Large solar plants require regular maintenance to ensure optimal performance, including: Cleaning panels to remove dust and debris, checking electrical components and inverters, monitoring system performance, inspecting mechanical structures.
Proper maintenance keeps the plant efficient, minimizes downtime, and extends its lifespan.

The cost of a commercial solar power plant depends on several key factors: Project Size and Capacity, Site Conditions, Equipment Quality, Grid Connection, Permitting and Regulatory Compliance, Labor and Logistics.

A well-designed commercial solar power plant typically has an operational lifetime of 25 to 30 years. During this period, solar panels gradually experience a slight decrease in efficiency (usually around 0.5% to 1% per year). With proper maintenance and high-quality components, the plant can continue producing reliable energy well beyond 30 years.
