Smart Fill

Fill face puts every panel that fits: 1,055 modules, 611.9 kWp, on a job sold at 500 kWp. Getting down to 500 means deleting 195 panels by hand and redoing strings and energy.

Smart Fill opens next to fill face. Type the kWp you sold, or fill to the sanctioned load or a budget. The roof switches to the sunlight view so you can see which faces get less sun before you preview.

Faces are ranked by how much sun they get after shade. A and B stay full; most of D (behind the lift room) and all of E (next to the neighbouring mill) come off. The panel says what stopped it: whole strings land at 498.8 kWp.

Apply removes 195 panels at once and saves a new version. Strings, inverters, energy and price recompute in order; when the simulation is busy the panel says so and how long to expect.

All numbers are back: 498.8 kWp, 4 inverters, 783.6 MWh a year. Capacity fell 18.5% but energy only 17.3%, because the panels that went were the shaded ones. Each face gets one line saying why.

One click makes 400, 500 and 600 kWp versions of the same roof, each filled on the sunniest faces. Energy, price, savings and payback sit side by side so the sales engineer can offer a choice instead of one number.

Parekh Textiles opens one link: three sizes with price, savings and payback, then a page that explains in plain words why panels go where they go and why the strip by the neighbouring mill stays empty.

A 700 kWp target is more than the roof holds and more than the 650 kW sanctioned load. Smart Fill names the limit and gives ways forward with their sizes, instead of a bare error.

On one selected face, 8 kWp is less than a single string of 20. Smart Fill stops and offers three valid choices with the design total for each, instead of rounding without telling you.

If the sunlight map fails, Smart Fill still reaches the target on geometry alone and says so. Without the map it keeps the strip next to the mill, which shows what the sunlight ranking adds: 10.5 MWh a year here.

On a weaving shed with east and west slopes plus a flat office roof, Smart Fill ranks faces by expected kWh per kWp and fills each direction in whole strings. It shows the cost of the other choice: 0.4 MWh a year for more even east and west.

The same panel on a 24-face warehouse in Sacramento. The faces behind the office block and around the HVAC units empty first. DC:AC drops from 1.49, which needs a warning, to 1.19.

For Rivergate, the three sizes are checked against the 1,000 kW AC interconnection approval. The largest is shown with its warning and clipping, so the owner sees why 1.2 MW is the recommendation.

For a home in Ahmedabad, fill to the sanctioned load instead of a kWp. Smart Fill keeps 8 of 15 positions, away from the neighbour's shade and the staircase room, and says that one sunny spot is empty only because of the 5 kW cap.
