- Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.
- If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.
- Q: what do I need to do to disconnect a solar panel from a battery to protect the panel?
- 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: I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
- Your demand is high. You require at least 5KVA (5000watts) out put with an appropriate battery storage and inverter..
- Q: Can solar panels be used for charging outdoor power tools?
- Yes, solar panels can be used for charging outdoor power tools. Solar panels convert sunlight into electricity, which can be used to power various devices, including outdoor power tools such as lawnmowers, trimmers, and chainsaws. This provides a sustainable and environmentally-friendly alternative to traditional methods of charging these tools.
- Q: Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or surrounding areas, an office building can generate enough electricity to meet its energy needs. Additionally, by integrating battery storage systems, excess solar energy can be stored and used during non-sunlight hours, ensuring continuous power supply.
- Q: If not how do they give power to a house/a company?
- They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.
- Q: How can I calculate the amount of watts needed for a solar panel to power a water and air pump in gal/hr and a 600 watt LED light?
- 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: does anybudy know about solar panels? plz reply me

- Q: Can solar panels be installed on golf courses or recreational facilities?
- Yes, solar panels can be installed on golf courses or recreational facilities. These locations often have vast open spaces with ample sunlight, making them ideal for harnessing solar energy. Additionally, installing solar panels in these areas can help offset the energy demands of the facilities, reduce carbon emissions, and promote sustainability.
- 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..
