Frequently Asked Questions about Solar Photovoltaics

1、Who can install solar panels on my property?
Finding a competent installer is important. There are currently no formal qualifications mandated which installers must hold, but connection of the solar system must be carried out by a Registered Electrical Contractor. SEAI’s advice would be to contact multiple installers or developers to get a range of quotes. A good place to start is the Renewable Installers Register which identifies installers that have received accredited training.

2、What are the components of a photovoltaic (PV) system?
A PV system is made up of different components. These include mounting hardware or a framework which are produced by solar mounting rack unistrut manufacturer , PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required.

3、How long do photovoltaic (PV) systems last?
A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (solar panel bracket aluminum ,interconnected, enclosed panel of PV cells) 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 installed and maintained properly. Experience has shown that most problems occur because of poor or sloppy system installation.

4、What is the weight of the solar system on the roof?
The solar brackets roof mount system from China weighs approximately 27 kilograms per square meter (a 1KW system is approximately 10 square meters).
