Economic potential – solar energy and photo cells
Sun is the main source of energy on Earth. The developed and developing technologies can be applied to a wide variety of applications. The increase in their CUA makes them economically viable.
Introduction of a technology for utilization of solar energy in company has the following advantages:
Direct use of solar energy
When solar collectors are installed, hot water cost are greatly reduced.
Solar PHV systems are also a valuable addition to wind generators in hybrid autonomous electric systems.
Opportunity for application in the urban environment
The natural site for installing these types of systems is on the roofs and facades of buildings. They do not take up a lot of space in this way, and they are the most appropriate type of RES technology for densely populated regions.
Low operational expenditure
After the initial investments for introduction of these systems, there are no costs for fuel purchase, and the maintenance costs are minimal.
Available state subsidies and preferences for their installing
The major obstacle for most companies for introduction of solar systems is the high capital costs. Subsides for their purchase are granted in many countries and the manufacturers are offered preferential purchase prices if their system is connected to the national grid. For example, up to 3.50 euro per watt is refunded to the company in Holland .
Low capital costs of the passive solar systems for heating.
The most appropriate devices to be used just for heating are solar collectors, because their capital and operation costs are the lowest.
“Tandem cell” technology is an opportunity to supply hydrogen fuel cells in vehicles.
Hydrogen is an alternative to fossil fuels and the technology will enable each company to produce its own fuel for its vehicles
