A Nordic first: LONGi EcoLife brings solar independence to a Swedish home

LONGi had the privilege of installing the EcoLife modules on the private home of someone who must know what’s good in solar: Jing-Wei Sheng, CEO of Aprilice, one of Sweden’s leading solar distributors and installers. A real expert in the field of PV.

60 EcoLife panels of 500 Watt each were installed on Jing-Wei Sheng's roofs, creating a powerful 30 kWp system.

What does that mean in practice? In Stockholm conditions, a 30 kWp EcoLife system can produce around 27–28.5 MWh per year, enough to cover most or all of a typical household’s annual electricity use.

The choice of EcoLife makes a difference. Thanks to back contact technology, the panels deliver more power on the same roof area compared to conventional modules. And with their uniform dark design, they blend seamlessly into Nordic rooftops without compromising aesthetics.

Other features that stand out for homeowners include:

• Cold climate performance, with strong low-light response and tested resistance to snow and wind loads.
• Long warranties of up to 30 years, covering both product and performance, ensuring reliable output for decades.
• Safety and sustainability certifications, giving peace of mind that the technology is robust and responsibly made.

For this Swedish family, the installation means producing all the electricity they need directly from their own roof, gaining independence from rising energy costs, and reducing their carbon footprint at the same time. For other homeowners, it’s a glimpse into what’s possible when the roof becomes more than just shelter but a source of power.

In Sweden’s rising energy market, EcoLife cuts costs and builds independence

In Sweden, where a typical four-person household consumes around 4,000 kilowatt-hours of electricity per year, EcoLife back contact modules show clear advantages over conventional panels. A roof fitted with twelve EcoLife modules (about 6.1 kilowatts) can generate roughly 5,500 kilowatt-hours annually, compared to around 4,900 kilowatt-hours from the same number of standard modules. Without a battery, this translates into covering nearly half of a household’s annual demand directly from the roof, cutting the variable part of the electricity bill by around 50 percent at prevailing tariffs. When paired with a home battery, self-consumption can rise to 70–80 percent, allowing families to reduce their grid purchases dramatically and save between 5,000 and 7,000 Swedish kronor per year. The higher efficiency of back contact technology ensures that even with limited roof space, households can capture more of their own power needs, gaining both financial relief and greater independence from rising energy prices.
