Solar and Renewable Energy Portugal

Solar Algarve your energy specialist

Solar Algarve started more than 10 years ago on the solar energy market in Portugal. Our company G&DEG Renewable Energy started in 2018 as a merger of 2 companies. Together we have more than 20 years solar energy experience and with our new partners for heating and cooling we have an extra 25 years of heat pump and climatization experience.

We have an International team with English, Dutch and Portuguese specialists. This joint venture makes us specialists in energy neutral buildings. With 25 years of experience in Scotland with heatpumps and underfloor heating and our 20 years experience of solar energy we can offer an integrated heating/cooling and solar solution for your house or office.

Brands and Partners

We only use high quality products and select the brands carefully, so that we maintain a good relationship with the manufacturer. This helps us to provide top quality installations and service to our end clients. Below you will find some more information regarding the brands we use:


Victron Energy has a strong, unrivalled reputation for technical innovation, reliability, and build quality. Victron Energy products are widely considered to be the professional choice for independent electric power. Efficiently combining two or more distinct power sources is what Victron do best. Victron products work perfect together with Fronius Inverters and BYD batteries. This makes our inverters extremely suitable for grid connected battery systems, also called ESS. Victrons products include sinewave inverters, sinewave inverters/chargers, battery chargers, DC/DC converters, transfer switches, battery monitors and more.


A photovoltaic module must last at least 25 years. That’s why we select only raw materials of the highest quality and of traceable origin and we process them in a highly automated way. Our clients’ satisfaction is the best confirmation of the quality of our products. Moreover, we have achieved numerous other independent certifications. FuturaSun work every day to provide our clients with high-performance and long-lasting products.


Renewable Energy Devices Limited (RED) was incorporated by Dr Jason Cassells, with over 20 years’ experience in the heating and water industries, in March 2014, to bring innovation, highly efficient renewable energy heating products and solutions to the marketplace. Providing a cost effective and low carbon alternative to fossil fuelled heating appliances, RED has developed a market leading range of air source heat pumps along with controls, hot-water distribution and storage systems. With the correct heating system design and installation, we can provide 5kW of heat for every 1kW of electric consumed, or in other words, we are 500% efficient.

Our heat pump design started with a blank sheet of paper, rather than an evolution of an inferior air-conditioning system and using our skills, knowledge and experience, we designed a renewable heating solution for both the domestic and commercial sectors of unparalleled performance. Key objectives were efficiency, performance, noise, aesthetics, ease and simplicity of installation.


A passion for new technologies, intensive research and revolutionary solutions have been shaping the Fronius brand since 1945. As the technology leader, we find, develop and implement innovative methods to monitor and control energy for welding technology, photovoltaics and battery charging. We forge new paths, try something difficult and succeed where others have failed in achieving what seems to be impossible. But these are not the only reasons why Fronius is the global leader in innovation and technology. We have a clear vision, an unremittingly inventive spirit and an ingrained sense of quality, so we can keep shifting the limits of what is possible and set the trends that change the market.
