What is photovoltaic (solar) energy?
Photovoltaic energy is electricity generated from sunlight using solar panels, which convert solar radiation into usable electrical power.
How do solar panels work?
Solar panels are made up of photovoltaic cells that capture sunlight and convert it into direct current (DC). This is then transformed into alternating current (AC) by an inverter, making it usable for homes and businesses.
What is the lifespan of a solar energy system?
Solar panels typically last between 25 to 30 years. Inverters generally have a lifespan of 10 to 15 years, depending on the brand and how well they’re maintained.
How much maintenance do solar panels require?
Very little. The main requirement is to keep them free of dust and debris. An annual technical inspection is recommended to ensure everything is running efficiently.
Do solar panels work on cloudy or rainy days?
Yes. While production is reduced, panels still generate electricity using diffused sunlight. Systems can also be paired with batteries or connected to the grid to ensure consistent power.
What happens if I generate more energy than I use?
If your system is grid-connected, you can feed the excess energy back into the grid and receive credits or compensation, depending on your country’s regulations (e.g., net metering).
Which type of solar system is right for me: grid-tied, hybrid, or off-grid?
Grid-tied: Ideal for lowering electricity bills.
Hybrid: Combines solar panels, the grid, and battery storage.
Off-grid: Perfect for remote locations with no grid access.
What are the benefits of solar energy?
Significant savings on electricity bills
Clean, renewable energy
Greater energy independence
Increased property value
How much does a solar system cost?
Costs vary based on system size, equipment quality, and installation type. A residential system typically ranges from $3,700 to $10,000 or more, depending on its capacity and features.
Do I need permits to install solar panels?
Yes. In most countries, an electrical or interconnection permit is required. It’s important to work with a qualified installer who can handle the permitting process for you.
