Q:How to find amp for solar panel project?
It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
Q:have you ever installed solar panels for your home?
yes. Its pretty simple connection. It does save money on electricity.
Q:Are solar panels actually efficient?
There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.
Q:Solar power panels?
Call a local solar company (a company that sells and installs solar panels). If you're having trouble finding one, you can call your local power company and they'll probably know of some. Have them come to your house and take a look at the panels and figure out what it would take to complete the installation.
Q:How do you connect a solar panel to a motor from an RC car?
Solar Rc Car
Q:How do Solar Panels work?
solar panels are made of solar cells.Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.
Q:Why won't my solar panels drive a motor?
Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
Q:Does a 50W solar panel generate 540kWh?
your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .
Q:so i'm wanting to eventually get solar panels.?
From a power company's perspective, it costs more to supply electricity during hours when electricity use is high. The times of day when power use is the highest are called peak hours. Historically power companies would sometimes charge large power users a higher rate during peak hours to encourage them to shift their electricity use to other times of the days. With the development of smart power meters and smart grid technology, it's now possible to offer the same incentive to individual home owners. so i'm wanting to eventually get solar panels.? If you live in an area where the electric rate varies depending on the time of day, then peak shaving improves your payback/return of investment on grid tied solar panels. Particularly in areas with high air conditioner usage, the peak hours generally correspond to the times when solar panels generate the maximum power. Look at it like this: Suppose your power company charges you $0.5/kWH during off peak hours and $0.30/kWH during peak hours. Because the solar panels generate the most power when the cost of electricity is the highest, it is easier to justify the cost of installing the panels because you are avoiding buying electricity at the highest rate. If your power company just bills you at a flat rate at all times, then it becomes more difficult to justify the cost of installing the panels and associated equipment..
Q:Solar panels for car fans?
The solar panel doesn't output enough power to run the fan directly, your best bet would be to just hook the fan back up to the battery, and then rig the solar panels up to help charge the battery and remove some of the load from the alternator. If you're trying to reduce your emissions/increase fuel economy then you'd be better of setting up a switch to disconnect your alternator when its not necessary to have it on. The alternator runs off a belt from the engine which requires some of the power output from the engine. Having this connected all the time increases the amount of gas used (marginally) but you'd be saving more gas doing that and using the solar panels to keep the battery topped up.
