The solar power system is a complete setup ideal for home and commercial places, which helps in producing electricity by utilizing solar energy (sunlight). A solar power system is made up of solar panel (which absorbs sunlight), inverter (which converts DC electricity into AC), mounting structure (which holds the panels in place), batteries (helps to store the extra power generated), grid box and balance of systems (wires, nuts).
In other words, a solar power system is composed of numerous photovoltaic (PV) panels, inverter (a Dc to AC power converter), and a rack system that holds the PV panels in place (solar PV panels on the roofs of homes and businesses generate clean electricity by converting the energy in sunlight). Solar power system comes in 1 kW, 3kW, 5kW, 10kW, and several other capacities. It is a good choice for those who want to reduce their electric bills and their carbon footprint.
As the prices of electricity are rising, people across the world looking for renewable energy sources for their power, or electricity needs. Solar energy has now become a popular renewable energy source because of its cost-effective price and improving efficacies. And for this reason, the solar system for home has stepped forward in the market with its great features.
On-Grid Solar System
The on-grid solar system or Grid-tied solar system is a kind of solar system that generates current only when the utility power grid is available. In other words, the on-grid system is a solar system that generally works with the grid. Saving the electricity bill is the prime purpose of installing an on-grid solar system.
The on-grid solar power system consists of Solar Photovoltaic modules / Panels, DC-AC grid-tied solar Inverter and Installation Kit (includes mounting structures, ACDB, DCDB, A.C, D.C wire, Connectors, lighting arrestor, earthling cables).
The foremost benefit of installing an on-grid solar system for home is a cost-effective solution, which helps to pay for such systems by offsetting utility bills in 3-8 yrs. In addition to this, there are some other advantages of the on-grid solar system, including:
• Zero electricity bills (consumer has to pay only for the surplus electricity he consumes because the solar power system is connected to the grid only).
• Easy maintenance (on-grid solar power system has the least number of parts along with simple installation or fitting).
• Passive income generation (with connection to the grid, the consumer can charge for the surplus electricity he has generated, which is not only beneficial in reducing your electricity bills but also helps to avail the cost benefits for the excess electricity generated).
• Provides you with at least 5 years' payback time and free electricity for the next 20 years.
Moreover, the on-grid solar system is simple enough that anyone can install it by himself. The on-grid solar system price is affordable that anyone can purchase it by investing at pocket-friendly prices.
Off-Grid Solar System
The off-grid solar system is a popular type of solar power system with backup, which works both day and night. During the day time, solar panel charges the battery to run the home appliances with the use of DC, and at night or cloudy weather days when the sunlight is not available, inverter runs your home appliances (Air Conditioners, Cooler, Television and submersible pump, etc.) using the battery power or AC current.
The off-grid solar system allows you to store your solar power in batteries for future use, especially when the power grid goes down or if you are not on the grid. Hybrid systems are capable of providing power to balance the grid power whenever the sun shines, which enable to send excess power to the grid for later use.
The utmost benefit of using an off-grid solar system is to provide power for your critical loads when the power grid becomes down. An off-grid system is more prevalent that comes with a power backup and works independently of the grid.
Benefits of using off-grid solar system:
• Works as a self-sustainable system that can work independently and not depending on the grid
• Helps in avoiding power outages, which may occur without any warning
• Helps in generating enough power that can be stored and used at night or when the power grid is down
• Reduces electricity costs (fossil fuels are still the world's primary energy source)
• Easier installation facilities
• Best alternative for remote areas where there is no power access from the grid
• Keeps the environment clean and green
Hybrid Solar System
The hybrid solar system is another type of solar power system that generates power or electricity supply in the same way as the common grid-tie solar system does. The only difference of a hybrid solar system is that such a system uses batteries to store energy for later usage. A hybrid solar system can operate as backup power, and it is possible because of the ability to use the maximum amount of stored energy (uses this energy during a blackout which is similar to a UPS system).
The term ‘hybrid solar system’ refers to a combination of battery storage and solar systems in which the off-grid system is connected to the electricity grid. Hybrid solar system is classified into three types such as All-in-one Hybrid Inverter (which contains a battery inverter/charger and solar inverter together with clever controls), All-in-one Inverter with no Back-up (works like a grid feed solar inverter which enables storage of solar energy in the battery system for the self-use), and All-in-one Inverter with Back-up (used as both an on-grid or off-grid inverter, which has a great backup capability).
Advantages of hybrid solar system:
• Allows consumers to store excess solar power or low cost (off-peak) electricity
• Allows using of solar energy during the evening times (known as self-use or load-shifting)
• Facilitates with backup power capability that helps to provide power during a blackout or grid outage like a UPS function
• Enables advanced management of electricity power and energy independence
• Reduces the power consumption from the grid
Solar Accessories
Solar accessories are important for all your small and large-scale power generation requirements. The main accessories used in solar power system installation are Batteries, Solar Charge Controllers, Off-Grid Solar Panels, and Solar Battery Enclosures.
Solar batteries: Solar batteries for home energy systems are made using lithium-ion batteries (lighter and more compact than lead-acid batteries) rather than lead-acid, and saltwater. Lead-acid batteries are used in off-grid energy systems that have a relatively short life, and lower DoD than other battery types. Saltwater batteries (newcomer in the home energy storage industry) don’t contain heavy metals as compared to other home energy storage options. Solar batteries are considered the best in terms of battery capacity & power ratings, depth of discharge (DoD), round-trip efficiency, warranty, and finest manufacturing facilities.
Solar charge controllers: Solar charge controllers are a voltage regulator to keep batteries from overcharging and also regulates the current coming from the solar panels going to the battery. A solar charge controller is categorized into two different technologies, PWM and MPPT. An MPPT charge controller is more expensive than a PWM charge controller but worth buying it even if expending more money.
Off-grid solar panels: This particular solar panel consists of a battery, charge controller, grid box, inverter, mounting structure, and balance of systems. Off-grid solar panels can store enough sunlight during the day, and use the excess power generated in the night.
Solar battery enclosures: Solar battery enclosures are used to keep your batteries safe from weather, and safe from theft. It is attributed with feature locking mechanisms that protect unauthorized people against possible electrical dangers if they happen to be tampering with your equipment. Battery enclosures for solar systems are pole-mounted or ground-mounted and suitable for indoor and outdoor applications.
What is solar panel and how it works?
Solar Panel is also known as Photovoltaic Solar Panel, made using smaller units of silicon. This is called a solar cell, which converts solar energy into electrical energy. Silicon is a semiconductor inserted between conductive layers in a solar cell.
How solar panels work? The process of solar paneling starts during the day time when proper sunlight is there. The sun rays fall on Solar PV Panels that are installed on your rooftop, and photovoltaic refers to the scientific process by which solar energy gets converted into electrical energy.
There are several silicon cells within each PV panel, and these cells react with photons (unit of light), which come from the sun to produce DC (Direct Current) or electricity. The direct current (DC) then travels into an inverter that converts it into AC (Alternating Current), which further used in your home, office, playgrounds and many other places. After this, AC current transfers to the distribution network in your home, which is capable of powering electrical appliances of your house. When Solar Panels produce more electricity than your home is using, the extra electricity gets shifted or stored in the grid. And, you can avail of the benefits for the extra electricity that your solar panels generate. Moreover, solar panels are available in different sizes and price ranges.

Working Principle of Solar Panels
Solar Panels work on the principle of the photovoltaic effect, which is a method of producing direct current electricity based on the principle of the photoelectric effect. Photovoltaic directly converts solar energy (sunlight) into electricity. When certain materials expose to sunlight they absorb photons and then release free electrons, and this phenomenon is called the photoelectric effect.
Solar cells or photovoltaic cells are used to convert sunlight into direct current (DC) electricity. Though a single photovoltaic cell does not produce enough amount of electricity, hence several photovoltaic cells are mounted on a supporting frame and electrically connected to form a photovoltaic module or solar panel. The current or electricity that solar panel system provide is dependent on the effectiveness of sun rays.
Types of Solar Panels
Solar Panels are classified into two types such as Monocrystalline Solar Panels and Polycrystalline Solar Panels.
Monocrystalline Solar Panels:
Monocrystalline Solar Panels are made using extremely pure mono (single) silicon crystal that helps in converting solar energy into electricity. Monocrystalline solar panels are suitable for easy installation in smaller areas, which requires a reasonable price. However, the monocrystalline solar panel installation is ideal for a larger area, but it makes it expensive. Users will be able to get the most electricity output according to the monocrystalline panels used.
Polycrystalline Solar Panels:
Polycrystalline solar panels are made using poly (multiple) silicon crystals and known as the most commonly used type due to price and efficiency. The cells used in Polycrystalline are a small amount of quantity that makes the Polycrystalline Solar Panels a bit less efficient. For this reason, users can install a large number of polycrystalline panels to generate electricity to meet their consumption needs. As compared to Monocrystalline Solar Panel, Polycrystalline Solar Panel is considered the commonly used type as they maintain a good balance between pricing and effectiveness.
Difference between Monocrystalline and Polycrystalline Solar Panel
The difference between Monocrystalline and Polycrystalline solar panels is the advanced technology that has made them practically interchangeable. Owing to the manufacturing process and robust technology, Monocrystalline Panels are quite expensive as compare to Polycrystalline Panels. The monocrystalline solar panel comes with black and dark blue color, whereas polycrystalline panel appears in the blue mottled.
Monocrystalline Solar Panels are more efficient than polycrystalline solar panels thus, you can use slightly more power in the same size and space of monocrystalline panels. But polycrystalline panels need more equipment to produce the same amount of electrical energy as monocrystalline. For this reason, the solar panel cost is less for polycrystalline. Interested buyers can purchase any solar panel through online and also by visiting stores.
When it comes to temperature, Monocrystalline panels handle the heat slightly better than polycrystalline solar panels. This temperature difference can be noticeable especially in extremely hot areas such as deserts, as compared to residential regions. Last but not least, monocrystalline can perform in a better way even on hazy skies than polycrystalline panels.
Solar Components are important for every home solar electric system to help in producing electricity and converting it into the alternating current; thereby using in home appliances, storing excess electricity, and maintain safety.
Solar components are classified into seven categories such as Solar Pumps, Solar Charge Controllers, Solar Combiners, Solar Mounting Structure, Solar Tools, Solar Cables, and Solar Surge Protection Devices. These all are functioned using solar energy (sunlight), which turns into electricity. The entire solar components are manufactured and stringently inspected as per International Quality and Safety Standard.
Solar Pump
The solar pump is a solar water pumping system operated using solar energy to pump clean water. The solar pump is ideal, especially for rural localities (beyond the reach of power lines), where people are unable to avail of electric consumption by using the local electricity grid.
Solar pump or solar-powered water pump is in demand due to its robust construction, easy installation, eco-friendliness, and minimum maintenance. Solar pumping is the best alternative for fuel-burning generators and windmills, in which the electricity is provided by one or several Photovoltaic (PV) panels to offer water even if using without electricity. The water supplied by the solar pump is used to irrigate crops, provide clean drinking water, and also offer water for livestock. Apart from these, some other application areas for which solar water pumping system is used including fountains, pools, ponds, and home pumps.
A solar water pumping system consists of a solar panel that provides power to an electric motor, which in turn is capable of powering a bore or surface pump. Hence, the water is pumped from the ground into a storage tank that provides a gravity feed, and for this reason, energy storage does not require for the solar pumping system. The life span of a solar pump or solar water pumping system is a maximum of 20 years, but a solar panel of the pumping system needs cleaning from time to time to run properly. People can purchase it as per their requirements because the solar pump price is varied from its manufacturing capacity, sizes, patterns, and different brands.
Benefits of using solar pump

Solar Charge Controller
The solar charge controller is a device, which maintains the proper charging voltage in batteries of any solar appliances. All solar electric systems with batteries should have solar charge controllers. The solar charge controller regulates the voltage, prevents overcharging and allows batteries to charge when required, because batteries can be overcharged if it feeds continuous voltage.
The main function of solar charge controller is to prevent overcharging of the batteries and regulates the amount of current the PV modules feed into a battery bank. However, charge controller can block battery bank current from leaking back into the photovoltaic array during night or cloudy times for saving to drain the battery bank.
Most home solar systems are built with a battery backup controlled using solar charge controller, which ensures that a consistent amount of electrical power is sent to the and the backup batteries of any solar system do not discharge during night or absence of sunlight. Solar charge controller price is very minimal so that anyone can buy it as per their necessities.
Solar charge controller or solar battery charger comes with two types of sizes and technologies such as MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) that are capable of functioning an off-grid power bank system properly. Charge controller is used within an off-grid or hybrid solar system with appropriate battery back-up.
Benefits of solar charge controller
• Works to control voltage and watts from Solar Panels
• Reduces the voltage of solar panels when a solar battery’s voltage is high
• Helps to maintain stable energy by preventing overcharging and protecting against overvoltage
• Stops reverse current during night or when sunlight is not available
Solar Combiner
The solar combiner or solar combiner box is a device operated using solar energy (sunlight) that combines the output of multiple strings of PV modules for connection to the inverter. Solar combiner is developed in such a way to bring the output of several solar strings together. Usually, each string conductor lands on a fuse terminal and the productivity of the fused inputs are then joined onto a single conductor that connects the combiner box to the inverter.
Solar combiner box also combines incoming power into one main feed, which distributes to a solar inverter that is capable of saving labor and material costs through wire reductions. Solar combiner is engineered even to provide overvoltage as well as overcurrent protection facilities to enhance inverter protection and reliability.
The solar combiner generally exist in between the solar modules and inverter, which is the correct position. Solar combiner can limit power loss when it is positioned in the solar system. Solar panel combiner box and solar string combiner box are two different types of solar combiner. Moreover, solar combiner is usually used in the larger commercial and utility scale PV power plants (greater than 500kW).
Benefits of using solar combiner
• Helps in improving safety of solar panels and the entire photovoltaic plant
