Ever wondered about the difference between monocrystalline vs polycrystalline solar panels? When you evaluate solar panels for your photovoltaic (PV) system, you will encounter two main categories of panel options: monocrystalline solar panels (mono) and polycrystalline solar panels (poly). Both types of panels produce energy from the sun, but there are some key differences monocrystalline vs polycrystalline solar panels. […]
What is a pure sine wave inverter?
April 13, 2020
FAQ
A pure sine wave inverter is an electronic device that converts direct current (DC) to alternating current (AC). A sine wave is a continuous wave that describes a smooth repetitive oscillation. Conventional AC power is produced by rotating machines and is mathematically described as a sine wave. It is the ideal waveform for the transfer […]

What is a half-cut cell mono PERC solar panel?
December 17, 2019
Article
What is Half-Cut Cell? Half-cut cell mono PERC solar modules have solar cells that are cut in half, which improves the solar module’s performance and durability. Traditional 60-cell and 72-cell solar panels will have 120 half-cut cells and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses […]
The solar panels lifespan
October 12, 2019
Article
Solar panels lifespan typically come with 20 year warranties that guarantee that the panels will produce at least 80% of the rated power after 20 years of use. Solar panel manufacturers put a lot of effort into making their solar panels robust. They need to be able to withstand heat/cold cycles and heavy weather. However, […]

Hybrid Solar Systems
October 12, 2019
Article
Hybrid solar systems combine the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage. If you own a grid-tied solar system and drive a vehicle that runs on electricity, you already kind of have a hybrid setup. […]
Off-Grid Solar Systems
October 12, 2019
Article
An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied. For homeowners that have access to the grid, off-grid solar systems are usually out of question. Here`s why: To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator (if you live off-the-grid). […]
Grid-Tied Solar Systems
October 12, 2019
Article
Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept – Grid-Tied Solar Systems that is connected to the utility power grid. Advantages of Grid-Tied Solar Systems 1. Save more money with net metering A grid-connection will allow you to save more money with solar panels through better […]
Transformerless inverter for solar PV system
September 26, 2019
Article
What is a transformerless inverter? Transformers The differences between standard or conventional inverters and transformerless inverters are: Conventional inverters are built with an internal transformer that synchronizes the DC voltage with the AC output. Transformerless inverters use a computerized multi-step process and electronic components to convert DC to high frequency AC, back to DC, and […]
Isolation transformer
September 26, 2019
Article
An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in […]
Home Power Protection: Generators vs. Uninterruptible Power Supplies
September 23, 2019
News
As we enter the summer season, the likelihood of weather events such as thunderstorms or even hurricanes increases significantly, along with the chance of power failures that often accompany such events. It’s a good time, then, to assess options for home power protection in the event of a failure, including battery backup systems, also known […]
