Several myths and misconceptions surrounding residential photovoltaic systems discourage people from installing them at home. It is generally believed that solar energy installations are expensive and non-durable. Therefore, they are used only by the environment-conscious people. However, with the introduction of thin film photovoltaic solar energy systems, none of these theories hold true. The new thin film PV technology supports quick manufacture of devices by automated processes, thus reducing cost of production. They have also proven to be more durable and functional.
There are some essentials that you must be aware of regarding photovoltaic solar energy systems before making a purchase decision.
Residential Photovoltaic Systems: FAQs
Some of the frequently asked questions regarding residential photovoltaic system and its functionality are as follows:
How does a home solar electric system operate?
Solar cell units installed on the rooftop convent natural light into DC power, which is then converted into AC power by an inverter for residential use. The overhead system is connected with the utility at home. During daytime, if the solar system generates more electricity than is required by your home, your utility will allow the excess power to be returned to the grid. This power saved in the grid would be used at night as well as during the day, when electricity demands exceed the amount of power provided by the solar system.
Do the system home solar power kits function at night and during cloudy days?
These systems do not function at night because solar modules require sunlight to generate power. At night, your home utility would provide power.
The photovoltaic system can produce electricity even when the sky is overcast, although in less quantity. In fact, the solar panels would generate half as much as they do under clear skies.
Will the solar system generate sufficient energy to fulfill all electricity needs?
It is important to note that the value of a solar residential system does not rest on its ability to provide for all electricity requirements. Even a small system shifting your electricity demand from one-quarter to half will reduce your electricity bill to a great extent. With better backup, such a system can deliver uninterrupted supply for days or even weeks, in case of continuous power shortage. However, the aim behind the system is to reduce your electricity bill by half.
We are happy to provide you with a system that supplies 100 percent of your energy needs, but cutting your electricity by 40 to 50 percent is typically the most cost-efficient approach for home solar power.
