Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
What is the open circuit voltage and voltage under load with the panel in full sun? Assuming it is typical of many 0W panels, the open circuit voltage is 2V and the voltage under load is about 7V. 0W/7V is 588mA. A typical car battery is 40 Amp Hours. Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah - would be maybe two days of full sunlight - with only a 50% charge, or about 2.2 Volts. Not a great battery charger - however - It makes a great supplement, and can offset the use of DC powered equipment in the vehicle while the engine is off. Things like low-wattage lights, cell phone chargers, tablets, and the like will drain the battery down that much slower. I have a number of powered but low current items on in my truck all the time. A panel helps offset some of that drain if I don't drive for a few days.
Q:Are solar panels only effective in places where there is an abundance of sunlight?
Solar panels are *more* effective in places with abundant sunlight, but can be used anywhere that there is light. The problem is an economic one. Solar panels are expensive and can only produce so many watts per square meter. If you have less sunlight, you'll need more panels to get the same amount of power. Germany has a relatively high latitude, and are reported to make extensive use of solar panels (funny, I spent 2 weeks there last month and saw very few panels). The reason for their use of the panels is that their government offsets the cost of installing them through subsidies. Other governments have similar programs.

Q:how can you make your own solar cells for solar panels?
Found this video demonstrating the process of making home made solar cells. I do not think this method would be very practical for an off the grid home system.
Q:Solar panel power question?
The specifications you give say the solar panel produces 5 watts at 2 volts (DC) so that isn't enough voltage to power an ordinary (20-volt) light bulb. You could get 0 of these panels and connect them in series so they put out a total of 20 volts and the total power available would be 50 watts. The panels would light the bulb that way, provided the bulb isn't over 50 watts and you can afford the panels. A panel does provide enough power for a 2-volt car light bulb less than 5 watts. However, the maximum current you can get from these panels is .25 amperes (5 watts divided by 2 volts = .25 A.) This isn't enough power to run your pump which takes 6.5 amperes - at 20 volts, that would be 780 watts. Another thing to check is the pump motor; many electric motors are designed to run on AC only and will be damaged if you try to run DC through them. Remember solar panels produce DC so the raw output from a panel will not work on an AC motor.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:is my solar panel big enough?
A equipment that super could have a max power production of around 2000 watts. i won't be able to declare if it fairly is sufficient to your desires via fact the figures you gave do no longer make experience. right here is why: the quantity of power being ate up at a given time is measured in watts--that's the ability point. To degree how lots electrical energy you utilize you utilize you need to use kilowatt-hours (or watt-hours, yet its greater handy to apply the former). So--in case you utilize a million kilowatt-hour, meaning you have been ingesting power at an favourite. fee of 000 watts (one kilowatt) for a million hour. Now, it may be VERY united statesa. for a house to apply 5,000 kilowatt-hours in a month--that's an exceptionally severe discern. Yor top power utilization could be 5,000 watts. A image voltaic panel equipment with a optimal technique of 2000 watts isn't adequate to power maximum residences. you easily want a minimum of two times that--and so lots greater in case you like to bypass off the grid. besides the shown fact that it must be an excellent investment besides. you are able to use very practically all the means advert that woudlld maximize your mark downs.
Q:How Do Solar Panels Work?
Solar panel or solar cells are semiconductor that generates electric current when expose to a light source such as the sun. It is a large diode that is capable of generating elctricity.If building a project you have to weigh the voltage and current requirements against the panel size ie.. 5x5 inches may be able to generate 00milliamps at 5 volts in bright sunlight.
Q:How many watt solar panel do I need to charge a 2v battery that wont be using much electricity?
Are you concerned about your higher energy bills? What about the atmosphere, are you worried about its resources that are nonrenewable? Solar energy and how to make solar panel are the solutions for you. Let us talk about the charges of pv strength and how practical it is for YOUR budget. The first thing you should know is that the size of your house has nothing to do with the cost on how to make solar panel. So for those people fortunate sufficient to are living in a gigantic property, pv panels are not here to overwhelm you with charges. What you do need to consider into consideration are items like how much sun you get a day, in which you stay, and how very much power you use a day. After you can appear to individuals conclusions, we can commence the math. Permit us do an instance together to figure out a ballpark expense for pv panels. Take a peak at your power bill as it is now and locate how numerous KWH you used, We will say that variety you found was 800 KWH. Now we are going to divide 800 by 30 and we get a whopping 26. 7. Don’t forget that quantity. It is how very much estimated KWH you use a evening. If you locate that you are exposed to six hours of sunlight a morning you would then consider the 26. 7 and divide it by 6. You reply should be four. 45 (or 4,450 watts). If you multiply that reply times . 5 you have successfully observed out how a lot of photo voltaic panel watts you need. The installation costs then are associated to the quantity you found above. Each and every watt usually costs $7-$9. All your installation fees need to be integrated with that estimated ending price. Now that you know how very much your method will charge, you will be relieved to know that it actually pays for itself inside six many years. There are also tax exemptions for people that select to use pv vitality. It is an investment that is really worth anyone’s time and funds Hope It's Help.
Q:Solar Panels, anyone?
Unless you live in an area with a very high UV index, like Las Vegas for example, solar panels are not cost-effective. You definatly should not attempt to install solar power yourself if you intend to power a residence with it (unless you live in a shack). A certified electrician is required in order to connect your equipment to your house's electrical system. It isnt just as simple as a few panels. You need a converter that turns the DC voltage generated into AC. You also need equipment to connect to the metering system for your house. If you want to see if it is cost effective, you will need your electric bills that show usage for a year and the price per kWH. There are a lot of websites that have calculators for solar power systems.
