Traditional Energy Grid vs. Emerging Microgrid with Solar

Before we talk about the emerging microgrid with solar, let’s talk about the traditional energy grid, first. An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. Traditional energy grid has a few stages before the produced electricity reaches the consumers. 

The first stage is Generation.

  • 70% Fossil Fuel
  • 30% Clean Energy
  • Scarce Resource
  • High Capex

Generation is 60% of your electricity bill. Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

The next stage is Transmission.

Transmission is 7% of your electricity bill. The three-phase power leaves the generator and enters a transmission substation at the power plant. This substation uses large transformers to convert the generator’s voltage (which is at the thousands of volts level) up to extremely high voltages for long-distance transmission on the transmission grid. You can see at the back several three-wire towers leaving the substation. Typical voltages for long distance transmission are in the range of 155,000 to 765,000 volts in order to reduce line losses. A typical maximum transmission distance is about 300 miles (483 km). High-voltage transmission lines are quite obvious when you see them. They are normally made of huge steel towers.

The third stage is Distribution.

The distribution of electricity first begins with distribution substations that use “step-down” transformers, which perform the opposite task of the “step-up” transformer. The voltages of long distance transmission are unsafe for people to handle, so these step-down transformers bring the voltage down to safer levels. The distribution grid then connects these substations to the customers that require electricity, ranging from large industrial buildings to small homes. More substations and smaller transformers help to further lower the voltages, and divide the electricity among subdivisions or residential areas. Then, that is the only time the electricity reaches your homes.

Emerging Microgrid with Solar

Emerging Microgrid with Solar

Microgrid is a self-sustained electric power generation, and distribution system that provide electricity service to number of small, remote, and isolated areas that remain un-electrified. They can be fully isolated from the main grid or connected to it but able to intentionally isolate themselves. Microgrid supply remote communities which includes residential households, local businesses, as well as public institutions.

Generation is also the first stage for Microgrid.

DC electricity will be converted to AC through solar inverters, then it’s ready for commercial, industrial and residential consumer use. Sunlight and generation is the only cost for microgrid.

Turn to Solar Energy Now, It’s the Best Time.

Turn to solar energy! – It’s time!

Solar Energy

Turn to solar energy, now! TICK TOCK! TICK TOCK! Did you hear that? That’s the countdown before our non-renewable resources run out. Would you wait ‘till that time comes? Let’s look at the bigger picture. Using fossil fuel hurts the environment and its inhabitants and greatly contributes to global warming.

Solar Energy

Before everything turns dark and gray, here’s the bright solution. We give you the power to stop that ticking clock by switching to solar power which is one of the cleanest, most sustainable and most renewable resources in the world.

Solar Energy refers to energy from the sun. The sun has produced energy for billions of years. It is the most important source of energy for life forms. It is a renewable energy source unlike non- renewable sources such as fossil fuels.

A household rooftop solar panel system can reduce pollution by 100 tons of CO2 carbon dioxide in its lifetime-and this includes the energy it took to manufacture the solar panels. Solar panels can improve future air quality for humans as well as the millions of birds, fish, and mammals that are negatively affected by pollution each year.

The benefits of using less fossil fuels and relying more on natural resources is not only good for you and your family’s financial status, but also the environment. Avoid putting off investing in renewable energy that could improve your community and lower your utility bills.

Solar energy solutions allow you to



while helping significantly reduce the carbon footprint and harmful emissions into the environment brought about by continued sourcing of energy produced from coal fired power plants.

We offer free layout and consultation.

There’s only 6 easy steps on turning to solar energy:

  1. Consultation
  2. Site inspection
  3. Design
  4. Installation
  5. Testing and Commissioning
  6. Turnover and Training

During the O&M Presentation and Training, Mr. Rommel Cenizal, AVP of Asset Management Department, congratulated Maoneng Philippines and its engineers and officers.

I would like to congratulate Maoneng Philippines because even there are a few delays due to the construction of the building, you still delivered in a timely manner. And the way the engineers and installers worked on the installation of the panels and inverters was very professional. – Mr. Rommel Cenizal, AVP of Asset Management Department

Client Testimonial

After the event, Maoneng Philippines was given a chance to have an interview with Mr. Rommel Cenizal, AVP of Asset Management Department. He shared the reasons why they turned to renewable energy and why they chose Maoneng Philippines to be their partner in this Solar Project.

The MPTC Group


Considered the largest toll road developer and operator in the Philippines – in terms of vehicle traffic volume, revenue levels, asset base – and in terms of combined length of expressways in kilometers.

They are a toll road company with three major long-term concessions in the country – with three new concessions under construction awarded to them. MPTC Group broke barriers and ventured to the fast-growing Visayas region, seen as a beginning to creating and building more toll roads in high-growth areas outside of Luzon. They are the first Philippine tollroad company that now has significant stakes in three major infrastructure companies in three progressive countries in the ASEAN region.

Metro Pacific Tollways Corporation (MPTC).

They are leading other industry players in all financial aspects, with a quarter of a billion dollars in revenues based on the latest 2017 figures. Since 2008, their core income has grown by 400%. They hold three operating long-term concessions in the Philippines – namely: the North Luzon Expressway (NLEX), Subic Clark Tarlac Expressway (SCTEX), and the Cavite Expressway (CAVITEX). They hold three more concessions to build, operate and maintain – namely the Cavite Laguna Expressway (CALAEX), the Cebu Cordova Link Expressway (CCLEX), and the NLEX Connector.

On the average, they handle around one million vehicles per day—and still counting. Thanks to an increasing number of travellers who have been encouraged to make journeys more regularly because of high quality roads from the cities to the countryside, and vice versa.

Turn to Renewable Energy – 6 Easy Steps

If you are interested in turning to renewable energy, you might have a lot of questions in mind on what to expect. Here are 6 easy steps in turning to renewable energy.

Turning to Renewable Energy – Step 1: Consultation

Turn to Renewable Energy

If it is your first time turning to Renewable Energy as your main source of electricity, it is important that we talk about your needs and discuss your questions and concerns. We could meet through phone, video call, over some coffee, our office or yours as well.

Turning to Renewable Energy – Step 2: Site Inspection

Turn to Renewable Energy

We’ll pay a visit to check your property and electrical stuff.
We’ll also fly a drone for roof inspection and take photos for the system design.

Turning to Renewable Energy – Step 3: Design

Turn to Renewable Energy

Our team will design a custom solar PV system for free with the goal for helping you reduce if not cancel your electricity grid dependency. Once you sign the contract, our customer care team will start working on the local permits and utility paperwork.

Turning to Renewable Energy – Step 4: Installation

Before installation we will deliver the materials to the site which builds up excitement on the installation. Our workers (installers, electricians, site engineers and site managers) will all be there ready to do the work. The duration of the installation depends on the capacity to be installed.
We will start the installation by preparing the wirings followed by the railings. Once we complete the wirings and railings, that is the time to bring the panels to be attached on the railings. When all the panels are installed, it will be connected to the inverter(s) to convert the DC electricity to AC electricity, the electricity needed to power the house or the building. If you are going to apply for Net Metering, that is what comes next.

Turning to Renewable Energy – Step 5: Testing and Commissioning

Our engineers and electricians will inspect the whole system, from all the panels to the inverters and wirings. This is to check the quality of work and to make sure that everything is up and running and ready for activation.

Turning to Renewable Energy – Step 6: Turnover and Training

Depending on the size of the project, turnover could include a ceremony with simple program and giving of certificates just like the CALAX Solar Project Turnover.

After the turnover ceremony we will train you or your officer(s)-in-charge. We will explain the how to’s of the system. We’ll also provide a project manual. You can always contact us if you have questions even after the turnover.
