As India’s solar sector expands under schemes like the PM Surya Ghar Yojana, the pressure on installers to deliver safe, efficient, and compliant systems has never been higher. While demand is rising, so are inspection standards, audit checks, and subsidy requirements from DISCOMs, MNRE, and BIS.

At Feston SEV, we work closely with solar professionals across India. We’ve seen how minor mistakes — like incorrect wiring or outdated documentation — can cause major delays. So here’s a guide to the top mistakes to avoid in 2025, and how to stay ahead with Feston-certified systems.

❌ Mistake 1: Using Non-BIS Certified Components

What goes wrong: Installers often use cheaper, uncertified inverters or panels to reduce costs.
Impact: Subsidy claims get rejected, net metering is delayed, and system performance drops.

✅ Feston Fix:
All our inverters (IS 16221, IS 16169) and DCDB/ACDB units (IS 16270) are BIS-compliant and quality-assured.

❌ Mistake 2: Not Checking ALMM Compliance

What goes wrong: Installers use PV modules not listed under MNRE’s Approved List of Models and Manufacturers (ALMM).
Impact: Government subsidies are denied, even if the system is otherwise functional.

✅ Feston Fix:
We ensure ALMM-listed modules and partner with OEMs who are subsidy-ready under national guidelines.

❌ Mistake 3: Skipping Single-Line Diagrams & Safety Labels

What goes wrong: Projects are submitted without SLDs, fuse ratings, SPDs, or labelling of wires and isolators.
Impact: Site inspections fail, especially in states like Gujarat, Rajasthan, and Tamil Nadu.

✅ Feston Fix:
Our systems come with documentation kits, including sample SLDs, pre-labelled components, and installation guides aligned with state-specific DISCOM protocols.

❌ Mistake 4: No Remote Monitoring or Anti-Islanding

What goes wrong: Installers deploy older inverters that lack remote monitoring or anti-islanding protection.
Impact: System registration gets denied in many DISCOMs, such as in Delhi and Maharashtra.

✅ Feston Fix:
Feston inverters come with real-time monitoring via the FestonCare App and have built-in protections that meet MNRE and CEA standards.

❌ Mistake 5: Poor Quality Earthing or SPDs

What goes wrong: In a rush, installers ignore grounding depth, don’t test resistance, or skip surge protection.
Impact: Risk of electrical faults, fire hazards, and failed safety audits.

✅ Feston Fix:
We offer ready-to-use ACDB/DCDB units with built-in SPDs, weatherproof enclosures, and detailed earthing recommendations per IS 3043.
