Q:I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?

How long is the run? 2 gauge is a good choice for runs up to 25 feet at 20 watts, if you are much further in your run, move to 0 gauge to reduce resistance of the wire itself in the circuit. Otherwise refer to the prevailing electrical code of your local unit government. This is a must if you plan to maintain insurance. At lower voltage, a little resistance means a lot. 4 gauge might be okay for 20 VAC, but the voltage drop on a low voltage system from resistance of the wire itself is measurable at 20 feet. It is the difference between a light fixture working or not. If you are planning on adding additional panels in the future, you can get terminal buss with screw hold downs at various vendors like Mouser or Digi key. Each panel can be on it's own screw, while the buss is common on the other side of the connection. one for the positive and one for the negative.

Q:Our school is in the process of being built, but they have no plans to include any environmental benefits. I was wondering how to get a grant for solar panels (at least) or who I can talk to in order to get a grant.

I do not want to argue over the pay back period for solar panels but from the information I have been gathering, payback could be from 5-5 years, not 40. I guess it depends on the amount of sun that each panel will recieve, so maybe both could be partially correct. Another item to be aware of is that while the cost of your panels and the electricity generated by them will remain stable or decrease significantly for 25 years, the cost of your other energy sources will generally be increasing , perhaps very significantly. Since your school is being built now, it will need a roof. There are photovoltaic shingles for this. Look into it yourself. Do a google search for google green and see what they are doing already. Present this information to your PTA and any other organization who might have influence. This is really a time for your generation to step up and stop listening to nay sayers. Think for yourself, study, research it and broadcast everything you learn to others.

Q:Can solar panels be used in areas with high levels of air turbulence or strong winds?

Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is important to ensure that the solar panel installation is designed and built to withstand these conditions. Proper mounting systems and structural support can be implemented to secure the panels and minimize any potential damage caused by strong winds. Additionally, choosing robust and durable panels can further enhance their ability to withstand turbulent air or high wind speeds.

Q:What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!

Many solar panels wired in parallel, 2 volt solar regulator, 2 volt battery e.g. 30 Ah, 240 volt inverter, autotransformer that can go down to 50 volts. There are many parameter to the electric motor missing. AC or DC, current needs for full load. How many watts the motor uses and the number of hours required will influence the solar panel, regulator and inverter specifications.

Q:What's the best deal going on companies leasing out Solar Panels in California?

Q:i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?

The amount of energy needed to extract the raw materials from the Earth exceeds the amount the finished PV panels produce.Processing the materals takes additional energy.After manufacturing they have to be transported.Photovoltaic panels only generate </2 volt per square inch in bright sunlight.They become less efficient when they get dirty.

Q:im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?

You really need a little more infomation about your battery. It should have a recommended range of charging current. You should not exceed that range. Your solar cells must be a higher voltage than the battery, but you should not connect the cells directly to the battery. First, you need a diode in the line to keep the battery from draining into the solar cells when there is no light. Second, you need a resistor to limit the charging current. You have a 3.6v battery. Let's say the charging current is 0.A. Use a 5v solar cell and silicon diode. The diode will drop the cell voltage to 4.3v. The voltage across the resistor will be .7v for .A current, you need a 7-ohm resistor.

Q:What is the most affordable, yet highest watt solar panels available?

in case you raise a dumb-bell a undeniable style of feet, you have expended a undeniable volume of potential, does this variation if the gymnasium exchange into on yet another floor of the construction? Grounding is needed for defense and to dodge floor loops from happening, the quantity of potential produced would not exchange and any adjustments in potential will bring about a risky floor loop attempting to equalize it.

Q:Can solar panels be used for charging electric scooters?

Yes, solar panels can be used for charging electric scooters. By connecting the electric scooter to a solar panel system, the sunlight energy is converted into electricity, which charges the scooter's battery. This eco-friendly and sustainable method of charging can reduce reliance on grid electricity and promote renewable energy usage.
