      How the planner works

      Studio-grade, in your browser

      The same thinking we put into every proposal. Nothing you enter leaves your phone.

      Real panel sizes

      Waaree 590, 615 and 700 Wp modules at their true size, with walkways at the edges and rows spaced for the winter sun.

      The real sun

      The sun’s path over your town every half hour of a typical day in each month, so shadows fall where they really will.

      Shade left out

      Any spot that would lose more than a fifth of its sunshine stays empty, and the plan tells you what is costing you.

      Questions

      Before you plan

      How many solar panels fit on my roof?

      It depends on the area left after walkways, the water tank, the stair room and shade, not on the size of the terrace alone. As a rule of thumb a plant needs 90 to 100 sq ft of shadow-free flat roof per kWp. The planner above lays real Waaree panel sizes on your actual roof and counts them for you.

      Why does the planner leave some spots empty?

      A panel that sits in a tank’s or a parapet’s shadow for long stretches of the winter drags down the whole string it is wired into. We leave out any spot that would lose more than a fifth of its sunshine, and keep 30 cm clear around everything on the roof.

      Is a raised structure worth it?

      Often, on a Bengal terrace. Lifting the panels about 7 ft clears the parapet’s shadow, lets low tanks stay underneath, and leaves the terrace usable for drying clothes or a get-together. It costs more steel, so we show both options in the proposal.

      How accurate is it?

      It is a planning tool, not a survey. Shadows come from the sun’s real path over your town; generation uses the same band as our calculator. A site survey and a 3D model of your actual roof replace every number before you sign anything.
