Loom Solar Panel: Middle-class homes are shifting to rooftop solar because electricity bills have become a fixed monthly pressure, and Loom Solar panel system gets attention when the expectation is clear: reduce billed units and lock predictable savings. A 3kW rooftop size is the most practical search point because it fits common rooftops and matches daytime loads like fans, lights, fridge, TV, router, and limited AC use. The savings story becomes real when monthly generation stays in the 300–450 unit band and net metering is active, because that is what pushes the bill down sharply. For most families, the decision is simple: stable generation, safe installation, and service that keeps the system running without long downtime.
System And Installation Quality
A 3kW rooftop system is typically built with 6 panels of 540–550W or 7–8 panels of 375–450W, paired with a 3kW grid-tied inverter, mounting structure, DC/AC wiring, and protection devices. Rooftop space required stays around 180–250 sq ft depending on panel wattage and spacing. Mounting must be rust-protected and anchored properly for wind safety. DC cable must be UV-rated and routed inside conduit. Proper earthing and surge protection reduce inverter damage risk during storms and voltage spikes, because weak protection is the fastest way solar savings collapse.
Daily Generation And Bill Savings
A 3kW system typically generates 10–15 units per day in many Indian cities, which equals 300–450 units per month across seasons. At ₹8 per unit tariff, monthly saving value becomes ₹2,400–₹3,600, and at ₹9 per unit it becomes ₹2,700–₹4,050. Savings become stronger when daytime self-consumption is higher because solar units get used directly and reduce billed units instantly. Summer output often stays higher and monsoon output drops, so a stable year-round planning band for many homes sits around 300–400 units per month rather than the peak month number.
Net Metering And Output Factors
Net metering decides whether surplus daytime units reduce the bill or get wasted. Working families benefit more when export credits are applied correctly because the home stays empty during daytime. Output drops with shade, dust, and poor tilt angle, so placement planning matters more than brand name. Shade from a water tank for 1–2 hours daily can reduce monthly generation sharply. Cleaning every 15–30 days protects output in dusty regions. Inverter monitoring helps track daily units and detect faults early so the system does not stay off without the homeowner noticing.
Warranty, Maintenance And Safety
Panels usually carry long performance warranty terms, while inverters often carry 5–10 years depending on model and AMC. Maintenance is mostly cleaning and yearly electrical inspection because grid-tied systems have no battery replacement cost. Safety must include DC isolator, AC MCB, surge protection device, and proper earthing to reduce shock and fire risk. Grid-tied solar shuts down during power cuts, so backup comfort needs a hybrid inverter and battery, which increases cost. Service response matters because one inverter failure can stop generation fully and destroy the monthly savings math.
Price, Subsidy And EMI Shock
A Loom Solar 3kW rooftop solar setup is expected to cost ₹1.45 lakh–₹2.10 lakh depending on panel wattage, inverter grade, structure quality, and wiring. Under the PM Surya Ghar subsidy structure for eligible residential users, subsidy can go up to ₹78,000 for systems capped at 3kW, which can bring effective net cost closer to ₹67,000–₹1.32 lakh after approval and subsidy credit depending on the selected package and eligibility. EMI can start at ₹2,499 per month with a ₹20,000 down payment on a 60-month plan for a net-cost case near ₹1.20 lakh, while a higher net-cost case near ₹1.55 lakh can sit around ₹3,499 EMI with a ₹25,000 down payment on the same tenure. With 300–450 units monthly generation at ₹8–₹9 per unit tariff, monthly saving value stays around ₹2,400–₹4,050, which is why 3kW rooftop solar feels like a direct bill-cutting tool for middle-class homes.
