FAQ
Q: What is renewable energy?
A: Renewable energy is any resource that is readily available in nature (eg., sun, wind, water, thermal heat, and plants).
Q: Why should I use renewable energy?
A: Using renewable (eg., solar) energy technology has many environmental benefits, as it has little environmental impact. The use of photovoltaics (PV’s) to transform sunlight into electricity produces no pollution. Because its source, sunlight, is free and readily available, continual access to this resource is guaranteed. As more people get involved with the renewable energy movement, the cost of production of solar energy products decreases, making solar energy more affordable for everyone. Taking part in a relatively new, high-tech industry helps create jobs, which in turn strengthens the economy.
Q: Is there enough sun in our area to produce adequate amounts of electricity?
A: Absolutely! Photovoltaic (PV) systems can operate in most climates, regardless of inclement or severe weather. Actually, some PV systems work better in colder temperatures. When PV modules are installed, they are oriented to collect the maximum amount of the sun’s rays, so any snow that collects on the modules will melt quickly. Thus, there is enough sunlight available nearly everywhere in the United States to make the use of solar energy feasible.
Q: What is included in a basic solar energy system?
A: The size of the system will vary according to several factors, including the amount of energy you need to produce, access to sunlight, and orientation of the installation site. The very basic system will include: a photovoltaic (PV) module; batteries; an inverter (for a system connected to utilities, to convert AC/DC); a charge regulator or controller for a stand-alone system; wiring; and mounting hardware or a framework.
Q: What is the average cost of a solar energy system?
A: Cost of solar energy systems vary widely, depending on energy needs, solar conditions, and whether the system is part of new construction (less costly) or being retrofitted to an existing structure (more costly). A basic residential system can begin around $7,000, and a more sophisticated commercial system can begin around $20,000. Taking advantage of government incentives can greatly reduce the financial impact of going solar, sometimes cutting costs in half!
Q: Are there any incentive programs or rebates offered to help defray the cost of a solar energy system?
A: Yes, there are federal and local tax incentives, rebates and low-interest loans available. For more information on what these incentives are and how you can access them, visit dsireusa.org.
Q: Do solar energy systems come with a warranty?
A: Yes. Most inverters come with a 10-year manufacturer warranty, and most photovoltaic (PV) modules come with a 25-year manufacturer warranty. See manufacturer details for warranty information.
Q: How long do photovoltaic panels typically last?
A: High-quality photovoltaic (PV) panels are durable, built with strong aluminum frames and high-strength tempered glass, which will withstand moderate to severe weather. With proper use and maintenance, you can expect PV panels to last anywhere from 30 to 50-plus years. Some solar systems installed back in the ‘60’s are still working to produce electricity today!
Q: What kind of maintenance is required for solar electric systems?
A: There is no daily maintenance required for the care of photovoltaic (PV) modules. You can just sit back and let the sun work for you! Most manufacturers recommend cleaning the modules once or twice a year, which simply means hosing them off to remove dust and particles which can accumulate to reduce effectiveness.
