Why Some Homeowners Aren’t Getting the Solar Results They Expected – and How to Avoid It
Solar power is a smart investment for many Kiwi households. When done right, it can reduce your power bills, give you more independence from the grid, and protect you from rising energy prices. But we often hear stories of people feeling disappointed with the results of their solar system.
If you’re thinking about installing solar in the Wellington or Kāpiti region, here are some common pitfalls — and how choosing the right installer can help you avoid them.
- The System Wasn’t Designed for Their Home
Every home is different. A villa in Thorndon won’t use power the same way as a modern build in Paraparaumu. Roof angles, shading, and daily usage patterns all affect performance. If the design doesn’t reflect your household’s needs, you may end up with a system that doesn’t deliver the savings you expected.
Solution: Work with a solar professional who looks closely at your power bills and daily routines before designing your system.
- Lower Quality Products or Install Work
Not all panels and inverters are created equal. While cheaper options can look attractive at first, they may underperform or fail earlier than expected. A rushed installation can also
lead to inefficiencies or faults later on.
Solution: Choose a solar company with proven experience and trusted suppliers. Look for accreditation and long-term warranties so you know your system will last.
- Unrealistic Expectations About Savings
It’s common for people to expect their power bill to vanish completely once solar is installed. In reality, the amount you save depends on your household usage, system size, and your retailer’s buy-back rates.
Solution: Ask your installer for clear, personalised forecasts. A good provider will show you realistic numbers, not just sales pitches.
- Not Knowing How to Use the System
Even the best technology won’t pay off if you don’t know how to use it. Many homeowners don’t realise that running big appliances during the day — when panels are producing — makes a big difference to savings.
Solution: Work with an installer who takes time to show you how to monitor your system and adjust your habits to get the most from it.
- Lack of Ongoing Support
Some companies disappear once the job is done, leaving homeowners without guidance or help when issues come up. Without support, even small problems can erode long-term value.
Solution: Choose a local company with a solid reputation for after-care. Ongoing service and support are key to making solar a lasting investment.
