A turnkey on-grid home system with subsidy-eligible (DCR) modules typically costs ₹58,000–₹78,000 per kW before subsidy in 2026, depending on size and structure. A 3 kW system is usually ₹1.75–2.05 lakh before the ₹78,000 PM Surya Ghar subsidy, so roughly ₹0.97–1.27 lakh after it. Elevated structures add about ₹8,000–₹15,000 per kW. ### What size solar system do I need for my home? Divide your average monthly units by about 120 (what 1 kW generates per month in Indore). A home using 360 units a month needs about 3 kW; 600 units needs about 5 kW. Our calculator reads your bill and does this for you. ### How much roof space does solar need? 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. ### Which direction should solar panels face in Indore? 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. ### Does shade affect solar panels? 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. ### Is my roof strong enough for solar panels? 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. ### Can I install solar if I live in an apartment? 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. ### Will I lose my terrace if I install solar? 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. ### Will solar installation damage my roof or cause leakage? 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. ### Can I buy solar on EMI or with a loan? Yes. Under PM Surya Ghar, public-sector banks offer collateral-free loans for home systems up to 3 kW at concessional interest (around 7%). For larger systems, banks offer solar loans at regular rates. We help with the paperwork. ### Is it better to pay cash or take a solar loan? If the EMI is lower than your monthly savings, a loan lets solar pay for itself from day one. Paying cash gives the highest lifetime return. Our calculator shows both the EMI and the monthly savings so you can compare. --- **Genius Solar Services** · G-1, Swarna Palace, Plot No. 1108, Scheme No. 114, Part 1, Vijay Nagar, Near MP Gramin Bank, Indore, Madhya Pradesh 452010 · Phone +91 98267 12299, +91 78288 12299, 0731 400 4499 · geniussolarservices@gmail.com · Mon – Sat · 10:00 am – 7:00 pm Source: https://geniussolarservices.com
