The Secret to Generating Reliable Solar Power in Your Home

Jan 22, 2020

The big promise of going solar is that you’ll enjoy decades of lower utility bills and a smaller carbon footprint. However, these financial and environmental benefits only exist when installing a solar installation that can withstand the test of time. As such, it pays to invest in high quality panels installed by knowledgeable experts who can properly test and configure your system.

But with no moving parts, even subpar panels can last decades with minimal maintenance. This explains why manufacturers can confidently offer 20 to 25 years of warranty protection.

As a homeowner, you should still invest in the best solar panels you can afford. Doing so is necessary for optimal utility bill savings and carbon offsets. But if long-term durability is important, the real focus should be on the solar inverter – which is responsible for turning the direct current (DC) power from your panels into alternating current (AC) electricity for your home’s appliances.

Let’s explore why.

The Relationship between Solar Inverters and System Reliability

Over the many years that your solar installation is expected to perform, your inverter is the most likely component that’ll need replacing since it:

  • Has more sensitive components and wiring
  • Manages all your panels’ higher voltage power
  • Often comes with moving parts (like cooling fans)

Due to natural wear and tear, most solar inverters only come with 10 to 12 years of warranty protection. And whereas a faulty panel won’t bring your system down, a broken inverter means that your entire installation will stop working. 

But with the right technology, it’s possible to avoid both problems so that if an issue does occur with your inverter:

  • Clean solar electricity continues to flow from your installation
  • Repairs are fully covered for the next 25 years – guaranteed

The Enphase Energy Approach to Solar Inverters

Unlike centralized power stations, solar is a distributed technology that allows homeowners to create their own clean electricity. And with enough solar installations connected to the utility network, there is no single point of failure within the wider energy grid. At Enphase Energy, we’ve adopted this same strategy when developing our solar inverters. Instead of using centralized “string” inverters that manage your entire solar installation’s electricity flow, we’ve designed state-of-the-art microinverters that attach to each panel in your system. This means that even if one microinverter goes down, the rest of your installation continues generating clean power – with zero interruption.

In other words, there is no single point of failure in your solar installation.

Better still, microinverters have very low failure rates. That’s because the heat exposure and power loads for any single microinverter are much lower than with a centralized string inverter. This means less overall wear and tear – and by extension – longer lifespans. But at Enphase Energy, we don’t stop there.

To ensure that our microinverters can withstand the complex demands of modern solar applications, they undergo 1+ million hours of rigorous stress testing and training. This is why we can confidently offer 25 years of ironclad warranty protection – which is more than double the industry average for inverter technologies.

Equally important, Enphase Energy’s microinverters:

  • Come with modular, panel-level control designed to optimize your solar savings. Even if one of your panels is shaded, dirty, or broken – your system can continue generating clean power.
  • Are safer than conventional inverter technologies since there is no high-voltage DC running through the entire installation. The DC to AC conversion happens at the panel level – not at the system level.
