Bulk redistribution is not permitted. --- # Sunwealth Review 2026: Solar Impact Fund Terms, Track Record and the DOE Guarantee Sunwealth's website gives its Solar Impact Fund notes a 3-year term on one page and a 6-year term on another, and neither page states a current rate. The rate, security and priority of the notes are only in private offering documents. The company says it has paid investors with no defaults for over a decade but publishes no payment or loss history by vehicle, and the $289.7 million DOE loan guarantee it closed in January 2025 has an unconfirmed current status. AltStreet score: 29.2 (D), scored November 14, 2026. Method: https://altstreet.investments/platforms | Field | Value | | --- | --- | | Platform | Sunwealth | | What it is | Solar Finance Company: Private Notes, Funds and Tax Equity for Accredited and Institutional Investors | | Asset class | Community and commercial solar projects (debt and tax equity) | | Website | sunwealth.com | | Review first published | November 14, 2026 | | Last updated | November 14, 2026 | | AltStreet relationship | None: no affiliate, sponsorship or partnership | ## The short version Sunwealth Power, Inc. is a Cambridge, Massachusetts company that co-develops, finances and owns small solar projects (schools, nonprofits, affordable housing, community solar) and sells three things to accredited and institutional investors: notes in the Solar Impact Fund, notes in the Solar Justice Fund, and Solar Tax Equity in project pools. Nothing can be bought online; every route is to email investors@sunwealth.com and receive private documents. Two live pages disagree on the Solar Impact Fund's term (3 years on /how-we-invest, 6 years on /featured-investments), and neither states a current rate; the site publishes no rate, minimum, fee, security or priority for any product. Sunwealth says it has delivered targeted returns 'for over 10 years with no defaults', but no payment or loss history by vehicle is public. The Form D notices AltStreet reviewed report $55.9 million of cumulative securities sales across 34 offerings from 2017 to 2025. Nine single-investor vehicles account for 40.4% of that, and Needham Bank's filings show it is the 99% tax equity investor in three pools, two of which filed no Form D. The Solar Justice Fund's only notice, in 2023, reported $0 sold at filing. Sunwealth expected its $289.7 million DOE loan guarantee, closed in January 2025, to cover about 30% of its project financing needs over four years; its current status is unconfirmed. AltStreet located no enforcement action or lawsuit naming Sunwealth. - **3 or 6 years** Solar Impact Fund term on sunwealth.com/how-we-invest ('3-Year Term') and /featured-investments ('Term: 6 years'), captured November 14, 2026; neither page gives a current rate. - **$55.9M** Cumulative securities sales reported on the 34 Form D offerings AltStreet reviewed, 2017 to 2025 (AltStreet arithmetic on the notices at sec.gov); nine single-investor vehicles account for 40.4%. - **$0** Sold at filing on the Solar Justice Fund's only Form D (April 2023), the fund the site markets today; no later amendment was located. - **$289.7M** DOE loan guarantee to Sunwealth Holdco 18 LLC (Project Polo), closed January 16, 2025; Sunwealth expected it to cover about 30% of its project financing needs over four years. Its current status is unconfirmed. Data note: Form D figures are cumulative sales reported on each notice, not current balances. Company figures (capital invested, projects, megawatts, 'no defaults') are Sunwealth's own and are not audited or independently verified; no Sunwealth financial statement is public. ## Key figures | Figure | What it is | Context | | --- | --- | --- | | 3 or 6 years | A note buyer cannot learn from Sunwealth's own site how long the money is tied up or what it pays. | Solar Impact Fund term on two live sunwealth.com pages. Neither page states a current rate, minimum, security or priority; those are only in the private offering documents. | | $289.7M | DOE loan guarantee to Sunwealth Holdco 18 LLC, closed January 16, 2025. | Sunwealth expected it to cover about 30% of its project financing needs over four years; current status unconfirmed. | | $55.9M | Cumulative securities sales reported on Sunwealth's 34 Form D offerings, 2017 to 2025. | Nine single-investor vehicles account for 40.4%; the Solar Justice Fund's only notice reported $0 at filing. | | 0 | Enforcement actions or lawsuits naming a Sunwealth entity located (November 14, 2026). | Counterparty in the Sunworks and iSun contractor bankruptcies. | ## Verdict Sunwealth is an established community solar financier with real institutional partners, but its own pages give the Solar Impact Fund two different terms and no rate, and the rate, security and priority of its notes are only in private documents. Its no-default record is a company claim without a public payment history by vehicle, and the DOE guarantee closed in January 2025 has an unconfirmed current status. **Best for** - Accredited impact investors, ideally through an adviser, who will obtain and read the offering documents and audited statements before investing. **Look elsewhere if** - You need published terms or audited results to decide. - You may need the money within the note term. - You are not accredited. **Strengths** - Eleven years of operations, 838 projects and institutional lenders and tax equity investors. - Impact focus documented in annual reports since 2018. - No enforcement action or lawsuit located. **Limitations** - No public rates, fees, minimums, ranking or financial statements. - Conflicting Solar Impact Fund terms (3 and 6 years) on live pages; latest listed quarterly report Q3 2023. - Partial Form D record; the Solar Justice Fund's only notice reported $0 at filing. - DOE guarantee's current status unconfirmed. ## Who it fits | Investor | Fit | Why | | --- | --- | --- | | Accredited impact investors who will read and negotiate the private documents | neutral | | | Investors who need published terms, audited results or liquidity | poor-fit | | | Non-accredited investors | poor-fit | | ## Questions **Is Sunwealth legit?** Sunwealth Power, Inc. has financed solar projects since 2014 with lenders including Reinvestment Fund, Calvert Impact, RSF Social Finance and Goldman Sachs, closed a DOE loan guarantee in January 2025, and AltStreet located no enforcement action or lawsuit against it. What an investor cannot do is check its terms or results: no rate, fee, offering document or audited financial statement is public, and its 'no defaults' record is the company's own claim. **What does the Solar Impact Fund pay?** Sunwealth does not publish a rate. The site promises 'Competitive fixed-income returns for accredited investors' with quarterly interest; third-party write-ups cite roughly 6% (2017) and 5% to the Sierra Club Foundation (2019). The term is 3 years on one live page and 6 years on another. **What is the minimum investment?** Not stated on the site. Write-ups from 2019 and 2022 give $25,000; Form D minimums range from $2,500 to $100,000. Only accredited investors can invest. **Can I get my money out early?** No redemption or transfer terms are published; the notes run 3 to 7 years and tax equity 5.5 years. **What is the DOE loan?** A guarantee of up to $289.7 million from DOE's Loan Programs Office for Sunwealth Holdco 18 LLC's Project Polo, announced as closed on January 16, 2025 after a conditional commitment in November 2024; federal award records show actions on both dates. Sunwealth expected it to cover about 30% of its project financing needs over four years. Its current status is unconfirmed: Heatmap News reported in January 2026 that it was a likely candidate among loans DOE eliminated or revised, and on November 14, 2026 DOE's loan portfolio page did not list it. AltStreet could not verify whether Sunwealth drew on the loan or whether the guarantee remains in force. **How much has Sunwealth raised?** The 34 Form D offerings AltStreet reviewed report $55.9 million of cumulative securities sales from 2017 to 2025. Sunwealth separately reports $273 million invested in projects through 2025; that is a different measure, and the public record does not show how the two connect. ## Update history **November 14, 2026: DOE guarantee record: GAO listing and federal award actions added** The DOE section now cites GAO-25-106631, which lists Sunwealth Project Polo among five projects that received conditional commitments after September 2024, and USAspending award DELP0000171, which shows a new award on November 25, 2024 and a non-financial action on January 16, 2025, with no amount drawn shown. DOE did not name Project Polo in its January 2026 announcement of revised or eliminated loans; whether Sunwealth drew on the loan or the guarantee remains in force could not be verified. Score unchanged. **November 14, 2026: Needham Bank's carrying values for Project Pools 20 and 26 added** NB Bancorp's 10-Q for September 30, 2023 carries its Project Pool 20 investment at about $1.9 million (from $2.3 million at December 31, 2022) and its Project Pool 26 investment at about $3.4 million (from $5 million, which included an $800,000 refundable advance), without explaining the changes, and places the $2.5 million Holdco 8 loan in its construction and industrial loan portfolio. Score unchanged. **November 14, 2026: Published after owner pass 1: leads with the Solar Impact Fund term conflict, Form D totals kept as their own measure, DOE status stated as unconfirmed, payment record corrected** The review now leads with the finding a note buyer can check: sunwealth.com gives the Solar Impact Fund a 3-year term on one page and 6 years on another, with no rate on either. The comparison of $55.9 million in Form D sales with the $273 million Sunwealth reports as invested is removed from the summary, meta description and verdict, since the two are different measures and the record does not connect them; the single-investor share is described as concentration, with bank tax equity attributed only to the pools Needham Bank's filings name. The DOE guarantee is described as closed in January 2025 with an unconfirmed current status and Sunwealth's own 30% financing expectation. The payment record cites the Q3 2022 report (31 quarters) and the current 'over 10 years with no defaults' claim; the Investor Hub's latest listed quarterly report is Q3 2023. The Solar Justice Fund's 2023 notice is described as $0 sold at filing, with the annual-amendment rule; accredited-only eligibility is attributed to Sunwealth's terms and filings. Team size is stated against the archived snapshot and kept out of the verdict. ## Evidence appendix Platform website captured November 14, 2026.
