The PV Solar Panel power System installation guide is helpful for those who are new to this green technology and want to explore and embrace it. However, the goal of this installation guide is to provide deep information on solar panel power systems, how they work, and how to connect all the components of the Balance of the system (BoS) of the PV system. The Balance of the system (BoS) of the PV system is all the components that convert the DC power to a useful AC power, to be used further to power up appliances. Here's a quick guide on Solar Panel Installations that will provide you with some background knowledge and crucial topics
Solar Mounting System
The first step in which Solar Panel Installations evolve is the mounting system. Solar mounting is the process of installing photovoltaic solar panels on a roof or other structure. Depending on the cost and size of the solar panel, it can be done in a variety of methods. Solar panel mounting is the system in which first you have to look into account your mounting system preference. This system has many classifications, pole mounting, bracket mounting, ground mounting system, etc. Each mounting system has its features, merits, and demerits. Before installing a PV Solar Panel Power system, it is necessary to have a proper understanding of the different types of these mounting systems and the most important thing is to choose the right type of mounting system by your needs and condition.
Tracking mount systems
Tracking mount systems track the sun’s radiations and allow the Solar Panel in the direction of the sun’s radiations throughout the day. Tracking mounts must be used to follow the sun's path as well as its rotation angle to get the most out of a ground-mounted Solar Panel Installation.
Solar Panel mounting Orientation
Solar Panel mounting azimuth between 20 Degrees to 45 Degrees offers your solar panels maximum exposure to sunlight and ultimately getting the maximum power throughout the day. The common myth found in guides is that the south-facing orientation roof azimuth towards the north latitude is the best orientation to get maximum solar exposure. However, to some extent, this is correct, because when putting a solar array on a racking system, whether it is the roof structure itself or the frame, one thing to consider is the latitude and orientation. However, many Android applications are available that help you figure out the maximum latitude fits to mount a solar panel.
Series and Shunt Connection
The Solar module has two terminals-labeled as Positive and negative ends. The positive (live wire) end of one Panel links to the negative (grounded) end of the other in a series ( one end common) wiring. Voltage adds up when configured in a series, when you connect two 12 V modules in series, you'll get 24 V on the output.
Furthermore, in shunt or parallel connection, the PV Panels connection is parallel to match its voltage to the rated battery bank voltage. However, the voltages in the shunt connection will remain the same. The wiring will be put in place so that the PV modules' positive terminals connect to the positive terminals of other modules, and likewise for the negative terminals.
One thing to remember when installing the PV Solar panels is to match the panel's rated voltage capacity to the battery bank's rated voltage. If there is a mis-frequency in these connections, the chances of DC damage will increase, i. Additionally, for this purpose, consult the solar panel services provider available to you.
To select the best batteries, you can consult different services providing companies like Solar Panel Costing, which provides you with the UK's best Solar Panel installation services in your city. A battery in a solar PV power system ensures that you have enough output power throughout the peak and off-peak hours.
While installing the battery the series and shunt connection should be considered accurate. The necessity of a battery charge controller is heavily addressed for this function.
The Charge controller will act as the charge regulator in the Solar PV System to sustain the live performance. It prevents the batteries from deep discharge or overcharge, as both will damage the battery badly.
When the battery gets overcharged by the solar module, the charge controller breaks the flow of current by disconnecting from the circuit. On the other extreme, when there is more load demand from the battery, the battery disconnects to prevent the battery from going into a deep discharge state.
Combiner Box and Surge Protection
The Live wire (+ve) and negative (-ve) ends are closed separately using strips inside the combiner box.
A Surge ( due to lightning) Protection device is introduced in the combiner box during an environmental (lightning) hit to defend against any potential electrocution, and hazardous DC loss.
The inverters' input is fed by the output of the electric control combiner box.
Grounding is necessary to protect against any natural surge event like lightning or any DC explosion shocks. When a Solar Power system functions in a high temperature and high humidity scenario, then the grounding prefers along with inverters. Grounding should be done properly while taking assistance from the experts.
For connecting each module wire is introduced. It acts as the medium of transferring energy between different modules. Remember that if you are using low-quality wire with a smaller thickness listed according to the Standard wire gauge chart, it will not sustain more energy than its rated capacity, it will burn and power breakdown occurs.
know that the larger the SWG (Standard wire gauge) dimensions, the smaller the thickness in mm.
The purpose of introducing the inverters along with the battery is for converting the DC power to the AC power and ensuring that the pulse of the AC signal is appropriate for the functionality and prevents voltage fluctuations and the Islanding effect in grid-tied systems.
Solar PV Sizing Depending upon Residential Load
Solar PV sizing for the residential apartments is done by precise calculations, like considering the KWh power house consumes per year, power rating of the PV panel itself produces, and rooftop size. However, In the UK, the sun peak hours vary from area to area but a maximum of 3-4 peak hours are enough for the solar panel to be worth it. But before installation, the best way is to take assistance from the service providers which have better knowledge of it. You can partner with Solar Panel Costing, which provides the best consulting and services in the UK.
Flow Diagram of Solar PV Power System
Solar PV power systems generate useful carbon neutrality green energy. To make this happen, solar panels generate electricity by absorbing the sun's rays and converting them into direct current (DC). This DC is then converted into alternating current (AC) using inverters. The AC power is then sent through the grid and used for various purposes such as charging batteries for use in appliances.
A solar power system can be an extremely beneficial resource for your home. Solar power systems are meant to encourage you to cut your carbon footprint, save money on monthly bills, and also provide a lot of other advantages. However, many people have no idea how to begin installing their solar panel system. Hopefully, this article helps you to understand the key points of solar power system installation.
