We understand solar technology is new for many of our customers, so we've compiled a list of frequently asked questions. We hope our FAQ will clear up any questions you may have about solar energy, however, if you have an inquiry that is not addressed on this page, simply email us at info@vanguardsolartechnologies.com or call us at 305.817.8211.
Q: What is photovoltaics (solar electricity), or "PV"??
A: What do we mean by photovoltaics? The word itself helps to explain how photovoltaic (PV) or solar electric technologies work; they convert light energy to electricity.
Q: What are the components of a photovoltaic (PV) system?
A: VISS are made up of different components. These include PV modules (solar panels), which are commonly called PV panels; micro-inverters for a utility-grid-connected system; wiring; and mounting hardware or a framework. VISS do not use expensive and hard to maintain batteries making them more affordable.
Q: How long do photovoltaic (PV) systems last?
A: A PV system that is designed, installed, and maintained well will operate for more than 25 years. The basic PV module (solar panel) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it properly designed, installed and maintained.
Q: How much electricity does a photovoltaic (PV) system generate?
A: VISS are designed to produce from 1% to 100% of our customers’ powers needs. And because these systems are easily expandable, future additions are simple and cost effective with no need to replace expensive equipment. They are basically “plug and play”.
Q: Can I use photovoltaics (PV) to power my home?
A: Of course, PV can be used to power your entire home's electrical systems- including lights, cooling systems, and appliances. PV systems today can be blended easily into both traditional and nontraditional homes.
Q: Can I use photovoltaics (PV) to power my business?
A: Yes! PV systems can be blended into virtually every conceivable structure for commercial buildings. You will find PV being used outdoors for security lighting as well as in structures that serve as covers for parking lots and bus shelters, generating power at the same time. Indoors, PV systems are used to offset and operate all kinds of electrical systems, including lights, cooling systems, and appliances.
Q: Can I design and install a photovoltaic (PV) system myself?
A: Maybe! However, we can design your system bases on your specific need at no extra charge. Installation is another matter, only Licensed Contractors are authorized to install these systems. Vanguard Solar Technologies provides these services and guarantees that your system will perform as designed and will be properly installed.
Q: Why should I purchase a PV system?
A: People decide to buy solar energy systems for a variety of reasons. For example, some individuals buy solar products to preserve the Earth's finite fossil-fuel resources and to reduce air pollution. Others would rather spend their money on an energy-producing improvement to their property than send their money to a utility. Some people like the security of reducing the amount of electricity they buy from their utility, because it makes them less vulnerable to future increases in the price of electricity. Also, State and Federal incentives make purchasing PV systems easier than ever.
Q: Are there disadvantages to using solar energy?
A: Solar energy technologies often have a higher "first cost." This means that a person is likely to pay more money up front to purchase and install a solar system. Still the high initial cost is recovered in 5 to 8 years, then benefiting from the savings over the life of the product (25-30 years).
Q: How is a solar electric system designed, installed, and maintained?
A: You could install a photovoltaic (PV) or solar electric system yourself. But to avoid complications or injury, you will probably want to use Vanguard Solar Technologies with experience in installing solar systems. PV systems have few moving parts, so they require little maintenance. The components are designed to meet strict dependability and durability standards so they can stand up to the elements. However, they are fairly sophisticated electric systems, so installation usually requires the knowledge and experience of a licensed electrical equipment contractor.
Q: How much does a solar energy system cost, and how much will I save on utility bills?
A: Based on recent installations, a 5kW system (produces an average of 1,000kW/hour) will cost about $10,000.00 after Florida and Federal incentives.
Q: Can I afford photovoltaics (PV)?
A: Yes! VISS are specifically designed to be expandable. You can buy the system that fits your budget and start saving money right away. In the future, adding more panels will be easy and cost effective.
Q: How do I find out about financial incentives such as rebates or tax credits in my home state?
A: Check out our Information page or call us at 305.817.8211.
Q: What resources, grants, loans, and other incentives are there for installing a PV system?
A: Check out our Information page or call us at 305.817.8211.
Q: What is net metering? Is net metering available where I live and work?
A: Net metering is a policy that allows homeowners to receive the full retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the photovoltaic (PV) system's electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner's PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid.
Q: What is an average break-even point for a solar energy system?
A: It depends. The break-even point for a system depends on financing and incentives, which vary from place to place, and it depends on your solar resources and what you would pay for another source of energy. Taking in consideration State and Federal incentives, PV systems will recover the initial cost within 5 to 8 years.
