How does a solar PV system work?

To have a functional solar PV system, you need to wire the panels together to create an electrical circuit through which current will flow, and you also need to wire the panels to the inverter that will convert the DC power produced by the panels to AC power that can be used in your home and sent to the grid. In the solar industry.

Should I connect my solar PV system to the grid?

Connecting your solar PV system to the grid allows you to take advantage of the FIT, which gives you a fixed amount of money for each kWh of electricity you generate. On top of these payments for energy generation, you also receive a sum of money for feeding any surplus energy into the grid.

What causes electricity to flow in a solar array?

It is this difference in charge that causes electricity to flow. Voltage is a measure of potential energy, or the potential amount of energy that can be released. In a solar array, the voltage is affected by a number of factors. First is the amount of sunlight (irradiance) on the array.

How to string solar panels?

Basic Rules for How to String Solar Panels 1 Ensure the Minimum and Maximum Voltage Are Within the Inverter Range#N#Do not allow the strings you are connecting to... 2 Ensure Strings Have Similar Conditions — or Connect Strings with Different Conditions to Different MPPT Ports#N#Once... 3 Advanced Considerations to Optimize Your Design More ...

How solar PV panels generate electricity?

How Solar PV Panels Generate Electricity. Solar photovoltaic (PV) panels use cells containing a semi-conductor material to capture the sun’s energy and convert solar radiation into electricity. The most commonly used semi-conductor material is silicon, which is an abundant natural resource found in sand.

What is a solar PV system?

A solar PV system usually comprises solar panels, an inverter, isolator switches, a PV-generation meter and cables. The more panels you can fit on your roof, the more expensive the system will be to purchase and install. But the more electricity you will produce.

Why are batteries used in solar PV systems?

Other reasons batteries are used in PV systems are to operate the PV array near its maximum power point, to power electrical loads at stable voltages, and to supply surge currents to electrical loads and inverters. In most cases, a battery charge controller is used in these systems to protect the battery from overcharge and overdischarge.

How does a PV cell work?

Most PV cells have two layers of semi-conductor material, one positively charged and one negatively charged. When light shines on the semi-conductor the electric field across the junction between these two layers causes electricity to flow, generating direct current (DC).

How many solar panels can I connect in a string?

The maximum number of solar panels you can connect in a string is determined by the maximum input voltage of your inverter or charge controller. You can find this value on the inverter datasheet.

What is a solar string inverter?

A string consists of solar panels wired in a series set into one input on a solar string inverter. If you have two or more solar panels wired together, that is a solar / PV array. String sizing refers to how many solar panels can and should be wired to an inverter for best results.

What is the difference between a solar array and a string?

To quickly recap, a solar array consists of two or more solar panels wired together, and a string refers to solar panels wired into one inverter input. The good news is you do not have to be an expert in these to avail of solar power.

What does stringing solar panels in series mean?

Stringing solar panels in series involves connecting each panel to the next in a line (as illustrated in the left side of the diagram above). Just like a typical battery that you may be familiar with, solar panels have positive and negative terminals.
