Yes you can use 12 volt batteries. We use an Xantrex. Controler C60. Have it set up as a 24 volt system And have a total of 4 panels. I run my whole house

Yes, with that ammount of panels on an off-grid system you would need a combiner box. We recommend a max fuse size of 20A.

how can I purchase just one panel? Most of are sold in kits of two or more.

Answer

Due to the shipping costs, this is currently not available "point-and-click" as a single panel. Please reach out to retail@grapesolar.com if you would like a custom quote through the Home Depot.

how many amps each panel generates

Asked by ericcr October 5, 2020

Answers

15 amp circuit breaker is recommended per parallel panel. 15 amps per series string. In New England in Oct I once reached 270W at noontime, if that is what you meant by your question. I have 20 of them in two strings of 10 panels and a 6000 W grid-tied inverter.

How many of these panels can be used with a TriStar-60A charge controller?

Asked by John September 1, 2020

Answer

For support on a TriStar-60A charge controller, you will have to reach out to the manufacturer so you can compare our panel's specs to your charge controller.

Is the 300 watts per hr or per day? On a good sunny days?

Answers

300W is peak and rarely happens. Anticipate ~280W for 4-4.5hrs per day. So about 1100Wh per day.

Anyone know can i just order 1 panel or any other panels 300W+ ? I only see HD selling 100W pane...

Asked by mark May 17, 2020

Answer

300W panels are shipped on pallets due to the size and weight. It isn't economically feasible to list single 300W panels due to the high shipping cost. Reach out to retail@grapesolar.com to get a custom quote for a single 300W panel.

How can they be 300 Watt when the current is 9.24a and the voltage 24v? (24x9.24=221.76w)

Asked by Mike May 6, 2020

Answers

300 W is a nominal rating for ideal conditions - intense light perpendicular to the pannel. You practically never get it.

Would these panels be good on a trailer? How many actual watts output?

Asked by Enav May 15, 2019
2
Answers

If you have proper hardware, the two 300w panels can be mounted on a trailer. At "Standard Test Conditions," the panels produce an instantaneous wattage of 600w. The volume of power, or watt-hour produced in a given day, depends upon your location, the tilt of the panels, and the time of year. Use the National Renewable Energy Laboratory's PV Watts Calculator, found at pvwatts.nrel.gov, to discover how much monthly kilowatt-hours the system should produce in your zip code. For the first queue, the two panels are .6 kW DC total.

Do these solar panels come with everything you need to convert the power to an average PC charger?

Asked by William March 30, 2018

Answers

No, just the pannels. You also need charge controller and storage batteries.

These solar panels have outperformed any panels I have bought to date from other manufactures. Most panel advertise a 70 percent efficiency rate and do not perform anywhere near that. Well these panels do. I did not do fancy tests just replaced with panels from another manufacture and these panel amp wise way out preformed them. The other panels I will just say were well built and a brand name manufacturer.

Does what it’s supposed to do. Made in the USA. Time will tell how fast it degrades but for now it’s working at capacity.

Excellent Panels
Just received the 2 panels. Solid, quality made. I hooked them up in a series arrangement-horizontally ground mounted, for a small, portable 200AH LiFPO4 solar generator I built. I'm very impressed! Using a Victron 100/50 MPPT solar controller, they are routinely putting out well over 600W in the middle of the day. I've even watched the panels spike up to 700w several times. I will be buying more.

These panels are working great! I ordered as a replacement on a Suniva OPT280-60-4-1b0 gone bad. only needed one panel but we were able to add the second panel to the PV string using SolarEdge P320 optimizer. They are a perfect match to the Suniva.

The price is ok. It really is a decent price. Not earth shattering good, but pretty fair. It IS a GREAT product and I believe you can see the "Made in America" quality. I definitely will buy more as money allows. Great product.
