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.
