Wiring
To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.
PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

- Q: in a solar panel, i know that the electrons are knocked loose and used as energy, what happens to the protons?
- Here okorder /... Within this structure, the electrons are not really lost from the system. An electron just gets enough energy (from light) to be able to leave its atom, and float freely around the structure. Hence you have electrons in motion, which is the definition of electric current. If the lights go out, the electrons just settle back into one of the atoms that is missing an electron.
- Q: Are there any free classes to learn about solar energy and building a solar panel
- Why don't you just call a solar energy company and ask them anything you need to know, or check out websites- they usually have page with faqs or info. The company I used has lots of info on their website and they were very helpful.
- Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
- There okorder From panels, to inverters, to controllers, etc. Just look in their alternative energy section. If you happen to have aboutt 30,000 dollars to drop on the installation and you plan to live their more than 0 years, talk to your power company and they can set you up completely.
- 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: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.
- Have okorder / . It could obviously explain everybody!
- Q: What is the impact of dust and dirt on solar panels' efficiency?
- Dust and dirt on solar panels can significantly reduce their efficiency. When dust accumulates on the surface of the panels, it blocks sunlight from reaching the photovoltaic cells, thereby reducing the amount of electricity generated. The accumulation of dirt can create a barrier that hinders the panels' ability to absorb sunlight effectively. Regular cleaning and maintenance of solar panels are crucial to ensure optimal efficiency and maximize energy production.
- Q: Can solar panels be used to power a school?
- Yes, solar panels can be used to power a school. By installing solar panels on the school's roof or surrounding areas, sunlight can be converted into electricity, providing a clean and renewable energy source. This can help reduce the school's reliance on fossil fuels, lower energy costs, and contribute to a more sustainable and environmentally friendly learning environment.
- Q: How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please)
- first you should have good solar panels. because it can work well and make electricity quikly. when absorb sunshine it will produce electric charger and make electricity.
- Q: I wanna get a solar panel to charge or 2 car batteries. Then connect the battery to a 800watt power inverter so that I can power a tv. Will the 8watt solar panel charge my batteries and around in how long?I just wanna use the panel to charge the batteries, no to use the panel directly with my electronics. Thanks for your answer and help me with that.
- welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
- Q: How do solar panels affect the roof's structural integrity?
- Solar panels do not significantly affect the roof's structural integrity when properly installed. The panels are mounted on a rack that evenly distributes the weight, and professional installers ensure that the roof can handle the additional load. In fact, solar panels can even provide some protection to the roof by shielding it from the elements.
