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.

Nigeria

Solar Market Outlook in Nigeria

With a population of 200 million and an economy that relies mostly on its oil reserves, the economy of Nigeria is highly volatile. Add to that Nigeria’s electricity woes. Many residents and business owners in the country rely on generators to power up their business and even then a huge percentage of the population has no access to electricity. 

Experts agree that this shouldn’t be the case as this is a tropical country. Geographically, its location close to the equator means that it has mostly sunny days throughout the year. The government is hoping that this renewable energy source could be the solution they’re seeking to combat the electricity woes that have haunted them for decades.

The National Renewable Energy and Energy Efficiency Policy in Nigeria was established in 2014. This policy details that Nigeria has a target of 20% electricity generation from renewable sources, mostly solar, in an effort to address the nationwide electricity shortage. They are also hoping to encourage more private investments in solar power plants.

There is notably a high solar potential in Nigeria, which gets up to 7 hours of sunlight daily. If this sunlight can be harnessed, it will produce 333,000 MW of solar power, which should be more than enough to bridge the electricity gap in the country. 

Solar Energy Equipment Supply Capacity in Nigeria

Just as solar power plant projects are limited, there is also limited availability in local manufacturers of solar equipment in Nigeria. For those looking to make solar installations, you can turn to online or global suppliers and distributors for that. 

Top Major Seaports & Logistics in Nigeria

Transporting and logistics handling of solar equipment into Nigeria should be easy since there are plenty of commercial ports available such as

• Lagos Port Complex,
• Calabar Port Complex,
• Delta Port,
• Rivers Port Complex,
• Tin Can Island Port, 
• the Onne Port.
