Q:How to connect 2 power supplies together? (Solar panels)?
You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?
Q:How much would solar panels cost for these?
They would cost quite a bit but the user would likely be eligible for some energy credits from the power company and their cell phone carrier which would bring down the costs
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
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:Why don't scientists use the design of a tree for solar panels?
From the vantage point of a scientist and an engineer, you have a whole host of problems to overcome. The mass of solar cells cannot be supported by most leaves much less allow the leaves to turn toward the sun as they naturally do. The wood and other structures of a tree are terrible conductors and wouldn't serve as efficient power transmitters. There are issues of damaging the health of the tree by interrupting the process of photosynthesis in favor of solar energy collection, and many other issues. However, I can tell you that solar power does use several principals that you have observed in trees. For example, solar collectors are almost always oriented to face toward the sun. Many adjust with the time of day and seasons to be optimally oriented to collect the sun's rays. Much like leaves in many plants are not static but change position to optimize their angle to the sun. Also, many solar cells are now designed with a membrane structure which offer several advantages. So you see many of your observations have found their way into practical application in solar power production.
Q:Do solar panels keep a structure cooler?
it would depend on the type of paneling. And compared to what. Since it absorbs solar energy, that includes some heat. Compared to white paint, which may reflect more of the heat, it depends.
Q:Solar Panel watts needed?
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.
Q:Electricity question about solar panels?
You will have to run the solar panel to a 2v or 24 v battery array that use an inverter to convert the battery power to 20 for the heaters.
Q:solar panels disconnected from battery?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:solar panel for 2 batteries(2 V)?
0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.
