Solar Power FAQs

If you have made the decision or are thinking about making the decision to go solar, then you may be wondering - how does sunlight actually get turned into electricity? You may have other questions too, such as will your solar panels work on cloudy days, and will your panels work at night via moonlight, which, after all, is reflected sunlight? To find out the answer to these questions and a few more, please read on.


How do solar photovoltaic (PV) panels work?


What are the financial benefits of solar energy?

How do I know if solar is right for me?

Well, living in Spain, sunny days is not a problem, with an average of 320 days of sunshine a year, solar is definitely right for you.

Can solar panels work by moonlight?

No, the sunlight reflected by the moon is too weak to generate any solar power. Your system will still power or at least partially power your home at night, as most systems come with a battery that stores some of the electricity generated during the day to be used at night.

Do clouds and rain affect solar panels?

Solar Panels not only harness direct sunlight when the sky is clear, but also the diffused light when the sky is overcast. The brighter it is outside, the greater the output of the modules – regardless of whether the sun can be seen directly or not. Rain actually helps to keep your solar panels operating efficiently by washing away any dust or dirt.

How many panels will I need?

Solar PV panels vary greatly in efficiency. The panels we use generate between 100-300 watts, therefore it is not how many panels you need but how much power you need.

How much will solar panel maintenance cost?



On-grid, grid-connected or grid-tied means connected to the utility electrical grid. Off-grid refers to systems that are not connected to the utility electrical grid.
