- Q: Do solar panels require cleaning?
- Yes, solar panels do require cleaning. Over time, dust, dirt, bird droppings, and other debris can accumulate on the surface of solar panels, which can reduce their efficiency. Regular cleaning helps to maintain optimal performance and maximize energy production.
- Q: Is it really necessary to make solar panels that expensive?
- it cost less then $000. to make a car if you add all the cost of the material the average car made in the USA is sold for 30,000. before the company make a profit they need to sell 6 cars to pay for the labor. With a solar panel system it cost depending on you kilowatt use then they figure out the life expectancy of the unit what your monthly ele bill would be and that is what it cost for your system and that is with out the carrier charge from your power company who charge you for both when you use or sell power to the grid and most of the systems sold are sold to tie into the grid. as far as how much does it cost to make a solar panel The reason they give the price per watt is that is how they charge to sell them The process is not as complicated as they make it The high cost is in the so called shortage in silicon they claim there is a shortage of the type of silicon used in making the chips but last I heard silicon is just sand and it is the eight most common element on the planet it is the same process used to make computer chips which you can by now for around a dozen for a penny put that does chips togethet and you have one of the around 00 chips in a solar panel so a solar panel costcost about fifty bucks to make solar panel 00 watt sells for around $50. for a starter kit they sell them 200 percent mark up minimum the big cost is in the installation .
- Q: By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?
- Probably not worth it. Sure, it is a great idea, but it will take decades to get your money back in energy savings. Today's panels are fine for a roof. However, I'd worry a little about the interface (where leaks could occur) especially in a retrofit. They, of course, will need to face south.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- Wiring the panels in series should be ok as long as they are exactly the same. Different impedance's could damage the panels. Remember that Voltages and Amperage's are indirectly proportional meaning that if you series your panels your voltage will rise but the amperage will be reduced.
- Q: I have created a solar setup in my shed i have 2x.5w solar panels i am hoping to charge my 55ah car battery how long would it take to charge the battery and how many watts could i used a day
- To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.
- Q: How do solar panels affect the insurance premiums of a property?
- Solar panels can potentially affect insurance premiums of a property. While it varies depending on the insurance provider and region, installing solar panels may increase the overall value of a property, which could result in a higher replacement cost in case of damage or loss. However, some insurance companies offer specialized policies or discounts for homes with solar panels due to their positive impact on energy efficiency and reduced environmental risks. It is best to consult with insurance providers to understand their specific policies and how solar panels may impact premiums.
- Q: does anybudy know about solar panels? plz reply me
- Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×0 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.
- Q: There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
- No problem linking them in series.
- Q: So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
- You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
- Q: Can solar panels be used for off-grid living?
- Yes, solar panels can be used for off-grid living. They are a popular and sustainable option for generating electricity in remote areas or locations where there is no access to the traditional power grid. Solar panels collect energy from the sun and convert it into usable electricity, which can power various appliances and systems in an off-grid home. Additionally, by incorporating batteries or other energy storage solutions, solar panels can provide a consistent power supply, even during periods of low sunlight or at night.
