What is a Solar Power System?
Solar power systems are renewable energy systems that convert sunlight into electricity. They can be used to power homes, businesses, and entire communities.
Why Solar Power is Gaining Popularity
Go solar power, the renewable energy darling! This clean green electricity source has been blowing up more than a boombox at the beach.
And for a good reason – it just makes sense:
Cost savings over traditional power sources.
Saving some moolah is what originally drew people’s attention. With Uncle Sam giving tax credits and electricity bills shrinking more than your favorite t-shirt in the dryer, who wouldn’t be intrigued?
Plus, you get to stick it to the utility man by making your own power. Take that, The Man! Increased Energy Independence.
Solar provides off-grid havens of electricity for cabins, tiny homes and #vanlife adventurers living that gypsy dream. With batteries storing sunlight captured in the day, small solar systems can provide electricity on tap without any connection to the grid.
Off-grid solar also illuminates road signs, far-flung cell towers, and shelters in rural areas still waiting for power lines.
But it’s not just about the Benjamins. People care about leaving a healthy planet for our kids too. And nothing says “I love you, Mother Earth” like going solar.
Soaking up all that free sunshine is way better than polluting the air with fossil fuels. The Lorax definitely approves.
Availability of financing options
And get this – banks and investors are throwing money at solar like seagulls at a beach picnic. Apparently, they weren’t listening when their mothers said, “don’t invest in solar, you’ll put your eye out!”
Financial backing means going solar is more accessible than ever.
The cherry on top is that solar tech keeps improving like players leveling up in Fortnite. Panels are more efficient, batteries store more, and inverters have gotten hip to the jive.
This makes systems way better than when solar first had its groovy moment in the 70s.
Brief History of Solar Power Systems
We – humans – have used solar energy for thousands of years.
Early Applications of Solar Energy
- During the 7th century B.C., humans used sunlight to light fires with magnifying glass materials.
- During the 3rd century BC, Romans and Greeks used mirrors to harness solar power to light torches for religious ceremonies.
- Scientists and researchers used sunlight to power ovens for long voyages and produce solar-powered steamboats during the 1700s and 1800s
- In 1839, Edmond Becquerel discovered the photovoltaic effect, which produces a voltage when exposed to light.
- In 1883, a New York investor, Charles Fritts, created the first solar cell by coating selenium with a thin layer of gold.
Advancements In Solar Technology
- In the 1950s, the first practical solar cells were developed by Bell Labs. These cells were made from silicon and had an efficiency of about 6%. The technology was later used in space applications, such as powering satellites.
- In 1958 The Vanguard I satellite powered its radio communication with a single-watt solar panel.
- In the 1970s, the oil crisis increased interest in renewable energy, and the price of solar cells began to decrease. This allowed for the development of new applications for solar panels, such as powering remote homes and telecommunication equipment.
- In 1973, The University of Delaware created one of the first solar buildings, “Solar One,” which ran on a combination of solar thermal and solar photovoltaic power.
- In the 1980s and 1990s, technological advances led to an increase in the efficiency of solar cells, and the price of solar panels continued to decrease. Commercial concentrated solar power plants were first developed. This made it more feasible to use solar panels for residential and commercial applications.
Increase In Efficiency And Reduction In Cost
It’s no secret that solar panel technology has come a long way in recent years. In the past, solar panels were bulky, inefficient, and expensive.
This is just the history of the use of solar power at a glance. There is so much to the development of solar panels up to today, and more advancement is still being made.
But today, they are smaller, more efficient, and more affordable than ever.
This has led to a significant increase in the popularity of solar power systems as more and more users realize the potential benefits of these systems.
The efficiency of solar cells can reach up to 22%.
Also, the cost of solar panels has decreased significantly, making them more accessible to homeowners.
Solar panel Kits vs Solar power systems
Before we go deeper, let’s distinguish between solar panel kits and solar power systems.
Solar panel kits and solar power systems are two options for harnessing solar energy.
Here are the main differences between the two:
Solar Panel Kits
- This is a solar power system kit containing a bundle of solar panels and all the necessary components to install and operate the solar energy system.
- They are typically less expensive than full-fledged solar power systems.
- They are portable and can be used in multiple applications.
- They may be less efficient than full-fledged solar power systems.
Solar Power Systems
- A solar power system is a dedicated system that harnesses solar power.
- They involve more permanent installations, even if the panels may be portable.
- They are connected to your home, RV, or boat’s electrical system.
- They offer more value for a relatively little additional cost.
- They are more efficient and can generate more power than solar panel kits.
Both solar panel kits and solar power systems have different components.
Let’s simplify everything with a table comparing the components of both solar power kits and solar power systems.
|SOLAR PANEL KITS||SOLAR POWER SYSTEMS|
|Solar power system disconnects.||Solar panels|
|Charge controller||Solar inverter(s)|
|Solar Wiring and Cables||Solar racking|
|Mounting hardware||Charger controllers (optional)|
|Energy storage (optional)||Solar power meter (optional)|
|Solar Wiring and Cables|
|Solar power system disconnects.|
|Solar battery storage unit(s) (optional)|
Solar panel kits are portable and less expensive but may be less efficient and offer less value in the long run.
Solar power systems are more permanent, more efficient, and offer more value, but they are more expensive and less portable.
How Do Solar Power Systems Work?
Simply put, a solar power system consists of components that convert sunlight into usable electricity.
The major components include solar panels, charge controllers, inverters, and batteries.
Solar panels are made up of photovoltaic cells that convert sunlight into direct electricity (DC electricity).
When sunlight hits the solar panel, the photovoltaic cells absorb the energy and release electrons creating a current flow.
Solar charge controller
The charge controller prevents overcharging and undercharging, which can damage the solar battery.
It also helps to maintain a consistent charging voltage.
The inverter converts the direct current (DC) electricity the solar panels produce into alternating current (AC) electricity used in most homes.
Most home appliances require alternating current and solar panels produce direct current.
Solar battery storage systems allow you to store the excess electricity from the solar panels for later use.
This can be especially useful in off-grid home solar power systems or hybrid solar panel systems, where the solar power system is not connected to the grid.
An electrical panel is an important component of a solar power system as it distributes the AC electricity generated by the inverter to your home’s appliances and other electrical devices.
Types of solar power systems
Now that you have a basic understanding of the history and components of a solar power system let’s look at the different types of Solar power systems available.
The three main types of Solar power systems are grid-tied, off-grid, and hybrid.
Grid-tied solar power system
Grid-tied solar panel systems are connected to the electrical grid.
So, any excess electricity generated by the solar panels can be sent back to the grid, and you can also draw electricity from the grid when needed.
A grid-tied system is the most common type of solar panel system and is ideal for homeowners who want to reduce their electricity bills but still have access to grid-supplied electricity.
Pros of grid-tied solar power systems:
- Low upfront costs
- Offer high bill savings
- Can receive credits for excess energy production
- Great for those who don’t have the room or financing to install a solar system big enough to cover 100% of their energy usage
- Can continue to pull electricity from the grid if needed
Cons of grid-tied solar power systems:
- It can’t be used for backup power when the grid is down.
- Keep you yoked to the utility company.
- Automatically shut down during a grid outage and turn back on when power is restored if a grid failure causes a power loss.
Off-grid solar power system
Off-grid solar panel systems are not connected to the electrical grid.
This means that the electricity generated by the solar panels is used to power your home, and any excess electricity is stored in a battery storage system for later use.
The off-grid system is ideal for remote homes or cabins that are not connected to the grid.
Pros off-grid-tied power systems:
- Allows you to be completely independent of your grid supplier
- It does not rely on any other power source except the sun itself.
- No need to pay electricity bills
- No need to worry about power outages
- It can be used in remote locations where there is no access to a utility line
- Can be customized to meet specific energy needs
Cons off-grid-tied power systems:
- More expensive than grid-tied systems due to the need for batteries and other equipment
- Requires more maintenance than grid-tied systems
- May not be able to generate enough power to meet all energy needs
- It may require a backup generator when there is not enough sunlight.
- May not be eligible for net metering programs
Hybrid solar power system
These systems are a combination of grid-tie and off-grid systems.
They are connected to the power grid and equipped with their own battery storage system.
Hybrid systems are the most flexible option available, allowing storing excess energy for use later and providing power during a grid outage.
Pros of hybrid solar power system:
- Provides an uninterrupted power supply
- Can store excess solar energy for later use
- Can reduce your electricity bills
- Can help reduce the demand for traditional sources of energy
- Can provide a power backup system
- Can work more efficiently and sustainably than traditional generators
- Can be less expensive to install and maintain than an off-grid system
- Can be a great way to be in control of your power supply
Cons hybrid solar power system:
- Higher upfront system costs
- High cost of batteries
- Payback time is very high in years
- Installation cost is high
- More space is required to install the entire system
- It does not have a grid isolation device, which means it cannot power your household in case of a blackout
- Requires more space than traditional systems
Components of Solar Power System
When we discussed how these systems work, we mentioned the components of a solar power system just bypassing.
Here we shall discuss each component in detail.
Note that your system may include only some components we will discuss here.
For instance, if you have a simple off-grid system, you may only require key components such as panels and batteries.
However, a big business may require a more complicated system with almost all the components we shall discuss here.
The first component is solar panels. Solar panels convert energy from the sun into usable DC current electricity. Solar panels are made of photovoltaic cells connected together to make a solar panel.
Solar panels are the most visible part of a solar power system. We shall have a separate article detailing how solar powers work. There are different types of solar panels.
The most common types of solar panels are monocrystalline, polycrystalline, and thin-film solar panels.
Others include bifacial solar panels, concentrated solar panels, and building-integrated photovoltaics (BIPV).
Monocrystalline Solar Panels
These solar panels are made from a single crystal structure, typically silicon. They have a high-efficiency rate and are known for their sleek black appearance.
Monocrystalline panels perform well in high-temperature conditions and are often used in residential and commercial installations.
These panels have an efficiency range of 15-25%.
Polycrystalline Solar Panels
These solar panels are made from multiple silicon crystals, which give them a distinct blue color.
Polycrystalline panels are less expensive to produce than monocrystalline panels but have a slightly lower efficiency.
They are commonly used in residential and commercial applications. Polycrystalline solar panels have an efficiency range of 13-16%.
Thin-Film Solar Panels
Thin-film solar panels are made by depositing thin layers of photovoltaic material onto a substrate, such as glass or metal.
They are flexible and lightweight, making them suitable for various applications, including curved surfaces and portable solar panels.
However, thin-film panels typically have lower efficiency compared to crystalline silicon panels. Thin-film solar panels have an efficiency range of 10-13%.
Bifacial Solar Panels
Bifacial panels can capture sunlight from both sides, maximizing energy production.
These panels have a transparent back sheet that allows sunlight to pass through and reflect off the surface they are installed on.
Bifacial panels can be monocrystalline or polycrystalline. Bifacial solar panels are useful in sun-tracking systems, swimming pool glass installations, or roofing pavilions, pergolas, and gazebos.
The efficiency of bifacial solar panels depends on the type and condition of the cells used, but they can have between 22-23% efficiency.
Bifacial panels are far more efficient in capturing sunlight than mono-facial panels and can increase energy generation by as much as 30%.
Concentrated Solar Panels
Concentrated solar panels use lenses or mirrors to concentrate sunlight onto a small area.
They are commonly used in utility-scale solar power plants and require sophisticated tracking systems to follow the sun’s movement throughout the day.
Concentrated solar panels can achieve high efficiency but are more complex and expensive than traditional ones.
These solar panels can reach efficiencies of up to 46%.
Building-Integrated Photovoltaics (BIPV)
BIPV refers to solar panels that are integrated into building materials, such as solar roof tiles, solar shingles, solar windows, or solar facades.
These panels blend with the architecture of the building and serve both as a power source and a building element.
They are less efficient than traditional solar panels because they are often designed to blend in with the building’s architecture rather than maximize energy production.
Solar charge controller
When batteries are part of the system, a charge controller is used to regulate the charging process and prevent overcharging or discharging of the batteries.
- The three main types of charge controllers are:
- PWM (Pulse Width Modulation) Charge Controllers
- MPPT (Maximum Power Point Tracking) Charge Controllers
- Solar Hybrid Charge Controllers
We also have the following:
- Chant Controllers
- Series Controllers
PWM (Pulse Width Modulation) Charge Controllers
PWM charge controllers are the most basic and affordable type. They work by rapidly turning the solar panel’s current on and off, effectively regulating the amount of charge sent to the battery.
PWM controllers are suitable for small to medium-sized solar systems and are often used in off-grid applications.
They are less efficient compared to MPPT controllers but are still widely used.
MPPT (Maximum Power Point Tracking) Charge Controllers
MPPT charge controllers are more advanced and efficient than PWM controllers.
They use a sophisticated algorithm to track and maximize the power output of solar panels.
MPPT controllers can convert the excess voltage from the panels into additional charging current for the batteries, resulting in higher charging efficiency.
They are particularly beneficial in larger solar systems and installations with varying weather conditions or shading.
Solar Hybrid Charge Controllers
Solar hybrid charge controllers combine the functionality of a charge controller with an inverter solar power system.
They are designed for hybrid solar power systems, including solar panels, wind turbines, or other renewable energy sources.
These controllers can manage the charging process from multiple sources and ensure optimal power generation and storage.
Shunt Charge Controllers
Shunt or diversion charge controllers are used in certain solar systems where excess energy needs to be redirected or dissipated.
These controllers are typically used in off-grid systems with battery banks that may become fully charged.
When the batteries are fully charged, the shunt controller diverts the excess energy to a resistive load, such as a water or space heater, rather than overcharging the batteries.
Series Charge Controllers
Series charge controllers are a less common type of charge controller that operates by connecting the solar panels in a series configuration.
This type of controller is used in systems where the solar panels have different voltages, such as mismatched or older panels.
Connecting the panels in series increases the voltage to match the battery bank voltage, allowing for efficient charging.
But series charge controllers can have limitations in terms of flexibility and may not be as widely available as PWM or MPPT charge controllers.
Solar panels produce DC electricity, but most household appliances and the electrical grid operate on alternating current (AC).
An inverter converts the DC electricity from the panels into AC electricity.
The inverter also manages the flow of electricity between the solar panels, battery storage, and the grid. Different types of solar inverters include
String or central inverters are the most common type in residential and commercial solar installations.
They are connected to multiple solar panels wired in series, forming a string.
String inverters convert the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity that can be used by household appliances and fed into the electrical grid.
They are cost-effective and suitable for systems with unshaded and consistent solar panel arrays.
Microinverters are installed on each solar panel in a solar system. Unlike string inverters, microinverters convert the DC electricity to AC electricity directly at the panel level.
This allows for the independent operation of each panel, optimizing the energy output even if some panels are shaded or affected by different orientations.
Microinverters can improve the overall system performance, especially in installations with complex roof configurations or shading issues.
They also offer enhanced monitoring capabilities at the panel level.
Power Optimizers with Central Inverter
Power optimizers are devices installed on each solar panel, similar to micro inverters.
They optimize the power output of each panel and then send the DC electricity to a central inverter for conversion into AC electricity.
This hybrid system combines the benefits of panel-level optimization with the cost-efficiency of a central inverter.
Power optimizers can mitigate shading effects and monitor each panel’s performance.
It’s worth noting that there are other specialized types of inverters used in specific applications, such as:
Hybrid inverters, including energy storage and batteries, are designed for solar power systems.
These inverters can manage both the solar panels’ energy production and the charging and discharging of the batteries, providing backup power during grid outages or optimizing the self-consumption of solar energy.
Grid-tie inverters are used in grid-connected solar power systems.
They synchronize the AC electricity produced by the solar panels with the utility grid’s voltage and frequency, allowing for the excess energy to be exported to the grid or for the grid to supply power when needed.
In some solar power systems, batteries store excess electricity generated during the day for later use.
These batteries store DC electricity and provide power when the solar panels are not producing electricity, such as at night or during cloudy weather.
There are four main types of solar batteries: lead-acid, lithium-ion, flow, and nickel-cadmium.
Lead-acid batteries are the most common type of solar battery. They are relatively inexpensive and have a long lifespan. However, they are also heavy and require regular maintenance.
Lithium-ion batteries are the most expensive type of solar battery but are also the most efficient and have the longest lifespan. They are also lighter and require less maintenance than lead-acid batteries.
Flow batteries are a newer type of solar battery-less common than lead-acid or lithium-ion batteries. They are more expensive than lead-acid batteries but have a longer lifespan and are less sulfation prone.
Nickel cadmium batteries
Nickel-cadmium batteries are a type of solar battery that is no longer as common as lead-acid or lithium-ion batteries. They are more expensive than lead-acid batteries but have a longer lifespan and are less sulfation prone.
Solar Mounting system
Solar panels must be securely mounted on rooftops, ground mounts, or other structures. The mounting system ensures proper alignment and stability of the panels.
Solar Wiring and Cables
Various wiring and cables connect the solar panels, inverter, batteries (if used), charge controller, and electrical panel. These ensure the safe and efficient transfer of electricity within the solar power system.
The AC electricity generated by the solar panels or supplied by the grid is sent to the electrical panel (also known as a breaker box or distribution board). The panel distributes the electricity to various circuits in your home or building.
Solar power system disconnects.
Allow you to turn off the solar power system for maintenance or safety reasons.
A net meter is typically installed if your solar power system is connected to the electrical grid. It measures the electricity your solar panels generate and any excess electricity sent back to the grid.
The net meter allows for net metering or selling excess electricity to the utility company.
Some solar power systems include monitoring equipment that tracks the system’s performance, providing information on energy production, system health, and potential issues.
Solar efficiency refers to the percentage of incoming sunlight a solar panel can convert into usable electricity.
The higher the efficiency, the more electricity the panel can produce from the same amount of sunlight. The following factors affect solar panel efficiency:
- Photovoltaic cell efficiency refers to the solar cells’ efficiency in a photovoltaic system, which is determined by the cell type and design.
- High-efficiency solar panels can reach as much as nearly 23%.
- Total panel efficiency: This is based on cell type, layout, and size. The most efficient solar panels available today are approximately 23% efficient.
- Latitude and climate: The efficiency of a solar panel is also influenced by the location and climate in which it is installed.
- Amount of light reflected away from the cell’s surface: The amount of light reflected away from the cell’s surface can affect solar panel efficiency.
- The intensity of the sun: The sun’s intensity can also affect solar panel efficiency.
- Amount of cloud cover: Cloud cover can reduce the amount of sunlight that reaches a solar panel, affecting its efficiency.
- Heat build-up: Heat build-up can also affect solar panel efficiency.
Improving solar panel efficiency is a key research goal and helps make solar technologies cost-competitive with conventional energy sources.
How is solar efficiency measured?
Solar efficiency is measured by a solar panel’s amount of sunlight converted into electricity.
The higher the efficiency, the more electricity is produced from the same amount of sunlight.
To measure solar efficiency, you need to know the following:
- The amount of sunlight that hits the solar panel (in watts per square meter)
- The amount of electricity that the solar panel produces (in watts)
- The area of the solar panel (in square meters)
Once you have this information, you can calculate the efficiency using the following formula:
Efficiency = (Power output / Sunlight intensity) * 100%
For example, suppose a solar panel with an area of 1 square meter produces 100 watts of electricity when exposed to sunlight with an intensity of 1000 watts per square meter.
In that case, its efficiency is 10%.
Efficiency = (100 watts / 1000 watts per square meter) * 100% = 10%
Solar efficiency is important because it determines how much electricity a solar panel can produce.
A higher-efficiency solar panel will produce more electricity from the same amount of sunlight, saving you money on your electricity bill.
Solar panel manufacturers are constantly working to improve efficiency, and new technologies are always being developed.
So, solar efficiency is expected to continue to improve.
