Complete List of Photovoltaic System Kit

The solar energy sector is growing considerably everywhere. Whether to save on electricity bills or to adopt more sustainable attitudes, investors are increasingly interested in this technology for generating electricity. But to produce electricity, the complete photovoltaic kit must be installed.

Solar energy is generated by capturing the rays which penetrate the cells of the plates and are converted through the photovoltaic effect. The solar energy kit consists of photovoltaic panels and other equipment that generate electricity to power homes, businesses, industries, and rural properties.

However, the complete photovoltaic kit must be appropriately installed on the property to ensure efficiency and quality in your solar energy system. I will talk about all the components of this kit and how each one should be used. Check it out, and happy reading!

What is a complete photovoltaic kit?

The photovoltaic kit comprises solar modules and other equipment that can generate electricity by capturing sunlight. It is acquired without installation labor and varies in size and type according to the purpose and location of implantation.

Solar kits feed any demand for electrical consumption, from pumping systems to homes and industries. When installed, they become photovoltaic systems that can be connected to the grid (On-Grid system) or isolated (Off-Grid).

What are the components of these kits?

Solar power kits are much more than just solar modules. According to the purpose of energy use, several other components are necessary to capture and generate electricity. Next, let's separate the components that make up the complete photovoltaic kit.

Solar panels

It is the set of solar modules, considered the heart of the system, installed on the roof of buildings or the ground. These are responsible for capturing and converting sunlight through their photovoltaic cells. When hit by solar radiation, the electrons in the cells generate electric current. The size and number of solar panels to be purchased will depend on the installation location and energy demand.

Interactive inverter

It is considered an essential part of the residential solar energy system since it is the equipment responsible for inverting the energy generated by the solar panels into electrical energy suitable for use, that is, from direct current to alternating current. In addition, this component sends surplus energy to the electrical grid (On-Grid system) or to the battery bank (Off-Grid system).

Junction box or string box

The equipment protects solar panels against network problems and other types of electrical faults. In repair cases, they also function as an access key for turning off the photovoltaic system.

Support structures

These are the rails and other equipment needed to fix the solar panels on the roof of buildings or the ground, supporting the photovoltaic modules.

Cabling

It is the set of cables and connectors used to make the electrical connection between the kit's components. The types of cables will depend on the solar modules chosen to compose the photovoltaic system and the distance between the components. There are cable models that protect against faults and short circuits.

Battery bank

This component serves to store the energy generated during the day and supply consumption when there is no incidence of sunlight. The battery bank makes up the Off-Grid system.

Charge controller

This equipment is responsible for managing the charging of batteries to avoid overcharging and wasting energy. Measuring battery voltage controls the intensity of the current passing through it. And as it approaches its maximum capacity, the controller decreases the current intensity. The main features of the charge controller are:

• Reverse current protection;
• Discharge control;
• Temperature compensation;
• System monitoring.

What are the existing types of photovoltaic kits?

There are a few main types of photovoltaic kits. Rural solar energy kits pump water from cisterns and wells in different versions. The simplest ones contain a module and the pump, which operates in direct current and does not need an inverter. There are still kits with a storage system with boards, a battery bank, and a charge controller.

The solar irrigation kit is larger and more complex than the water pumping kit, generating more energy. It has many modules, so it needs support structure and cabling and, in some cases, even components for energy storage.

Solar energy kits for lighting are also composed of LED lamps, photovoltaic panels, charge controllers, and batteries. They are made to be used at night and in residential applications, such as garden lights, in commercial projects, and for public lightings, such as solar poles.

On the other hand, residential solar energy kits are the most complex and have solar panels, an interactive inverter, a string box, cabling, a support structure, and, in some cases, an Off-Grid system, battery bank, and charge controller. In addition, there are photovoltaic kits for air conditioning and showers that are reduced versions and are intended to supply only the electricity consumed by the respective equipment.

How much does a complete photovoltaic kit cost?

A complete photovoltaic kit varies in price depending on the number of solar panels you have. The small ones, with six photovoltaic modules, cost an average of $3k. Medium-sized kits, with 16 solar panels can cost around $10k+. The larger kits, with 32 modules, are worth around $20k+.

Despite being considered a high investment, the cost-effectiveness of the solar energy system is a great advantage. It is estimated that, with the use of the kit, electricity bills may be reduced by up to 95%. Photovoltaic kits must be purchased from companies specializing in solar energy.

Therefore, a complete photovoltaic kit is essential to ensure the best efficiency in producing electricity for your property. Solar energy is a way to save considerably on your electricity bill, in addition to being a sustainable way to consume electricity. For this, look for a qualified company with experienced professionals and ensure more durability and safety for your photovoltaic system.
