Question 1

How much can solar reduce my electricity bill?

Accepted Answer

If you are wondering how solar can reduce electricity bill, most commercial and industrial businesses in India can see a noticeable drop in their monthly power costs after installing the right solar system. For many factories, warehouses, and commercial buildings, solar can offset around 40% to 70% of daytime electricity use. The actual savings will depend on how much electricity your business uses during the day, your available roof space, working hours or shifts, your sanctioned load, and the electricity tariff charged by your DISCOM. You can also use our solar savings calculator to get a quick estimate based on your requirements. Businesses that use most of their power during daylight hours usually benefit the most because the solar energy generated can be used directly on-site. This reduces the amount of electricity you need to buy from the grid. However, the right system size matters. Installing a larger system does not always mean higher savings if your daytime consumption cannot use the electricity being produced. SolarMaxx carries out a feasibility study before recommending a system. It looks at your electricity bills, consumption pattern, roof area, and site conditions to estimate the suitable system size, expected solar generation, and potential savings for your business.

Question 2

How long does installation take?

Accepted Answer

A typical rooftop solar project of around 100 kWp to 500 kWp commercial solar installation takes 8 to 12 weeks from the initial site survey to final commissioning. The timeline depends on the size of the project, roof condition, system design, equipment availability, and the approvals required from the local DISCOM. A smaller and straightforward rooftop project may move faster, while a larger or more complex installation can require additional time for engineering and electrical work. The process normally starts with a site assessment and system design, followed by documentation and approvals. Once these are complete, the mounting structure, solar panels, inverters, and electrical equipment are installed. The system then goes through testing before it is connected to the grid and commissioned. SolarMaxx provides turnkey solar solutions covering design, engineering, procurement, construction, testing & commissioning and grid connection, helping businesses manage the entire project through one team.

Question 3

Will installation disrupt our production?

Accepted Answer

No, solar installation will not disrupt any production as in most cases, a well-planned commercial solar installation can be completed with little or no impact on your normal business operations. Most of the installation work takes place on rooftops or other unused areas, so your production floor can continue operating as usual. The work can also be planned around your factory shifts, working hours, and busy production periods to keep interruptions to a minimum. SolarMaxx already states that its installations are planned to avoid downtime and that most work is carried out without interfering with daily operations. Before installation begins, the team reviews the site, electrical setup, roof condition, and operating schedule. This helps decide when different parts of the work should be carried out and whether any special arrangements are required. In some cases, a short planned shutdown may be needed for final electrical connections or system activation. If required, this can usually be scheduled during non-working hours or a planned maintenance period.

Question 4

What is the payback period?

Accepted Answer

The payback period for industrial rooftop solar is typically around 4 to 5 years, although the exact time depends on your electricity tariff, daytime power use, system cost, and solar generation. Factories and industrial units with high daytime electricity consumption usually see faster returns because they can use more of the solar power generated on-site. Businesses paying higher electricity tariffs may also recover their investment sooner, as every unit of solar power replaces more expensive grid electricity. For example, an industrial unit paying around ₹7 to ₹10 per unit can often achieve an attractive payback when the solar system is correctly sized for its consumption. After the initial investment is recovered, the system can continue reducing electricity costs for many more years. SolarMaxx evaluates factors such as electricity bills, roof space, consumption pattern, and expected generation when planning a turnkey solar solution, helping businesses understand their estimated savings and payback before investing.

Question 5

Who handles DISCOM metering approvals?

Accepted Answer

SolarMaxx handles DISCOM metering approvals that supports the documentation and approval process required to connect your commercial solar system to the grid. For most grid-connected solar projects, the process involves submitting the required documents to the local DISCOM, applying for net or gross metering, completing technical checks, and coordinating the steps needed before the system can start operating with the grid. SolarMaxx handles the required documentation for DISCOM approvals which helps reduce the paperwork your internal team needs to manage. The exact process can differ depending on the state, local DISCOM, project size, and the type of solar connection. Approval timelines are also controlled by the relevant DISCOM, so they can vary from one project to another. As part of its end-to-end support, SolarMaxx helps businesses manage the documentation and verification involved in the solar project, making the process easier from installation through grid connection.

Question 6

What equipment brands do you use?

Accepted Answer

SolarMaxx works with established solar equipment brands that are selected based on the needs of each project. We work with globally recognised brands such as Jinko Solar, LONGi, Canadian Solar, Trina Solar, REC, Waaree, Saatvik, Vikram Solar, SolarEdge, and Sungrow. The exact equipment used can vary depending on the size of the system, site conditions, technical requirements, availability, and the needs of the business. Choosing solar equipment is not only about picking a well-known brand. Panel efficiency, inverter capacity, warranty terms, service support, and long-term performance also matter. These factors are considered before recommending the final combination of panels, inverters, mounting systems, and other equipment. This helps ensure that the solar system is designed to perform reliably for many years rather than simply using the same equipment for every site. Through its procurement services, SolarMaxx helps commercial and industrial businesses source suitable equipment while keeping system quality, performance, and project requirements in mind. The proposed equipment and specifications are shared with the customer before installation, so you know what will be used for your project.

Question 7

Do you offer Operations & Maintenance (O&M) after installation?

Accepted Answer

Yes, SolarMaxx offers operations & maintenance (O&M) after installation that provides long-term O&M support to help commercial and industrial solar systems continue performing efficiently after installation. O&M covers the regular checks and services needed to keep a solar plant working properly. This can include preventive maintenance, panel cleaning, system inspections, performance monitoring, repairs, and support when an issue is detected. SolarMaxx also uses real-time monitoring and performance reporting to help identify problems before they cause a major drop in solar generation. The exact O&M scope can vary depending on the size of the solar plant and the maintenance package selected. SolarMaxx offers customizable maintenance packages, which can include warranty support, panel cleaning, response-time commitments, and other services based on the needs of the site. Regular maintenance is important because even a well-designed solar system can lose performance because of dust, equipment faults, weather damage, or aging components. SolarMaxx Operations & Maintenance services are designed to keep the system monitored, maintained, and performing well throughout its operating life.

Question 8

Can we visit a running SolarMaxx project?

Accepted Answer

If you would like to visit a running SolarMaxx project, you can ask the SolarMaxx team whether a suitable operational site is available for a visit. A project visit can be useful before making an investment because it gives you a chance to see how a commercial or industrial solar system works in a real business environment. You can look at the panel layout, mounting structure, inverters, electrical setup, and overall quality of the installation. Where possible, the team can help identify a project that is similar to your business in terms of industry, system size, roof type, or power requirements. This can give you a more practical understanding of what a similar solar installation could look like at your own facility. SolarMaxx has completed projects across different industries and system sizes, including manufacturing facilities, religious & educational institutions and large captive solar plants. Site visits will depend on the location, availability, and permission of the existing customer. You can speak with the SolarMaxx team to check whether a relevant project visit can be arranged for your requirement.

Question 9

How do I know your generation estimate is realistic?

Accepted Answer

Want to know if your solar generation estimate is realistic, the best way is to look at the assumptions behind the estimate and compare the projected output with actual generation once the system is running. Before designing a system, SolarMaxx carries out a site assessment and feasibility study. This includes checking factors such as available roof area, shading, system size, local solar conditions, and expected power generation. SolarMaxx states that it uses conservative site irradiance data in its pre-feasibility studies rather than showing unusually high numbers simply to make the project look more attractive. The estimate should also clearly show how much electricity the system is expected to produce over time. This gives your business a realistic figure to use when calculating savings and payback. After the plant starts operating, you do not have to rely only on the original estimate. SolarMaxx provides real-time plant monitoring, where you can compare actual generation against projected generation.

Question 10

How does SolarMaxx structure commercial solar projects?

Accepted Answer

SolarMaxx structures commercial solar projects as turnkey EPC projects, managing the main stages from initial feasibility and design through installation, testing, and grid connection. For a CAPEX project, the business invests in and owns the solar plant. This means the electricity generated by the system directly reduces the amount of power purchased from the grid, allowing the business to benefit from the savings over the operating life of the plant. The process normally begins with a site assessment and feasibility study. SolarMaxx then works on system design, equipment selection, procurement, installation, and project management. Once the installation is complete, the system is tested and connected to the grid as required. SolarMaxx describes its turnkey EPC service as covering the project from concept and design through commissioning and grid connection. Eligible commercial and industrial businesses may also be able to claim accelerated depreciation on their solar investment, depending on applicable tax rules. After installation, SolarMaxx also offers operations & maintenance support to help monitor the plant, carry out preventive maintenance, and maintain system performance over time.
