About Solar Math Pro
Who runs this
Solar Math Pro is a Bedrocka Tools property, operated by Bedrocka Ventures LLC — an AI-native holding company based in Chicago. This site lives at solarmathpro.com and covers one thing in depth: the math of residential solar economics. That includes state incentive stacking (DSIRE tracks 3,000+ active state and utility programs), lease vs. buy 25-year NPV comparison, battery storage ROI and break-even under IRC §48E and time-of-use rate arbitrage, and financing path comparison across cash, solar loan, HELOC, PPA, and lease.
Its sister site, soloopfinance.com, is the broader self-employment finance hub — Solo 401(k) vs SEP-IRA, LLC vs S-Corp, QBI deduction strategy. Solar Math Pro goes deep on the solar-specific economics axis for homeowners who have decided to evaluate solar and need the math without the installer sales layer. Same doctrine, different depth. Both sites are source-cited, reviewed quarterly, and corrected immediately when the underlying data or regulatory landscape changes.
Why solar math needs its own site after §25D
IRC §25D — the 30% federal residential solar tax credit — expired December 31, 2025. The One Big Beautiful Bill Act (OBBBA) did not extend it. The solar economics problem doesn't disappear when the federal credit ends; it gets harder. Now the math is entirely state- and utility-specific: a homeowner in Massachusetts can stack a 15% state income tax credit, a 100% property tax exemption, and an SREC market worth $200–$300/MWh. A homeowner in Texas has no state income tax credit and no SREC market, but has strong net metering in some utility territories.
Per Autumn Proudlove, DSIRE Program Manager, the DSIRE database tracks 3,000+ active state and utility solar incentive programs across all 50 states — the complexity is real, and it has only grown as states have expanded their own programs in response to the federal credit expiration. Per Andrew Sendy, SolarReviews Founder (SolarReviews, 2024): “Most homeowners overlook state-level incentives that can be worth more than the old federal credit in high-incentive states like Massachusetts, New York, and California.”
Most solar calculators online are built by installers, lead aggregators (EnergySage CPL model), or lenders with a commission on the financing path you choose. Per Vikram Aggarwal, EnergySage CEO (EnergySage Solar Marketplace Report 2024): “Solar shoppers who get multiple quotes save 20% on average” — the same information asymmetry applies to the math layer, not just the installer quotes. This site addresses both: open formulas, primary sources, and no commission on any output.

The human behind it
Byron Malone is the founder and editor. He has been a solo operator since 2018 — running consulting engagements, then building Bedrocka Ventures and its portfolio companies as a single-member LLC operator. That hands-on operator experience is the editorial foundation for this site: Byron has modeled the same decisions this site covers — whether a lease or a cash purchase pencils out on a 25-year NPV basis, what state incentive stacking looks like in Illinois, and how battery storage economics change under time-of-use rate structures.
The solar landscape shifted materially in 2025. The §25D expiration removes the single largest variable from the federal incentive math but leaves the state-level picture more complex than ever. Most existing solar calculators were built around the §25D credit as a first line in the model. Byron built this site because the post-§25D version of that math — state-incentive-first, financing-path-aware, 25-year NPV anchored — wasn't available from a source without a commission on the answer.
Bedrocka Tools is built natively on AI automation with documented human review at every step. Byron leads editorial direction on solar economics content. For YMYL-Finance content covering state-specific tax credit eligibility, IRC §48E battery storage credit rules, and utility rate modeling, Bedrocka Tools commits to review by qualified subject-matter experts before publication as prescriptive guidance.
These calculators estimate solar savings based on publicly available data (DSIRE, NREL PVWatts, EIA utility rates). They do not constitute installation advice, financial advice, or legal advice on tax credit eligibility. Individual results depend on your specific system, utility territory, and state tax situation. Verify incentive eligibility with your state revenue agency and a licensed installer.
How we make money (and how we don't)
We make money two ways. Display ads, labeled “Advertisement” on every page, served through programmatic ad networks (Mediavine Journey, home-improvement niche). Editorial affiliate partnerships, labeled “Editorial pick · Affiliate partner”, where we may earn a commission if you sign up with a partner we recommend — at no cost to you.
We never let revenue influence calculator logic or recommendations. The math is the math regardless of whether a sponsor wants it to look different. If a partner ever asks us to tune a calculator's output to favor their product, we end the partnership. See our affiliate disclosure for the full list of partners and FTC-compliant terms.
Why open source
Every calculator on this site is published as TypeScript on GitHub under MIT license. Every formula traces to a primary source — DSIRE state incentive database, NREL PVWatts, EIA Form EIA-861, IRC §48E, or IRS Form 5695. Every page has a real human reviewer with public accountability. Solar decisions involve real dollars and real system contracts. We built Bedrocka Tools so readers can audit the math themselves instead of trusting a black box built by an installer with a CPL deal.
