Solar PV FAQ: A beginner’s guide to solar PV

Q1. What are solar panels?

Solar panels are devices that convert sunlight into electricity. They generate renewable energy that can be used in homes, offices, farms, and other environments.

Q2. Why install solar panels?

Solar panels provide several key benefits:

Energy independence
Generate your own electricity and reduce reliance on the grid. When paired with energy storage, excess power generated during the day can be used at night or during outages.

Lower electricity costs
Using self-generated electricity helps reduce utility bills, especially during peak hours.

Stable long-term returns
In Taiwan, surplus electricity can be sold back to the grid under government programs, offering a stable return on investment.

Sustainability and ESG value
Solar energy reduces carbon emissions and supports net-zero goals, while also strengthening ESG performance and brand value.

Property value enhancement
A well-designed solar system can increase property attractiveness and long-term value.

Q3. How are Richten Energy’s colored PV panels different?

Our colored PV coating technology allows full customization of panel appearance while maintaining power generation efficiency.

Compared to conventional panels, our solution offers:

• Reduced glare and reflection

• Self-cleaning surface

• Improved durability with anti-soiling and scratch resistance

This enables solar panels to integrate more naturally into different environments.

Q4. Can my property install solar panels? Is the process complicated?

Most properties with sufficient sunlight exposure—such as rooftops or open spaces—can install solar panels.

We evaluate site conditions, including orientation, available area, and structure, to design a suitable system. Installation is typically completed within a few days, and financing or leasing options may be available to reduce upfront costs.

Q5. Can solar panels really reduce electricity bills?

Yes. By using electricity generated during the day, you reduce the amount of power purchased from the grid.

Savings vary depending on system size and usage patterns, but the impact is especially significant for commercial spaces with higher daytime consumption.

Q6. Do solar panels only work during the day?

Solar panels generate electricity during daylight hours. However, when combined with energy storage, stored electricity can be used at night.

Even on cloudy or rainy days, panels can still generate power, although at reduced efficiency.

Q7. Are solar panels environmentally friendly?

Yes. Solar energy produces no direct emissions, air pollution, or water contamination.

It plays an important role in reducing carbon emissions, lowering reliance on fossil fuels, and supporting long-term climate goals.

Q8. Are solar panels durable? How long do they last?

Solar panels are highly durable and typically last 25–30 years or more.

With no moving parts, maintenance is minimal. Regular cleaning and periodic inspection are sufficient to ensure long-term performance.

Q9. Where can solar panels be applied?

Solar PV systems can be used in a wide range of applications, including:

• Residential and commercial power generation

• Agricultural applications (e.g., irrigation and lighting)

• Remote or off-grid power supply

• Transportation infrastructure (e.g., signals and lighting)

• Community energy systems

Q10. What other applications does solar energy have?

In addition to electricity generation, solar energy can be used in:

• Solar water heating

• Solar street lighting

• EV charging support

• Solar-powered agriculture

• Portable and off-grid energy solutions

Applications continue to expand as technology advances.
