Environmental friendly relying on a free source of energy Reduces fuel costs and provides positive return on investment. an be 100% reliable by utilizing conventional systems as secondary backup for the solar system. Easy installation and maintenance.

Installing a solar system is possible for new construction projects and retrofits (existing buildings). Solar solutions are more effectively introduced during the design stage for maximum return on investment.

Yes some solar systems, especially thermal can operate in the winter season when sunlight is available, and especially with backup assistance. The performance and output of the system however, will vary from summer to winter depending on the sun's intensity.

Depending on the type of project, application and the price of conventional energy, the system can return its value on investment with a relatively short period. In some cases, the payback can be immediate whereby the installed cost of solar might be lower that conventional electric heaters (for example). The payback period and return on investment is usually calculated in Millennium Energy Industries proposals and offers. It is important to mention that the MENA region is merited with high solar energy that can be utilized in different applications.

Solar systems are usually easy to install and maintain, and depending on the project size and phases, installation can be done in one day, or several weeks, or months. Millennium Energy Industries offers submit a project implementation schedule that is agreed with the customer prior to implementation.

The solar space heating system usually occupies between 20-30% of the roof space assuming the building is a one story building; for other applications (steam, cooling and photovoltaic) Millennium can provide an initial estimate of space required accommodating the project needs during the initial feasibility study for the project. In all cases, Millennium Energy Industries team usually inspects the place prior to propose.

Insolation is a measure of solar radiation energy received on a given surface area in a given time expressed in kilowatt-hours per square meter per day (kW.h/(m2.day).

Flat Plate Solar Collectors: Flat plate System is designed with a well insulated, waterproof box containing a dark absorber plate under one or more translucent or transparent covers. Water passes through pipes located below the absorber plate.

Flat plate collectors can be very efficient in hot and sunny climates, although they do not have insulating benefits of the evacuated tube (below) that affects their performance in colder sunny climates.The Evacuated Tube Solar Collector. These collectors have multiple evacuated glass tube which heat up solar absorbers and, ultimately, solar working fluid in order to heat hot water or for space heating. The vacuum within the evacuated tube reduce conducted heat losses, allowing them to reach considerably higher temperatures than most flat-plate collectors.


For this reason they can perform well in colder conditions. In recent years the production volume of evacuated tube has exploded, resulting in greatly lower manufacturing and material costs. The result is that evacuated tube are now similar in price to flat plate, but with the insulating benefits of the evacuated tube, they are set to become the default choice for thermal solar applications worldwide.A difference in evacuated tube over the flat-plate type is that the constant profile of the round tube means that the collector is always perpendicular to the sun's rays and therefore the energy absorbed is approximately constant over the course of a day. Due to the high temperatures that can occur in evacuated tube, special system design considerations are made to avoid or mitigate overheating conditions.

Concentrating Collectors. Concentrating collectors are utilized to achieve temperatures in the range of 100-200 Degrees Celsius for industrial and commercial application where steam, district heating or cooling, and power may be required. The collectors are usually parabolic troughs that use reflective/mirrored surfaces to concentrate the sun's energy on an absorber tube containing heat-transfer fluid, or the water.
