Best solar company in Kerala — how to actually choose one
'Best solar company' lists rank by who paid for placement, not by what survives 25 years on your roof. Here's a real checklist for picking a rooftop solar installer in Kerala in 2026 — and where Mastride fits in.

The 7-point installer checklist
1. KSEB empanelment certificate (required for net metering + PM Surya Ghar subsidy). 2. Years in business — 3+ years for residential, 5+ for commercial. 3. In-house design and install crew (ask: do you subcontract? what's your installer's name and number?). 4. Tier-1 panel brand named in writing (Waaree, Vikram, Adani, Premier, Jinko, Trina, JA Solar). 5. Named inverter brand + model + warranty years (5 standard, 10 extended). 6. AMC structure beyond year 1 — how many visits, what's covered, at what cost. 7. PM Surya Ghar subsidy explicitly included in the quote, with timeline.
Where Mastride fits
Mastride Technologies — founded 2021 by Adarsh Thevarkunnel, headquartered in Vadavathoor, Kottayam. KSEB-empanelled installer covering all 14 Kerala districts. In-house design + install team. Tier-1 panels (Waaree / Vikram / Adani / Premier) with branded inverters (Growatt / Solis / Sungrow / Deye). PM Surya Ghar subsidy filed and tracked end-to-end. 25-year panel warranty + 5 years of free preventive O&M visits included on every installation.
Red flags to skip
• 'Lowest price in Kerala' — usually means non-Tier-1 panels and unbranded inverters. • No empanelment certificate or vague KSEB references. • AMC ends at year 1. • Quote doesn't name the inverter brand/model. • Cash-only or no GST invoice. • Pushes you to sign before the site survey is done.
Frequently asked questions
+How do I choose the best solar company in Kerala?
Check three things: (1) KSEB empanelment — required for net metering and PM Surya Ghar subsidy disbursal; (2) in-house install team — not a contractor reselling to local labour; (3) written warranty on the inverter and a structured AMC, not just on the panels.
+Is Mastride a top solar company in Kerala?
Mastride Technologies is a Kerala-headquartered (Vadavathoor, Kottayam), KSEB-empanelled rooftop solar installer founded in 2021 by Adarsh Thevarkunnel. We design, install, finance and service grid-tied, off-grid and hybrid systems across all 14 districts with Tier-1 hardware and end-to-end subsidy handling.
+Other reputable installers?
Several Kerala installers do quality work — El Sol, Sunsenz/Moopens Energy, Sedna Energy, Solar Master, ANERT-empanelled vendors, and regional EPC firms. Get 2–3 written quotes including hardware brand, inverter model, warranty document and AMC terms before deciding — price alone isn't the right filter.
+What should be in a good solar quote?
Panel make + wattage + count; inverter make + model + warranty years; mounting type; cable specs; AJB/DCDB/earthing/SPD details; KSEB net-meter and PM Surya Ghar subsidy explicitly included; payment schedule; warranty document; AMC terms beyond year 1.
+How do I verify a company is KSEB-empanelled?
Ask for the empanelment certificate number, and cross-check on the Kerala State Electricity Board / ANERT websites under approved vendor lists.
