Guide To Having Solar-Powered Homes In The Philippines


As the world advances, it seems like the environment is getting worse and worse. As responsible homeowners and progressive individuals, we all want to do what we can to help make the world a better place to live in. Fortunately, there are lots of things we can do. Solar power is a great place to start. Using the sun to power our homes presents lots of benefits for the environment and us. In this article, we’re going to discuss the basics of having solar-powered homes in the Philippines.

What are Solar Panels?

If you want to harness the power of the sun, you’re going to need solar panels.

Basically, a solar panel is a composition of specially designed metallic cells that generate electricity when exposed to light, contained in a sturdy framework.

A single unit of this cell is called a PV module. Multiple PV modules make up a PV panel — which is what we commonly see sold individually. You can connect several panels to produce enough electricity to power both an average house and the biggest mansions in the Philippines. This is called an array.

If you want to create solar-powered, modern luxury homes, then you need to know how solar panels work first. In this section, we’re going to explain exactly how.

Solar panels create electricity out of light. This happens because of the way light particles (photons) react with the metals that compose the PV modules. PV modules are typically created out of Silicon, Phosphorus (which makes a negative charge), Boron (which makes a negative charge), and other elements.

Once sunlight hits the solar panels, it starts several reactions that then become a directional current — electricity. This is known as the Photovoltaic Effect.

In order to use this, solar power systems need solar arrays, batteries, inverters, and a charge controller.

Light strikes the solar panels, and the panels generate DC electric current. This electricity is then drawn into the charge controller to ensure that the charge flowing into the batteries doesn’t fluctuate, as this might damage the batteries.

From the batteries, the electricity flows into the inverter to convert DC electricity into AC electricity, which is what most appliances use. You now have a complete solar power system that you can use.

Average-sized luxury homes have enough roof area to gather the required amount of energy to power their homes completely. Smart luxury homes that have plenty of space, on the other hand, can gather excess power in the daylight and store it for use during the night.

In some areas, local power stations have net-metering programs that allow homeowners to sell excess power to the local grid.

Types of Solar Panels in the Philippines


There are three types of solar panels that you can see in the country: thin-film, polycrystalline, and monocrystalline. These types differ in some key aspects, such as cost, efficiency, and design.

Knowing the different kinds of solar panels that you can get can help you make better decisions when installing a solar power system for your luxury homes.

Monocrystalline Panels

A monocrystalline cell has a single crystal made of pure Silicon that can efficiently conduct electricity even in cloudy weather.

Because they are highly efficient (rated at 15% to 20% efficiency), they can remain small while still creating enough electricity, which makes them highly space-efficient as well. If you only have a little space to install the panels, these are the best options. However, they are also the most expensive type of solar panels.

Polycrystalline Panels

While monocrystalline panels have cells made from pure Silicon, polycrystalline panels have cells with wafers made from molded pieces of Silicon crystals.

This design makes polycrystalline panels cheaper than monocrystalline, at the cost of reduced efficiency (13% to 16%). They don’t perform as well in cloudy weather and don’t have a high heat tolerance. Polycrystalline panels also need additional space to create electricity compared to monocrystalline ones.

Thin-film Panels

Thin-film panels are second-generation solar panel designs manufactured to be lighter and cheaper than the two previous solar panel designs. This type of solar panel design is composed of a semiconductor film separated by a light, transparent material like plastic, glass, or metal.

Unlike the previous two designs, the conductors on the thin-film panels can be made of elements other than Silicon, such as Cadmium Telluride (CdTe), Amorphous Silicon (a-Si), Copper Indium Gallium Selenide (CIGS), and Gallium Arsenide (GaAs).

In terms of efficiency, thin-film panels as a whole are a step behind traditional panel designs, with a median efficiency of 11% to 13% compared to the previous design’s 15% to 20% efficiency. However, for lab-controlled tests and individual reports, thin-film panels show a promising future.

For example, the CdTe thin-film panels from First Solar have an efficiency rating of more or less 18%. CGIS panels are rated above 20%, while GaAs panels are rated about 29.1%. Amorphous Silicon panels are rated the least among the lot, with only a recorded efficiency of 12.24% in 2014.

Benefits of Solar-Powered Homes

Now we know what solar panels are, how they work, and what kinds you can get. 

That said, let’s get into what matters: what happens once we do get solar panels on the roofs of our luxury homes? What exactly are we getting once we have solar-powered homes? Brittany wants you to enjoy all the good things, so let’s talk about the benefits.

Helps Save the Environment

The global temperature average has risen by 1° C since the 1880s. You may not think this is much, but this is the global average. It takes huge amounts of heat to warm the entire world by just 1° C. For example, it only took a 1°C drop in global temperature for a Little Ice Age to occur.

This means you can count on the fact that bad things are going to happen if the temperatures keep on rising. Sadly, scientists are saying that it is already happening.

One of the main benefits of solar homes is that they lessen your contribution to carbon emissions. The country’s main source of energy is coal, which is a non-renewable, highly polluting resource.

If you continue to get your energy from local suppliers, they have more incentive to continue what they’ve been doing and less incentive to stop. On the other hand, if you switch to solar power, then not only are you opting out of a highly polluting power source, you’re also lessening the demand for coal power plants.

More than following the three basic Rs, having a solar panel is a bigger step in the direction of clean energy.

Minimize Electricity Reliance

Unless you already have a solar power system of your own, your only source of energy right now is probably your local power source. This level of reliance means that you are entirely beholden to whatever happens to your power supplier.

Summer blackouts because of low dam levels? Power interruptions because of maintenance? A sudden increase in electricity price? Any of these things frequently happen in our country, and you have no choice unless you invest in a solar power system for your luxury house.

With your power supply, you wouldn’t have to rely on your local station. You would be immune to blackouts affecting the rest of the city, and you won’t be surprised by any additional charges made. Your luxury house can be well and truly independent, just like luxury homes should be.

Easily Integratable with other Renewable Systems

Other sources of renewable electricity exist in the country, such as geothermal, biomass, hydro, and wind power. More than that, as efficient as solar power systems have become, they can still fail from time to time, especially in long periods of rain, such as what frequently happens in the Philippines.

If you’re thinking about going for solar power, then you’ve doubtlessly thought about other forms of renewable systems as well, such as wind turbines. The great thing about solar systems is that you can easily combine their use with another system because the system isn’t especially complicated.

All of the systems just have to feed well into a battery source, and you’re all set.

Increase Property Value

Are you planning on putting one of your luxury homes for sale? Then you might want to consider outfitting it with a solar array. 

Research from Zillow has shown that luxury homes with solar panels are fetched for 4.1% more of the price than other regular houses. This percentage can make or break your sale, and you should do well to profit from your endeavors.

If you want more people to buy your establishment, especially during the pandemic, this is something you can try with relatively low costs.

Disadvantages of Solar Panels

Now, owning a solar power system isn’t all just earth-saving and happiness. There’s quite a couple of downsides as well. Here at Brittany, we want you to be aware of potential pitfalls to make an informed decision about future solar-powered homes. Let’s dive right into the disadvantages of solar panels.

Inconsistent Sunlight Availability

One of the main downsides that solar-powered homes may face is the inconsistency of its energy source. In the Philippines, there are times when we feel that the sun has been beating down on us for weeks on end. Then again, there are times when we feel it disappear for weeks as well.

Sunlight availability is not consistent throughout the days and seasons. This means that the amount of energy you’ll be getting can fluctuate if you’re not prepared. Therefore, if you’re committed to having solar-powered homes, you need to plan around that.


Despite being friendlier for the environment, solar power is still pretty inefficient in its current form. As we’ve seen above, solar powers have yet to breach the 25% efficiency hallmark.

To achieve the highest efficiency possible, you’d need mirrors to amplify the sunlight and motors and sensors to make the panel follow the sun across the sky — and even then, it still won’t be 100% efficient.

Roof Damage

Sure, having solar-powered homes is cool and all — but have you considered the potential damage it can do to your luxury homes? Solar panels, especially traditional monocrystalline and polycrystalline ones, are mounted in heavy frames to protect them.

Therefore, you need to properly assess structural matters on your house to make sure that it can carry the weight of whatever solar panel type you use. That, or you can use thin-film panels throughout.
