Photovoltaic panel full coverage construction plan

Should a general contractor install a solar PV system?

A general contractor may face a choice between using an electrical subcontractor or a solar subcontractor to install the PV system. A good solar contractor will have the expertise in solar PV systems plus qualified electricians on staff.

What is a photovoltaic system?

photovoltaic system (or PV system) is a system which uses one or more solar panels to convert sunlight into electricity. It consists of multiple components, includ-ing the photovoltaic modules, mechanical and electrical connections and mountings and means of regulating and/or modifying the electrical output.

What is preliminary solar energy site screening?

preliminary solar energy site screening provides a rough estimate of the solar resource, energy production, and cost of a PV system. It also provides information for a go- or no-go decision to proceed further in the procurement process.

Can a PV system be installed on a roof?

Nevertheless, it is possible to install PV modules on all roof types. If the roof will need replacing within 5 to 10 years, it should be replaced at the time the PV system is installed to avoid the cost of removing and reinstalling the PV system.

Can a PV system be installed on an inefficient building?

A PV system installed on an inefficient building is expensive and may pose a number of substantial risks. The PV system will need to be larger to cover the wasted and inefficient use, which will significantly increase the size and cost or the system, lengthen the payback period, and could potentially prevent the system from being profitable.

What is a photovoltaic module?

Operation & Maintenance 1.1 Photovoltaic (PV in short) is a form of clean renewable energy. Most PV modules use crystalline silicon solar cells, made of semiconductor materials similar to those used in computer chips. Thin fi lm modules use other types of semiconductor materials to generate electricity.
