The US Department of Energy (DoE) and Masdar are going to collaborate in testing a new special coating material to be used in the PV industry. PV solar installations suffer from numerous handicaps which are a result of real life operation conditions. One of these negative operational factors are moisture and cementation problems which occur on the surface of solar modules. Basically, dust sticks to the surface of the modules, and is glued to the surface with the help of moisture which accumulates as condensation from the surrounding air ("morning dew"), and creates a coating which grows over time reducing the amount of sunlight that gets through to the reactive layers in the solar modules. This significantly reduces PV module performance, and requires constant cleaning of the surfaces, a task that becomes quite a chore when you have to clean hundreds of thousands of modules at a large scale facility.
The Macedonian government (Former Yugoslav Republic of Macedonia) issued a tender inviting bids from developers for 44 smal hydropower projects in this Southeast European country. Water concessions will be awarded based on the design, build, operate and transfer (DBOT) model.
