What Is a 4 kw Solar System?
A 4 kw solar system (also referred to as the 4 kw solar system price capacity) generates approximately 3,600–4,800 units (kWh) per year—enough to meet the electricity needs of a typical Indian household consuming 400–500 units monthly. These systems are ideal for small to midsized rooftops and can power most lighting, fans, fridge, water pumps, and even small EV chargers.
Components typically include:
- Solar PV Modules (monocrystalline or polycrystalline), usually 10‑14 panels @300–400 W
- On‑grid string inverter(s) converting DC to AC
- Mounting structure, cables, DC fuses, soft start kit
- 3‑phase Bi‑directional net meter (provided by DISCOM)
- Optional battery for partial backup or hybrid use
- Installation and commissioning charges
The 4 kw solar panel price often refers to the PV module cost only (about ₹1.1–1.5 lakh as of mid‑2025), while the complete 4kw solar system price (including inverter, PE kit, installation, documentation) typically ranges from ₹2.2–2.9 lakh before subsidy
