Inside PitchSun
The real app. No mock-ups.
Every screen below is PitchSun as your team will use it — the Graphite workspace theme, real designs, real numbers.
01 / 07 · Roof layout
Draw the roof. Fill it to the bill.
Trace the terrace on satellite, drop the mumty, tanks and trees, then let PitchSun fill it to what the family actually uses.
- Sized from the electricity bill, not the roof
- Winter row spacing worked out for the latitude
- Price, saving and payback move as you move panels
One tap · 18 panels placed
02 / 07 · 3D & shadows
Show the roof before it exists.
Every structure is built in 3D — the elevated frame over the terrace, panels on the mumty, the inverter on its wall — with the real sun moving over it.
- Tables, legs and steel counted per structure
- Play the day in winter, summer or equinox
- Drop the view straight into the proposal
03 / 07 · Factories
A whole factory on one screen.
Aravali Precision Castings: a metal-sheet machine shop and two RCC blocks, traced from the satellite — one design, one bill of materials, one proposal.
- Gable shed filled on both faces, 1 m clear at the edges
- Low-rise rows on RCC, walkways every 10 columns
- Six 110 kW inverters planned for you
04 / 07 · Strings & SLD
The engineering, done before they ask.
Strings, cables and protection are sized the moment the panels go down, and the single line diagram draws itself.
- Voc checked at the coldest morning — 1,013 V ≤ 1,100 V
- DC and AC cables sized with voltage drop
- IEC-symbol SLD, earthing and lightning arrester
05 / 07 · Quote
The number they'll say yes to.
Type the bill, pick the DISCOM — the quote fills in with your prices, the PM Surya Ghar subsidy and GST at 70:30, live.
- DISCOM slabs reversed to find units used
- ₹78,000 subsidy applied where eligible
- Bill today against bill with solar, side by side
06 / 07 · Proposal
Their roof, on their phone.
One tap sends the proposal on WhatsApp, as a link or a PDF. The family scrolls their own roof in 3D, the subsidy and the payback — in their own language.
- English, Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada or Bengali
- They turn the 3D roof themselves
- You see every time it's opened

Questions installers ask us.
Does it handle commercial and industrial projects?
Yes. Metal-sheet and gable roofs, ground-mount arrays and RCC blocks in one design, up to 20 inverters, C&I tariffs with time-of-day rates, and CAPEX vs RESCO financials with IRR, NPV and LCOE.
Can my customer see the 3D design?
Yes. The proposal link has a 3D view of their own roof — they can turn it around and play the sun through the day on their phone.
Can I design from my phone?
Yes. The designer, quick quote and proposal all work on a phone. A laptop gives you more room for large factory roofs.
How is the subsidy calculated?
PitchSun applies the PM Surya Ghar central financial assistance — ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 — with higher amounts for special-category states and UTs.
Can I use my own panel and inverter prices?
Yes. Build your price list from the equipment library; every quote uses your products and prices, with the 70:30 GST split applied.
