Independent Technical Solar Consultancy and System Audits

100% Unbiased Advice.  17+ Years Industry Experience | 8,000+ Systems Worked On during this time.

Navigating the New Zealand solar market can be overwhelming. Whether you are drowning in conflicting quotes, wondering why your current system isn't delivering expected savings, or dealing with equipment faults, Steve from Hitek provides completely independent, expert analysis.

Because we do not push specific retail sales agendas during consults, our advice is purely focused on real-world engineering, regulatory compliance, and maximizing your long-term financial ROI (genuine real-world savings not just in theory with over inflated numbers given by so many).

🔍 How Can We Help You? (Select Your Scenario)

1. Pre-Purchase Quote Analysis, Quote Comparisons & Pitfall Protection

• Who it’s for: Anyone who has obtained 1, 2, 3, 4, 5, 6 or more quotes from solar companies and feeling unsure about which quote is best and wanting all the quotes professionally compared and reviewed.  In some cases one quote may stand out above the rest and in other cases sometimes not even a single quote may even meet the full requirements correctly, so we can then assist to help you to get your existing quotes re-quoted so that actually meet your needs correctly.

• What we do: We perform a complete Needs Analysis factoring in your phase connection (1, 2, or 3 phase), NZ-specific network lines rules, EV/PHEV charging plans, hot water setups, pool/spa heat pumps, and peak tariff times.

• The ROI: Spotting hidden red flags, standby power losses, and poor round-trip battery efficiency upfront typically saves our clients $2,000 to $7,000+ in avoided mistakes and over-spec’d equipment.

2. New Installation & Post-Commissioning Audits

• Who it’s for: Systems currently being installed or completed within the last 24 months.

• What we do: We review installation specs and system setups to ensure work was completed correctly. In many cases, we identify configuration or commissioning errors within 4–16 weeks of installation that original installers missed.

3. Underperforming Systems & High Power Bills

• Who it’s for: Existing solar or battery owners whose power bills are still unexpectedly high.

• What we do: Remote diagnostic checks to identify string faults, system faults or losses, inverter configuration errors, panel isolation/ground faults, inverter fault errors, battery fault errors or phase imbalance issues.

4. System Upgrades, Aging Hardware & Off-Grid Troubleshooting

• Who it’s for: Owners of older setups (3 to 15+ years old), grid-tie, hybrid, off-grid, RV, motorhome, or marine setups.

• What we do: We assess aging battery banks (AGM, GEL, Lead Acid, Lead Carbon LFP, NMC, Sodium-Ion), run battery health diagnostics, and explore repair vs. replacement options to try and avoid unnecessary full-system teardowns.
