Frequently Asked Question

Common Question

Solar panels usually work very well on any roof, whether it is, SW, SE, or South. Solar panels typically work the best when facing south, but if you install them facing West or East, they will still perform well.

You can install solar panels on the land or the roof. If you are purchasing an eight-panel solar PV, then the required space will be 3-bed semi. Usually, for residential purposes, the recommended solar panel is 8-panel Solar PV.


Does the solar panel need to receive constant sunlight from working?

Not at all, the solar panel will consume solar energy during the day, and when at night they work optimum at 10ºc. What you need to know is that if the solar panel becomes too hot, they will become inefficient.

Will my solar panels come with any warranty or guarantee?

Yes, certainly. Your solar panels will come with a manufacturer’s guarantee/warranty. We understand that when you purchase solar panels, you would like to be sure that you are buying robust solar panels and to make sure that we are with you even after you are done purchasing with us, we offer proper warranty/guarantee on the panels.

How long will the solar panels last?

It is only the inverter that you might have to move, other than that no other parts are moving parts, because of which you can expect the solar panels to last for up to 25 years. At the same time, the inverter will last for up to 10 years.

How long will it take to install the solar panels?

It depends on the number of solar panels you would like to install. However, installation should be completed within a day’s time. Scaffolding will be erected at least two days prior before our team arrives at your location to install solar PV. Once we arrive, we will begin mounting the panels on the roof; after that, we will install the inverter, for the final step, we will do the internal wiring.

Will I have to clean the solar panels?

The good thing about solar panels is that they get cleaned on their own if you position them at 15 degrees. But we recommend our clients to inspect the solar panels once every year and rinse it whenever they find it extremely necessary. There are window-cleaning companies as well, who can clean these solar panels for you. If you want, you can get in touch with window cleaning companies as well.

Is maintenance and on-going service required?

It is highly recommended that you get in touch with us once every two years for maintenance services. We offer affordable maintenance packages that you can choose from.

Will the solar panel work even if there is a power cut?

If there is a power cut, then it will switch off your inverter as well, which means power generation function from your solar panels will be stopped as well. However, if you wish, we can easily install a back-up system for you, which will let you use solar energy even if there is a power cut.
