What is Solar Power System？
A solar power system is a system that converts sunlight into electricity. It consists of multiple components, including solar panels, a solar inverter, and sometimes a battery storage system and a solar charge controller. The system is designed to absorb sunlight and convert it into a form of energy that can be used for electricity.
Benefits of Solar Power System
Renewable energy source – Among the several benefits of solar panels, the most important thing is that solar energy is truly a renewable resource. It can be utilized in all areas of the world and is available every day. We can never run out of solar energy unlike some of the other sources that are being used excessively. Solar energy is readily accessible and available to us for as long as we have the sun which according to scientists is going to stay for at least next 5 billion years. The cost of solar panels has also fallen by 75% that should encourage everyone to go for solar.
Provides energy security – Another top benefit of installing solar panels is that no one can go and buy or turn sunlight into a monopoly. Combined with the ease of solar panels, this also provides a notable solar power advantage of energy security. This is why governments are investing huge amount of money into the development and installation of solar power systems.
Decrease the carbon footprint – Solar power decreases your carbon footprint as well. Carbon dioxide has been known to cause global warming that is causing havoc on our Earth further causing glaciers to melt, animals to be endangered and shorelines to erode. For example, solar power can help conserve more than 16000 gallons of water per year and also decrease dependence on non-renewable sources of energy. Reducing the mileage from 15,000 to 10,000 can save more than a ton of CO2 which is around 15% of the average person’s footprint.
Technology development – The technology in the solar power industry is continuously advancing and improvements are sure to intensify in the future. Innovations in nanotechnology and quantum physics can increase the effectiveness of solar panels or increase multi-folds the electrical output.
Low maintenance costs – Solar power systems don’t require a lot of maintenance. All you need to do is keep them relatively clean. The reliable solar power companies give 20-25 years of warranty. There is no wear and tear and the inverter is the only part that needs to be changed after 5-10 years. Basically, there is very little spending on maintenance and repair work.
Diverse uses – Solar energy can be used for diverse purposes such as to generate electricity or heat. It can also be used to produce electricity in areas without access to energy grid, to distill water in regions with limited water supplies, power satellites in space, in residential properties and recreational homes. These are some of the most popular diverse uses of solar power.
Reduce electricity bills and increase savings– As some of the energy needs will be met by the solar power system, the energy bills are sure to drop. It also depends on the size of the solar panel system and electricity usage. Not only you will save on the bill, but also generate more electricity than you can use, the surplus of which will be exported back to the grid provided it is connected.
Types of Solar Power System
On grid solar power system
These are the type of system which is having high usage in home, commercial and industrial purpose. Here the solar Power systems that only generate power when the utility power grid is available. They must connect to the network to function and can send excess of power generated back to the network when you are overproducing hence crediting for further usage.
Off-grid solar power system
An off-grid system does not connect to the electricity grid and hence requires battery storage. An off-grid solar system is a design which will generate enough power throughout the year and have enough battery capacity to meet the residential, industrial and commercial requirements, even in the depths of winter when there is dim sunlight.
Hybrid solar power system
Hybrid solar systems are known to generate power similarly as of the conventional grid-tie solar system, but it uses the unique hybrid inverters and batteries to store energy for the later usage. Their ability to saving energy has enabled it to act as a backup power supply similar to the UPS system. Hybrid systems combine solar power from a photovoltaic system with power generating energy source. Hybrid solar systems are the best way to use when the cost of electricity is high.
Application of Solar Power System
Residential and commercial utilization
Solar PV Modules find extensive applications in both residential and commercial settings, serving as power sources for homes, businesses, and industrial facilities. Their cost-effective nature makes them a viable solution for reducing energy expenses while promoting the adoption of clean energy.
Off-grid locations
Solar PV Modules prove advantageous in remote areas devoid of access to the electricity grid. They are well-suited for powering essential services such as communication systems, lighting, and other critical infrastructure in off-grid locations.
Agricultural implementations
Solar PV Modules play a significant role in agriculture by offering a clean and renewable energy source for various operations. These modules power irrigation systems, water pumping, and other essential farming activities
Power stations
Solar PV Modules are integral components of large-scale power stations, contributing to electricity generation for the grid. They play a crucial role in utility-scale solar power projects, delivering clean and renewable energy to communities at a larger scale.
Components of Solar Power System
Photovoltaic cells: They are able to capture direct sunlight as “photons”. They also comprise sandwiched layers of semi-conductor particles, like phosphorous and boron. When a sunlight particle hits such a photovoltaic cell through a photon, it automatically triggers the “electrons” contained within the semiconductor layers. This friction between the photons and electrons of a photovoltaic cell, produces electric energy, measured in “watts” of power. The higher is the energy produced by a solar power system, the wattage accordingly increases.
Solar panels: A cohesive cluster of photovoltaic cells form a solar panel. The size of the panel is determined by the number of photovoltaic cells in contains. This, in turn, determines the total power generated by the solar panel. A solar panel typically produces 250 to 400 watts of power.
Inverter: The electric energy produced by a solar power system is in the form of direct current (DC), more suitable to portable power banks and UPS. However, common electrical appliances like lighting and heating equipment, kitchen, and electronic equipment, etc. run on alternating current (AC). An inverter converts the DC produced by a solar power system into usable AC.
Battery: A solar power system can only generate solar energy with the availability of direct sunlight. This is great for powering appliances during the day. But what happens when you want to use solar energy at night, perhaps to power a light or a fan in your home? In fact, conventional electricity is more likely to be expensive during the night, as utility companies charge top dollar for these “peak” hours. This is where a battery comes in, to store the harnessed solar power for later use (typically during the night).
Racking and mounting systems for solar panels: When you see a solar panel—either installed on the roof of a building, or directly on the ground—you will notice it stays in place, despite the wind. This is due to racking and mounting systems that are used to “install” a solar panel on a property. There are also various types of racking and mounting systems to support different forms of solar panel installation (like roof versus ground, etc.).
Solar accessories: This can vary, depending on the type of the solar power system.
A: Solar charge controller: Once a solar battery is fully charged, based on the voltage it supports, there needs to be a mechanism that stops solar panels from sending more energy to the battery. This comes in the form of a solar charge controller, and is also responsible for protecting the battery from getting “drained” when it is not used. (This can happen in the absence of a solar charge controller, if the electric current reverses direction and flows back to the solar panel.)
B: Solar cables: As the name indicates, these are wires to interconnect the various components of a solar power system. They are designed to withstand the high temperatures that run through photovoltaic cells. They are also UV-resistant as they are mostly installed outside buildings (on the roof, or directly on the ground).
C: Solar meters: Elaborately designed solar meters are also available in order to measure, monitor, regulate and optimize the energy produced by a solar power system.
How to Maintain Solar Power System
Clean your panels
Hosing off your panels or washing them with a sponge will keep their efficiency up. Don’t use abrasive chemicals or materials that can lead to scratches–a soft cloth, hose, or simple dish soap is enough.
Look after the battery
We’re going to assume you’ve got lithium-ion batteries, because they’re simply the best option. One of the reasons why they’re the best is because they don’t really require maintenance, just a periodic cleaning: disconnect the terminals and wipe the battery down with a damp cloth before drying and reconnecting. If you go with something like a lead acid battery you’ve got to muck about with cleaning the terminals and checking fluid levels and such, and who wants to do that?
Just go with lithium-ion and make one less thing to worry about.
Charge controller
While you’re cleaning your batteries check the connections on the charge controller. Pretty much the only thing that might go wrong is if they somehow loosen and don’t connect properly.
Keep your inverter in good shape
Avoid placing heat-sensitive or flammable materials near your inverter. If the inverter has a cooling fan, ensure that it functions properly and the airflow is not obstructed.
You’ll need to clean it at least once a year to prevent dust and dirt buildup, which may affect the efficiency of the system. You can also avoid overloading the inverter with high electrical devices and appliances by using energy-saving electrical appliances. Using LED bulbs instead of ordinary bulbs and energy-efficient air conditioners or refrigerators can guarantee a long backup power time and prolong the service life of your inverter system.
Brief History of Solar Power Systems
The concept of utilizing the sun’s energy isn’t new – ancient civilizations used passive solar designs in their dwellings for heating. The modern era of solar power, however, began in 1839 when French physicist Alexandre Edmond Becquerel discovered the photovoltaic effect, which explains how electricity can be generated from sunlight. However, it wasn’t until 1954 that scientists at Bell Labs developed the first photovoltaic cell capable of converting enough sunlight into electricity to run everyday electrical equipment. Since then, solar power technology has evolved significantly, leading to more efficient and affordable solar power systems.
Polycrystalline Solar Panel Working Principle
These solar panels are made of multiple photovoltaic cells. Each cell contains silicon crystals which makes it function as a semiconductor device. When the photons from the sunlight fall on the PN junction (junction between N-type and P-type materials), it imparts energy to the electrons so that they can flow as electric current. Here, P-type materials are deficient in electrons while N-type materials have an abundance of electrons. Two electrodes are connected to the PV cells. The electrode that is on the top surface contains small wires while the electrode on the bottom is a foil-like conductor.
Solar Photovoltaic Systems: What's the Difference Between an Industrial and a Residential One?
Size: A residential panel is typically smaller, and will generate less power because it serves fewer people. An average panel for the home will have 72 cells. while a commercial panel will be wider, and have 96 cells. The price of a panel is calculated by the amount of power it produces, and not its size. So a 10 kWH system for a home will cost the same as one of the same power for a business.
Efficiency: Since industrial panels are larger than their residential counterparts, they are more efficient at producing energy. Industrial solar panels have an efficiency of 20%, making them about 2% more efficient than residential panels.
Installation: Industrial solar panels usually take longer to install because of their greater complexity – from a week until up to a month. Installation of residential solar panels generally takes one or two days.
Color: Solar panels now come in many colors, but they are less efficient than the standard blue and black colors. In general, industria lsolar panel systems are black with a white backing, and residential customers chose black panels on a black backing.
