Solar energy has made great progress in the past decade. With the decline of technology price, the demand for solar PV is also increasing. There are many reasons why people install solar PV, but most people see it as a way to help reduce electricity bills and carbon footprints. Once you have installed solar panels, it is important to understand how to make the most of them.
Against the backdrop of today's global energy transition, grid-connected photovoltaic (PV) systems, as an important component of renewable energy, are gradually penetrating various fields such as homes, warehouses, and commercial buildings, aiming to reduce dependence on fossil fuels and promote the greening of the energy mix. Hybrid solar inverters, as a key component in this system, provide strong support for maximizing the use of PV power with their efficient and intelligent energy management features.
In normal operation and in general, the solar panels do not generate noise, as they are manufactured and designed to be noise free equipment, especially in night time, but even at day time where the sun hits the solar panel and it works to generate electricity, there will not be a noise.
Net Metering is one of the dominant arrangements the electricity company dealing us in billing when we install our new solar photovoltaic system. Under this arrangement, the electricity generated from the solar inverters and the solar photovoltaic system will go to feed our home (electrical loads) at first, and then the additional excess generated electricity which is not required by our home electrical appliances/loads will be exported to the power grid.
In some kind of solar photo voltaic system called Off Grid system, your solar system will incorporate batteries that can feed your loads with electricity in case of low sun radiation and night time. But such batteries add a significant cost to your solar system, so it is usually recommended to be used in remote areas in where there is No regular electricity supply exists.
The energy metering system is an important component in our solar system, because it tells us how much electricity our solar system generates, how much electricity our electrical appliances and equipment are using and the amount of electricity we are still buying for the power utility or export to the power utility after connecting our solar system to the power grid.
When Solar System company/installer design our solar photo-voltaic array, they specify two standard slopes: The first is the orientation which means the solar panels face direction, whether it will be to North, South, East or West, and the second is tilt angle which means the solar panel angel with horizontal surface "roof angle". Ideally, solar panels should face the south, and the tilt angle should equal to the solar system location latitude, so we can get maximum electricity production from our solar phot-voltaic system.
As the global demand for renewable energy continues to rise, more households are opting for solar photovoltaic (PV) systems to reduce electricity bills and minimize their carbon footprint. Specific metering methods are used to track interactions between solar energy generation and grid electricity when connecting a solar PV system to the power grid. The two primary methods are Net Metering and Gross Metering. In this article, Home Power Inverter will explore how these two metering systems work, their advantages and disadvantages, and how to choose the best option for your needs.
The photovoltaic off-grid power generation system is mainly used to solve the basic electricity consumption problem for residents in areas without electricity or insufficient electricity. The photovoltaic off-grid power generation system is mainly constituted of the photovoltaic component, bracket, controller, power inverter, storage battery and power distribution system. Compared with the photovoltaic grid-connected system, the off-grid system has an additional controller and storage battery. In addition, the inverter directly drives the load, so the electrical system is more complicated. Since the off-grid system may be the only power source of the user and the user relies more on the system, the off-grid solar system design and operation must be more reliable.
The solar energy charge controller is an automatic control device controlling the solar battery array to charge the battery and the battery supplies power to the solar inverter load in the photovoltaic power generation system. It can set the control conditions according to the charging and discharging characteristics of the battery, so as to control the power output of the solar energy battery component and battery to the load. Its main function is to protect the battery and stabilize the working state of the power station. The photovoltaic solar controller can be divided into a switch type controller, a pulse width modulation (PWM) type charge controller, a maximum power point tracing (MPPT) charge controller, and an intelligent controller according to functions and circuit structures.
