About US

ES-3 Ltd. specialises in the construction of solar PV systems and the trade in all necessary components.

What we do and why?

Our company was established in 2010, when solar PV systems were being constructed entirely for investment purposes. Even then, we decided to focus our efforts on smaller systems in order to design and offer solutions that make green solar PV energy available to a wide range of consumers – for the home and business, for investment purposes or for own consumption.

In the last 10 years our team has gained valuable experience and knowledge so that today we can offer our clients the best possible system, at the best possible price and which, most importantly, is fulfilled at the highest possible quality.

Today we hold over 200 items in stock at competitive prices which we offer on attractive terms. And we expand on our range of products every day!

The Process

Althought quality comes first for us, we don’t underestimate the value of the time it takes for one solar PV system to be designed and constructed. We are prepared to offer our clients support at every step along the way:

Comprehensive consultation
We will answer all of your questions and we will strive to make every detail, at every step of the process clear.
Design
Once we have discussed all details regarding the solar PV station with you, it is our turn to present it in a technical manner which is presribed by all relevant instituions and follows all relevant standards and guidelines.
Maintenance
Each solar PV system requires different maintenance. We remain at your disposal for any issues. During the warranty period, you are entirely absolved of any maintenance costs of the equipment.
Documentation
The construction of on-grid systems is linked to a lot of documentation but this should not scare you! We will accompany you on every step of the process and we will complete the necessary forms.
Construction
After all other stages have been passed, you can sit back, relax and let us do the work. We will complete the construction at a high quality standard and within agreed timelines.
