1. Photovoltaic systems
   a. grid connected
are the systems that are connected to the grid and the output from the photovoltaic panels goes directly to the grid. No need for batteries for storage ! The Goverment either pays for this amount of electriicty a standard amount per kwh, or with the "net metering" what is consumed is summed with what is produced in one invoice ! 
If you have roof or place to set up one grid connected system is he best investment of money today !   
   b. autonomous systems
are the systems that are not connected to the grid, at least not directly.
Batteries are needed for storage of the electricity during the day and use it during the night or days with not enough sun. The batteries add to the total cost about 35% and if used properly can be usefull for as many as 15 years. Proper use of batteries mean that in a usual every day cycle  (even with the deep cycle special solar batteries), we do not use more than 50% of the battery power.   
   c. Solar Tracking Systems
are systems that use a special sun tracking device. This special mechanism adds 30-40% more output than the traditional fixed can find below some examples

DT1500 1500
Mecasolar  Tracker  20kw

2. Hydro Generators
are systems that use the power of a river (running water) and make it electricity
in remote areas that no sun or wind can be reached.  

3. Wind Generators
are systems that use the power of the wind and make it electricity

4. Hybrid Systems - Hybrid Power Systems
Hybrid systems typically include some combination of PV, wind, and diesel generators, along with controlling electronics and battery storage. The reasons for these systems include making maximum use of the available resources (wind and sun), serving critical loads (telemetry and communications), and supplementing existing equipment (reducing the duty cycle of an existing diesel generator).

6. LED lamps : with the use of these lamps instead of the usual Halogen lamps one can save up to the incredible 90% . One 6w GU10 LED lamp can readily replace one 50w halogen thus minimizing the consuption 50/6=8,33 times . In other words using 10 new LED lamps in a place (office,etc) that must be on for 8 hours per day can spent 8,33 times less money and save per year the incredible amount of EUR 321,00. The cost to buy these 10 pcs of 6w GU10 LEDs are less than half  of this amount, so in 5-6 months your investment pays back !! And the new leds have shelf life of 50,000hours !
available chromatic light of the LED lamps are white, yellow warm yellow.the white color delivers 30% more light for the same wattage.
You can find LEDs  to fit in any fitting like GU10, MR16 Flourescent Lamps ,E27, E14 etc .LED LAMPS.pdf
7.Solar pumps
Water pumping: PV systems can replace hand pumps or large engine-powered water pumping systems. In many pumping systems, no batteries are required, as the pumped water storage provides that function. we can deliver solar pumps that can pump water from 350 meters deep.
