1. What is a solar array?

A solar array is a collection of multiple power-generating solar panels grouped together and is the most important part of a solar panel system. Solar panels convert sunlight into electricity by collecting it. Solar arrays, also known as solar arrays, are used to meet the energy needs of large residential and commercial buildings.

2. What makes up a solar array system?

Installing a solar array at home often requires solar panels, electrical wiring, and for solar array systems that are connected directly to the grid a power inverter and net metering, which helps produce electricity for home use and transmission to the grid.

3. How does a solar array work?

When sunlight hits a solar panel, photons are absorbed by the semiconductor material in the solar panel. Electrons absorb the photons and move away from the nucleus in one direction. Because there is a design to the originals, this creates a controlled electric current.

As the current flows, the metal plates on the side of the solar cell absorb the electrons and transfer them to the lines in the solar array. This is then transferred to the power inverter, which converts the direct current generated by the solar cell in the panels into alternating current.

4. Major solar inverters:

Grid-tie inverters: solar arrays work when the home’s devices that need electricity at the time are prioritized, and then the excess power is transferred from the home to the grid. The net metering will track and record the amount of power output from the solar array as well as the amount of power recovered. Connected to the grid with a hybrid system, it is able to store power for later use. In the future, the power can be used despite bad weather.

(1) String Inverter: A string inverter is a series circuit in which solar panels are connected together by wires. It mainly converts the DC power from the solar panels into AC power.

(2) Micro inverter: It converts DC power into AC power at the power source. Connect it with each microinverter to form a combined AC output.

Solar Optimizer: When one of the solar panels is damaged, it affects the overall power of the other solar panels. A power optimizer is needed to isolate the damaged solar panels.

5. Solar array installation process:

(1) Consultation and on-site evaluation: Consult the professionals on the relevant issues, and then the solar company will evaluate our monthly electricity bill and the location where the installation needs to be carried out, mainly depending on the shape of your home’s roof, area and sunshine conditions.

(2) Conducting the design as well as permitting by the relevant authorities; based on the information gathered, the people from the solar company will design the best size solar array for you. Your installer will then submit the installation plan to the local building department and utility company for approval.

(3) Installation of solar panels: The solar company people will install the panels based on the approved design, which usually takes one to three days.

(4) Final Inspection: The solar company conducts a final check with the local utility company to obtain an operating permit.

6. How do I determine the direction and location of the solar array installation and the number of solar panels?

(1) The direction in which the solar array is installed is extremely important. For example, if you are in the northern hemisphere, a solar array facing south will be better than one facing north, west or east. This is because it will receive more hours of light and thus produce more electricity.

(2) We commonly install solar arrays on rooftops because rooftops tend to have more free space. However, if you have ample ground location and sufficient off light, ground mounted solar arrays are not a bad idea. If you need to install solar arrays, you also need to consider your home location.

(3) The number of panels to be installed often depends on your demand for electricity, as well as the size of your roof or ground, and the local climate and light hours.

7. The need to install a solar array

(1) Although the first installation of solar panels is costly, over time, as it saves a lot of energy consumption, the cost of the entire solar array will be substantial, the rate of return will increase, a significant savings in household expenses, for most families, it is a that is economical and affordable investment.

(2) Solar panels usually have a long service life, and rarely need maintenance, thus ensuring its reliability and durability.

(3) With the research and development of renewable energy sources, photovoltaic power generation is increasingly becoming an essential part of our lives. Installing solar panels is an environmentally friendly and practical way to reduce dependence on the traditional power grid as well as reduce greenhouse gas emissions, which is beneficial to our ecosystem.
