PV Meter

Wholesale PV Meter

A PV meter, also known as a solar meter, is a device that is used to measure the kWh production from a PV system. To be more specific, solar meters collect the PV yield production and local energy consumption to monitor and analyze PV plant performance. Solar meters usually come with a monitoring function to alert the owners of the PV system of issues with the PV system performance, letting them quickly resolve issues and maximize the return of investment. PV system data is transferred to a monitoring platform that provides a concise presentation of PV yields, monetary savings, and system performance. 

Solar meters, which do the measuring, can be internal or external to the inverter. All inverters include an internal meter, but oftentimes, these meters are not revenue grade. External meters can be installed along the AC line between the inverter and the main distribution panel. This allows one meter to measure the output from multiple inverters, which can create significant cost savings as well as a collection of more precise PV yield data if the meter is revenue grade. Moreover, a few solar meters can connect directly to the inverter through an RS485 or Ethernet cable, providing additional data for system monitoring and diagnostics.

How Does a Meter for Solar Work?

In order to measure electrical power (kW) — the rate of production — two aspects must be measure: current and voltage. The current represents the amount of electricity (electrons) flowing through a conductor. Meanwhile, the voltage represents the pressure pushing the electricity through the conductor. 

The current is usually measured by sensing the strength of the magnetic field produced when electricity flows through a conductor. A current sensor installed around a conductor is the current transformer (CT). The voltage is measured directly by the meter via two or more connections to the electrical service. The meter multiplies the current by the voltage to calculate apparent power (VA) and compares the current and voltage signals to calculate the power factor (Pf). The apparent power is multiplied by the power factor to calculate real power (P). Real power is then integrated over time to calculate real energy (kWh). 

What Are the Different Types of PV Meters?

Net Meters

Net meters show the net consumption of power in the household. A net meter does not show how much solar electricity is pushed out to the grid or how much “regular” electricity is taken in from the grid. It merely indicates the difference between the two — or the “net usage.” One fact about the net meter that everyone needs to be aware of is that the net meter actually runs backward if the system is producing more solar energy than the owner of the system is using at that point in time. 

Bi-Directional Meters

Bi-directional meters have three display screens. One is a test screen where all lights are on. The second screen shows power coming in from the grid, and the third shows power going out from the solar system into the grid. 

Dual Metering

In a dual metering situation, there are two separate meters that do not communicate. The original utility meter continues to show how much electricity is being taken from the utility. This is called the usage meter. A new, second meter measures how much solar electricity is sent to the utility. This is called a production meter or a generation meter. Both meters are tied to the electric company account of the owner of the system.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.

Japan

An outline of Japan’s overall solar market performance

Japan is the world’s 3rd largest economy. Logically, anyone would expect it to be a global powerhouse in matters concerning solar energy. Reports show that the global solar market continues to grow steadily despite the Covid-19 pandemic. In 2020 alone, the global solar capacity stood at approximately 7,604 Gigawatts. What contribution does Japan’s solar market contribute to the total solar production capacity?

Japan’s overall solar market size and production capacity

According to a recent study, Japan ranks 5th  with a solar installation capacity of approximately 82 Gigawatts per year. As a solar installer or industry professional, you must admit that this is an overwhelming achievement especially considering Covid-19 disruptions. Still, Japan’s solar capacity is most likely to improve owing to several factors, including

• Implementation of favorable policies and regulatory frameworks
• Significant contracts and collaborations extended by the Japanese government to local and foreign players in the solar sector
• Good financial support frameworks.

At the moment, Japan is home to some of the world’s leading solar product producers and distributors. That said, it is pretty easy to import or export various categories of solar products to and from the Japanese solar market. The Japanese government has passed favorable regulations and invested heavily in infrastructure, including ports and reliable transport networks. Some major Japanese ports that are worth mentioning include Tokyo, Nagoya, Osaka, and Kobe.
