How to Use This Calculator

Answer all 10 questions honestly

Each question targets a specific barrier or enabler for solar adoption. Answer based on your current situation — not what you hope will be true. The scenarios (First-time homeowner, Established homeowner, Renter, Senior near retirement) pre-fill typical patterns for each profile, so you can see what gaps each buyer type typically faces.

Read the action items for every "No" answer

Every "No" comes with a specific action item — not just a flag. The calculator tells you exactly what to do: improve your credit score, replace your roof first, check your state's solar access law for HOA restrictions, or explore community solar if you rent. Many barriers are solvable in 3–12 months.

Use the score to time your purchase

A score of 8–10 means act now — you have everything aligned for a successful solar investment. A score of 5–7 means do the prep work first (typically 3–12 months). A score of 0–4 means solar may not be right for you yet — and rushing it risks a poor financial outcome.

The Scoring System

Score = Number of "Yes" answers (0–10) 0–4: NOT READY — address barriers before investing 5–7: ALMOST READY — specific gaps to close (3–12 months) 8–10: READY TO BUY — get at least 3 competing quotes

The 10 questions were selected based on the most common reasons solar investments underperform or fail: short holding periods without sale premium planning, low utility bills making economics thin, shading problems not addressed, roof condition requiring rework, and ITC unavailability reducing the incentive. Addressing even 2–3 "No" items can move a buyer from "Almost Ready" to "Ready."

Example

Lisa — First-time homeowner, 3 years in, high electric bill, planning to stay 8+ years

Lisa bought her first home 3 years ago. She pays $220/month in electricity. Her south-facing roof is 8 years old with no shading issues. She has a 710 credit score, $8,000 in savings, and her HOA allows solar. She understands the 8-year payback timeline and expects to stay in the home 10+ years.

FAQ

Renters have several options: (1) Community solar — subscribe to a portion of a shared solar farm in your area. You receive credits on your utility bill with no installation required. Available in many states. (2) Green power programs — many utilities offer renewable energy options on your existing bill. (3) Talk to your landlord — some landlords are open to installing solar in exchange for a rent credit or property value increase. (4) Solar-powered apartments — increasingly available in urban areas. The National Renewable Energy Lab's "Low-Income Community Solar" programs specifically target renters.
Yes — always replace a failing roof before installing solar. Removing and reinstalling solar panels for a roof replacement costs $1,500–$3,000 in labor plus potential damage risk. The good news: you can often negotiate a combined project. Many solar installers have roofing partnerships, and some roofing materials (like Tesla Solar Roof or GAF solar shingles) integrate the two projects. The ITC may apply to the roof replacement if the new roof is specifically for solar — consult a tax advisor.
Requirements vary by lender: 650–679: Mosaic, GoodLeap, and some credit unions — expect higher rates (8–12% APR). 680–719: Most solar lenders — rates of 5–8% APR. 720+: Best rates — 3–6% APR from specialized solar lenders. If your score is below 650, a home equity loan or HELOC typically has easier qualification (based on equity, not just credit score) and lower interest rates. A $0-down solar loan at 8% APR for 25 years on a $25,000 system is about $193/month — often close to or below current utility bill savings.
In most states, no — "solar access laws" or "solar rights laws" prevent HOAs from outright banning solar. States with strong protections include California, Florida, Texas, Colorado, Arizona, and 25+ others. However, HOAs can still regulate: panel placement (may require panels not visible from the street), aesthetics (panel color, flush-mounting requirements), and approval processes (you may need to submit a design for review). Get your HOA's approval in writing before signing an installer contract — some HOA approval processes take 30–60 days.
At $60/month ($720/yr), solar economics are challenging. A modest 4 kW system costing $12,400 (after ITC: $8,680) would need 12+ years to pay back through savings alone — and that assumes 100% of production offsets your bill. Before investing in solar, consider: (1) An LED lighting retrofit ($200–$500, often saves $15–$30/month). (2) A smart thermostat ($150, saves $100–$150/year). (3) If you're planning to add an EV or electric appliances soon, your future bill will be higher — solar may make more sense in 1–2 years.
