Top Mistakes to Avoid Before Installing Solar Panels in Kerala
Most solar mistakes happen before installation begins. Here is what Kerala customers should check before paying an advance.
By Solwiz Energy Team. Reviewed as organizational guidance by Solwiz Energy.
Mistake 1: Buying only by kW price
A kW price without scope is incomplete. Compare module, inverter, structure, protection, cabling, monitoring, warranty and service.
Mistake 2: Ignoring shade
Shade from trees, parapets, water tanks and nearby buildings can reduce generation. A site survey should check real solar access.
Mistake 3: Wrong system type
On-grid solar is good for bill savings. Hybrid solar is good for backup. Choosing the wrong type can create disappointment.
Mistake 4: Unclear subsidy expectations
Subsidy is process-driven. Customers should understand eligibility, documents, timelines and final approval control.
Mistake 5: No maintenance plan
Solar needs monitoring, cleaning guidance and fault response. A weak service plan can reduce long-term savings.
Better approach
Start with bill analysis, roof survey and a clear proposal. Solwiz Energy supports residential solar, commercial solar, and solar maintenance across Kerala.
FAQs
Should I choose the cheapest solar quote?
Not without comparing scope. The cheapest quote may omit protection, structure quality, monitoring or service.
