What are Solar Panel Kits? Get an understanding of what solar kits are, what they’re for, and why you should or should not consider buying one.
Maybe you’ve heard of solar panel kits, but you don’t know exactly what they are and how they’re different from solar installations. Well, they are, kind of. Here’s what you need to know about solar panel kits, installing them, and the pros and cons of them.
What is a Solar Panel Kit?
A solar panel kit is a pre-packaged set of components that make a complete, functional solar system. Solar panel kits are designed for different purposes, from powering your house or business to powering an outlanding vehicle’s electric needs to even powering a remote water pump for a cow trough on an expansive ranch. However, they all share one thing in common, they should come with everything you need to harvest solar energy, use it, and in some cases store it in batteries.
Each component of a solar panel kit can be bought separately and put together to create a solar panel system. But, the concept behind a solar panel kit is that the company that offers it has done all the preparation work in assembling the proper components that will work together, and the user shouldn’t have to worry about determining whether the components are compatible during assembly. Instead of a professional installation, the target buyer is often a DIY (do-it-yourself) person.
Some solar panel kits are scalable. This means that you could add more solar panels to the system in the future to boost solar power output.
What are the Main Components of Solar Panel Kits?
All solar panel kits include some of the same basic components, like solar panels and wiring to help you harness and use solar energy. Beyond that the components vary based on the type and purpose of the kit. These are the components in most solar panel kits:
1. Solar Panels (Photovoltaic Modules):
These are the primary components of a kit that capture sunlight and convert it into direct current (DC) electricity through the photovoltaic effect. Solar panels are made up of multiple photovoltaic cells connected together. Some basic kits only contain the solar panels and wires to connect them to a battery or a device, like a pump, for direct use.
2. Charge Controller:
A charge controller is needed in kits with energy storage to charge batteries. It regulates the voltage and current coming from the solar panels to ensure that the batteries are not overcharged. The charge controller helps extend the lifespan of the batteries and prevents solar energy system loss.
3. Battery Bank:
In off-grid solar systems, a battery bank stores excess energy generated by the solar panels for later use, especially during periods when sunlight is not available. The stored energy is used during the night or on cloudy days.
4. Solar Inverter:
The solar inverter converts DC electricity produced by solar panels and/or stored in the batteries into alternating current (AC) for in homes and buildings.
5. Mounting System:
Solar panel kits often include solar mounting equipment to secure the solar panels and other components in place. This could be a roof mount, ground mount, pole mount, or other mounting equipment, depending on the intended installation site and system design.
6. Wiring and Connectors:
The kit should include wiring and equipment to interconnect the various components of the system. The wiring and connectors are designed to handle the voltage and amperage of the other system components. Proper wiring is essential to the system’s safety and ensures the efficient flow of electricity between the solar panels, charge controller, batteries, and inverter.
7. Power Meter or Monitor (Optional):
Some, more advanced kits, like those designed to power a home or RV, will include a power meter or monitor to track the amount of electricity generated by the solar panels and consumed by connected devices. This helps users monitor their energy production and usage.
8. Electric Vehicle Chargers:
Some solar panel kits are designed to provide electric vehicle (EV) charging. They can be part of a grid-tied system, off-grid or hybrid system, or even designed as a stand-alone EV charger.
The components of a solar kit and their specifications vary widely based on whether the system is designed for residential, commercial, remote, or off-grid use. Before buying one it’s important to carefully review the contents of a specific kit to ensure it meets your energy needs and solar installation requirements.
What are the Different Types of Solar Panel Kits?
Solar panel kits are designed for different needs and applications. Here are some common types of solar panel kits:
1. Grid-Tied Solar Panel Kits:
These kits are designed for homes and buildings to connect to the electric grid.
They generate electricity when the sun is shining for use in the home or building they’re attached to and feed any excess power back into the grid.
Grid-tied systems are often designed for net-metering arrangements, allowing homeowners to receive credits for the excess electricity they generate. However, the local utility must offer a net-metering program.
These systems must usually be permitted and inspected before being connected to the grid.
2. Off-Grid Solar Panel Kits:
Off-grid kits are suitable for homes and buildings without access to the electric grid.
They are generally designed to meet all of the building’s energy needs and include batteries to store excess energy generated during sunny days for use during periods without sunlight like night and during cloudy days. As such, they’re usually designed to be larger than a grid-tied solar system.
3. Hybrid Solar Panel Kits:
Hybrid solar kits combine features of both grid-tied and off-grid systems.
They can operate connected to the grid but also have solar battery storage for backup power during grid outages.
Some hybrid solar kits are also designed to incorporate other forms of renewable energy, like wind.
These systems must usually be permitted and inspected before being connected to the grid.
4. RV/Marine Solar Panel Kits:
These kits are designed specifically for recreational vehicles (RVs), overlanding, and marine applications.
They are easier to put together as a DIY solar project and are portable and compact, providing a source of power for appliances and devices in mobile settings. Some may fold out when the vehicle is stationary.
5. Portable Solar Panel Kits:
Portable solar kits are small, lightweight and are usually used to power smaller things, like smart devices and speakers. They may have flexible solar panels and are suitable for picnicking, car camping, backpacking, hiking, or other outdoor activities.
They often come with foldable or flexible solar panels for easy transportation.
6. Residential Solar Panel Kits:
These kits are customized for residential use, providing homeowners with a solar solution to generate electricity for their homes.
They should include all the necessary components, such as solar panels, inverters, and mounting systems.
These systems must usually be permitted and inspected before being connected to the grid.
7. Commercial Solar Panel Kits:
Similar to residential kits, commercial solar kits are designed for businesses and larger-scale applications.
They are customized based on the energy needs and available space of the commercial property.
These systems must usually be permitted and inspected before being connected to the grid.
8. Remote Solar Kits:
These kits use solar energy to provide power in remote locations. They’re used to power things like water pumps, street construction signs, weather stations and more. They’re sized for the appropriate need and are often DC-based solar kits.
When choosing a solar panel kit, beyond considering the applications, it is important to consider factors such as your energy needs, local regulations and permitting requirements—if installing on a building, as well as your budget, and whether you want a system tied to the grid or off-grid solar. Consulting with a solar installer near you can help you decide if you can take on such a project or not, and also help you select the most suitable kit for your specific requirements.
