A free solar site survey in Noida should do much more than just measure your roof; it should check safety, structure, wiring, shading, and documents so your rooftop system is accurate and subsidy‑ready. Use this checklist to know what a good installer (like SIA Solar or other EPCs in Noida) should cover in a professional assessment.
1. Basic Property and Consumption Details
Confirm address, contact details, and property type (independent house, apartment, villa, small commercial, etc.).
Note sanctioned load, connection type (single/three phase), and take copies of the last 6–12 months’ electricity bills to size the system properly.
2. Roof Condition and Structural Checks
Measure available shadow‑free roof area and note roof type (RCC, metal sheet, tiled, terrace with parapet, etc.).
Check roof age, waterproofing, visible cracks, and whether the structure can safely carry the extra load for 20–25 years; for weak or old roofs, structural certification may be recommended.
3. Orientation, Tilt, and Shading in Noida
Record roof orientation (south, east, west) and existing tilt, and identify best zones for maximum sunlight.
Map shading from water tanks, parapet walls, nearby buildings, and trees over the day, using shade analysis tools or at least multiple‑time visual checks.
4. Electrical Infrastructure and Safety
Locate main AC distribution board, meter, and earthing points, and record cable routes from roof to inverter and DB.
Note connection type, existing protection devices, and available space for inverter, DCDB/ACDB, and net meter; flag any need for upgrades to meet DISCOM and MNRE standards.
5. Net Metering, Policy, and Documentation Readiness
Confirm your DISCOM (e.g., NPCL/Noida Power or other Noida DISCOM) and discuss rooftop net‑metering requirements and document list (ID proof, ownership, load details).
Check if the site and proposed design can comply with current technical specifications for rooftop plants relevant to PM Surya Ghar and UP regulations.
6. Safety, Access, and Practical Considerations
Evaluate safe access (stairs, ladders, parapets) and potential anchor points or walkways for installation and future cleaning.
Plan inverter and monitoring device locations so they stay shaded, ventilated, and close enough for easy reading and Wi‑Fi or data connection.
7. What You Should Receive After a Good Site Survey
A basic sketch or layout of panel placement, estimated system size (kW) based on your bills and roof area, and indicative generation potential for Noida’s conditions.
A short site report or checklist summary with photos, roof and electrical notes, shading observations, and next steps for design, quotation, and subsidy/net‑metering application.
FAQs
Q1. What is checked in a free solar site survey in Noida?
A proper survey checks roof condition, area, shading, electrical setup, safety, and your electricity usage before recommending system size and layout.
Q2. How much roof space do I usually need?
Many guides suggest roughly 100 square feet of shadow‑free area per kW of rooftop solar, depending on panel efficiency and layout.
Q3. Why is shading analysis so important?
Even partial shading can noticeably reduce output, so installers map obstacles and sun paths to place panels in the best‑lit zones.
Q4. Do I need to arrange any documents before the survey?
Keeping your latest electricity bills and basic property details ready helps the engineer size the system and plan net‑metering requirements.
Q5. Should the installer give me a survey report?
Yes, a professional installer should share at least a simple layout, key measurements, shading notes, and initial system sizing after the site visit.
