Trine is a Swedish crowdlending platform, based in Gothenburg and lending since 2015. Private investors lend to companies that sell or run solar power and electric vehicles in emerging markets in Africa, Asia and Latin America, such as rooftop solar for businesses and electric two-wheelers. By 25 October 2026, 15,318 investors had put in €119.2 million, much of it repayments lent again, and €97.6 million had been paid back.
You choose loans yourself or use auto-invest. Loans are in euros or US dollars; the borrowers earn in local currencies, so currency falls become their problem first and can turn into credit risk for you. Standard loans run about five years with quarterly repayments; profit-share loans, which pay out on the electricity produced, can run up to 15 years. The average term of new loans was 74 months in 2025 and 68 months in early 2026. In August 2026 only one loan was open to new investment.
Trine publishes what investors actually earned: across all loans issued from 2015 to 2026, the weighted average return was 5.85% a year after credit losses and before tax (25 October 2026). It is well below the rates offered on loans, because of losses in earlier years; the average rate on all loans is 7.43%. By year of issue, returns range from 3.06% (2016) and 3.51% (2022) to 7.67% (2024), 8.26% (2025) and 9.16% (2026); the recent years are still being repaid and are partly projections. Loans issued since 2021 average 6.5%. New loans offer about 8% to 9%; a loan open in August 2026 projected 9.30%, give or take 2%. The figures leave out your own currency conversion costs and count restructured loans as performing. Some long-term investors report returns close to zero.
Investors have lost real money. Unsecured lending for household solar kits went badly in 2019 to 2021: credit losses peaked at 9.1% of the portfolio in 2020 and reached €7.7 million by the end of 2024. In December 2025 two more borrowers were written off, for €2.84 million, which is 4.2% of the €68 million lent from 2021 to March 2026 (calculated from the platform's own figures); nothing had been recovered by March 2026. The platform's live figures show €8.19 million defaulted out of €118.8 million fully funded since the start, 6.89% (25 October 2026).
The yearly default rate Trine reports under the EU crowdfunding rules was 8.99% for 2023 (8 of 89 loans), and 0% for 2024 and 2025. It counts a loan as defaulted when the borrower is unlikely to pay in full without enforcing security, or is more than 90 days late. The 0% sits beside the 2025 write-offs and 28 loans to one borrower, ecoligo, that were put on new repayment plans and are counted as performing. Six borrowers took about 68% of lending from 2021 to 2026.
Security differs from loan to loan: some have a company guarantee or a pledge over the solar equipment or the payments customers owe, and some are unsecured. Certain loans carry investment protection from Sida, the Swedish development agency, and Trine guarantees each new investor's first investment up to €100. There is no buyback and no provision fund. Each loan gets an internal risk grade, and a borrower in trouble is first put on a new repayment plan before it is declared in default. Trine's review of its older losses shows about 43% recovered; on the two loans written off in December 2025, nothing has come back yet. In plain words: you depend mainly on small energy companies in developing countries paying, and enforcing security there is slow.
Trine AB (company 559003-1463, Gothenburg, registered in February 2015) is supervised by Sweden's financial regulator, Finansinspektionen. It has been an authorised payment institution since 2019 and a licensed EU crowdfunding service provider since 11 December 2023. It is a small company: in 2025 it had revenue of SEK 13.5 million, a loss of SEK 3.2 million and equity of SEK 11.9 million. No regulator action against it was found.
Trine charges no fee for card payments; SEPA transfers cost what your bank charges. Payments through Trustly from Swedish, Norwegian and Finnish bank accounts carry a 0.25% exchange fee when kronor are changed into euros.
You cannot sell early. There is no secondary market, so your money comes back only as each borrower repays, over five years or more, and longer if a loan is restructured. Repayments land in your Trine wallet, where you can reinvest them or withdraw them to your bank. If Trine failed, your claims on the borrowers would remain and investor cash is held in a separate bank account, but no back-up company to run the loans is named.
Return: Very Low — investors earned 5.85% a year after losses across all loans since 2015. Risk: Very High (higher means more risk) — €2.84 million, 4.2% of lending since 2021, was written off in December 2025 with nothing recovered yet, after an earlier wave of losses, which on its own gives High; we set it one step higher because many loans have been restructured and a few borrowers hold most of the money. Risk-return: Very Low — a modest return for a very high level of risk, with money locked in for years.
License / Regulation: Trine AB (org. no. 559003-1463, Sweden) is supervised by Finansinspektionen, the Swedish financial regulator: an authorised payment institution since 2019 and a crowdfunding service provider under Regulation (EU) 2020/1503 since 11 December 2023. Investments are not covered by any state deposit guarantee.
Yes. Trine AB is supervised by Sweden's financial regulator, Finansinspektionen, as a payment institution (since 2019) and as an EU crowdfunding service provider (since 11 December 2023). Regulation does not protect you from losses on the loans.
Trine itself, as a licensed payment institution: investor money is kept in a separate bank account, apart from the company's own funds. The bank is not named, and no deposit guarantee applies.
Trine's own help pages do not state a minimum; independent reviews report €25 per loan. Auto-invest can reinvest repayments from €1.
Across all loans since 2015, investors earned 5.85% a year after losses (October 2026). Losses reached €7.7 million by the end of 2024, and a further €2.84 million was written off in December 2025. The yearly default rate was 0% for 2024 and 2025, but restructured loans are not counted.
It depends on the loan: some have a company guarantee or a pledge over equipment or receivables, some are unsecured, and certain loans have investment protection from Sida, the Swedish development agency. There is no buyback or provision fund, and recovery in the borrowers' countries is slow.
No. There is no secondary market; your money comes back only as borrowers repay, usually over about five years and up to 15 years for profit-share loans. Repayments in your wallet can be withdrawn.
No fee for card payments, and SEPA transfers cost what your bank charges. Trustly payments from Swedish, Norwegian or Finnish accounts carry a 0.25% exchange fee. Your own currency conversion costs are not included in the published returns.
If a borrower fails, Trine first tries a new repayment plan, then enforces any security or guarantee; recoveries have been slow and partial. If Trine failed, your claims on the borrowers would remain and investor cash is segregated, but no back-up servicer is named.
Losses on household solar loans in 2019 to 2021 and the write-offs in December 2025 pull the average down: loans issued in 2022 returned 3.51%, while loans from 2024 onwards show 7.67% to 9.16%, partly projected.
