What Vote Solar does
Mission
Vote Solar's mission is to realize a 100% clean energy future through a solutions-driven, people-first approach.
As stated on its FY2025 Form 990.
Program
On its FY2025 return the organization reported a significant change in how it conducts a program.
Overall staffing was reduced in 2025 with a 30% reduction occurring in August 2025. This has lead to some consolidation/adjustment in programmatic services, but the overall programs remain in place.
Its own explanation, from Schedule O of that return (Part III, line 3).
Vote Solar accelerates the transition to a 100% clean energy future by advancing policies and programs that expand access to clean solar energy and support a reliable, affordable and modern electric grid. We advocate for a more dynamic and resilient grid by promoting the integration of solar with energy storage and other innovative technologies, including community power networkssometimes called virtual power plantsthat aggregate local resources to bolster energy supply and improve grid stability in the face of extreme weather and surging demand. Additionally, we are advancing fair frameworks for managing new large-scale demand from data centers and electrification to ensure these new customers support clean energy growth without shifting financial burdens onto everyday ratepayers. By intervening in complex regulatory proceedings like Integrated Resource Planning and rate cases, we hold monopoly utilities accountable, realigning their financial incentives with the public interest through Performance-Based Ratemaking. Simultaneously, we work to dismantle market barriers by championing interconnection and permitting reforms that lower costs and prevent delays, ensuring that the…

The program described on its FY2025 Form 990. Program spending in total: $7,502,224.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $11M to $16M (+44%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 5%. Grants only. Government contracts and fees sit inside program revenue.
93% of Vote Solar’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 9 funders to 30 funders, grant income rose $3.3M → $13M.
16 of 67 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 34% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Vote Solar’s funders (the co-funder graph). Top 30 of 67 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Vote Solar has a broad base — no single funder exceeds 15% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
66% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Vote Solar.
Largest funder’s share by year: 2017 24% · 2018 28% · 2019 27% · 2020 23% · 2021 42% · 2022 22% · 2023 24% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
53% of Vote Solar's funders are still giving 3 years after their first grant; 70% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
71% of Vote Solar's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $19M arriving through sponsors registered in 12 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
Vote Solar's funding base is broadening — from 9 funders to 30 as grant income climbed.
