- 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.
- Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?
- As Aviophage says, there is plenty of info around. Solar panels produce electrical energy from the sunlight's energy. The sun puts out around 00W per square meter, and the panels are up to 20% efficient at converting this. If you are looking for a Grid Connected power system, they are usually made up of 24V modules about 50W each. The full voltage produced is then around 50V to 500V DC depending on the sun etc. They are connected to a specialised grid connect or grid interactive inverter (look up Sunny Boy for an example) which converts this to mains power for use around the house, while any remainder is exported to the supply network. The supply company may buy this at premium rates, and governments may provide subsidies to approved installations. There may also be carbon credit certificates when you buy a system. Not all places allow such things to be connected to the grid, but this market is rapidly changing. The links below should get you started.
- Q: Can solar panels generate electricity at night?
- No, solar panels cannot generate electricity at night because they rely on sunlight to produce energy.
- Q: first of all, to be honest i have totally no idea on how a solar panel works.my task is to design something like a solar powered street lamp which store sun energy during day time and convert it into electrical energy then light energy so that the lamp can work during night time.any ideas on how to design the solar panel? which can store enough or more enegry in case there is no sunlight another day. and low cost as well :D
- solar panels change light into electricity, and do NOT store power. You need a solar panel capable of enough power to keep the light on all night. And that may be 6 hours of sun and 2 hours of dark. Then you need a set of batteries large enough to hold that energy. And a charge controller to regulate the charge into the batteries. And then a light that will operate on the battery voltage, say 2 volts. This is probably not practical due to the large solar panel required, and the large batteries. But here is a few numbers. Assume a 00 watt light at 2 volts. Assume you get at least 6 hours of sun every day and the light will be on for 2 hours. That means the battery has to store 00*2=200 watt hours. divide by 2 and that is 00 amp-hours, a large auto battery size. Allowing for 20% losses in the battery and circuitry, that means you nee 400 watt hours from the solar panel. Since it has 4 hours to operate, that means it has to deliver 400/4 = 350 watts at 5 volts. So there it is: 350 watt panel 00 amp hour battery charge controller sized for above 00 watt light. If you have to allow for a day with no sun, then you need more batteries. Two nights means 2400 watt-hours, two batteries, a larger charge controller and a 2800/4 = 700 watt panel. cost: $400 for batteries $200 for charge controller $2000 for panel .
- Q: How do I clean my solar panels?
- To clean your solar panels, start by turning off the system and ensuring the panels are cool to touch. Use a soft brush or sponge with mild detergent mixed in water to gently scrub away any debris or dirt. Rinse the panels with clean water and allow them to dry naturally. Avoid using abrasive materials or harsh chemicals, as they may damage the panels. Additionally, be cautious when working at heights and consider seeking professional help if needed.
- Q: I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
- I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
- Q: Can solar panels be used in multi-story buildings?
- Yes, solar panels can be used in multi-story buildings. They can be installed on the roof of the building or on vertical surfaces such as walls or balconies. The availability of space and the structural integrity of the building are important factors to consider when installing solar panels in multi-story buildings.
- Q: Just curious.
- Since you said does instead of do I think it would be fruitless trying to explain it...
- Q: How do solar panels affect the local economy?
- Solar panels can have a positive impact on the local economy by creating jobs in the installation, manufacturing, and maintenance sectors. Additionally, they can reduce energy costs for both businesses and residents, allowing them to allocate funds for other investments. Furthermore, the use of solar power can attract businesses to the area, stimulating economic growth and development.
