Solar Energy FAQs

What is a solar panel?
A solar panel is a device that absorbs sunlight and converts it into electricity. Solar Panels convert sunlight into electricity with the use of photovoltaic or solar cells. These cells are arranged in grid-like patterns that make up most of a panel's body.
How can solar panels generate energy?
According to Prosolar International, solar panels collect electrical charges from sunlight. This collected energy is then converted to usable power by an inverter. Solar panels are typically mounted on roofs to maximize light exposure.
Why should we install solar panels?
Solar panels help foster a cleaner and healthier environment by using a practically unlimited resource like light energy in a process that involves almost no pollution. It's cheaper, more efficient, and much more sustainable than regular power.
Are solar panels a good investment?
Yes! The initial investment might be a bit steep, but a full panel set-up could see returns within five years due to power savings that could range from Php 200 to as high as Php 10,000 on average, according to Solaric Philippines.
Does the shift to solar energy come with financial incentives?
In a Rappler feature, Mike De Guzman, a Filipino resident, revealed considerable savings on energy costs since he started using solar panels in his home. On top of direct savings, MERALCO also has programs in place to resell surplus energy back to the main grid under the Renewable Energy Act. In the daytime, MERALCO pays P7.50 per kWh and in night time P3.50 per kWh under its Peak/Off-Peak (POP) pricing scheme.
How much can we save if we shift to the use of solar panels?
According to Philippine Solar Power Adventure Inc., solar panels allow you to produce your own clean electricity with solar energy. This saves you Php 200 to Php 10,000 for the first year alone. You should see savings from Php 10,000 to Php 50,000 or more over the next 25 years depending on your solar setup and household power usage.
Can solar panels power an entire household?
Solar Panels can be the sole provider of energy for the entire household if you opt to use an off-grid installation. However, in this case you should consider getting good reliable batteries for power storage. In this kind of installation, you don’t just lessen your power consumption. You actually also earn in return.
How do solar panels help the environment?
The use of solar energy greatly reduces fossil fuel emissions, subsequently limiting pollutants and carbon dioxide that go to the atmosphere. Furthermore, with the use of solar panels, you will be using less fossil fuel each and every day, and producing your own non-polluting power and pure energy from the sun.
How long can solar panels last?
Solar panels come with warranties that last up to 20 to 25 years, more than enough time to recoup costs from the initial installation.
What are solar panels made of?
According to Lorentz Solar Panels, a solar setup is typically made up of sturdy aluminum frames, advanced ethylene vinyl acetate (EVA) encapsulation, and triple layer back sheets.
How much do solar panels cost?
The prices of solar panels vary according to their watt peak capacity (Wp). For Solaric Philippines, prices range from Php 33,000 to Php 496,000. The cheaper option with the 25 W Micro Grid Tie can provide enough electricity for a medium sized refrigerator and can save Php 480 a month while the more expensive option with the 5000 W Grid Tie can provide electricity to a household that uses two or more major appliances, earning savings of about Php 8,000 per month.
Does the government offer subsidized solar panels?
The Philippine government offers home improvement loans through the PAG-IBIG fund, giving members an opportunity for them to reduce their electricity bills by going into renewable energy.
What other organizations offer loans?
Companies like Solaric Philippines offer bank financing for larger projects 100k Wp and above. The terms vary depending on the end user's credit rating and their relationship with the bank.
What kind of maintenance do solar panels require?
Solar panels are solid state and require little maintenance since there are no moving parts. Once or twice a year, the panels should be cleaned to remove debris and/or dirt that may accumulate.
Do solar panels have warranties? How long?
Yes. All solar panel manufacturers are required to offer warranties. Companies like Pro Solar International Inc. offer terms good for as long as 20 years for panels, and five years for inverters. Terms may vary across different manufacturers.
What are the usual problems with solar panels?
The panels may not collect enough energy on days where the sun is obscured by cloud cover, though they’ll still produce significant energy. The system is also a bit less potent at night, which is why a battery is needed to collect energy at daytime.
How are solar panels installed?
The panels are mounted on a roof or yard and then connected to an inverter, which is mounted near the main panel. This is where Direct Current (DC) is converted to Alternating Current (AC).
How long does installation take?
According to United Solar, the installation process typically takes a day.
How much space do you need for a solar array?
The company installing the panels would have to conduct an ocular inspection of your property before deciding on which works best for your needs and the available space.
How do solar panels work in low-light conditions?
According to Mel Maniego of Prosolar International, solar power is still a viable option for typhoon-prone areas like the Philippines and locations with cool, cloudy climates. There are at least five continuous hours of sunlight per day on average, and this is enough to provide significant returns in energy expense, especially if your house is equipped with a battery.
Do I need a solar battery in my home?
While it is possible to not have a battery in your solar panel system, having one allows you to have a more consistent stream of power at night and in low-light conditions like storms, having already stored surplus energy from brighter days.
Where do I get solar batteries?
You may ask an authorized representative from your preferred solar company for backup power options.
How do I secure my solar array if I reside in a storm-prone area?
You may ask an authorized representative from your preferred solar company for backup power options. The overall resilience of your solar panel system would depend on the build quality of the actual manufacturer, and how the engineers fix it on your property. Roof-mounted arrays may need some reinforcement if the end user’s area sees a lot of harsh wind and weather activity.
Will going solar help lessen my carbon footprint?
Solar energy has a very low carbon footprint, and the processes involved in generating power do not involve the burning of coal or other non-renewable materials.
Should my community look into solar energy?
Solar panel systems are generally more effective when the arrays have a wider surface area. Coordinating with the local government and members of the community will help lower energy costs for everyone.
