A Rooftop Solar System generates electricity from solar panels installed on your building's roof, helping reduce electricity bills while utilizing otherwise unused space.

Battery Energy Storage Systems store electricity generated from solar or the grid and supply it whenever required. They improve energy reliability, reduce peak demand charges, and maximize renewable energy utilization.

A Hybrid Energy System intelligently combines Solar PV, Battery Storage, Grid Power, and, where required, Diesel Generators into one integrated energy solution that optimizes cost, reliability, and sustainability.

Adding Battery Storage enables you to:

• Store excess solar energy
• Use stored energy during evenings
• Reduce peak demand charges
• Improve backup power
• Increase energy independence
• Reduce dependence on diesel generators

Yes. Battery Energy Storage can be installed independently for backup power, peak demand management, load shifting, and power quality improvement.

Yes. Existing solar systems can usually be upgraded with Battery Energy Storage and intelligent energy management systems.

Modern BESS solutions incorporate advanced Battery Management Systems (BMS), fire detection and suppression systems, thermal monitoring, ventilation, and multiple safety protections that comply with international standards.

Solar panels typically perform efficiently for more than 25 years. Battery systems generally have an operational life of 10 to 15 years, depending on technology, operating conditions, and usage patterns.

Businesses can choose from: Many organizations combine multiple solutions to maximize savings and reliability.

• Rooftop Solar

Net Metering is a billing mechanism that allows electricity generated by your rooftop solar system and exported to the grid to be adjusted against the electricity you consume from the grid. This helps reduce your monthly electricity bill.

During the day, your solar system first supplies electricity to your premises. Any excess electricity generated is exported to the grid. When your solar system is not generating enough electricity, such as at night or during cloudy weather, electricity is imported from the grid. The utility adjusts exported and imported units according to the applicable Net Metering policy.

Eligibility depends on your state's electricity regulations, sanctioned load, system capacity, and DISCOM guidelines. Our experts assess your eligibility before designing the system.

Most states have Net Metering or related rooftop solar policies. However, regulations, system size limits, settlement mechanisms, and eligibility criteria differ from state to state.

Yes. MAKS Green Energy manages the complete Net Metering process, including:

• System design
• Application preparation
• Documentation
• Utility coordination
• Meter replacement
• Inspection
• Final commissioning

The treatment of excess exported energy depends on your state's regulations. Some DISCOMs allow adjustment against future consumption, while others may compensate according to the prevailing tariff or settlement mechanism.

Net Metering can significantly reduce your energy charges. However, customers may still be required to pay fixed charges, minimum charges, demand charges, or other statutory charges imposed by the utility.

Excess electricity is exported to the utility grid. The treatment of this surplus depends on the applicable state regulations and settlement cycle.

A standard grid-connected Net Metering system automatically shuts down during power outages to ensure the safety of utility personnel. If uninterrupted power is required, Battery Energy Storage should be installed.

Battery Storage is not mandatory. However, batteries provide:

• Backup power during outages
• Greater self-consumption of solar energy
• Peak demand management
• Improved energy independence

Yes. Modern Hybrid Systems combine Rooftop Solar, Net Metering, and Battery Energy Storage to maximize savings and provide backup power.

Under Gross Metering, all electricity generated by the solar plant is exported to the grid, while all electricity consumed is purchased separately from the utility. Billing and compensation are governed by the applicable state policy.

Virtual Net Metering enables electricity generated from a common rooftop solar installation to be allocated among multiple electricity consumers, such as apartments in a housing society, where permitted by state regulations.

Virtual Net Metering is primarily beneficial for:

• Apartment complexes
• Housing societies
• Residential communities
• Multi-tenant developments

Yes, subject to state regulations and sanctioned load limits. Larger consumers may also benefit from Open Access Solar depending on their energy requirements.

It depends on your electricity consumption and available rooftop space. Generally:

• Rooftop Solar with Net Metering is suitable for customers with adequate roof area and moderate energy demand.
• Open Access is suitable for larger consumers with higher electricity requirements or limited rooftop space.
• Many businesses combine both for maximum savings.
