About

SolarMath is a fully local home solar-panel payback and sizing calculator toolkit — estimates only, never a quote, a financing offer, a tax/legal opinion, or a substitute for a licensed solar installer. solar_payback_calculator takes system cost, expected annual production (kWh), your electricity rate, and any tax-credit percentage, and computes a simple payback period (net cost after the credit / year-1 savings), a year-by-year cumulative-savings projection out to 25 years (or a custom length) that compounds a documented electricity-rate-inflation assumption (default 3%/year, overridable) as real compound growth, and an inflation-adjusted payback point — the year cumulative savings actually cross net cost, usually a bit sooner than the simple figure. system_size_estimator takes your average monthly usage and estimates the required system size and panel count using the standard solar-industry back-of-envelope method (daily usage / (peak sun hours x system-loss derate)), with overridable panel-wattage and system-loss assumptions. Every response carries a disclaimer field. Keyless; fully local; zero upstream calls; nothing stored.

Sources: Computed locally / hand-curated, using published general emission-factor and energy assumptions (electricity-rate inflation, panel wattage, solar-industry system-loss/derate conventions comparable to NREL PVWatts defaults); fully local, zero upstream calls

Estimates only — not a quote or a substitute for a licensed solar installer

SolarMath is a home solar-panel payback and sizing calculator for learning and general planning. It is never a quote, a financing offer, a tax or legal opinion, or a substitute for a site-specific proposal from a licensed solar installer. Actual production, electricity rates, available incentives, equipment choice, and system losses all vary by location, roof, and utility. Every tool response carries a disclaimer field restating this.

What SolarMath is for

The math that comes up before you talk to an installer or sign anything — how long a system takes to pay for itself, what 25 years of rising electricity rates is actually worth in savings, and roughly how many panels a given monthly usage would need — answered with real, transparent computation, with no upstream calls and nothing about the user stored.

What it does

solar_payback_calculator takes a system cost, expected annual production (kWh), your electricity rate, and any available tax credit percentage, and computes a simple payback period (net cost after the credit divided by year-1 savings), a 25-year (or custom-length) year-by-year cumulative-savings projection that compounds an electricity-rate-inflation assumption (default 3%/year, overridable), and an inflation-adjusted payback point — the year cumulative savings actually cross net cost, normally a bit sooner than the simple figure since later years' savings are worth more as rates rise. system_size_estimator takes your average monthly usage and estimates the required system size and panel count, using the standard solar-industry back-of-envelope method (daily usage / (peak sun hours x system-loss derate)), with overridable panel-wattage and system-loss assumptions.

What it is not

Not an installer, not a financing quote, and not a substitute for a site assessment. It does not know your roof's orientation, shading, local permitting costs, your utility's actual rate structure (tiered or time-of-use rates, net-metering rules), or panel degradation over time — all of which affect real-world numbers. solar_payback_calculator and system_size_estimator both do genuine arithmetic from the numbers you give them, but neither is a substitute for a real proposal. Get a written quote and site assessment from a licensed solar installer before making a purchase decision.

SolarMath — Privacy Policy

Effective 28 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What SolarMath is. SolarMath is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a home solar-panel payback and sizing calculator toolkit: a payback-period calculator, a 25-year cumulative-savings projection, and a rough system-sizing estimator. SolarMath is estimates only and is never a quote, a financing offer, a tax/legal opinion, or a substitute for a licensed solar installer. You interact with your assistant; the assistant sends us only the arguments needed for that one calculation.

What we receive. The arguments of each tool call — for example a system cost, annual production figure, electricity rate, tax-credit percentage, monthly usage, sun hours, or panel wattage — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered locally and nothing is stored. SolarMath makes zero upstream/network calls: every response is arithmetic computed directly from the arguments given plus a small set of documented, overridable general assumptions. No request is forwarded to any third party, and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. We do not know your address, your roof, your utility account, or anything else about your home beyond the bare numbers in a single request. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — every calculation runs locally on our server with no external dependency. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. SolarMath is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Terms of service

SolarMath — Terms of Service

Effective 28 September 2026. These terms govern use of the SolarMath connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

  1. The Service. SolarMath returns solar-panel payback, savings-projection, and system-sizing figures computed from the arguments given plus documented, overridable general assumptions (electricity-rate inflation, panel wattage, system-loss derate). It is accessed through an AI assistant or directly over MCP or HTTP.
  2. Estimates only — not a quote, a financing offer, or a substitute for a licensed solar installer. SolarMath is not a solar installer, not a financing provider, and not a tax or legal advisor. Nothing the Service returns is a quote, a binding offer, or a guarantee of actual production, savings, or payback for any real installation. Actual results depend on your roof, shading, orientation, equipment, local permitting, your utility's actual rate structure, and available incentives — all of which vary and are not accounted for beyond the numbers you supply. Never rely on the Service in place of a written quote and site assessment from a licensed solar installer, or advice from a qualified tax professional regarding any credit or incentive.
  3. No liability for financial decisions. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any financial loss, missed savings, or other loss arising from or related to any solar purchase, financing, or installation decision made with or without reference to the Service. Our total liability, to the extent liability cannot be excluded, is limited to US $100.
  4. Figures change and vary. Electricity-rate inflation, panel wattage, system-loss, and similar figures reflect commonly-cited general assumptions that you can override; actual electricity rates, incentives, and system performance vary by location, time, and utility and are not tracked or updated by the Service in real time.
  5. Acceptable use. Automated use within the published rate limits is welcome.
  6. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
  7. Data. Our Privacy Policy describes what we process. In short: your query is answered by direct computation, and nothing is stored.
  8. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
  9. Governing law. California law; venue in San Mateo County, California.
  10. Contact. Unify Dynamics LLC · agent@connectorbay.com · https://connectorbay.com/solarmath
