Solar Panels & Kits

How do I calculate how much solar energy I need?

The size of your solar system depends on the appliances you plan to run. Use our LUX Solar Calculator for an estimate of the solar wattage and battery size required.

Tip: Locations with less sunlight or winter use typically need higher capacity, while sunnier areas or summer-only use may need less.

What are the dimensions of the solar panels in your kits?

Product dimensions and specifications are listed on our Solar Panel Product Page — each panel includes detailed measurements and data.

Should I choose fixed or flexible panels?

We recommend fixed panels whenever possible for their affordability and durability. For marine or curved-surface applications, our Sunman eArc® flexible panels are ideal. These are certified to the same standards as framed panels and approved by the Clean Energy Council of Australia for building-mounted installations.

Where are your solar products made?

Our solar products are sourced globally:

  • Most panels are made in China, where advanced specialization ensures quality and efficiency.
  • We also offer REC Alpha panels, designed in Norway and manufactured in Singapore and Norway.

Should I buy two small panels or one large panel?

Choose whichever fits your roof or installation space best — both options perform efficiently if wattage is equivalent.

Installation & Wiring

Do your solar kits include installation instructions?

Yes — every kit comes with a detailed LUX Solar DIY Installation Manual. If you’re in Auckland, we also offer installation starting from $699.99.

For assistance, contact us by email at info@luxsolar.co.nz or phone 027 458 9674.

Do I wire my solar panels in parallel or series?

We recommend series wiring for most setups since modern “half-cut” panels reduce shading issues common in series connections. Use our AnyKit Builder to calculate the most efficient wiring option. It includes all required components (pre-wired if desired) and a free wiring manual.

Note: If parallel wiring is preferred, you’ll need to purchase a parallel connection kit.

Should I install my panels in parallel or series?

We recommend connecting panels in series for most systems. However, for high-wattage installations, parallel wiring may better match your MPPT controller’s requirements.

What electrical safety precautions should I take?

For safety and best performance, we recommend using a competent installer. Refer to WorkSafe New Zealand for official guidance on DIY versus professional installations.

“When a PV system operates entirely at ELV, the work on that system must comply with AS/NZS 3000 and AS/NZS 5033. However, this is not PEW and does not require certification or inspection.”
“Extra-low voltage (ELV) means any voltage normally not exceeding 50V AC or 120V ripple-free DC.”

Battery & Protection Systems

Can I use my existing battery with your solar kits?

Yes — but confirm compatibility first. Use our Solar Calculator to ensure your battery capacity matches your solar setup.

Why do your kits include circuit breakers and fuses?

These components are legally required in many systems and help prevent overheating, short circuits, and fire risks. Circuit breakers protect both your equipment and cabling.

Off-Grid Solar

What does “off-grid solar” mean?

Off-grid solar systems are completely independent from the national electricity grid. They generate and store their own power through solar panels and batteries, giving you reliable energy anywhere — from remote cabins to RVs and boats.

Can I run my whole house on off-grid solar?

Yes — it’s possible with a correctly sized system. You’ll need enough solar panels and battery capacity to power your home, even at night or during cloudy days. Use our LUX Solar Calculator to estimate your full off-grid requirements.

What maintenance do off-grid systems need?

Minimal maintenance. Clean your panels occasionally to remove dust or debris, and visually inspect cables and mounts a few times a year. Lithium batteries are maintenance-free — no topping up or venting required.

What is the lifespan of solar panels and batteries?

High-quality solar panels last around 25–30 years, maintaining about 80% of original output. Lithium batteries typically last 10–15 years or 3,000–6,000 cycles, depending on usage.

Can I monitor my off-grid system remotely?

Yes — most of our charge controllers and inverters include Bluetooth or Wi-Fi monitoring. You can track live performance, solar generation, and battery status via smartphone apps.

What type of batteries are best for off-grid solar?

Lithium Iron Phosphate (LiFePO₄) batteries are ideal. They’re lightweight, safe, fast-charging, and long-lasting. Lead-acid batteries can be cheaper upfront but have shorter lifespans and need more maintenance.

How much does an off-grid solar system cost in New Zealand?

Costs vary by usage and system size. Small setups for cabins or RVs start from around $1,000–$3,000, while full off-grid home systems can range from $10,000–$25,000+. Try our LUX Solar AnyKit tool to build a system that fits your needs and budget.

Warranty & Support

What warranty does LUX Solar offer?

Warranty coverage depends on the components in each kit. Refer to individual product pages for full details:

  • Fixed solar panels: 10-year mechanical warranty (stationary)
  • Marine & RV installations: 5-year warranty
  • Power output: 25-year warranty (80% rated output)

Can I visit your showroom in Auckland?

Our office in Panmure, Auckland serves as a packing depot, as we operate primarily online. We’ve created helpful tools like the LUX Solar AnyKit to help you design your perfect system — shipped pre-wired with a custom installation manual.

If you’d like to visit in person, please call 027 458 9674 to arrange a time.
