Solar panels reduce electricity bills, provide clean, renewable energy, and lower carbon emissions. They also increase property value, offer energy independence, and may qualify for tax incentives or rebates, making them a smart long-term investment.
Most solar panels last 25 to 30 years or more. While their energy output may slightly decrease over time, they continue to produce electricity efficiently for decades with minimal maintenance.
Savings depend on your energy usage, location, and system size, but on average, homeowners can save up to 50–80% on their monthly electricity bills. Over the system’s lifetime, this can amount to hundreds of thousands of rupees in savings.
Yes, solar panels still work on cloudy days—though with reduced efficiency. They can produce 10–25% of their normal output depending on cloud cover. If your system includes battery storage, you'll still have power when the sun isn’t shining.
The actual installation usually takes 1 to 3 days, depending on the system size and roof type. The full process, including approvals and inspections, may take 1 to 3 weeks from start to finish.
No, typical rainfall does not damage solar panels; in fact, rain helps clean them and can improve efficiency by washing away dust and debris. However, extreme weather events that accompany heavy rain, such as floods or high winds carrying large debris, can cause damage by dislodging panels or impacting their components. Regular professional inspections by solar panel companies in Sri Lanka are recommended to ensure the seals and mounting systems are intact, preventing water infiltration and structural issues. For reliable maintenance and installation services, you can trust Roofmart Solar.
If your electric bill is high despite having solar panels, it’s likely that your energy consumption exceeds the capacity of your solar system. This can happen during the day or at night. Remember, once the sun goes down, your solar panels stop producing power. Choosing reliable solar panel companies in Sri Lanka like Roofmart Solar can help ensure your system is designed to meet your energy needs efficiently.
Home solar panels can significantly reduce your electric bill, but you'll likely still receive one, even if it reads zero in some months. Choosing reliable solar panel companies in Sri Lanka like Roofmart Solar ensures you get clean energy and consistent savings month after month.
To clean solar panels, first turn off the system for safety. Next, rinse the panels with a garden hose to remove loose dirt. If more cleaning is needed, use a soft-bristle brush with a solution of water and mild soap (or a vinegar/water mixture). Scrub gently, then rinse thoroughly, and use a squeegee to remove excess water and prevent spots. For reliable service, Roofmart Solar is one of the top solar panel companies in Sri Lanka that can assist with proper cleaning and maintenance.
