i have a small shed 10 ft by 10- ft. i only want enough solar to run small tools like drill,saw,etc.,is this product good enough for my needs
Asked by: dave
No, you need a large battery storage and inverter (DC 12V to AC 120V) Just like PV panel for house, Use battery power tool (Dewalt, Makita, Riobi.) This panel is use for 12V DC motor (solar attic fan and battery charger with voltage regulator)

What is the actual voltage of this panel? The specified amperage listed here on the Home Depot website is 2.86A and when you calculate the panel's wattage if it was 12v it comes out to only 34.32W. So either the stated voltage or amperage is wrong (I'm assuming the voltage is incorrect because most panels this size are around 18v).
Asked by: Ethan
Look in the specifications section for that info. Maximum Power Point voltage =17.5V Open circuit voltage=22.0V Current at Maximum power point=2.86A Open circuit current=3.17A They are using the Maximum Power Point power and current. 17.5Vx2.86A=50.05W

50-Watt Polycrystalline Solar Panel for RV's, Boats and 12-Volt Systems is rated 4.4 out of 5 by 34.

It’s main use is to recharge a 35AH portable solar generator for camping and it is able to replace the watthours used daily without issue. The mc4 connectors are easily connected and released. Overall, a good value.

The panel did not include those things and had to pay about $60 more and attempt to make it work myself. So misleading.

Rated 4 out of 5 by from Nice solar panels for a good price I purchased 2 of these panels to make a solar suitcase. I got them on sale for $70 a piece which was the best price I could find. They are working well and I am charging 2 35AN AGMs with them. I plan on powering a 12V Truckfridge to have cold stuff when I travel. Here is a picture of my test setup.

I have two of these panels in operation for charging batteries which in turn operate lights and an alarm system in two sheds. They are light weight, well made, and compact for the kind of power they turn out. I am using charge controllers from Morningstar Industries, as I have had good luck with their products in previous installation of another system. The aluminum frame gives you plenty of options for installing it to fit your particular need. Best of all, they were priced around $80.00. You can't beat the price for this quality, and it is available from Home Depot, not being shipped from overseas. I have a 100w Grape panel that will go up next spring to charge larger 12v gel cell batteries which in turn will operate emergency communications equipment.

Rated 5 out of 5 by from Another great product from Grape Solar Just what I needed to fill in the gaps in my Grape Solar 100 Watt panel array. these half size panels will allow you to fill in spaces left going around the vents and obstructions on your home, cabin or RV roof because they are the same width as the 100 watt panels only shorter. Also good fill in when using MPPT solar charge controlers rated at 500 watts and you need to series 2 panels to get the 36 volts other than the 100 watt panels that would only give you 400 or 600 watt selections. if you are on grid and using micro inverters, these units will fill in with the 100 watt Grape panels to give you 300 watts at 36 volts required so you do not need to buy as many inverters if you have the 320 watt sized inverters. I ordered 15 - 50 watt Grape solar panels to go with my 30 - 100 watt Grape Solar panels to fill in gaps and as replacement for aging amorphus solar panels going to existing MPPT charge contolers at 36 volts for a 12 volt system. Grapes no hastle, no cost exchange, including shipping, on defective panels makes the 5 year manufaturers defects and 25 year power warrenty a true value for the do-it-yourself buyer .
