Hello Matt,
If you leave the state and zip code where you plan to use these panels, we can use that information to give you an educated estimate of the battery bank size you will need to capture all the energy produced by your panels.

The answer is it depends. What needs to be considered when wiring these panels in series is the operating currents of each panel. In series, the currents of all the panels will be the same. If one panel has a lower operating current, than the other, all panels will operate at the lower current. If the operating currents are similar, then the power loss will be minimal. However if there is a large difference in operating currents, there will be a larger power loss.

Thanks rickst29! All the information he has provided is exactly correct Mike S. If you are certain that you have an MPPT controller, then you can wire your panels in series and still charge a 12V battery bank.

We have the 100 v system, brand new. So far loving it, but we have questions. We have a port on our Rpod trailer that we plug into. The panels and charge controller are on a portable stand that we will put in the tow vehicle to transport. Can we just unplug from the Rpod port, with the panels plugged into the charge controller, and stow it like that? Will the charge controller be damaged if electricity is coming into it from the panel, but not going into the trailer? Is there a hazard of shock or fire? thanks so much! There is a possibility of damaging the charge controller if the solar panel is connected without a battery. If there is a solar panel connected to the charge controller without a battery the electricity will flow without anywhere to go. This will cause the input circuit of the controller to break. Please let me know if you have any other questions or contact our technical support department at (800)330-8678. Thank you, AW

Pete claas,
This also depends on what type of charge controller you will be using. 12 AWG is usually what we recommend our customers with our 100w panel. If you would like further assistance please contact our technical support department at 1(800)330-8678.
Thank you, LP

Unfortunately the controller is not water proof.

Should the negative wire coming from the panels be grounded? the panels connect to each other, so they do not need to be grounded.

Can I hook my array in 48 volts with the 40Amp MPPT Charge Controller, and if so what would be my max wattage? Unfortunately our MPPT controllers operate at 12/24 volts and not at 48 volts.

The solar cells we use on our Monocrystalline Panels seem to be black, but they are just a very dark blue so they almost appear black in the sun. We do not use the new black solar cell you are talking about.
As far as your question on temperature, it is true that the efficiency does drop with a temperature increase. Monocrystalline Panels are generally more efficient, but under high temperatures the Monocrystalline Panels eventually become slightly less efficient than the Polycrystalline Panels.
We don't see the price decreasing that much more and believe it will level off at about $.75/watt. It would take another innovation in Solar Panels in order for the price to decrease dramatically.

It depends on a lot of different factors. For one 100w panel with a 3% acceptable loss You can have up to -85 feet with a Guage 8 wire -50 feet with Guage 10 wire -30 feet with Guage 12 wire We recommend you use our guage calculator www.renogy-store.com/category-s/1864.htmOur 100w panel runs at 18.9 volts and 5.29 Amps

Hello,
For this situation we would recommend purchasing an extra panel. Although a tilt mounting device is a great tool, installing is on the roof of your RV is a difficult task. We generally recommend that tilting devices be used when you have your solar panels on the ground.
