We're sick of solar myths circulating so we're here to set the record straight. When it comes to installing solar panels on your roof, some things simply aren't true. Here are the top 5 solar myths — debunked.
Myth 1: Solar Panels Only Work in Full Sun
The truth: Solar panels generate electricity from daylight, not just direct sunlight. Even on overcast days, panels produce a significant portion of their rated output. New Zealand's climate means even the cloudiest days still deliver useful solar generation.
Myth 2: Solar Panels Are Too Expensive
The truth: Solar system costs have fallen by over 90% since 2010. Combined with government STCs (rebates), $0 upfront payment plans, and rapidly rising electricity prices, solar has never been more affordable or more valuable. Most homeowners see full payback in 3–5 years.
Myth 3: My Roof Isn't Suitable for Solar
The truth: While a north-facing roof with minimal shading is ideal, east and west-facing roofs still perform well. Modern solar inverters and panel configurations can work around shading issues. A free site assessment will quickly determine what's possible for your property.
Myth 4: Solar Panels Require Constant Maintenance
The truth: Solar panels are among the lowest-maintenance home technologies available. With no moving parts and a design life of 25+ years, minimal maintenance is required. Rain keeps panels reasonably clean; an annual inspection and occasional active cleaning is typically all that's needed.
Myth 5: I Should Wait — Solar Technology Will Get Better
The truth: While solar technology continues to improve, the cost improvements are slowing as the technology matures. Every year you wait is a year of energy savings lost. The payback period starts from the day your system is installed — waiting costs you money.
