When considering residential solar panels for your home, it’s only natural to have many questions. After all, this is going to be an investment of a lifetime so it helps to know as much as you can before delving forward.
Listed below are some of the most frequently asked questions about solar panel installations:
1) How do residential solar panels work?
Solar panels are a part of a PV or photovoltaic energy system. This also includes mounting racks for the panels, an inverter and the electrical wiring. From the period of sunrise to sunset, your solar panels will amass sunlight (solar energy) and generate direct current (DC). Then it’s sent to an inverter where DC will be converted into alternating or AC current. This form of current is used in homes. Some solar panel systems do not require an inverter because they have micro-inverters built into each solar panel. After converting DC into AC power, it travels via your home’s main electrical panel for your home’s use.
2) How does shade impact the performance of my solar panels?
It’s imperative that you minimize shading for optimal solar panel performance. Ideally, you should take care to trim trees and remove any obstacles that might reduce panel output prior to the installation. Solar panels work best when entire surface is completely exposed to sunlight. Although your system will produce energy if any portion is shade, the output will reduce.
Your installer will assess your location and decide whether your home is ready for solar technology. He or she may also suggest areas that need to be improved.
3) How long can I expect my panels to last?
Modern solar panels exhibit some of the latest advancements in technology. As a result, most solar panels do last up to 40 years; provided you follow minimum maintenance guidelines. Most solar installers/manufacturers offer a warranty period for a certain period of time with an option to purchase extended warranty.
4) How much money can I expect to save with my solar panels?
Your current monthly usage and the size of your solar system will determine your savings amount. Since most solar panel installations have next-to-no or very minute start-up costs, the system begins to pay for itself the moment you hit the ‘on’ switch.
Your savings figure will fluctuate according to factors such as:
- System size
- Home’s average energy use
- Performance of the solar panels
- Tax incentives
- Solar energy buy back rates provided by the utility company
- Solar credits, etc.
Your installer can provide detailed information about system costs and expected savings.
5) Having a solar panel increase my property taxes?
The answer to this question depends on which state you live in. However, an installed solar system increases the value of your home considering most homebuyers today are interested in seeking alternative energy means.
