  1. Dave

    I got this for my shed, just to keep my travel trailer batteries charged in the winter and to add lights to the upper level of my small shed with a string of LED lights… I’ve been using it for years and it’s still working, keeping those batteries charged and the fans going during the summer months. (It’s just an 8×12 shed, with a barn roof over the shorter upper level, but I have lights when it’s dark out and fans to blow out the hot air in the summer months.)

    Consumers will likely never have perfect conditions to test their panels. A more useful comparison is calculating how cost/actual watt delivered varies amongst options available. This shows relative value. It’s a useful metric in most cases, but doesn’t hold in cases involving factors other than money. E.g. backpacker who needs absolute max watts/lb.I ran a comparison of 3 sets of panels in a 10 minute period with no clouds in the skies near noon, near fall equinox near the 49th parallel in N. America. (Not the best conditions for an ideal test.). All panels were close together, of similar cleanliness, temperature and set at the same angle. No shadows were involved. I drained a RoyPow LiFeP04 battery to under 50% to avoid any current limiting from the Rich Solar MPPT 20A charge controller. I took the most stable values of V and A to produce W.Data (remember that actual watts measured aren’t as important as the comparison. Every thing gets better with better sun.)Harbor Freight amorphous 75W(3×25) rated: Measured 35.2W, Cost/Measured W $2.56, % of rated W 46.9%Tishi Hery monocrystalline portable 120W: Measured 86.4W, Cost/Measured W $1.70, % of rated W 72.0%Ecoworthy monocrystalline 25W: Measured 19.4W, Cost/Measured W $1.39, % of rated W 77.6%. This is the best value panel, but is likely 10-20% more expensive/W than the current 100W monocrystalline panels. But, a decent benchmark.It’s important to note that I purchased these all at huge discounts to normal prices, but the real thing to note here is that for me, I paid a 22.1% premium/W for the Tishy Hery over the Ecoworthy. I think that’s very fair for a portable system that includes cables and direct charging of portable electronics.. The Harbor Freight panels were an 84.0% premium.My guess is that for people with good sun nearer the equator and with current pricing under $1/rated W, people can hit $1/measured W under best conditions. Buying in bulk will drop this further.

    Does what’s it’s advertised to do. With the solar charge controller I purchased, it keeps my batteries topped of without having to search the forest for an electrical outlet. Why Amazon wants me to rate warmth, sheerness, or thickness, I don’t know, so I didn’t rate. It’s a well designer and built solar panel that turns sunlight into electricity and keeps the lights on.

  4. Tracy P.

    Have my shed wired with a few of these panels – and just added one more actually hence this review.3 years continuous use with no maintenance done whatsoever until now with no problems. 3 full years without cleaning cost it somewhere in the neighborhood of 33% efficiency loss, which surprisingly was totally remedied with cleaning/polishing it.Note: Luckily I do not have any large trees nearby to cover it with sap and bird droppings so I only had to wash it then use a headlight buffing kit to remove the oxidization, returning it to nearly new condition.

  5. Jim Kivi

    Pleased as punch with this panel. We are totally photovoltaic powered, and have several smaller panels for charging remote batteries, and boat and transportation vehicle bats. If you plan on leaving it unattended, I strongly suggest one of the inexpensive Chinese charge controllers to prevent overcharging, and night time drain. Make sure your charger will handle 20 watts. For smaller applications, it is easy to wire in an inexpensive lamp cord. Watch the polarity!! I use the “fat” prong for ground, and cut the cord about ten inches from the female end. That gets wired to the junction box. Then the male end goes to whatever clamps you want for your battery. Most lamp cords have the FAT prong side ribbed along the cord, so beware of polarity here too. You can also wire it to a cigarette lighter style plug to charge a car or boat battery through the lighter socket. Panel frame is stout and I am pleased with the product and pricing.

    Solar Panel uses for powering on 2 small 12VDC computer fans, ceiling mounted under a wood cabinet for summer, & hot weather cooling, and winter time indoor heat circulation. This small panel works Very well for its size and amp/volts it produces. It did not require a solar voltage controller for it. Easy install when wiring it up. Mounted on slide-in Camper roof with some HomeDepot steel Simpson lumber frame connectors, by carefully drilling the solar panel metal sides. Would buy again, if i can find a good deal on some Used PC tower DC fans.

  7. M_McDonnough

    I finally got around to testing one of these for powering some LEDs and cameras around the farm. I will likely be purchasing more as needed. They are a good value for the cost.

  8. Lester M.

    Perfect size for small solar setup in barns and greenhouses. I own two of these and have had them working for well over three years. Keeps my batteries charged up as expected. Would recommend for any small solar hookup application.

  9. TheAceofGates

    I own a metal shop & we often do automatic gates. These 25W solar panels are perfect for solar applications, and at this price are a no-brainer. With our adjustable bracket that we fabricate, you can fine-tune the direction of the panel to achieve maximum voltage.

  10. Famous Amos

    This panel is a great value. You should pair it with a similarly maintenance-free battery charging system. Keep a battery tending system that doesn’t involve a huge extension cord.
