Misconceptions about the impact of weather on Solar modules

Aug , 31 2021

Despite solar energy becoming more accessible and a more common method for powering homes, offices; there are still plenty of people out there who believe the misconception that solar panels only work in parts of the country where the weather is sunny and agreeable year-round. Solar energy is far more adaptable than some people think, especially when it comes to production in variable weathe...

What is PERC technology on Solar modules

Sep , 01 2021

Solar cell technology is evolving and improving continuously. PERC cell technology is also one of those new technologies that helped solar modules to perform with better efficiency and performance. What are PERC solar cells: PERC can stand for either Passivated Emitter and Rear Cell or Passivated Emitter and Rear Contact. At its core, a PERC solar cell is simply a more efficient solar cell, meanin...

How to implement battery monitoring in a deployable product?

Nov , 27 2021

Standalone ohmic battery monitoring systems designed for data center application are not suited for a genset environment. Although ohmic monitors work, they are expensive (estimated at $2,000 for a 24-volt system), time-consuming to install, and require trained personnel to interpret their data output. To achieve widespread adoption in the genset market any battery monitoring technology will need ...

NiCd versus Lead Acid Starter Batteries for Generator Systems

Dec , 10 2021

Apart from a few special applications that use mechanical cranking, such as spring starters, the greatest percentage of generator set systems utilize 12-volt or 24-volt starter motors. For prime power and standby applications, the two most commonly used battery types are lead acid or nickel cadmium (NiCd). This article discusses the differences between NiCd and Lead Acid starter batteries for gene...

How long do solar batteries last?

Jan , 17 2022

There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

What are the soft costs of datacenter?

Jul , 22 2022

Data centers can’t afford to go dark. That’s why reliable critical power systems arecentral to their operation. Selecting and maintaining these systems comes at a price, but astronger understanding of “hard” and “soft” costs -- and what can be done to mitigate thelatter -- can protect the bottom line. Hard and soft costs vary from one operation to the next. In general, hard costs refer to the expe...

How to lower the soft cost of Data center

Aug , 01 2022

Outages are a major fear for data centers. And for a good reason. Unfortunately, many companies still roll the dice by purchasing critical power systems,assigning someone internally to keep tabs on the equipment, and simply hoping the system comes through when it needs to. (Spoiler: it often doesn’t.) Scarce resources, a lack of skilled personnel, and increased edge computing (and the scattered fa...

Power Factor and Harmonic Analysis in Single phase AC to DC converter

Aug , 15 2022

Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part ofmost of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC toDC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is used ...

Why battery energy storage moving to higher DC voltages (Part-1)

Nov , 08 2022

Today, most utility-scale solar inverters and converters use 1500 VDC input from the solar panels. Matching the energy storage DC voltage with that of the PV eliminates the need to convert battery voltage, resulting in greater space efficiency and avoided equipment costs. The evolution of battery energy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Woo...

Are lithium-ion batteries in energy storage systems reliable?

Dec , 05 2022

The most common type of battery used in energy storage systems is Lithium-ion batteries. Lithium-ion batteries allow you to take electricity generated by the grid, solar panels, wind turbines, or any combination and store it for use when you need it most. However, not all lithium-ion batteries are the same when it comes to reliability and safety. Even though they are referred to generically as one...
