Best MPPT Solar Charge Controllers in 2023

MPPT solar charge controllers are popularly used for small-scale solar systems, not exceeding 2kW. These solar system accessories are usually pocket-friendly, and their voltage ranges between 100-150V, typically manufactured for solar systems with 12V or 24V batteries. However, you can use many of them on 48V batteries as well.
This article will discuss some of the most commonly used solar charge controllers. You can find more solar charge controllers on this Solar blog. These accessories usually have built-in …

What Is a Solar Charge Controller?

A solar charge controller (also known as a regulator) is identical to a traditional battery charger. Its function is to manage the solar charging process to ensure that the battery is effectively filled or, more critically, not overloaded. While solar charge controllers come in a wide variety of budgets, supply voltage, and functionalities, there are two major types: PWM and MPPT solar charge controller units. PWM variants are less complicated, utilizing a switch between the solar plant system and the storage devices. We will dive deeper into the difference later in this article.
Various battery kinds are supported, much like with any standard battery charger. Normally, the absorption and float voltages are selectable. In addition…

As the industry of solar energy prepares for the decrease of ITC World, asset owners and developers are searching to enhance their pipeline, and now…

Power and Renewables Summit 2020

The coronavirus pandemic has unprecedented effects on the global economy since the aftermath of World War 2. As the world enters the battle and now has a decent fighting chance with the recently rolled out vaccines from different manufacturers, energy stakeholders might have been asking crucial questions such as: “Will decarbonization of the US grid be accelerated or decelerated during the battle against COVID-19 pandemic?” and “How can the pandemic affect the project returns for wide-ranging development of renewable energy systems across the US?”
Beyond the crucial questions revolving around the speed at which energy systems will become ‘renewables-centric’, C-level executives and their utilities, comprehensive …

Grid Edge Innovation Summit 2020

Grid Edge Innovation Summit is a 4-day virtual conference that talks about the different and recent innovations used in the electric grid and what can be expected in the near future. The presentations are likely to be data-intensive in which notable companies at the forefront of the energy sector will handle the preparations.
The topics can be diverse and deep. These include data analytics, artificial intelligence usage, virtual power plants or VPPs, DERMS, and more digital tools. One main point of the discussions will be how those things mentioned can enhance further the resilience and flexibility of the grid.

What Is Going On With China’s Crazy Clean Energy Installation Figures?

After China announced their official 2020 report on their figures in solar and wind system installations, plenty of analysts cannot believe what they have witnessed. According to China’s National Energy Administration, or NEA, the additional capacity for renewable energy systems is in a whopping total of 120 Gigawatts, which is an unrealistic number.
Given the circumstance in 2020 where China has been the epicenter of the COVID-19 outbreak, achieving numbers beyond what all expected is simply impossible to happen. The official predictions by International Energy Agency and other entities won’t even exceed 50 Gigawatts on either renewable energy source.
Experts are surprised with the numbers on solar energy but it is …

The Pandemic Rages On: Some Solar Companies Are Still Selling Door-To-Door

If you think that selling cleaning items and encyclopedias are some of the most common items to be sold using the door-to-door method, then maybe a solar vendor has yet to knock on your door. Vivint Solar has been practicing door-to-door selling in order to attract potential buyers to their rooftop solar panels.
There is a challenge in the technical explanations but it turns out to be very effective. As the company is gaining momentum, the COVID-19 pandemic happened and the global economy is the biggest casualty. New rules and regulations impose restrictions on any social interaction, and that includes door-to-door selling.
Vivint Solar and another large vendor, Sunrun, have joined forces and confirmed that they are …

Bloom Energy Sees Future in Hydrogen Fuel Cells Electrolysis and Carbon Capture

Due to the 4th quarter sales surge, Bloom Energy’s profitability target is projected as a year earlier. The annual deliveries of fuel cell increase to 132.6 Megawatts. Together with the effort of reducing cost, K.R. Sridhar, CEO of Bloom Energy, sees that 2021 will be the best year yet for the company.
Although the progress is consistent, Sridhar is expecting to fully adapt the company’s solid-oxide fuel cell technology. This technology aims to generate electricity from hydrogen. The plan was to obtain ‘green’ hydrogen through electrolysis and capture carbon in ‘blue hydrogen’ coming from natural gas. With this, the estimates will appear off the charts as the impacts are on a very large scale.
Bloom Energy …

Vestas Launches the Largest Turbines in the World as Big 3 Competition Ramps Us

The 3 largest wind turbine companies in the West, namely GE, Siemens Gamesa, and Vestas, have been in constant competition with one another over the supremacy for the wind energy sector’s 3 factors of revenue: offshore, onshore, and services. It only takes one technology strategically introduced in order to propel either company into the top spot.
Siemens Gamesa has undergone a recent change in leadership in the offshore department. Their current priority is sticking to what the offshore unit is best at and replicating it in multiple areas. Acquiring the company Senvion is a power move that aims to close the gap of competition with Vestas in the services revenue.
Leading the race in the onshore department is Vestas. Its …

How US Grid Operators Plan To Tackle Energy Storage at Gigawatt Scale

The amount of power supplied by batteries from renewable energy systems to the grid is expected to raise at least tenfold by 2030. In the US alone, currently, the batteries are responsible for 1.5 Gigawatts of electric power. As the world is shifting more on renewable energies, the challenge for storing energy at a Gigawatt scale seems to be occurring.
Batteries are necessary components in renewable energy systems and a great help to the grid for adjustability corresponding to the energy demand. The more systems are installed, the greater is the demand for storage.
That is why during the Energy Storage Association policy forum last week, representatives of independent system operators (ISOs) and regional transmission …
