Panasonic is a household name and one of the largest consumer electronic manufactures. Ever since they’d entered to solar market, they provided the competitive pricing, warranties, and performance.

When it comes to solar performance, efficiency matters. An efficient solar panel means how well it collects sunlight and generate it into electricity. Although various panels may be the same size in kW, such a 325 W panel, depending on the manufacture, how efficient the panel maybe will vary. The efficiency rating is how to determine a panels energy collecting potential. The efficiency rating for Panasonic solar panels is one of the high rated ranging between 18.5% to 20.3%.  For this reason, Panasonic is a premium brand for solar pv. The majority of other brands typically range between 14% to 18% efficiency.

Temperature Performance (Coefficient)

The temperature coefficient is a value that indicates how well a solar panel performs under dramatic weather conditions during cold winters and hot summers. For every degree exceeding 25° C/77° F, a solar panel’s production will be reduced by its temperature coefficient.

As an example, consider a panel with a temperature coefficient of -0.3%/°C. If the panel’s temperature increases by one degree from 25° C/77° F to 26° C/79° F, its production decreases by 0.29%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 2.9%.

Panasonic HIT® Technology

Panasonic’s technology has designed high performance panels that have a high efficiency rating and low temperature coefficient.  Their HIT® product line is the industry’s best selling residential solar module.

  • Higher module efficiency power output.
  • 40mm frame to increase durability and strength
  • Water drainage system that channels rain and snow melt reducing stains and soiling that may affect performance.
  • Technology that reduces annual degradation to 0.26% as compared to 0.70% in conventional solar panels.
  • 25-year warranty that covers performance and workmanship.

Panasonic Warranty

A manufacturer’s quality in materials and performance dictates the warranty terms that they guarantee. It’s a promise in good faith that they will replace their equipment if it fails due manufacturing defects or under performance. The majority of manufacturers offer a 10-year warranty on their panels. Panasonic on the other hand, offers a 25-year warranty which guarantees up 86.2% power output after 25 years (depending on the panel model).

Being that Panasonic is one the leading electronic brands, they offer some of the most competitively priced panels in the market for residential solar. With affordability, quality, and high performance they lead the pack. Add their 25 year warranty, and going solar with Panasonic becomes a no brainer.
