FAQ

1. How do solar panels work?

​

Solar panels convert sunlight into electricity using photovoltaic cells. When sunlight hits the panels, electricity is generated and converted by an inverter into usable power for your home or business.

​

2. Do solar panels work on cloudy days?

​

Yes, solar panels still produce electricity on cloudy days, although at a reduced efficiency. They do not require direct sunlight to function, only daylight.

 

3. How much can I save on my electricity bill?

​

Savings depend on your energy consumption, system size, and electricity prices. Many households reduce their electricity costs by 30–70% or more.

 

4. How long do solar panels last?

​

Most solar panels have a lifespan of 25–30 years or longer. Their efficiency gradually decreases over time, but they continue to generate electricity well beyond their warranty period.

​

5. Do solar panels require a lot of maintenance?

​

No, solar panels require very little maintenance. Rain usually keeps them clean, and occasional cleaning may help maintain optimal performance.

 

6. What happens to the electricity I don’t use?

​

Excess electricity can be fed back into the grid or stored in a battery for later use, allowing you to maximize the benefits of your solar system.

​

7. Are solar panels cost-effective in our climate?

​

Yes. Modern solar technology is highly efficient, and even in varying climates solar panels are a cost-effective and sustainable energy solution.

 

8. How long does installation take?

​

Installation typically takes 1–3 days, depending on the size of the system and site conditions. The entire process from order to activation is usually quick and straightforward.

​

9. Do I need planning permission to install solar panels?

​

In most cases, planning permission is not required. However, regulations may vary depending on property type and location. We help you check what applies in your area.

 

10. Do solar panels increase property value?

​

Yes, installing solar panels can increase property value by making the home more energy-efficient and attractive to buyers due to lower energy costs.
