Off-Grid Solar PV Systems

An off-grid solar PV system is designed to operate independently of the utility grid, providing a self-sufficient energy solution for locations without grid access or where energy independence is essential. These systems rely on solar panels and battery storage to meet all energy demands.

Key Features of Off-Grid Solar PV Systems:

100% Energy Independence:

Off-grid systems eliminate reliance on the utility grid, making them ideal for remote areas or users seeking complete autonomy.

Battery Storage for Energy Reserves

Excess solar energy is stored in batteries, ensuring a reliable power supply during nights or cloudy days.

Customizable Solutions

Off-grid systems are tailored to meet specific energy needs, whether for a small home, a business, or a large-scale project.

Reliable in Remote Areas

Perfect for rural or isolated locations where grid access is unavailable or cost-prohibitive.

Why Choose an Off-Grid Solar PV System?

Off-grid systems are ideal for those living in remote areas or anyone seeking total energy independence. They ensure a consistent power supply without the need for grid connectivity, making them a reliable solution for sustainable living.
Why Choose Rooftop Solar?

Top Reasons to Choose Solar Energy

An off-grid solar system operates independently of the utility grid. It uses solar panels to generate power and battery banks to store excess energy for nighttime or cloudy conditions.
Panels produce DC electricity → charge controller stores it in batteries → inverter converts DC to AC power for household use. No grid connection is needed.
Ideal for remote locations with unreliable or no grid supply---such as farms, resorts, construction sites, and rural homes seeking energy independence.
  • On-Grid: Tied to utility grid, no batteries.
  • Off-Grid: Fully independent with batteries.
  • Hybrid: Combines both for flexibility.
Yes. They work well in places with frequent outages or for users wanting backup independence from the grid.
  • Solar Panels (Vikram Solar, Tata, Waaree, RenewSys)
  • Charge Controller (MPPT based)
  • Inverter (GoodWe, Growatt, Solis)
  • Battery Bank (Lithium-ion or Tubular Lead-Acid)
  • AC/DC Distribution Boards
  • Cables, Earthing Kit, Lightning Arrester
Either tubular lead-acid or lithium-ion batteries. Energyspoc recommends lithium-ion for longer life (10 + years) and faster charging.
Depending on capacity, batteries can run essential loads for 8--16 hours without sunlight.
Yes. All panels, inverters and BoS parts meet MNRE, BIS and IEC quality standards.
Yes. We use IP65/IP67-rated hardware and marine-grade aluminium structures tested for coastal conditions.
Each 1 kW of solar capacity produces ≈ 4 units per day in Mumbai (≈ 1,400--1,500 units annually).
Yes, with proper design and battery sizing. We customize solutions to match your load profile and backup needs.
Yes. Generation drops slightly, but stored battery power maintains continuous supply.
Yes. Energyspoc designs high-capacity systems with adequate battery and inverter ratings for heavy loads.
Yes. Off-grid systems can power dedicated EV charging stations with battery backup.
Typical range (including batteries and installation):
  • 3 kW -- ₹2.2 -- ₹2.5 lakh
  • 5 kW -- ₹3.4 -- ₹3.8 lakh
  • 8 kW -- ₹5.4 -- ₹5.9 lakh
  • 10 kW -- ₹6.8 -- ₹7.4 lakh
Direct MNRE subsidy is only for grid-connected systems. However, local schemes and financial assistance may apply for rural projects.
Payback usually takes 4--6 years, depending on battery capacity and usage pattern.
Yes. Batteries account for ≈ 35--40 % of the total project cost, but they provide complete energy autonomy.
Yes. We offer EMI and lease options through our financial partners.
1 Site Assessment → 2 Design → 3 Quotation → 4 Installation → 5 Testing → 6 Handover with training. Energyspoc manages everything end-to-end.
5--10 days for homes; 10--15 days for larger projects.
No. We use waterproof, non-penetrating mounts suitable for RCC and metal roofs.
No. Since off-grid systems don't connect to the utility grid, no DISCOM permission is needed.
Clean panels every two weeks and schedule battery checks twice a year. We provide AMC services across Mumbai and MMR.
  • Panels -- 25 years performance
  • Inverter -- 5--10 years
  • Battery -- 5--10 years (depending on type)
  • Mounting & BoS -- 5 years
We supply and install compatible batteries and dispose of old ones safely per E-Waste rules.
Yes. They include over-current protection, surge arrestors, and proper earthing as per IS/IEC standards.
Yes, if properly sized. We design systems with high starting-torque inverters for motors and agricultural loads.
Standard installation includes DC isolators and MCBs. We recommend a basic ABC fire extinguisher near the battery bank.
Yes. They instantly switch to battery power when grid supply fails, ensuring uninterrupted electricity.
Yes. They serve as backup for hospitals, clinics, shops and residences where power stability is critical.
Yes. We cover the entire MMR region including Thane, Navi Mumbai, Pune and Konkan belt.
