What are the Main Components of a Solar Energy System?

When we talk about solar power system, we may think the solar power system indicate just solar panel , but actually solar power system is more tha that , which consist of also other spare parts that involve in converting sunlight into electricity.

Befor you start with solar power system installation, it’s essential to have a clear knowledge of these different parts. you have to know well how these parts work and what role they play in the whole system. So this article will teach what are the main components of solar energy system.

what are these essential parts of a complete solar power system

you may wonder what are main components of a soalr power system. every solar panel system has some common components and also some optional components. you will read from some articles about solar panels systems , they will say the solar power systems have 4 components , some of them will tell you it has 5 or 6 components , but actually the numberts of solar power components dipend on types of solar system you choose. Generally speaking the core components of all installattions are solar panels, solar inverters , solar racking together with solar power system desconnect.

Solar panels:

These are devices that capture the sun’s rays and convert them into direct current (DC) electricity. They are usually installed on roofs, walls, or other surfaces that face the sun. The solar panel consists of many solar cells, and a solar system usually has a group of solar panels, called a solar array. There are different types of solar panels, such as monocrystalline, polycrystalline, and thin-film panels. The moncrystalline solar panels are the industry standard material for most new solar panel installations. Additional materials include glass , plastic, metal,and wiring. the common solar panels  available in market are 250 watt solar panle, 300watt solar panel, 450 watt solar panel. etc.

what are the types of solar panels system mounts

  • Monocrystalline silicon panels are made of a single crystal. They are the most efficient solar panels and the standard in the industry. However, they are also the most costly option.
  • Polycrystalline silicon panels are made of many silicon crystals joined together. They are a low-cost option and often used as parts of grid tied solar systems. However, they have lower efficiency than monocrystalline panels.
  • Thin-film solar cells are not as common as monocrystalline and polycrystalline. These solar cells use amorphous silicon and are the most flexible type of solar panel. These flexible solar panels can be a good choice if you need to install panels on a curved surface. You may find these panels as parts of off grid solar systems, such as RV solar panels or other installation situations that require light weight or have curvature. But generally, these panels have the lowest efficiency.


the solar power inverters are crucial components of any solar power system,it’s a device that converts the DC electricity from the solar panels into alternating current (AC) electricity, which is the standard form of electricity used by most appliances and devices. There are different types of inverters, such as string inverters, microinverters, and power optimizers.

the inverter will work throughout the whole lifetime of solar power system , it will habe a warranty of around ten years, while solar panel will have longer warranty time. normally around 25 years, so we will recommend you to invest more in inverter , better to choose big brand. as the solar inverter is most likely to bring issue.

Racking and mounts

these structured parts are used for holding solar system in place and allow them to tilt at an optimal angle. They are usually made of durable metallic materials to withstand rain, wind and snow. the racking mounts are usally divided into thre types based on the mount method,including roof mounts, ground mounts, and pole moounts.

what are the types of solar panels system mounts

  • roof mounts:This is the usual way of fixing a solar array to a building, such as a house, a small dwelling, or a business place. Roof mounts can also be used to put up hard solar panels on boats and vehicles, such as RVs and vans.
  • ground mounts: A solar array is fixed on concrete piers near the ground for stability using basic ground mounts. Panels are set at a constant angle but can be changed by hand as seasons vary. You can choose this option if you don’t have enough roof space. However, ground and pole-mounted panels need a lot of land space. So, this installation is not usually used for homes and is more popular in business or farming settings.
  • pole mounts:This is a rare type of mounting that attaches a solar array to a pole, fixed into the ground by concrete. Pole mounts lift panels higher than normal ground mounts and sometimes have tracking systems that adjust the solar panels automatically to get the best sunlight during the day and year.


the solar batteries are not essential components for solar power system, which are designed for store the energy for later use. solar batteries work as devices that can store the power generated during the day, the stored power can be used through the night when there is no sunlight. You can also use battery bank to store large capacity of power.

The batteres can also keep extra power for a long time for emergency if your system generates a lot of energy. This kind of solar power arrangement is called a hybrid system, and if you’re thinking about this option, it’s better to design a hybrid system from the start. After installation, it’s not always simple to put a battery to a system that is connected to the grid.

The battery may not be necessarty if you use grid-tied solar power system, as in the evening the gird-tied system can pull energy from electricity grid, But it will be especially useful for off-grid systems or grid-tied systems with backup power. There are different types of batteries, such as lead-acid, lithium-ion, and flow batteries

Charge controller

This is a device that regulates the voltage and current from the solar panels to the batteries. It prevents the batteries from overcharging or undercharging, which can damage them or reduce their lifespan. There are different types of charge controllers, such as pulse width modulation (PWM) and maximum power point tracking (MPPT)

Power meter

This is a device that measures the amount of electricity produced by the solar panels and consumed by the loads. It helps you monitor your system’s performance and efficiency. It also allows you to sell the excess electricity to the grid if you have a net metering agreement with your utility company

In Conclusion:

the solar power system consist of a series of common and also optional components , when you are doing an installation of solar power system, a solar kit can be a great option. you can also contact BESTSUPPLIERS.COM to have professional solar power equipment kit advice from solar system experts.
