Bright Sunday is a Swedish solar-as-a-service company founded in 2016, majority-owned by Stockholm-based Niam’s Infra Fund. It builds and operates zero-upfront solar PPAs for commercial and industrial customers across Sweden, Spain and Portugal, where it has passed the €10 million investment mark.
Bright Sunday designs, finances, installs and operates rooftop and ground-mount solar for commercial and industrial customers, selling the electricity back under flat-rate power-purchase agreements with no upfront investment from the client. Founded in Sweden in 2016, the company was acquired by Niam’s infrastructure fund — whose backers include the European Investment Fund — to finance a pan-European roll-out, and today runs a portfolio of roughly 65 projects and some 20 MW of installed capacity serving 54 customers across Sweden, Spain and Portugal.
Portugal is one of its three operating markets: per the Luso-Swedish Chamber of Commerce, Bright Sunday has passed the €10 million mark in Portuguese solar investments, deploying its zero-capex model with Portuguese industrial and commercial off-takers.
Bright Sunday is part of a distinct corridor vein: Nordic infrastructure capital funding distributed-energy assets on Portuguese roofs. Alongside developers like Eurowind Energy and investors like Verdane-backed Cleanwatts, it shows Nordic money treating Portuguese C&I solar as a scalable asset class rather than a one-off project.
