This high quality waterproof 140 watt AKT solar panel is ideal for people who want to save money on their electricity bills and the environment, or were it would cost too much to install electrical cables to a shed or outhouse. This 140 watt panel is powerful and enough to be used to power hundreds of devices that you may use in a shed, boat or caravan such as lights and pumps and is capable of generating free renewable solar power even on a dull or cloudy day.
Due to its rigid anodised aluminium alloy frame and 3.2mm thick tempered glass giving it exceptional strength, it is perfect for permanent outdoor use on roof or in the garden to provide free solar power. This low-iron tempered anti-reflecting glass has a Back Surface Field (BSF) silicon nitride anti-reflective cell coating helping to increase the solar conversion efficiency of the panel and reduce overheating by the suns rays.
Connecting AKT-140-M Panels Together
For off-grid charging of batteries as in a caravan, camper van, boat or remote house type applications, why not connect the 140W AKT Solar Panel together with other 140W AKT solar panels to form larger arrays of many kilo-watts producing a higher voltage or greater battery charging current. The following table gives you an idea of what is possible with this versatile 140W panel.
|Panel Type:AKT-140-M Solar Panel|
|Panel Rating: 140W (8.0A at 17.5V)||Panel Dimensions: 808 x 1468 x 35mm|
|System Power||Panel Qty||Controller Type||Minimum Array Area|
|280 Watts||2||Outback FM80||2.37 m2|
|420 Watts||3||Outback FM80||3.56 m2|
|560 Watts||4||Outback FM80||4.74 m2|
|700 Watts||5||Outback FM80||5.93 m2|
|840 Watts||6||Outback FM80||7.12 m2|
|1.12 kW||8||Outback FM80||9.49 m2|
|1.40 kW||10||Outback FM80||11.86 m2|
|1.68 kW||12||Outback FM80||14.23 m2|
Note that the AKT-140-M solar panel can be connected together in either a series, parallel or a combination of both to give a higher output voltage or charging current from the array than a single panel.
For example, 4 off AKT-140-M solar panels panels connected in series would give maximum operating voltage 70 volts (4 x 17.5) at 8.0 amps ( Vmp x Imp = 70 x 8.0 = 560W ). Likewise, 4 off AKT-140-M solar panels connected together in parallel would give 17.5 volts at 32.0 amps ( Vmp x Imp = 17.5 x 32.0 = 560W ). It is always better for circuit design and installation to connect together high wattage solar panels such as this AKT-140-M to give a higher voltage and lower current configuration.
Solar charge controllers allow the configuration of solar arrays with high open circuit voltages (Voc) and may thousands of watts. The Outback FLEXmax FM80 is a powerful charge controller capable of operating at its full maximum current rating of 80 Amps. The 80A charge controller uses Maximum Power Point Tracking (MPPT) technology with adjustable current limiting to extend the life of the connected batteries.
This 80A Charge Controller can work with sealed, gel and lead-acid battery banks. The controller supports a wide range of nominal battery voltages from 12V to 60VDC and has the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built-in, backlit 80 character display shows the current status and logged system performance data for the last 128 days at the touch of a button.
