Q:how does solar panels give power to the batteries?
When sun light reaches solar panels, it releases electrrons to make an electric current. They are made od silicon or germanium which has this property. Photons in the sun light when hit on semiconductor like silicon, releases electrons o make the current flow.
Q:Solar Panel Batteries?
If he is going to be running off batteries at night, he would be better off with traction batteries. Traction batteries are true deep cycle and can better withstand deep discharge. Golf cart batteries at Sam's Club (the other half of Walmart) are traction batteries. If your grandfather needs safe refrigeration, a mini fridge won't do it. A 0 fridge takes too much power to run off solar panels and most won't hold their cold very well if unplugged for long. I run a fridge off grid with hybrid deep cycle marine starting batteries. It's an Engel 40. The price has gone up over $00 since I bought mine. It's a real fridge with a compressor and freon 34a. But it runs on 2v dc or 0vac and only uses 36 watts running because of a special compressor design. It will freeze food if you turn the dial down to 2 out of 5. It can also deep freeze. I use mine to keep eggs, milk, cheese and fruit juice. Your grandfather would need 400 amp-hours name plate rating of batteries at 2v to run the Engel, and probably 00 real watts of panels to recharge his battery bank. The Harbor Freight 45 watt panel set only puts out 30 watts on a clear cool day. That won't do it.
Q:How to connect or use Solar Power Panels?
You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes.
Q:Where can I get damaged solar panels?
Used solar panels are usually a great bargain. Unless there is obvious major damage, you are most likely making a very safe and thrifty purchase--and if you can test the panels with a multimeter in full sunlight before purchase, you are almost guaranteed a functional panel. Nobody really knows what the lifespan of a solar panel is, since many of the very first panels are still in operation. I have three very old Arcos on my house, and they are still performing well. However, used panel prices have
Q:It's all about Solar Panels?
In the US and western Europe, the average cost to install a solar system.....panels, wire, battery bank inverters and all of that is $5 ( five) US a watt. ( One panel, 2 x 3 feet putting out 75 Watts costs $700-800 US ) Mos American homes use about 000 kilo Watt hours of electricity a, heating, cooling, refrigeration, water lights and all that. that is 2,000 kilowatts a year. A solar panel system would therefore cost $60,000 US to install. That is WAY beyond almost everyone's means, which is why the US and Europe is not covered in solar panels. There is also the amount of sunlight per day and the height of the sun in the sky. There is a formula to figure out how much usable sunlight a day you get; the further north the less......and that number averages out to about 5 hours a day year round. So back to the 000 kW a month.......30 + kWh a 5 hours a day you have to generate 6,000 watts .... divide by 75 watts a panel = 35 panels x 75.00 per = 25,000 $ US plus wiring, batteries and all that........
Q:How solar panels and furnaces work?
Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
Q:Why do solar panels stop working?
Panel degradation can occur in many ways, but they generally take a long time (40yr old panels are still working...). One problem is diffusion. Since the cells are at a finite temperature and receive energy from the light, atoms in the structure can migrate around the cell. If you mix up materials from either side of the junction, you can reduce or remove the internal field and so charge separation no longer occurs, meaning no more current output. This is generally a very, very slow process. My current research is on the back contacts of cadmium-telluride solar cells. CdTe forms a junction with metals, and this junction has a built in electric field that tries to stop the current going out of the cell. This is bad! It reduces the power you get out. To overcome this, copper is sometimes added. This really cuts down on the restrictions on current, but copper is very diffusive. Within weeks at room temperature it can jiggle its way along grain boundaries (the solar cells aren't one big crystal, but a load of small grains. Our lab makes ones about 0.006mm across). Whilst copper at the back contact is good because it cancels out the effect of the field there, once it gets to the cell junction it has a worse effect. It can act as a 'recombination centre' or 'shunting pathway' - it either absorbs the free charges or takes them somewhere useless and cuts the power output. Copper is a very obvious and quick acting cause of solar panels reducing in output. I believe a similar effect is true for other cells, just with different materials. The quality of the junction degrades slowly as heat and light give energy to atoms in the lattice and make them jiggle around a bit. Once you have things out of place, performance degrades.
Q:Are solar panels worth it?
I say yes, I had a system put in a few months ago. I paid $6K and my utility paid $0K. I should break even in about 6 years. The system is guaranteed for 25 years, so I will have at least 9 years of free energy. I went from a bill of around $200 per month to under $20 in the summer. I will pay a little more in the winter months because less daylight, but I don't use as much energy in the winter. Each year electricity goes up an average of 5%, so while my neighbors have a larger bill each month, I'll be staying under $50 for a long time. Even without the rebate I would have a break even time of about 0 years, still 5 years of free energy.

Q:what do we mean by efficiency of a solar panel?
