Enphase And Panasonic Partner On AC Solar Panels

Panasonic Enphase AC solar panel

A partnership between Enphase Energy and Panasonic will see Enphase’s IQ 7X Micro microinverter combined with Panasonic HIT solar modules.

An AC solar panel is one that has a microinverter integrated on the back of the module. The use of microinverters does away with the need for a central solar inverter; offering redundancy, panel level monitoring and other benefits.

The Panasonic/Enphase announcement is light on details as to when the AC solar panel will be released (and just generally), but says the IQ 7X Micro is already compatible with Panasonic N Series HIT panels. Panasonic claims N Series panels are among the most efficient on the market, have a temperature coefficient1 of -0.258% /⁰C and will keep at least 90.76% of their initial power output after 25 years of use.

Integrating the IQ 7X with the panels will provide lower install times and additional savings on logistics and overhead costs.

“This partnership with Enphase Energy will enable us to combine our products and expertise to offer a new solar solution that can help our customers meet their renewable energy needs,” said Panasonic’s Mukesh Sethi.

Of course, Enphase is also rather chuffed with the partnership.

“We are excited to work with Panasonic on this new high-performance AC module program,” said Enphase Energy Chief Commercial Officer David Ranhoff. “Panasonic is a global brand that homeowners know and respect.”

Enphase recently launched the IQ 7, its seventh generation microinverter. The company states the IQ 7 Micro series produces 4% more power, is 19% lighter and 17% smaller than the IQ 6 series. Optimized for 60-cell, 72-cell (IQ 7+ Micro) and 96-cell (IQ 7X Micro) modules, the latter can handle 320-460+ watt solar panels says Enphase2 and has a 97.5% CEC Efficiency.

Here’s a closer look at the IQ 7X Micro.

According to the preliminary datasheet (PDF), the unit is 212 mm x 175 mm x 30.2 mm (without bracket) and weights 1.08kg.

It’s good to see Enphase kicking more goals as it has been experiencing some challenges – you can learn more about those and a little more about the IQ 7 series in this post from Ronald.

Other solar panel manufacturers to team up with Enphase on AC solar modules include JinkoSolar (Eagle AC) and LG (NeON 2 ACe).

Footnotes

  1. As the temperature of a solar panel increases above standard testing conditions (25C), the power output starts dropping below its nameplate rating. The lower a temperature coefficient rating is, the better.
  2. Enphase/Panasonic press release says “up to 400W”

    My understanding is that the Jinko Eagle panels, are the ones that include the Maxim Integrated Optimisation.

    Now, on the premise that the Jinko panels are including the Maxim Integrated Optimisation, at

    is


    You can’t monitor panels with Maxim, and I’m told you can’t use Maxim and solarEdge or Tigo. The “boost-buck” function of each optimizer would fight against each other and be counter-productve. If individual panel monitoring is the most important thing, I would use solarEdge. Solaredge is still a very good system. If shading is really bad, (as in some panels shaded most of the day) you may even consider using Enphase microinverters.

    raising the question of whether, if the Maxim Integrated Optimisation of the Jinko panels, will not work with SolarEdge DC Optimisers, will it work with Enphase microinverters?

    Also, as the Maxim optimisation apparently has a bad reputation dfor disrupting television reception, how does this combination of the Jinko Eagle panels with the Enphase microinverters, affect television reception?

  2. With the existing Enphase microinverters, a problem that had apparently been said to exist, is that, in having the inverters up on the roof, with the panels, efficiency is said to deterorate in warm weather, when the microinverters get hot (hotter than a single inverter would be, if mounted in a shaded location), and, similarly, the failure rate is supposed to be inconveniently high (compared to shaded single inverters), both leading to decreased system performance, due to the use of the microinverters on the roof.

    Also, the potential for overloading, to the extent of being able to have up to 33% overloading; thence, having up to 6.66kW of panels running a 5kW single inverter on a single phase electricity grid connection, is supposed to be diminished by the use of microinverters.

    Could these points, and, the issues (invalid or valid), raised in my previous post on this web page, please be clarified?

    Thank you in anticipation.
