Frequently Asked Questions

Yes, provided the system is correctly sized, safely engineered, and backed by service commitments. The real value is not just "free electricity"; it is long-term protection against rising power costs. Reddit buyers frequently ask about payback, monthly bill reduction, and whether the investment truly works in local weather conditions.

For institutions, the bigger question is: Can the system reliably reduce electricity costs for 20-25 years without becoming a service headache? IHS answers this through an Advanced Solar™ architecture built around generation accountability, panel-level visibility, and contract-backed service.

The biggest risk is not whether the system works on day one. The bigger risk is whether the installer answers the phone on day 365, year 5, or year 10. Market surveys and online Reddit discussions repeatedly show anxiety around warranty support, delayed repairs, installers going out of business, and owners being left to chase manufacturers or third-party repairers.

IHS positions this as an accountability problem, not just a technology problem: 2-hour response SLA, 36-hour repair/replacement SLA, dedicated account manager, bi-weekly inspections, and financial penalties in the contract.

A standard solar system often gives only one total generation number for the entire roof. That can hide weak panels, failed components, shading issues, dirt buildup, or underperforming strings.

Existing users with Standard solar systems, frequently complain that systems appeared "green" in the app while still underperforming materially. One recent example involved a user discovering the system was roughly 22% below expected output only after doing their own calculations.

IHS's Advanced Solar™ architecture uses SolarEdge optimisers with per-panel monitoring, so every panel can be tracked individually. If one panel underperforms, the system can identify it instead of hiding the problem inside one roof-level number.

Most solar proposals promise savings, but few explain what happens if the system does not deliver.

IHS's answer is direct: 100% solar generated units guarantee — if the system fails to deliver the committed generation, IHS pays. This converts solar from a vague savings promise into a measurable service commitment.

For institutional buyers, this matters because committees, trustees, and finance teams need a defensible answer: "What happens if the vendor's numbers are wrong?"

This is one of the most common hidden anxieties. Those wanting to switch to solar often raise concerns about roof leaks, roof penetrations, dead load, snow/load issues, and responsibility disputes after installation.

For institutions, the right approach is to treat the roof as a critical asset, not merely as empty space for panels. Before final approval, the solar vendor should assess available area, structure type, waterproofing condition, wind exposure, access paths, and load distribution.

At IHS Envirotek, we treat the roof as a critical asset, not just available space. We inspect, document, design, and install responsibly to ensure the solar system is safe, reliable, and suited to the building.

Typical roof loads with solar installed.

• RCC Roof Loads: Reinforced Cement Concrete roofs require structural support for approximately 2.5 kg/ft² of load for solar installations.
• Metal Sheet Roof Load: Metal sheet roofs have a lower structural requirement, approximately 1 to 1.5 kg/ft².

This is where Advanced Solar™ has a strong answer. In a standard string inverter system, rooftop DC cables can remain live at high voltage even after shutdown. IHS's architecture uses SafeDC™ technology, where each panel automatically shuts down to under 1 volt during shutdown or emergency conditions. It also includes Arc Fault Circuit Interrupter protection and DC SPD monitoring.

For schools, colleges, hospitals, churches, elderly homes, and public institutions, this is not a technical luxury. It is a board-level safety issue.

Normal inverter monitoring tells you how the overall system is performing. Panel-level monitoring tells you which exact panel is underperforming.

That matters because real roofs are imperfect. Some areas get shade. Some panels collect more dust. Some optimisers, connectors, or modules may fail. Without panel-level intelligence, a problem can remain hidden until the electricity bill exposes it months later. Existing solar users specifically discuss the pain of being surprised by high bills or undetected underperformance.

IHS's Advanced Solar architecture gives every panel its own optimiser and real-time visibility through the app.

Solar is low-maintenance, not no-maintenance.

Panels need periodic cleaning, electrical checks, structure inspection, monitoring review, and fault-response discipline.

IHS includes bi-weekly on-site inspections of the entire system including checking solar panels, cables and other components for damage, besides the scheduled cleaning as part of its Advanced Solar™ service architecture. This reduces the risk of silent generation loss from dust, loose connections, or early-stage faults.

The real question is not whether equipment can fail. All equipment can fail. The real question is: How fast is it detected, who owns the response, and who pays for delay?

Existing solar users and online discussions frequently mention inverter replacements, warranty claims, service department availability, labour charges, and confusion between manufacturer warranty and installer responsibility.

IHS Envirotek addresses this through real-time monitoring, a dedicated account manager, 2-hour response commitment, and 36-hour repair/replacement SLA and committed energy production.

On-grid solar generates power during the day. If generation exceeds immediate consumption, the surplus is exported to the grid through a net meter. At night, the institution draws power from the grid. The bill is then adjusted based on import and export rules applicable to the local DISCOM.

Discussions show that customers are often confused about whether exported units are carried forward, converted into money, or adjusted against future consumption.

For institutional buyers in Mumbai, the answer is always DISCOM-specific: Adani, Tata Power, BEST, or MSEDCL rules may differ. IHS Envirotek explains this clearly during the feasibility and proposal stage rather than leaving the client to decode the bill later.

A cheaper quote may still produce power, but the missing costs usually appear later: poor monitoring, unclear warranty labour, weak service response, roof-risk disputes, lower-quality installation, or no accountability for generation shortfall.

A cheaper system can look attractive on procurement day. The correct comparison is risk per watt over 25 years, not price per watt on Day 1.

As a standard practice, most people looking to switch to solar compare price per watt at the initial stage. But this says nothing about installer quality, service response, and long-term warranty support matter.

The better question is not "Who is cheapest?" It is: Who will take responsibility for safety, monitoring, service, and performance for the life of the system?

IHS's Advanced Solar™ is built on three pillars:

Accountability: Contractual 2-hour response SLA, 36-hour repair/replacement SLA, 100% solar generated units guarantee, financial penalties, dedicated account manager, and scheduled inspections.

Intelligence: System optimisers, per-panel monitoring, free lifetime monitoring, better long-term energy yield, and early fault detection.

Safety: IHS Envirotek is one of the very few solar companies that takes safety seriously and follows the solar safety and electrical compliance standards governed by the National Electrical Code of India (NEC) 2023 — including module-level shutdown to under 1 volt, AFCI protection, DC SPD monitoring, and emergency-safe architecture.

In simple terms: standard solar gives you panels on the roof. Advanced Solar™ gives you monitored, safer, accountable solar with service commitments written into the contract.
