficial than a selection of of photograph voltaic or PV cells on a board this is suited for the main spectacular area of your abode, generally on the roof. There are publications obtainable that coach you the thank you to construct a photo voltaic panel and a windmill for basically $a hundred and fifty, and it’s truly difficulty-free to make. appropriate of all, you may save 70% or greater on your potential invoice, including as much as hundreds of dollars each and each 2 months in reductions. I reviewed the two unfastened publications and paid publications and have arise with our ideal to construct your individual photograph voltaic panels.
- Q:What is the average lifespan of a solar panel?
- The average lifespan of a solar panel is typically around 25 to 30 years.
- Q:I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
