English (United States)<h2>location-specific design of your photovoltaic system</h2>
Easily plan & calculate photo and twilight times for the perfect shot!
SolCalc - Solar Calculator wins the thumbnail scan: every screenshot carries a large white headline plus one plain sentence ("Plan a whole month of light ahead"), while PV Calculator's opening frame packs five phone mockups behind 6pt sub-copy and its fourth screenshot runs uncaptioned. PV Calculator's actual selling point, annual savings and payback time, appears only in the description, never in an image. The money outcome and a legible caption on every frame are the two fixes with the most upside.

Only the first 4 screenshots from each side are sent to the AI. These are what users see in App Store and Google Play search results, so they carry most of the conversion weight.

App B
Value Proposition
B leadsPV Calculator's hero promises "Plan your path to a sustainable energy future", but payback time and annual savings never appear in any screenshot.
SolCalc - Solar Calculator states the payoff on three frames: "Get the right time — every time", "Know when to capture the perfect moment".
Clarity
B leadsRoof panel placement with module dimensions reads clearly, but the yield and coverage frame carries no caption and its axis labels are tiny.
Each frame names one function in plain words: "Visualize", "Forecast", with sun-path map and dated sunrise/golden-hour rows visible beneath.
Emotional Hook
TiedSolar-panel photography behind every frame plus "sustainable energy future" sets a tone, but no homeowner or moment of relief is depicted.
"Know when to capture the perfect moment" is desire-shaped copy, yet the night-sky purple backdrop shows no photographer or shot.
Trust Signals
TiedThe four badges on PV Calculator's first frame name capabilities ("Maximum yield", "Global availability"), not credibility; no counts, sources, or certifications.
SolCalc - Solar Calculator shows no testimonials, download counts, or badges; only an in-app PRO chip appears in the location bar.
Reviews of PV Calculator repeatedly praise the breadth of the modelling, from GPS location through array orientation to payback, and several reviewers highlight how much the free, ad-free version already covers. The recurring friction is onboarding: reviewers ask for more explanation of fields, and a separate group asks for off-peak or economy-7 tariff options for battery charging, while a smaller set disputes the estimates. SolCalc - Solar Calculator draws praise for being simple and straightforward, but the short sample also contains comments about being hard to get started with and about how much sits behind the pro upgrade.

MediumPV Calculator stakes out the energy and money reading of "solar calculator": TMY irradiance data, hourly yield, battery sizing, "annual savings and payback time". SolCalc - Solar Calculator stakes out the sun-position reading: sunrise, golden hour, twilight and shadow length "for the perfect shot!". The two listings share a query but not a job, so the search result page mixes two intents and whichever listing signals its intent fastest in title and short description wins the tap.

Gap
PV Calculator leads with system design economics ("location-specific design of your photovoltaic system", savings and payback), while SolCalc - Solar Calculator leads with light timing for photography ("photo and twilight times for the perfect shot"), so the same query resolves to two unrelated jobs.
Opportunity
Because SolCalc - Solar Calculator explicitly claims the photography reading of "solar", PV Calculator can claim the energy-investment reading outright and absorb every searcher whose real question is how many panels and what payback.
Risk
The title "PV Calculator" uses an abbreviation the query does not contain, and the description opens on a mission statement about renewable energy potential before reaching savings and payback, so a searcher scanning for cost answers may not connect the listing to their question within the first impression.
Strategic advantage
Hourly resolution on a typical meteorological year, individual load profiles and roof-area panel placement are inputs a rule-of-thumb calculator cannot offer, which matters to the buyer comparing a real installer proposal rather than idly estimating.
Missed opportunity
Neither listing speaks to the quote-checking moment: the person holding an installer's offer who wants an independent second opinion on the promised yield and payback. That is a high-intent, high-trust position neither app currently claims.

SolCalc - Solar Calculator
Slight lead
SolCalc - Solar Calculator carries the stronger listing for solar calculator, even though PV Calculator currently sits one position higher at rank 2. That rank looks borrowed rather than earned: PV Calculator leads on review sentiment and depth of modelling, but neither its title nor its short description contains the words a searcher actually typed.
Why it wins
SolCalc - Solar Calculator states the query in the title and follows it with a plain-language promise about planning light and twilight times, so intent registers in the first line read. Its screenshots also carry one legible headline per frame, while PV Calculator's opening image stacks five mockups behind small sub-copy and leaves its strongest claim, annual savings and payback, to the description alone.
Biggest opportunity
PV Calculator owns the energy and money reading of solar calculator that SolCalc - Solar Calculator never contests, and that position is currently invisible in the two lines a searcher scans first.
Next priority
Test a short description that opens with solar calculator and the financial outcome together, for example "Solar calculator: size panels & battery, see savings and payback time" at 69 characters. Putting the payback number on the first screenshot as well attacks the same gap in both places the tap gets decided, and reviewers already name that modelling depth as the reason to stay.
