Solar panels absorb sunlight and convert it into direct current (DC) electricity. An inverter then converts this into alternating current (AC), which powers your home or business.

High-quality solar panels typically last 25–30 years, with efficiency gradually decreasing over time. Most manufacturers offer warranties of 20–25 years.

Yes, solar panels generate electricity even on cloudy or rainy days, but at a reduced efficiency. They perform best under direct sunlight.

Yes, with a properly sized solar system, you can generate enough electricity to meet all your energy needs. Battery storage can further help provide power at night or during outages.

Solar panels require minimal maintenance. Occasional cleaning and regular inspections ensure optimal performance and longevity.

Savings depend on your electricity usage, system size, and local energy rates. Many homeowners reduce their electricity bills by 50–100% after switching to solar.

A battery system is optional but beneficial. It allows you to store excess energy for use at night or during power outages, improving energy independence.

A typical residential installation takes 1–3 days, but the entire process, including permits and approvals, may take a few weeks.

Many governments and utilities offer tax credits, rebates, and financing plans to make solar more affordable. Our team can help you explore available incentives.

Yes, studies show that homes with solar panels sell faster and at a higher value compared to non-solar homes, making it a great investment.
