Products and Services

Here's what we can do for you


We do grid-connected PV (photovoltaic) solar system installations. That means that the system is connected to the electricity grid. Any excess power that is produced will be sent back to the grid. We specialise in residential as well as commercial systems and use only industry leading solar panels and inverters ensuring the best performance and power output at all times.


We check and repair the following components: Inspect panels for defects including fractures, moisture penetration, and frame corrosion. Check operation of all isolators and circuit breakers for correct polarity. Checking of fuses. Checking and replacement of faulty inverters. Safety check including checking of damaged or worn components.


Ecokleen Solar is our strategic partner for the cleaning of solar panels. Debris like dirt, dust, grime, bird droppings etc. can prevent sunlight from entering the solar cells, therefore reducing your solar panels’ capacity to perform efficiently. We suggest you maintain a regular cleaning programme. They also offers thermal inspections to see if your panels are operating properly.
