ZonHub, formerly ZonnepanelenDelen, is a Dutch crowdfunding platform for renewable energy, run from Amsterdam by Zonnepanelendelen B.V. It launched in 2012. Investors lend to the companies behind solar parks, solar rooftops and, more and more, battery projects. Through its crowdfunding bonds it has raised €97.6 million for 206 projects (30 June 2026); counting its other products, the home page shows more than €160 million and about 13,000 active investors (August 2026).
You choose projects yourself and buy bonds from the project company, usually from €25 (€250 for the shorter ZPD PRO bonds). There are three products. Bonds (obligaties) pay a fixed rate for 5 to 15 years. ZonneDelen run about 15 years and pay a variable amount that depends on how much power the panels produce and on power prices, so in a bad year they can pay nothing. ZPD PRO bonds pay a fixed rate over shorter terms. Offers in 2026 run from 1 year 5 months to 15 years.
ZonHub publishes what investors actually received. In 2025 it paid €2.35 million of interest, 4.47% of the money that was out on loan at the start of the year; in 2024 the figure was 4.69%. Before 2023 it was between 1.2% and 2.8% a year, because older projects carry low or variable rates. Figures as of 30 June 2026. These are interest payments only: they do not subtract capital that may still be lost in defaulted projects. New offers promise more: fixed rates from 4% to 12% a year, most often 8% (August 2026). In total, investors have received €9.18 million of interest and €16.96 million of capital back.
Very little money has been written off so far, but defaults are rising. Since 2012 investors have lost €27,500 of capital, about 0.03% of the €97.6 million invested (30 June 2026, calculated from the platform's own figures). That figure is low partly because few projects have ended: only 16 of 206 have been fully repaid and one partly ended. Under the EU crowdfunding rules ZonHub publishes a yearly default rate (more than 90 days late on a material amount, or unlikely to pay), counted by number of projects: 2.80% in 2023 (4 of 143), 4.52% in 2024 (7 of 155) and 4.97% in 2025 (8 of 161), an average of 4.1%. Payment changes approved by investors are not counted as late, and no list of late or defaulted projects is published. Investors report several named projects that have paid nothing for years, including a working solar park whose payments are blocked by its bank and a rooftop project unpaid since 2021 (August 2026). Losses could end up higher once these cases are settled.
Little. The bonds are usually junior: the project's bank is paid first, and the bank's loan conditions can stop payments to you even when the project earns money. Some projects give a pledge on the installations or on the project company's shares; this varies per project, and ZonHub publishes no loan-to-value limit or independent valuation policy. There is no buyback, reserve fund or insurance on top. A foundation, Stichting Zonnedelers, represents bondholders, and on some newer deals project income runs through an account ZonHub monitors. No recovery figure for failed projects is published. In plain words: you lend to one energy project behind its bank, and if it struggles the bank is paid first and your interest can stop for years.
Zonnepanelendelen B.V. (Amsterdam, chamber of commerce no. 56170319) runs the platform. The Dutch regulator AFM has licensed it as an investment firm since 31 May 2018 and as a European crowdfunding service provider since 31 January 2024 (licence no. 32000024), which lets it serve investors in 11 other EU countries. Both licences were active in 2026, with no regulator action found. Bonds issued from 1 January 2024 are kept in a legally protected custody register that stays outside ZonHub's assets if it fails; older bonds are not. The company does not publish audited accounts. Public review score 3.4 out of 5 (47 reviews, August 2026); the main complaint is late or missing payments.
The only investor charge in the platform's help pages is for selling early: 2% of the sale price, at least €10 and at most €500, taken from the seller. On a €25 holding that minimum is 40%. Companies raising money pay ZonHub; the amounts are not published.
Usually you wait until the bond ends, which can be 15 years. There is no trading market. For bonds, ZonHub can put your holding on a sales list, but you must find the buyer yourself; the sale then runs by private deed and needs the issuer's approval. For ZonneDelen, a buyer asks ZonHub for your contact details and you agree the deal directly. No figure on how often holdings are sold is published, and one investor reports waiting months for the money after a sale.
Return: Very Low — investors received 4.47% in interest in 2025, well below the 8% most new offers promise. Risk: Low (higher means more risk) — realised losses are tiny at about 0.03%, but we rate it one step worse because the yearly default rate rose from 2.80% to 4.97% between 2023 and 2025, investors report projects unpaid for years, and the bonds rank behind banks. Risk-return: Low — a low realised return for a low but rising level of risk.
License / Regulation: Zonnepanelendelen B.V. is licensed by the Dutch Authority for the Financial Markets (AFM) as a European crowdfunding service provider (licence no. 32000024, granted 31 January 2024, with custody of assets and passports to 11 EU countries) and as an investment firm (since 31 May 2018) for offers above €5 million. Both licences were active in 2026; no regulator action was found. Investments are not covered by a deposit guarantee or investor compensation scheme.

Cash waiting in your account sits in an e-wallet at Mangopay, a payment institution, outside ZonHub's own accounts. Once invested, you hold bonds issued by the project company. Bonds issued from 1 January 2024 are kept in a protected custody register; older bonds are not.
€25 for bonds and ZonneDelen, €250 for ZPD PRO bonds. Individual projects may set a higher minimum.
Investors received 4.47% in interest in 2025 and 4.69% in 2024, measured on the capital out on loan at the start of each year; new offers promise 4% to 12%, most often 8%. Realised capital losses are €27,500, about 0.03% of all money invested (30 June 2026), but the yearly default rate rose to 4.97% of projects in 2025, and only 17 of 206 projects have ended.
Little. The bonds usually rank behind the project's bank, whose loan conditions can stop your payments. Some projects give a pledge on the installations or the project company's shares, but there is no buyback, reserve fund or insurance, and no recovery figure is published. A foundation represents bondholders.
Only if you find a buyer yourself. ZonHub can list bonds for sale, but there is no trading market; the sale needs a private deed and the issuer's approval, and costs 2% (at least €10, at most €500). Otherwise you wait until the end, up to 15 years.
The platform's help pages list one investor fee: 2% of the price when you sell early, at least €10 and at most €500. Companies raising money pay ZonHub; the amounts are not published.
If ZonHub fails, bonds issued from 1 January 2024 stay outside its assets in a protected custody register; older bonds do not have that protection. Cash sits at Mangopay. If a project fails, its bank is paid first and you may recover little.
ZonneDelen pay a variable amount that depends on how much power the panels produce and on power prices. In a weak year that can be zero without the project being in default. Fixed-rate bonds and ZPD PRO bonds pay a set rate instead.
