Solar energy is energy from the sun that is converted into thermal or electrical energy. Solar panels (photovoltaic cells) capture sunlight and convert it into electricity using semiconductor materials that produce current when exposed to sunlight.
Installing a solar energy system helps reduce electricity bills, decreases your carbon footprint, increases property value, and provides energy independence. It also offers long-term cost savings and contributes to environmental sustainability.
The cost of a solar power system varies based on system size, location, installation complexity, and available incentives or subsidies. On average, residential systems range from $5,000 to $25,000 before incentives.
Yes, solar panels still produce electricity during cloudy or rainy days, though at a reduced efficiency. Modern systems are designed to be effective even in diffused sunlight conditions.
Solar systems require minimal maintenance. Periodic cleaning of the panels to remove dust or debris and occasional inspection of electrical components will keep the system operating efficiently.
Most solar panels come with warranties of 20–25 years, but they can continue to generate electricity for 30 years or more with gradual efficiency reduction over time.
Depending on your system size and energy usage, solar energy can significantly reduce your bill and, in some cases, bring it close to zero. However, you'll still pay basic grid connection or service fees unless you're fully off-grid.
If your system is grid-tied and doesn't include a battery backup, it will shut off during a power outage to prevent back-feeding electricity to the grid. Adding a battery storage system allows continued power during outages.
Most roof types, including asphalt shingles, metal, and tile, are compatible with solar installations. The orientation, angle, and structural integrity of your roof will affect system design and efficiency.
