Solar PV Panels

Most solar panels are designed to last 25 to 30 years, but they may continue to produce electricity beyond this period, albeit at a reduced efficiency. After about 25 years, the typical panel’s efficiency may decrease by 10-20%.

• Monocrystalline panels are made from a single crystal structure, offering higher efficiency (typically 15-20%) and a longer lifespan. They tend to be more expensive.

• Polycrystalline panels are made from multiple crystal structures and are generally less efficient (around 13-16%), but they are more affordable.

Yes, solar panels can still generate electricity on cloudy or rainy days, although their efficiency may be reduced compared to full sunlight. Panels can still capture indirect sunlight and convert it into power, but output will be lower than on clear, sunny days.

No, solar panels do not produce electricity at night because they rely on sunlight to generate power. However, if you have a solar battery storage system, you can store the excess energy produced during the day for use at night or during cloudy periods.

Yes, installing solar panels can increase your home’s value. Homes with solar systems often sell faster and at a premium price, especially in markets where energy efficiency is highly valued. The value increase varies depending on location and other factors.

The cost of installing solar panels varies depending on the size of the system, type of panels, installation complexity, and location. This can vary based on your region and specific requirements.

The amount of energy generated by solar panels depends on factors like:

• The size of the system (number of panels).
• The efficiency of the panels.
• Sunlight exposure: The amount of direct sunlight your location receives.
• Roof orientation and tilt: Panels installed at optimal angles will produce more energy.

For example, a 1 kW solar system can generate between 3 to 5 kWh of energy per day, depending on the location and sunlight availability.

To determine if your home is suitable for solar panels, consider:

• Roof size and orientation: A roof with enough space and good exposure to sunlight (ideally facing south in the northern hemisphere or north in the southern hemisphere) is ideal.
• Roof condition: Ensure the roof is in good shape to support solar panel installation.
• Shade: Avoid areas with heavy shading from trees or buildings.
• Electricity consumption: The more energy your household consumes, the larger the solar system you may need.

A battery is not required, but it can be beneficial. Batteries allow you to store excess energy generated during the day for use at night or during cloudy weather. Without a battery, any excess energy is typically sent back to the grid (in grid-tied systems) or may go unused in off-grid systems.

Solar panels require minimal maintenance. Key maintenance steps include:

• Cleaning: Panels should be cleaned occasionally to remove dirt, dust, or debris. This is especially important in dusty or dry areas.
• Inspecting: Regularly check for any damage, loose wiring, or obstructions.

Professional service: Consider having a professional technician inspect and maintain the system every few years.

If a solar panel gets damaged (due to hail, falling debris, etc.), it may need to be repaired or replaced. Most solar panel manufacturers offer warranties (usually 10-25 years) that cover defects or significant performance issues. However, physical damage from weather events may not always be covered, depending on the warranty.
