Central Coast Solar Panels
When you’re off-grid or constantly on the move, solar panels can make all the difference. At Central Coast Batteries in Long Jetty, we supply the Central Coast with portable solar panels that are perfect for charging deep-cycle batteries in caravans, boats, 4WDs and camping setups. Lightweight, foldable and easy to connect, our panels help you stay powered up without needing a mains connection. Whether you're heading away for a weekend or living off the grid, a reliable solar setup means less stress and more freedom.
We’ll help you choose a panel that suits your system and power needs. For personalised advice or product support, give us a call on (02) 4308 9094.
Simple Power, Anywhere You Go
Portable solar panels are one of the most practical tools for anyone who relies on battery power outdoors. They’re ideal for topping up your batteries during the day, reducing generator use, and avoiding the risk of running out of power overnight. Most models pair easily with standard regulators or battery management systems, and some include built-in controllers for plug-and-play use. Whether you're using them with a camping fridge, lighting setup or full off-grid rig, we’ll help you get the right size, output and portability for your needs.
With solar, it’s not just about going green, it’s about having peace of mind when you're away from power.
What size solar panel do I need to charge a 12V battery?
The right size depends on how much energy you’re using and how quickly you want to recharge. For light use—like powering LED lights and small devices—a 100W panel may be enough. For camping fridges, inverters or multiple accessories, 160W to 200W or more is often recommended. Keep in mind that sunlight hours, panel efficiency and battery capacity also affect performance. It's a good idea to match your panel to your average daily power use.
Can solar panels overcharge a battery?
Yes, but only if they’re used without a regulator or charge controller. A charge controller regulates the voltage and current coming from the panel to ensure the battery doesn’t get too much power. Most modern setups include built-in protection, especially in folding or plug-and-play kits. Always use a charge controller for safe, long-term use of your battery with solar panels.
Are portable solar panels as efficient as rooftop systems?
Yes, but their output is reduced. Solar panels still generate power in overcast conditions, though typically at 10–25% of their usual capacity. The exact output depends on panel quality and cloud density. While you may not fully recharge a battery on a cloudy day, good panels paired with a regulated setup can still contribute to your energy needs.
