Not all companies offer the same quality, services, or prices. Paying attention to these factors will help you make a smart decision. ### Quality of Solar Panels The quality of solar panels is the most important factor. High-quality panels produce more electricity and last longer. There are three main types of solar panels: * Monocrystalline panels: Very efficient and durable, slightly more expensive. * Polycrystalline panels: Less efficient but more affordable. * Thin-film panels: Lightweight and flexible, but lower efficiency. Always check the efficiency rating of the panel and the warranty offered by the company. Good panels usually last 20–25 years. ### Installation Expertise Even the best panels will not perform well if installed incorrectly. Professional installation is key. Check if the company has: * Experienced and trained technicians * Proper safety procedures * Experience in installing panels for homes, apartments, and offices ### After-Sales Service & Maintenance Solar panels need regular maintenance to work efficiently. Choose a company that provides: * Warranty on solar panels and inverters * Periodic maintenance services * Quick response for technical issues A company with good after-sales service ensures your solar system works efficiently for many years. ### Cost & Financing Options Cost is an important factor. However, the cheapest option may not always be the best. Look for a company that offers: * Transparent pricing without hidden charges * EMI options or financing solutions * Guidance for government subsidies to reduce upfront costs Top Solar Companies in Kolkata ------------------------------ Here is a list of the best solar companies in Kolkata.
