    0kw grid tied solar system work in Philippines

    Grid tied solar system is a very good system for people have stable grid grid-tied solar systems power, and want to reduce the electric bill in daytime.

    If you place not allow sell solar power to local power company, you can still use the grid tied solar system to help you reduce the electric bill which use most in daytime.

    Gird tied solar system is very useful for

    Check here for more detail for the 200kw solar system. Both on-Grid and off-grid for your different need.

    How the grid tied solar system work?

    The grid tied solar system working mode:First use the solar power first, and there would be 2 condition:

    The 0 export will stop the exceed power send to the grid, in this time, the electricity bill is 0, solar help you paid the bill.

    For example, your energy need is 5kw, and solar supply 3kw, the rest 2kw will get from the grid. In this time, solar can still help you save bills.But when the grid is down, the grid tie solar system will not working.This is to protect the people who is repairing the grid.

    Although there are a double way meter in this photo, if your place not support sell solar power to the local power company, you can put a 0 export to stop the exceed power send to the grid.

    How is a 0 export work in a grid tied solar system?

    The inverter has external zero export function. This function is optional. It can collect countercurrent power to control the output power of the inverter, so that the power of inverter and load can be offset, and the excess power will not be fed back to the grid.

    This is a connection diagram of a sensor clamp, which will stop the exceed solar power send to the grid.

    If you don’t have the 0 export, and your local power company not support sell solar power, and your solar is more than energy need, the exceed power to feed to the grid.

    That means you will have to paid the exceed solar power. That’s not help you save the bill but to heavy your bills.

    Why the owner uses the grid tied solar system?

    The city grid in his place is very stable

    The city grid power is stable in his place, but expensive. Before he choose to use the solar system, his bill is around 15,840 for one month around 72000kwh.

    This is a food factory with Color steel sheet, 48m x 40m.

    After we assessing the site’s electricity demands it was established that a 200kW solar array was the best fit. Firstly, when sizing a solar array we look to understand the client’s goals. In this instance, it was to max returns so we designed a solar system as large as possible whilst keeping export to a bare minimum. As a result, this system comprises 6pcs 33kw inverter and 200kw panels across the shop roof and canopy; max the total roof space.

    And the solar panel power is 200kw, in our plan, the system will help him reduce 30000kwh each month. Because in Philippines, the sun conditioner is really good, the factor can be 0.85 most in our plan.

    With the help of solar panel, the electricity reduce half compared to before.

    And the system cost is return in the third year, and enjoy free solar power at the 4th year.

    Construction Drawings (Electrical) for the grid tie solar system

    In the food factory grid tied solar system, there are 6pcs 33kw inverter. And each inverter with 33kw solar panel.

    What happen if the grid stop?

    When the grid stop, the inverter will stop, won’t send any power to the grid. Because when the grid stop, the people may work in the utility power line for repair. The stop power will hurt the worker. So every grid time solar inverter is design when the grid stop, it stop.

    How Many Solar Panels Do I Need

    Installing a solar panel is a great way to minimize your energy bills and utilize the sun’s energy. It does not only have low maintenance costs but is also safer for the environment.

    So if you want to install a solar panel on your property, then you must determine how many solar panels would be sufficient for your needs. This will make the installation process seamless and help you save money. In this article, you will learn to calculate how many panels you need along with other fundamental information. So if this sounds compelling, read along.

    How to Determine How Many Solar Panels You Will Need

    There are several factors that can affect the number of solar panels you will need. We’ll talk about them in a few minutes but first, let’s talk about the mathematical formula that you must know to determine the system size that you need. You simply have to divide your kWh per year by average sunlight 30. After determining the KW that you need, you can take the space in your roof into consideration to get the ideal number of panels.

    If your roof has enough space, then you could use cheaper panels and spread it across the area. For people who have a small roof, power panels would be suitable as they would provide good power without needing extra space. Here is a chart for your reference:

    Average Energy Bill/month Size Of Solar System Number Of Panels (330W) Estimated Space Required
    120 10kW 32 Panels 624 sq.ft
    600 50kw 157 Panels 3,061 sq.ft
    1200 100kW 438 Panels 8,541 sq.ft
    2400 200kW 556 Panels 10,842 sq.ft

    Figuring out how many panels you need

    If you are still confused about how many panels you need, then here we have given two examples. So first, let’s assume you are a business owner who needs solar panels for his business property.

    The majority of small and mid-sized business institutions require a 50kW to a 200kW. This is a general range, so you must assess your needs first, then make a decision. For example- if your monthly electricity bill is around 1500 to 3000, then a 200kW solar system would be ideal to satisfy your needs. This type of system will need around 3000 sq. ft of space as well as 150 330 W solar panels.

    On the other hand, a 5kW to 20kW solar system is perfect for most homeowners. Though if you have extra appliances and amenities like a heated pool, then it might vary. For example- if you are a regular user with approx a 120 electricity bill each month, then you will have to install a 10kW solar system. This system will require 624 sq. ft and utilize 32 330 W solar panels.

    Things that Influence How Many Panels you’ll Need

    As mentioned above, it’s time to talk about the factors that affect the number of solar panels you will need.

    Your Monthly Or Yearly Electricity Cost Usage

    The amount of electricity you use can greatly affect the number of panels you will need. That’s why it’s best to look at your previous electricity records (6 to 12 months). This will help you figure out your electricity needs and you will be able to make a good decision. You should check the appliances in your home and consider future electrical upgraded too. For example- if you will be buying a new fridge or invest in an HVAC system soon, then your electricity needs will also rise. So keep these factors in mind before installing a solar system.

    charter, hall, 200kw, solar, system

    Average Daily Sunlight

    Solar systems require solar energy, so you must know the average sunlight that you get in a day. It’s important because two same-sized solar systems will provide different results if they are receiving different amounts of sunlight. Once you know about the average daily sunlight that you get, you can use the equation to decide how many panels you will need.

    Type of Solar Panel

    You should know that not all solar panels are not created equal, and their efficiency varies from one model to another. For example- some solar systems have an efficiency of 21%, while some can be slightly weaker with 15% efficiency. That’s why you should work with a reliable solar power installation company to get the best service and results.

    How to calculate the number of solar panels you need

    To calculate the number of your required solar panels, first, you need to figure out your annual electricity consumption, panel wattage, production ratios. Determining yearly electricity usage is not that difficult. You could have a look at your energy bills, and you will get the number (kWH). According to EIA, an average American utilizes around 10,649 kWh of electricity/year.

    Solar panels come in a broad range of power, generally from 250 to 100W. So you can decide the Wattage as per your needs, here we are taking the average, which is 320W. Production ratios are also easy to determine as it’s just the ratio of the energy that the system generates to the size of the system. Let’s say your system is 10kW, and it generates 16kWh of energy, so the production ratio will be 1.6 (16/10).

    Once you have all the factors, you only need to use the equation, which is system size/panel wattage/production ratio = No of panels. So if we put the numbers here (10.649kW/320W/1.6), then we will get our answer, which is 25 panels.

    How much roof space will you need?

    The roof space that you will need depends on the number of solar panels you want to install. For example- you will need 360 to 600 sq. ft of roof space to install 20 to 35 solar panels. Nowadays, the majority of residential solar panels have an area of 17.55 sq. ft. So multiple this number with the number of solar panels you want to install, and you will know how much roof space you will need.

    Solar panels have gained great popularity in recent years, all credit goes to their long-term benefits. It helps you reduce your energy bills without harming nature. The best way to figure out how many solar panels you will need is by determining your energy needs. The number of appliances you use also plays a major role, that’s why it’s essential to calculate everything properly. If you are unsure what to do, then taking the help of professionals is also a good idea as it will reduce the chances of any errors.

    Kilowatts (kW) to Amps Conversion Calculator

    Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications.

    Kevin Weekly holds a PhD in Electrical Engineering and Computer Science (EECS) from the University of California Berkeley and Bachelor’s degrees in electrical engineering and computer science from the University of Texas.

    How to Convert Kilowatts to Amps

    It is possible to convert kilowatts (kW) to amps using the Watt’s Law power formula. The power formula states that current = power ÷ voltage.

    To adapt the power formula to using kilowatts, first start by converting kilowatts to watts, which can be done by multiplying the power in kilowatts by 1,000 to get the number of watts.

    Then, apply the power formula by dividing the power (in watts) by the voltage (in volts) to find the current (in amps).

    kW to Amps Formula

    Thus, for DC and single-phase AC circuits, the formula to convert kilowatts to amps is: [1]

    The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts.

    For example, find the current of a circuit with 1 kW of power at 120 volts.

    So, generating 1 kW of power at 120 volts will draw 8.33 amps of current.

    How to Account for Motor Efficiency and Power Factor

    Equipment is often not 100% efficient with power usage, and this must be factored in to find the number of amps consumed for a given output power. Efficiency of the motor η, is defined as the ratio of power output to power input.

    To find the input current required to achieve a certain motor output power, use the following equation.

    Thus, the current I in amps is equal to the power P in kilowatts divided by the voltage V in volts times the efficiency η.

    The magnitude of real and reactive together in alternating current power is called the apparent power, and the power factor is the ratio of real power to apparent power. [2]

    To find the input current required to achieve a certain motor output power accounting for power factor and efficiency, use the following equation. [1]

    The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts times the efficiency η times the power factor PF. Try our power factor calculator to get the power factor if needed.

    For example, let’s find the current of a 5 kW motor with an efficiency of 75% and power factor of 0.8 at 240 volts.

    I(A) = 5 kW × 1,000 / 240 V × 0.75 × 0.8 I(A) = 5,000 W / 144 V I(A) = 34.72 A

    In this example, the 5 kW motor will draw 34.72 amps of current.

    How to Find the Current of a Three-Phase AC Circuit

    The formulas to convert kilowatts to amps for a three-phase AC circuit are a little different from the formula for a single-phase circuit. Use one of the formulas below for line to line or line to neutral RMS voltages. [1] [3]

    Using Line to Line Voltage

    This formula measures the current draw for one pair of wires in the three-phase system; to calculate the current for all three pairs of wires, you need to multiply the result by three.

    Using Line to Neutral Voltage

    This formula measures the current draw for all three wires in the three-phase system; to calculate the current for a single wire, you need to divide the result by three.

    For example, find the current usage of a 25 kW three-phase motor with an efficiency of 80% and a power factor of 1 at 240 volts (line to line).

    I(A) = 25 kW × 1,000 / 240 V × 0.8 × 1 × √3 I(A) = 25,000 W / 332.55 V I(A) = 75.18 A

    Motor Current Ratings (Three-Phase AC)
