HardKorr 170W Fixed Solar Panel
$199.00
HardKorr
Lightweight and powerful solar panels built to last.
Our high-quality 170w fixed solar panels will fit neatly on the roof of a 4wd, caravan, camper trailer or boat. Being only 17mm high, they are aerodynamic and weigh about 30% less than regular 30mm high fixed panels.
The A-grade monocrystalline solar cells are protected by 3.2mm tempered low-iron glass, which is optically clear and provides high impact resistance against hail, stones and accidental knocks. The all-black frame, cells and substrate look incredible on any vehicle.
The panels come with a 0.8m cable terminated with industry-standard MC4 connectors, which are waterproof and will not come apart once connected. We have also developed matching mounting brackets to make it easy to fix your panels in place.
With a 10 year warranty backed by Hardkorr’s reputation for quality, you can’t go wrong with these solar panels. Start powering your adventure from the sun for free today!

Know before you buy
Before you buy a battery set-up
A second battery runs your fridge, lights and charging without touching the starting battery. Modern vehicles and lithium batteries change how that system should be built.
- Smart alternators
Many late-model vehicles have smart alternators that vary their voltage. A simple isolator doesn't charge a second battery well from these, so a DC-DC charger is recommended (Redarc).
- Where lithium can go
Lithium batteries must not go in the engine bay: the heat is too much (Redarc, Enerdrive). They go in the cabin, tub or canopy.
- Charge it correctly
Lithium needs a charger with a lithium profile, and most can't be charged below 0 C unless the battery is heated. Don't mix battery brands or sizes in one system (Redarc).
- Sizing solar
Work out how many watt-hours you use a day and divide by 5 to 6 sun hours to size your panels. A panel laid flat can lose up to 38% of its output (Enerdrive).
Common questions
Do I need a DC-DC charger?
If your vehicle has a smart alternator, yes: isolators charge poorly from them. A DC-DC charger also gives the second battery the right charging profile, including for lithium (Redarc).
Can a lithium battery go under the bonnet?
No. Battery makers say lithium batteries can't handle engine bay heat and must not be installed there (Redarc, Enerdrive).
Lithium or AGM?
Lithium needs a charger with a lithium profile, a location out of the engine bay and, below 0 C, a heated battery to charge. Compare usable capacity and weight on each battery's specifications, and follow its maker's mounting guidance.
How much solar do I need for a fridge?
Add up your daily use in watt-hours, then divide by 5 to 6 sun hours (Redarc). Allow extra if the panel will lie flat or sit in shade.
Can I run my fridge off the starting battery?
You can, but you risk a flat battery and no start. A second battery with a DC-DC charger keeps the starting battery for the engine.
