What does a Solar Panel Inverter do?
Solar panel inverters function as micro-power stations, absorbing the solar energy and brewing it into electricity, DC, the produced source, will be an outcome. Like the old-fashioned homes, the modern ones. However, have started using Alternating current (AC) to power devices, lights, and electronics. It is when the solar inverter becomes the mediator, performing his/her most important role in this shift.
In general, the function of the solar panel inverter for home is similar to the ordinary one in the sense that it transforms DC power into usable AC power for your home. The conversion procedure of the inverter is done using a modulated rectifier to convert AC to DC. One of the key roles of an inverter is voltage regulation, the system acts as the pressure regulator for electricity. The voltage level to be provided by power lines must remain constant and safe. In order to make the proper work of your appliances possible.
Fundamentally, the role of the solar panel inverter for home is to smooth and convert the DC electricity generated from the solar panels into AC power which is then used to power your house. This makes it possible for you to use the clean electricity that is being generated from the sun directly.
What are the types of solar Panel Inverters?
There are three main types of solar panel inverters:
- On-Grid Inverters: Currently at this point, the most popular one is a grid-tied inverter that converts DC electricity into AC and synchronizes it to the grid. If there is any surplus solar electricity being fed onto the grid. It may result in receiving credits (i.e. money back) from your electricity company.
- Off-Grid Inverters: An off-grid device will be suitable for places without access to a power grid. The solar panel inverter of this off-grid inverter device will convert the power in the form of DC to AC. And then store the remaining power during daytime in a solar inverter with battery for home for its use at night.
- Hybrid Inverters: These hybrid inverters which possess the advantages of both grid-tied and off-grid inverter at the same time. They let you consume power from the grid apart from the batteries that serve as a mean for storing solar energy generated during grid failures.
The following table compares the three types of solar inverters:
| Characteristics | On-Grid | Off-Grid | Hybrid |
| Compatible with | On-Grid Solar Power Systems | Off-Grid Solar power Systems | Both On-Grid & Off-Grid Solar Power Systems |
| Energy Storage | No solar energy is stored. | Solar energy is stored in batteries. | Solar energy can be stored in batteries. |
| Power Transfer to Grid | Excess power gets transferred to the utility grid. | Power is not transferred because it is not connected to a grid. | Excess power gets transferred to the utility grid. |
| Anti Islanding Feature | Present | Absent | Present |
| Price Range | A 3kW On-Grid Inverter costs about Rs. 30,000- Rs.40,000. | A 3kW Off-Grid Inverter costs about Rs. 30,000- Rs.40,000. | A 3kW Hybrid Grid Inverter costs about Rs. 70,000- Rs.80,000. |
What to look for when buying a solar inverter?
Selecting the appropriate solar panel inverter seems from a thorough examination of numerous variables. That will help your system to operate effectively and render a significant return on your investment within the system’s lifetime. Here’s a concise breakdown:
- Warranty: A longer warranty duration (preferably 10+ years) should be offered to assure customers. That they will not be encumbered by unnecessary financial responsibilities when repairing or replacing the product in the future. Try to search for guarantees for both materials and workmanship errors.
- Operating Temperatures: To choose the solar panel inverter that can stand the range of temperatures in your locality without compromising on the efficiency. The temperature derating of the inverter sometimes implies a loss of the output power as the temperature is increased. Picking a solar panel inverter with a greater operating temperature range or one manufactured for your region assures the solar inverter duly operates throughout the season.
- Efficiency: Ensure that the solar panel inverter that will reverse the current, from the direct current (DC) generated by your rooftop solar panels to alternating current (AC). Which feeds most devices, has a high efficiency of 95%+ or higher, to reduce losses during the conversion process. A higher efficiency level represents the amount of power output you can get from your solar system.
- Power Rating: The capacity of the solar panel inverter could be expressed as P-max and it should be correlated with the total wattage of your solar panels. Meanwhile, the solar inverter must be chosen with a P-max exceeding the panel’s unite power. So it can hold future system expansion or individual panel’s characteristic variations under the real-world conditions.
- Safety: Confirm the conformity with the acceptable safety certifications that are offered by Underwriters Laboratories or International Electrotechnical Commission for example. Such certifications serve as evidence that the solar panel inverter is safe as set out in strict regulatory standards, thus reducing the risk of electrical hazards.
What type of Solar inverter is most efficient?
One of the most crucial points in getting a high yield from your solar panel system is the power of solar inverter essentiality. Solar panel inverter for home perform the critical role of transforming the direct current (DC). Generated by the solar panels of your house into usable alternating current power (AC) for your home. Nevertheless, the presence of this lack of perfection cannot be taken lightly even though the solar inverter determines the amount of usable AC power which is finally set up. The grid-tie inverter, which is most commonly used for grid-attached solar systems in residential areas. As well as being one of the most significant aspect of such systems, must be given special attention.
Impact of Inverter Efficiency:
Power loss from the conventional inverter is nearly 1% meaning 99% of energy input is converted into 4,950 watts of AC power irrespective of the source. Next is a high-efficiency converter that operates at 97% implicating that only 3% of power is lost. However, a lower efficiency solar panel inverter runs at 90% will only deliver 4,500 watts of AC power. Meaning a big waste of energy for the grid.
Which inverter is best for solar rooftop panels?
Each kind of solar panel inverter has benefits and weaknesses. And the chosen one depends on the particular solar project. The solar installers‘ area of expertise/strength is to have knowledge of all the solar inverter types. And to help you select the best suit solar panel inverter for your home.
For example:
The main benefit of Microinverters and Power optimizers is that you can either have a complex roof with solar panels facing in different directions (or mixed in the shade). Or use a simple roof where no shading is possible. A string inverter is a solar panel inverter for homes with flat roofs whose solar cells are in order due to shade-free and same direction. The low increase in output in this case is because, with microinverters and power optimizers. Module-level enhancements do not exceed 5 to 10 percent.
Considering that the hybrid string inverters are a good fit. If you plan on incorporating a system that runs a solar inverter with battery for home in addition to your solar panels. You should definitely factor the hybrid string inverters in your list. The best solar panel inverter for homes as well can go for more than $10,000 for a single installation.
What is the cost of a solar panel inverter?
An electrical converter known as a solar inverter is used to convert direct current (DC) into alternating current (AC) at a utility frequency. Which can then be supplied into the main grid in an off-grid solar system. In off-grid and hybrid solar systems, the opposite is also true. It is a crucial component of the solar system. Special features of solar panel inverter for homes include maximum power point tracking, frequency, voltage, power factor, and anti-islanding prevention.
