What Heliostrom Customers Say
Dr. Palanivasan
Vadapalani, Chennai
“Young and professional team. Advised me with the correct requirements and completed on time.”
Priya Chandrasekaran
T. Nagar, Chennai
“Got three quotes from different installers. Heliostrom was the only one who visited the site twice before finalising the design. That thoroughness made us choose them.”
Anand Krishnan
Madurai
“Hybrid system with battery backup for our medical equipment at home. Heliostrom designed a custom solution, not a template. Running perfectly through every grid outage.”
Meena Subramanian
Tambaram, Chennai
“Heliostrom was the only company that gave us an honest assessment of realistic savings — no overselling. Bills reduced every single month.”
Suresh Rajan
Anna Nagar, Chennai
“After comparing four solar companies in Chennai, we chose Heliostrom for our office. The entire process from site visit to TANGEDCO net metering was managed by their team.”
Rajesh Kumar
Coimbatore
“Was worried about after-sales support from a Chennai-based company. But the team was responsive every time.”

Suitability
Can Your Rooftop and Electricity Demand Support 100 kW?
A 100 kW proposal needs more than an estimate of roof dimensions. The survey should establish how much area is genuinely usable, how equipment will be arranged and how generation aligns with the building’s daytime demand.
Roof suitability
Check structural condition, roof type, shade and safe installation and cleaning access.
Demand profile
Review daily use, business hours, weekends and seasonal changes.
Layout and equipment
Establish module capacity, inverter configuration and the cable routes needed for the design.
Electrical connection
Confirm integration requirements and any separate strengthening or upgrade work.
Generation and space requirements should follow the proposed layout and site assessment. Review annual output with stated weather, shade and system-loss assumptions. Distinguish module capacity in kWp DC from inverter or output capacity in kW AC.
A standard grid-connected plant normally shuts down during a grid outage. Any storage or generator integration requires a separate appropriate design and must not be assumed to be included.
Cost and quotation
What Your 100 kW Solar Quotation Should Include
A useful 100 kW solar plant quotation identifies the equipment and the work behind the price. Confirm whether offers include comparable mounting, electrical protection, installation, testing and documentation assistance before judging them on cost.
Indicative market budget · planning estimate, Nov 2026
Indicative market budget: ₹41–₹47 lakh for a 100 kW grid-connected rooftop installation. This is a planning estimate, not a Heliostrom quotation. Final pricing follows site assessment and written scope.
Budget basis: November 2026 public market references for complete on-grid rooftop systems. Source prices are presented as installed totals; confirm the applicable taxes and exact scope in the final quotation. Before any subsidy adjustment. Batteries, land purchase, major roof strengthening, substantial civil works and electrical infrastructure upgrades are outside this planning basis unless expressly included. DC/AC sizing and equipment remain subject to design.
Check that your quotation covers
- Modules, inverter, mounting and agreed electrical protection.
- Installation, testing and the defined commissioning scope.
- Applicable documentation assistance and connection responsibilities.
- Any separately priced roof, civil or electrical upgrade work, batteries or additional integration.
- Payment milestones, warranty responsibilities and maintenance terms.
Savings depend on generation, the amount consumed on site, electricity rates and treatment of exports. Fixed or demand charges may remain. Payback estimates should include operating costs and state the assumptions rather than promise a standard return.

Project Delivery and Long-Term Support
Understand the delivery stages and the responsibilities at each step before work begins. The project schedule depends on site readiness, equipment availability and applicable approval or connection requirements.
Site assessment: Review consumption, installation area, access and electrical conditions.
Design and proposal: Agree capacity, equipment, scope, exclusions and project milestones.
Installation: Coordinate mounting and electrical work with the site owner and agreed safety arrangements.
Testing and commissioning: Complete the defined checks, documentation and applicable connection steps.
Handover and support: Review operating guidance, monitoring access where included, warranty documents and service contacts.

Manufacturer product cover, performance warranties and installation workmanship terms differ. Confirm the responsible party and exclusions for each. Where maintenance is offered, agree cleaning access, inspection scope, reporting and charges in writing.
For project coordination, contact Heliostrom. Existing customers can use the customer support page.
Discuss Your 100 kW Solar Requirement
The proposed array needs a site-specific shading assessment. Obstacles, access paths and roof restrictions affect the usable area and layout.
The proposal should distinguish module capacity in kWp DC from inverter or output capacity in kW AC and identify the equipment configuration.
Check equipment models, mounting, protection, taxes, installation responsibilities and exclusions. A lower price may reflect a different scope.
A standard on-grid system normally shuts down during an outage. Backup needs a separately engineered configuration and suitable equipment.
Ask Heliostrom for the available references, actual installation scope and after-sales arrangements relevant to your requirement. Project capacities and customer locations should be stated accurately.
