Rated 5.0 out of 5.0 by Curtis Durable, Powerful Solar panel
I purchased 12 of these panels. 10 were for an 8 battery bank with 5000 watt inverter. Installed one to power driveway SMD LED lights and 2 batteries (one of which is my travel trailer) used in conjunction with 20A charge controller. The other panel is used in conjunction wwith amorphous panels to charge a 3 battery bank mobile solar cart. The panels came ready for install (less hardware mounting brackets). Very dependable, strong solar panels. Specifically purchased mono crystalline for their low light capability.

Rated 5.0 out of 5.0 by solarRVfan Outstanding panels for a great price
I purchased four of these panels for our travel trailer. These panels are well made and produce more watts than other panels of similar size. They installed easily and seem to work great and the price was outstanding. They were shipped promptly and arrived within a few days.
Be aware you will need to purchase MC-4 connectors to wire these in. These were not available from Home Depot. Also pay attention to the positive grounding instructions which is different from other types of panels.

Rated 4.0 out of 5.0 by TidewaterTodd Sun = Power
We bought this to provide power for our camper and keep a 12-v deep-cycle topped off while "dry-camping" in national parks. On its maiden voyage (in fair weather), the GRAPE panel (combined with a Sunforce 10-amp charge controller) is overkill, providing more energy than we could possibly use and allowing us to use the 12-v lights and accessories long after dark without fear of running our battery down. According to the voltage reading on the controller, power-production is instantaneous, even in less-than-ideal lighting conditions.
If there is a downside, it is connectivity; apparently there is no current "standard connector" in the solar industry. While the GRAPE panel came with quick-connectors on the positive and negative (neutral) lead, there were no matching connectors on the controller, so in the end, we chose to void the warranty and strip the connectors as it was the only way to connect the two (necessary) pieces of equipment. However, the splice allowed us to add about 40-ft of grounded 12AWG extension--with the help of an electrical engineer--which provides LOTS of flexibility in placement, even on a tree-filled campsite.
Packaging was intact and did its job on the cross-country ground-delivery.
Instructions (from GRAPE) were clear...although you'll need to provide your own hardware to ground the panel, unless you're using it as part of a larger, grounded array.
Shipping from HD was on time and uneventful in all the best ways.
Here's the bottom line: we're pretty new to solar power, and did a lot of research prior to making a purchase. While we probably could've generated enough power using a smaller (or, lower-wattage) panel, the price point on this panel from GRAPE (a US company) gave us a lower cost per watt than panels from other manufacturers, and we're very pleased with our purchase.

Rated 5.0 out of 5.0 by maghunter Good Price for wattage
Priced around and it was a good price for a 100 watt panel. It was also the lightest weight panel I could find.Free shipping is what made my decision. It also has a shorting diode in the junction box(should really be mentioned in the Home Depot information) which is a plus.
Overall greatly pleased with panel, was a little concerned that the lighter weight would make it weak but it appears OK. Might not select it for a HEAVY snow area due to weight load of snow.
I use it for charging batteries at my deer camp. Will probably require a second panel to be sufficient for when the wife and kids are hunting for the extra run hours on the Heater blower motor.

Rated 4.0 out of 5.0 by LuvToRV Parts that are needed to make it function at it's best.
I found if you search for a positive ground MPPT charge controller and purchase one of those it will maximize your output. For those that have a greater requirement for power just buy more panels and a larger amp charge controller. Two panels and a 15 amp controller, this combination is great and does just what I need.

Rated 5.0 out of 5.0 by HomeFree GREAT SOLAR PANEL FOR RV OR BOAT !!!
This panel is compact, powerful and lightweight. Just what you want for a mobile installation. It comes with MC-4 connectors on cableing from a sealed junction box, so you will need to get a pair of these connectors to plug this panel into your system. Removing these connectors voids the factory warranty. So be sure to order these state of the art MC-4 from a vendor on-line, as Grape does not sell the connectors. The pair is of course, one male and one female, to plug into the existing connectors. The vendor who sent me these connectors, did not provide any instructions for installing these MC-4 connectors. They must be soldered to 10 Gage wire and you better do the job right, or you can have someone with the proper skills do the job for you. I had trouble since my soldering iron was small and the 10 Gage wire was hard to get hot enough for the solder to flow. Home Depot or Grape Solar should sell the connectors with full installation instructions. Otherwise I am really very pleased with this solar panel and have ordered a second panel to add to the 300 watt array currently atop my VW Bus, making it 400 watts. The panels charge 4-125 amp deep cycle batterys. Happy Trails !!!

I built a small ground mounted solar array using DIY panels and I replaced 2DIY panels with 2 Grape Solar 100W panels. I was able to increase the electric output significantly with the Grape Solar Panels. GS-S-100-TS currently out of stock can't wait till the get more in.

Well made panel that has output as rated. Pleased with the panel over all and would recommend to others.
