With the increasing scarcity of non-renewable energy resources on earth, the development and utilization of renewable energy has attracted more and more attention. For example, solar energy resources are inexhaustible green and environmental protection new energy products. The state has also issued relevant policies to encourage and support the development and utilization of solar energy.In the lighting industry, solar street lamps are one of the hottest products at present. They are indeed much more expensive than ordinary circuit lamps in terms of price. However, considering long-term energy conservation, environmental protection, and later maintenance, the comprehensive price of solar street lamps is much cheaper than traditional street lamps.Today we want to explain to you how to calculate the configuration of lithium battery solar street lamps?We take a 40w led light source as an example: the customer requires 8 hours of lighting every day, taking the sunshine peak value of 3.9 as the reference, and the cloudy and rainy days are calculated as 3 days.How to calculate the capacity of lithium battery?Let’s take 18650 ternary lithium battery as an example:Known conditions: the nominal voltage of a lithium-ion secondary battery is 3.7V; The system voltage of a 40 wled lamp light source is 12V; The platform voltage composed of three lithium batteries in series is 11.1v, and the standard charging voltage of the battery board is 17.5V.First, let’s popularize the conversion of ah (ampere-hour) and wh (watt-hour) unitsWh (watt-hour) and ah (ampere-hour) are both ways to measure battery capacityAh is a unit to measure the capacity of power storage equipment. It means that it conforms to the discharge curve (a curve similar to inverse proportion). At this time, it can meet the result that the product between current (ampere) and discharge time (hour) is the capacity unit [ah].We often see a number in wh next to MAH.Work done by the battery W = UIT = voltage (V) * current (a) * time (H),The voltage U * current I = power P (watts, English letter “W”)Therefore, the work done by the battery W = P * t, the unit is whAh = work (W) / voltage (U)Back to the point,Daily power consumption of 40 wled light source = 40W * 8h = 320whThe design of solar street lamp shall consider the cloudy and rainy days of the day, taking 3 days as an example,Then the total power required by 40wled light source in 3 days = 320wh * (3 + 1) days = 1280whThen the capacity of lithium battery = work (W) / voltage (U) = 1280wh / 11.1v = 115ahHow to calculate the power of solar panels?Daily capacity of lithium battery = 115ah / (3 + 1) days = 28.75ahSolar panels receive sunlight during the day, and the power used to charge lithium batteries is 20-30% higher than that used by light sources every nightThen the daily charging capacity is 28.75ah * 1.3 = 37.375ahAccording to the effective sunshine duration per day, it is calculated as 3.9 hoursThen the daytime charging current = 37.375ah / 3.9 = 9.58aThen the power of solar panel P = u * I = 17.5V * 9.58a = 167.65wBased on the charging efficiency of the mono solar panel is 80%,Then the actual required solar panel power = 167.65w / 0.8 = 209.5625wIf it is an 18650 lithium iron phosphate battery, the nominal voltage of a lithium-ion secondary battery is 3.2V; The platform voltage composed of four lithium batteries in series is 12.8v.If the system voltage is 24V, the standard charging voltage of the solar panel is 35V, the platform voltage of the ternary lithium battery is 22.2v, and the platform voltage of the lithium iron phosphate battery is 25.6v.The charging efficiency of poly solar panels is 75%.When calculating the configuration of lithium battery solar street lamps, we must comprehensively consider the power demand of customers, such as daily lighting time, sunshine peak value, and rainy days in each city.Otherwise, the unreasonable configuration of solar panels and lithium batteries will have a great impact on the normal operation of the system, which will not only affect the service life but also increase the after-sales maintenance cost. If the configuration is small, Insufficient power generation will cause irreversible use consequences.

The demand for stable and uninterrupted electricity is soaring to new heights. No matter the need, it’s an integral part of our daily lives- be it for charging mobile devices, running personal computers and home appliances, lighting fixtures, etc.Nearly everything we use daily needs electricity to run. Naturally, this translates into the need for readily available power any time of the day. As such, the cost of electricity is growing too. This raised the demand for clean, alternative sources of electricity. And what could be better if you don’t need to pay for using the energy because it’s available in nature in abundance?Welcome to solar power – one of the most popular forms of renewable energy. The radiant light and heat from the mighty sun can accommodate the growing energy demands of consumers and businesses across the globe.The clean energy source is seeing wide-ranging adoptions, and thankfully, it paves the way for a green world and a future liveable for future generations. This article will cover some crucial points related to solar energy, with most of the focus drawn towards solar rooftops and how they can be beneficial for an average homeowner.Content of the article –What is a solar rooftopHow solar rooftop worksWhy go for solar rooftopsPayback period of solar rooftopsSolar energy is a powerful source of unlimited renewable energy. Most importantly, it does not produce CO2 emissions and gases harmful to the environment. Also, it does not need resources such as water and wind. Thankfully, India receives a lot of sunlight annually, which makes harnessing solar energy feasible and practically beneficial. But to leverage on the power of the sun, and convert it into usable electricity, it needs to be supported by a system. One way to use solar energy is to install solar rooftops.What are solar rooftops?As the name suggests, solar rooftops are solar panels mounted on the top of buildings – be it commercial, residential, or institutional. A solar panel is an assembly of PV (photo-voltaic) cells that are mounted in a frame. How does a solar rooftop work?The working of solar panels is interesting. First of all, the sunlight hits the panels on a rooftop. It then converts particles of sunlight into DC electricity. A solar inverter now changes the DC electricity into AC. The generated electricity is then sent through the wires into homes which power appliances.Why go for solar rooftops?Job creationThe production of solar panels needs moderately skilled labour. Even setting up the solar panels on a rooftop and post-installation maintenance requires human resources. On a broader scale, planning, designing, manufacturing, administration, management and maintenance etc., continue to provide employment opportunities. In the future as demands for renewable energy sources increase, new job opportunities in this space are expected to grow.Low environmental impactTraditional energy sources create air and water pollution and are hazardous to the environment since they produce greenhouse gases. Pollution alone kills so many people in the world globally. Although some man-made environmental disasters are irreversible, it’s time to think about a clean and green future to control the impact of pollution and make the planet livable for us and future generations. Solar energy is clean and is pollution-less and thus stands as a highly relevant energy source for the modern world.The non-perishable nature of renewable energyTraditional power sources are non-renewable, which means they can become short in supply and at one point, they will cease to exist. On the other hand, the sun is a renewable resource, meaning it will never go short in supply. So, harnessing solar power for a predictable and confident future is the need of time. Save on utility bills and stay unaffected by their rising price.One of the most powerful reasons people are readily opting for solar energy is that it can bring considerable savings on monthly electricity bills. Just install the solar panels and at a place on the roof that receives enough sunlight. Slowly you will start to see huge savings over time. Also, since energy bills could rise, setting up rooftop solar panels allows one to continue generating free electricity without being dependent on external sources.Reliable power sourceSolar energy can be stored so that you can use the stored electricity to address the energy demands during the night or when the sun is not shining brightly.Low maintenance costSolar rooftop panels require low maintenance, or they could run for years without noticeable maintenance. All you need to do is wash off the dust and dirt only a few times a year. And for that, you may need professional help.Increase the value of propertyAs people are growing aware of the value of solar energy, its demand is constantly rising. For this reason, homes that are equipped with solar rooftop panels fetch the better market value.Avail the incentivesBased on where you live, the cost of installation of a solar system can go down significantly through incentives and rebates. Before installing a solar rooftop panel, do your research and consider consulting with an expert to understand whether you qualify for incentives and if so, what are the steps to avail them.Payback period of solar rooftopsThe payback period of a solar system could be 7 to 10 years. Which means, after that period, all you get is free electricity for the life of the installed panels, which could be as much as 25 years or more.Given all the reasons, it makes sense to choose solar panels for home. While choosing to buy solar panels for a house, always consider products from a reputed brand.

The complete household comes to a standstill without electricity, and thus, various ways are induced to maintain its continuous flow.The power of the sun, if channelized well, can be used to power up TVs, ACs, heaters, computers, microwave oven, and various other devices without interruptions and, at the same time, provide you with a great opportunity to save the monthly electricity cost. Making an intelligent and diligent investment in utilizing solar energy is the future. It also helps in reducing the carbon footprint, the dependency on centralized power supply, and much more.Solar power is one of the popular types of alternate electricity source to be installed at homes. It is a highly reliable and sustainable power resource that can effectively run any and every device in your home. The various components of the solar power system include:Solar Photovoltaic Panels: These are the essential parts of a solar power system that helps commercial and residential spaces to utilise natural sunlight as a useful resource. They are the most visible element of your system and, thus, the most familiar one. Solar panels generate DV electricity as the sunlight stimulates electrons to move through solar cells that are in-built into the solar panels.Inverters: Solar Inverters are a crucial part of solar technology. It converts the DC energy generated by the solar panels into AC current, which can then be used by all of the household appliances. These inverters transform the energy output from solar panels into consumable electricity form used in residential or commercial properties. The inverter is an essential piece of equipment that works constantly throughout the lifetime of the solar system, so it tends to be the piece most likely to have faults. The various types of solar inverters include:Off-Grid Inverters: These inverters are taken use in remote systems where the solar inverter is fed DC power from a battery panel. The said battery panel is charged by solar panels.Grid-Tie Inverters: These inverters got their name from the fact that they are associated with the grid. They feed power in the electricity grid by corresponding phase and frequency.Battery Backup Inverters: These are special types of inverters that are particularly designed to draw energy from a battery. The charge of the battery is preserved by using an onboard charger, and additional energy is transferred to the grid.Micro-Inverters: These are modern inverters in the solar industry. They are small, compact size and portable with a lot of performance. They are well-equipped with all the features of any central inverters.Racking: Mounting or racking is the third most important component of the solar system. This is the thing that attaches your panels to your roof. Racking needs to be well thought of and of quality equipment from trusted brands. It should be ensured that correct procedures are followed, and the performance and safety of the solar energy system and family are guaranteed.Batteries: Batteries are equipment that is used to store energy generated during the day to be used throughout the night. Battery technology is fastly developing into a more feasible option for those who primarily use their energy in the evenings. The value of installing batteries in the solar system depends on a range of factors like power requirement, usage, etc.   Factors To Look Before Installing Solar Power SystemBefore installing the solar system in your home, one should be aware of various factors and considerations of their household. These factors help in making the right choice for your house. These factors are:Basic Considerations:Calculate the approximate energy requirements and how much you are expecting to cover with a solar array.The monthly and annual energy consumption.How to optimise the electrical wiring of the house?How much peak sunlight you can expect for the region?Roof directionMinimal shadingHow much will solar panels are required: It’s important to see how much solar panel coverage will you need to almost completely meet the needs of your power consumption.

What’s The Difference Between A P.W.M. Controller And An M.P.P.T. Controller?Without going too much into detail, these are the basic fundamentals for each of the controllers:Pulse Width Modulation (P.W.M.) Charge ControllerA P.W.M. controller is the more basic of the two controllers. They match the solar array voltage to the voltage required to charge the batteries.The way a P.W.M. controller works is by simply turning on and off (hence called pulse rate modulation).When the P.W.M. controller is on, it will send power to the batteries.When the P.W.M. controller is off, it will monitor the capacity of the batteries making sure to properly charge the batteries throughout the full state of charge.A P.W.M. controller is around 10% – 40% less efficient when compared to an M.P.P.T. controller.A PVM controller can cause interference to the on-board radio equipment. This is due to the sharp pulses generated for the battery bank charging.A P.W.M. controller generally tends to be around half price or less.Maximum Power Point Tracking (M.P.P.T.) Charge ControllerThe added functionality of an M.P.P.T. charge controller is that it can electronically track and deliver the most optimal amount of power coming from the solar array to the battery bank.If the output voltage of the solar array (24V, 48V or more) is higher than the battery bank voltage (which is usually 12v), the controller will intelligently bring the power down to the optimal charge voltage. This is generally between 13.8v to 15v. The controller will also compensate for the ‘drop’ by increasing the current.As with the P.W.M. controller, the M.P.P.T. charge controller can monitor the capacity of the batteries, and then match the necessary voltage required to charge those batteries.Another benefit of an M.P.P.T. controller is a reduction of the wire size (gauge) needed when connecting a solar array that is connected in series. This is due to the higher voltage/lower current coming from the solar array.An M.P.P.T. controller is around 10% – 40% more efficient when compared to a P.W.M. controller.An M.P.P.T. controller generally tends to be around twice the price or more (depending on technology/make).
