Powered by the sun

Solar photovoltaic (PV) generators convert the energy from the sun into electricity through their solar cells, which are semiconductor-based materials. These solar cells are gathered together to form a solar panel. Each panel can have a peak capacity from 80-200 W, depending on size and technology. Panels can be installed together in order to achieve the desired output capacity.


Almost every location in the world receives solar energy daily, which makes PV technology the first option available for almost all hybrid systems. Small wind or hydro power plants are much more site specific and are suitable for fewer locations.


Insolation (the amount of solar energy received at a specific location) is well known around the globe and does not vary greatly at the local level (unless there is direct shadowing on the structure, which should always be avoided). The long data collection periods required for siting wind or hydro resources are rarely necessary for solar.


Solar PV arrays do not produce emissions or noise, as a photochemical process generates electricity, instead of mechanical devices for absorbing the kinetic energy (as is the case with wind or hydro technologies).

Easy Installation

PV panels are comparatively easy to install and can be set up by local qualified technicians with some training. It is necessary to choose the best orientation of the PV panel structure in order to maximize energy production with respect to the load.

Although the cost of PV electricity is generally higher than energy produced by small wind or hydro, prices for PV panels have been decreasing dramatically in the last few years. These favorable prices exist for the most developed markets in Europe or the US. In developing countries, prices can be substantially higher. This is mainly due to inefficient distribution chains, customs duties and lack of competition.

It is known that purchased materials and services often make up 60-80% of the cost of the product. To ensure competitive pricing, DLRE has strategic partnerships with vendors from around the world to ensure the right equipment are deployed for each project at the most efficient cost.

DLRE develops relationships with partners and suppliers that yield significant benefits for both parties by focusing on each other’s strategic value, economic value, performance and management of risk.
