Product Description

Product Description

The Sunforce 50012 1.8-Watt Solar Battery Maintainer is the perfect solution for charging the batteries of motorcycles, automobiles, snowmobiles, tractors and more. Made of durable ABS plastic and amorphous solar cells, this unit charges in all daylight conditions, even on cloudy days. Constructed with a built-in blocking diode to prevent reverse discharge, this solar panel is easy to install and completely maintenance-free. Just plug this solar charger into your vehicle's 12-volt lighter socket and position the panel to pick up the most daylight possible. Or, if you prefer, use the included alligator clips to connect it directly to the battery, so you can keep your lighter socket open for cell phone chargers or other accessories. Regardless of how you hook up the battery maintainer, you will always be able to start your vehicle. With a maximum temperature range of -40 to 176-degrees Fahrenheit, the solar panel provides 1.8 Watts or 125 mA of power to prevent the natural voltage drain of batteries over time. The complete kit includes a 1.8W solar battery maintainer, suction cups for easy mounting onto windshields, 7.5ft Wire, alligator battery clamps and a 12-volt DC Plug.

Convenient Power That Helps Keep Your Batteries Charged

The Sunforce 50012 1.8-Watt Solar Battery Maintainer lets you harness the power of the sun, the most powerful and plentiful source of energy available to us. Unlike nuclear and fossil fuels, solar power is clean and pollution-free, and the equipment requires very little maintenance to operate.

This battery maintainer is designed to stave off the natural voltage drain that 12-Volt batteries undergo over time. It can also maintain the charge of a 12-Volt battery while it is providing energy to small electronics like cell phone chargers. The Sunforce 50012 1.8-Watt Solar Battery Maintainer is constructed with durable ABS plastic and features amorphous solar cells. This unit also includes suction cups for easy in-car installation. Since it is designed for use inside of a vehicle, it is not weatherproof and should be kept dry. This battery maintainer is an ideal choice for automobiles, recreational vehicles, and more.

Sunforce Solar Panels are effective in areas of both high and lower sun exposure, making them ideal for use in the United States. View larger
About Amorphous Solar Power

Solar panels convert sunlight into an electric current, they do not store power. Amorphous solar panels are created by spraying silicon onto glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. They have a maximum operating temperature range of -40 to 176-degrees Fahrenheit, requiring virtually no maintenance. They can even withstand impacts from one-inch hailstones at 50 miles per hour.

Amorphous solar cells work in all daylight conditions--even on cloudy days. Please note that this amorphous solar panel needs to be inside the dash of a vehicle or by a window indoors as it is not waterproof.

Amorphous Silicon key points:

  • Lightweight, portable, and shade tolerant
  • For entry to solar or hands on solar
  • Best for smaller output needs, temporary set ups, and areas that do not receive predictable sun conditions

Customer Reviews

Probably the best value for money solar panels you can buy for kids.

Do not trust the suction cups to mount the maintainer, mine fell after I thought it was secure, just lay it on the dashboard.

I use this to keep my battery "safe" when parked at the airport for long periods of time.

Product works well but you need to check the output at the end of the cigarette lighter plug with voltmeter. I couldn't figure out why there was no power at the cig plug. After some investigating I realized there was a fuse inside the cig plug that was blown. Even though the blue light is flashing you'll still have no power at the plug. I slid the chrome ring off the plug and it opened up exposing a blown fuse. Hope this helps.

I installed this battery maintainer on the dashboard of my motor home and plugged it into the cigarette lighter while the motor home was in long term storage. Since the rig faces the morning sun, the maintainer did an excellent job of keeping the battery up to charge. I am well pleased with this Sunforce Solar battery Maintainer and would recommend it to anyone in need of such a unit.

I purchased 5 of these hoping they'd work as a cheap alternative to the more expensive solar chargers/maintainers. That was partly true; two of the five did but the other three all died within a month. Unfortunately this company(based in Canada) doesn't offer any support or warranty, contrary to what they advertise. Very poor quality and no support.

I purchased this solar charger for a camping trip I had planned. Out in the high deserts of Arizona, I wanting protection that my truck battery will be charged. I have a 1993 Nissan Pathfinder with a WalMart battery. We did use the truck battery too much while camping and that next morning the battery would not turn over the truck motor. Hooked up the Sunforce 1.8W solar charger and by day end the truck started right up. LIFE SAVER!!! I would recomend the product HIGHLY!!!

This is one of those products that is very much borderline for its advertised use. The panel rating claims a maximum of 125mA, but that's under fairly ideal conditions. Since this panel isn't rated for outdoor use, it will sit behind a car's windshield. Your typical piece of glass will absorb about 8% of the sun's energy. Adding to that a less-than-perfect install and you're lucky to get half that 1.8W rating.

I performed my tests in December, when the sun is at its lowest in the sky and the days are shortest(unless you live in Australia, then forget what i just said) . I live in northern California, which isn't ideal for solar, but is much better than many parts of the USA in terms of daily solar energy received.

Performance on an OVERCAST December day, near solar noon:
-Voc or open circuit voltage was 13.3V
-Isc or short circuit current, a whopping 1.8mA
-Charging current to battery was 0.18mA. The battery was at 12.0V at the time.

Performance on a SUNNY December day, near solar noon:
-Voc or open circuit voltage was 20V
-Isc or short circuit current was 60mA behind the car's windshield. Pointed directly at the sun and not behind glass, the panel managed 87mA.
-Charging current to battery was 50mA. The battery was at 12.0V at the time.

My sunny measurement was taken 3 days after the overcast measurement. My car drains the battery at 45mA continuously. Given that the solar panel is lucky to deliver decent power 8 hours a day, roughly three times the drain current is needed to keep the battery charged. This is beyond this panel's capabilities, even on a nice summer day.

I bought this array to trickle charge my 12V battery in my '05 Civic (I don't run the engine long enough between startups to maintain battery voltage). Attachment through the factory accessory plug was not feasible--the key must be turned to "accessory" for the plug to work, which then also powers up the radio. [Curiously, if I connected the array to the plug without the key on, I could turn on the radio, implying that the array was powering everything in the car that runs on "accessory"!] I therefore installed an always-on power socket; to do so, I installed a Bussmann BP/HHH ATM Add-A-Fuse to a unused fuse plug in my interior fuse panel, and attached to it a Radio Shack 270-1527 socket (after clipping off the battery clips).

In full sun, the array produces 70mA of current at 24V (60mA when properly attached to the battery). When attached in reverse, the array LED and diode together draw microamps of current (my ammeter could not measure that low of current).

Pros: Affordable price, good choice of connectors and clamps, compact design, long cable length, blue led indicator helps determine activity, very good shock proof packing, simple easy to understand instruction manual, light weight, environment friendly and saves electricity money.

The price of this item is reasonable and affordable. Perfect battery maintainer for the long winter months. Panels comes with its own clamps, adapters and connectors. Just to make sure, I checked the battery voltage before using this item and after using the item and the maintainer surely works great. The batteries show no sign of drainage or loss of voltage since one month. I have seen the voltage has gone up slightly indicating a good charge everyday.

Cons: One panel-wire had a loose connection (soldering). The LED light indicator turned ON sometimes and if I moved the panel-wire it went OFF. I understood it is loose soldering. If I had a solder iron, I could have easily repaired the loose connection. Since I don't, I returned the item and got another set which is fine.
