Whether it’s solar panels, inverters, or mounting structures, we ensure that all components come from reputable, top-tier manufacturers within the solar energy industry.

How does a solar power system function?

Solar panels convert sunlight into electricity, which can be directly used to power your household appliances. If your system produces more energy than you need, any surplus power is exported to the utility grid, and you will be compensated for it.

How will a solar power system affect my utility bill?

By producing your own solar energy, you can significantly lower your electricity bills. The actual savings depend on your consumption and the system size. Contact us to get an accurate estimate of your potential savings.

What is the lifespan of solar panels?

Solar panels are designed to last for at least 25 years, with manufacturers guaranteeing their performance for this period. All solar panels installed by SSPI come with a minimum 25-year power warranty, and 1-year material and workmanship warranty.

How can I monitor the energy produced by my solar system after installation?

Our solar systems come with real-time performance monitoring software, which you can easily access from your computer or mobile device, allowing you to track energy generation at any time.

Does SSPI provide battery storage options?

Yes! Solar Systems Philippines Inc. offers various battery storage solutions. Contact us to get an accurate battery storage applicable to your home and business.

How should I maintain my solar power system?

Solar power systems are typically maintained twice a year. The primary tasks include cleaning the solar panels and checking electrical connections. Our maintenance service is optional, and pricing is based on the system size. A detailed cost estimate will be provided in your free quotation.

What is Solar Photovoltaic (PV)?

Solar Photovoltaic (PV) refers to technology that converts sunlight into electricity. Unlike Solar Thermal systems, which use the sun’s energy to heat water or air, Solar PV systems generate electricity, making them a more applicable and efficient option for powering homes and businesses.

What are the benefits of switching to solar energy?

Switching to solar energy can help reduce your electricity bills, decrease your carbon footprint, and provide a reliable, renewable source of power. Solar systems also increase property value and offer energy independence, protecting you from rising electricity prices.

How much roof space is needed for a solar panel system?

The amount of roof space required depends on the size of your solar system and your energy needs. On average, a 5kW solar system requires around 30 to 35 square meters of roof space. Our team will assess your roof’s suitability during the consultation to ensure the optimal placement.

Will my solar panels work on cloudy days or during the night?

Solar panels will still generate electricity on cloudy days, though their efficiency will be lower compared to bright, sunny days. However, they do not generate electricity at night. To make use of energy after dark, you can either store energy in batteries or rely on the grid.

How much does it cost to install a solar system?

The cost of installing a solar power system depends on factors such as the size of the system, your location, and the type of components used. Our team can provide you with a free quotation based on your specific needs, including all costs involved in design, procurement, installation, and commissioning.

Are there government incentives or rebates for installing solar panels?

In some regions, there may be government incentives, rebates, or tax credits available to encourage the adoption of solar energy. These incentives can reduce the upfront costs of installing a solar system. We can help you navigate available programs in your area to maximize your savings.

Can solar power systems be installed on all types of roofs?

Most roof types can support the installation of solar panels, including pitched, flat, and even commercial roofs. During the initial consultation, our engineers will assess the condition and suitability of your roof to ensure it can safely support the solar system.

What happens if my solar panels get damaged or stop working?

Solar panels are built to be durable and long-lasting, but in the event of damage or malfunction, they typically come with warranties covering repair or replacement. Eigen Energy ensures that all installations come with manufacturer-backed warranties, giving you peace of mind regarding performance and longevity.

Can I install solar panels if I live in an apartment or high-rise building?

Yes, it’s possible to install solar panels on apartment buildings or high-rises, though there may be additional considerations such as permissions from building management and space limitations. We can explore other solutions like solar sharing or community solar programs, depending on your building’s setup.

How long does the installation process take?

The installation of a solar power system typically takes between 1 to 3 days, depending on the system size and complexity. After installation, the system will undergo a thorough testing phase to ensure it’s functioning correctly before it’s fully commissioned.

Is it possible to expand my solar power system in the future?

Yes! One of the advantages of solar systems is their scalability. If your energy needs increase, you can add more panels or expand the system with additional components such as inverters or batteries. Our team can help you plan for future expansion during the initial design phase.

Do I need to clean my solar panels regularly?

While solar panels require minimal maintenance, cleaning them once or twice a year to remove dust, dirt, and debris can improve their efficiency. If you’re in an area with heavy rainfall, cleaning may not be as necessary, as rain can naturally wash away dirt.

What is the difference between on-grid and off-grid solar systems?

An on-grid system is connected to the utility grid, allowing you to export excess energy and draw from the grid when needed. An off-grid system, on the other hand, operates independently of the grid, relying on battery storage to supply power when solar generation is insufficient, such as at night.

How does solar energy help reduce carbon emissions?

Solar energy is a clean and renewable energy source that produces no greenhouse gas emissions during operation. By switching to solar, you reduce your reliance on fossil fuels, which helps lower your carbon footprint and contribute to a more sustainable energy future.

What is Net Metering, and how does it work?

Net metering is a system where excess energy produced by your solar panels is sent back to the grid, and you receive credit for it. When your system isn’t generating enough power, you can draw from the grid without additional costs, thanks to the credits accumulated during times of surplus generation.
