Is your roof ready for solar?

About 80–100 sq ft of shadow-free roof per kW with modern 540–580 W modules, including space for cleaning access. A 3 kW system needs roughly 270 sq ft; a 5 kW system about 450 sq ft.

South, tilted at about 15–23°, gives the highest annual output in Indore (latitude 22.7° N). East–west layouts produce 5–12% less in total but spread generation across morning and evening, which can suit some roofs and loads.

Yes, significantly. Even partial shade on a few cells can pull down a whole string. Half-cut modules and bypass diodes reduce the loss, but the best fix is layout and height — placing or raising modules so tanks, parapets, trees and neighbours don't shade them between 9 am and 4 pm.

Most RCC roofs are. Modules and a standard structure add roughly 15–20 kg per square metre, spread over pedestals or anchors. We inspect slab condition, cracks and seepage during the survey and design the structure accordingly.

Individual flats usually can't use the common roof without society approval. The practical route is a society-level system for common loads such as lifts, pumps and lighting, which qualifies for ₹18,000 per kW subsidy under PM Surya Ghar.

Not with an elevated structure. Raising the array on tall columns leaves the terrace usable underneath for drying clothes, gatherings or plants — and the shade keeps the roof and top floor cooler in summer.

It shouldn't. We use concrete pedestals or properly sealed anchors and route cables through conduits so the waterproofing isn't compromised. Elevated structures on pedestals avoid drilling into the slab surface altogether.
