Our History
Ceiba Renewables was founded in 2008 with the purpose of making a positive contribution to the environment and society through the installation of clean energy systems. Everything that we do stems from our founding purpose, from the selection of the products we install to the level of service and advice we provide to our customers, our focus is on delivering environmentally-friendly, long-lasting, high performance installations.
From 2008 to 2011 we were involved in solar thermal and small-scale hydro projects. As the solar PV market began to grow we adapted our knowledge from grid-connected hydro to solar PV and since 2010, solar PV has accounted for 90% of our business with other technologies such as Voltage Optimisation, G59 Testing and consultancy work accounting for the rest of our work.
A family-run business, we have deliberately kept ourselves small which has allowed us to adapt to the peaks and troughs of the volatile renewables industry.
While many in the solar market have decided to compete on offering the cheapest price, we have often seen installations where sub-standard products and installations mean that customers end up paying for additional maintenance and replacement parts well within the expected lifespan of the system. These parts are often manufactured for cheap financial cost but high environmental and social cost which contradicts the key point of switching to clean energy. For those reasons you will have a slightly higher initial capital cost on a solar system from Ceiba Renewables, however you will gain much more in the long-term.
Our aims for the future are to maintain a steady organic growth and bring high quality solar power to many more homes and businesses across Scotland.
Trees For Life and Tree-Nation
Our commitment to the environment is our number one priority. For every installation we complete we make a donation on behalf of our customers to these great organisations:

Tree-Nation is a non-profit organisation that allows citizens and companies to plant trees all around the world and offset their CO2 emissions. They are involved in more than 100 reforestation projects and have managed to get around 13000 hectares reforested. Every time we buy a Tree Nation Certificate, we help local forest communities around the world keep a specific forest standing and help 85% of all terrestrial species living in tropical forests, whose existences are intrinsically bound to the forests or their habitat.

The core purpose and vision of Trees for Life is to restore the Caledonian Forest and all its constituent species of flora and fauna to the Scottish Highlands. They aim to provide a powerful and educational experience that will promote the work of restoration to wider audiences. Through providing a demonstration of the techniques of ecological restoration, we aim to inspire similar projects elsewhere in the UK and around the world.
