Frequently asked questions

FAQs About Sungold Solar Panels

Which RV solar panels are best for my roof (rigid vs flexible)?

Rigid panels cost less per watt and last longer on flat roofs; flexible panels suit curved roofs and low profile. Match voltage to your MPPT controller and check roof load. See our flexible panel range or rigid modules for specs.

Will my RV solar charge the batteries while driving?

Alternator charging and solar can run together if your BMS or DC-DC setup allows it. Use a proper isolator or DC-DC charger to avoid over-current from the alternator.

How many watts do I need for weekend RV use?

Typical weekend loads (lights, fridge, devices) often land in 200–400W of solar with adequate battery storage. Size from your daily Wh budget and sun hours at your camps.

Are Sunray panels suitable for salt spray on boats?

Use ETFE-fronted modules and sealed junction boxes. Rinse salt regularly and mount with isolation from standing water in bilges. Contact us for a marine mounting plan.

Can I walk on deck-mounted flexible panels?

Only if the specific series is rated for foot traffic. Most lightweight flex panels are not designed to be walked on—mount in low-traffic areas.

What inverter size do I need for off-grid cabin?

Add peak loads (kettle, tools) plus startup surge for motors. A pure sine inverter matched to battery voltage (12/24/48V) is recommended for sensitive electronics.

How do I size battery bank vs solar array?

Target 1–3 days autonomy without sun. Solar should recharge the daily cycle within typical sun hours for your latitude—use a simple energy audit (Wh/day).

Is balcony solar allowed in my building?

Rules vary by country and HOA. Many plug-in balcony kits limit output for safety. Check local grid codes and landlord requirements before installation.

What is the typical output of a small balcony kit?

Micro systems often range 400–800W peak; real yield depends on orientation, shading, and season. Use an MPPT controller sized to the array.
