Questions & Answers


How many panels I need to run during the day an air conditioning of 3500 btu

Asked by Gil April 9, 2020

Calculating the amount of panels required to power your device requires the wattage and time of use for your device. Reach out to for custom system design.

Can I mix Poly and Mono-crystalline solar panels in my solar array?

Asked by Angel March 31, 2020

Yes, mono and poly panels can be mixed, but you will be better off if they are on separate controllers, as they have different properties.

does this panel charge in cloudy conditions or does it require direct sunlight?

Asked by swedecar March 29, 2020

These panels will still generate some energy under cloudy conditions, but direct sunlight will have the highest production.

What wiring do I need to get to run these to the charger ?

Asked by Marky March 17, 2020

Use gage 8 is the best for electric flow. Little higher to buy but worth your system.

Can these be used in a 24 volt system? I have 38 of these - 30 160 watts and 8 180 watts. It was ...

Asked by Tammy September 19, 2019

This is Tammy....The For a while I have had them set up as 12v + 12v + 12v +12v in series then two sets like that connected in parallel. The 160 watts and 180 watts are not co mingled. They are then connected to a Midnight Solar MPPT CC. I also have appropriate breakers between the panels and CC, and between the CC and batteries. I should probably put some sort of breaker between the bttery bank and the inverter, which looks like that would be the only thing I would have to replace... It sounds like I am all set. Thank you to all.

Will this run a pool pump and filter

Asked by Miss September 5, 2019

No, this panel will not produce sufficient watt-hours to power a pool pump for a satisfactory amount of time per day.

Is having the ends of the solar panels fully supported sufficient or should they also have mid-le...

Asked by Stewbie August 15, 2019

I put them on my RV and did put supports mid-length.

I have 2 renogy 100 watt panels in parallel that I installed 2 years ago. I plan to add this pan...

Asked by primemaster June 24, 2019

I see too many possible complications to recommend this. But if you follow all safety and installation requirements of the charge controller and fuse you can see what you get. If the wattage output numbers are out of expected range there is probably a mismatch issue. If it works well you are in luck. Tip, a simple way to shut off panel power output for safe hookup is to darken all panels with a cover cloth or cardboard.

Ok, I'm about to install a solar array on my motorhome and just want to be sure I'm not making an...

Asked by Mike April 7, 2019

As long as your controller is an MPPT type that has a 150 volt input limit, six panels in series is fine. Standard 10 awg MC4 should be fine for a 25-foot run from array to controller, however a 15-foot run from controller to battery is problematic - we normally recommend a 5 foot maximum. Contact Grape Solar Technical Support directly for wire gauge advice on that. You will need six sets of Z-feet, and you are correct that no combiner box is needed since there are no parallel connections.

What amp fuse should I use with this panel?

Asked by Bowhunter April 1, 2019

I would use 20amp, as I use a Renogy Rover 20Amp charge controller with this panel and even on the most clear, direct sun it never gets close to 20 Amps
