Automatic Photovoltaic Cost Calculation
The cost calculation automatic photovoltaic system is a necessary process for selecting the appropriate system. First you need to calculate your electricity needs (how many kilowatt hours per month you will consume) and decide what percentage you want to cover them from the autonomous photovoltaic system you want to get. Indicatively an average Greek house with solar water heater and energy saving lamps but also with the use of air conditioning, oil burner and electric stove, consumes about 350-450 KWh month (cost about 40-45 euros). Consumes without electric stove and air condition about 250-300 KWh.
To produce 250 KWh per month from photovoltaics about 12 180 watt photovoltaic panels are required each with batteries and accessories. Together with the installation, the cost today reaches approximately 8.000 to 10.000 euros, depending on the batteries that will be used.
If the house has no connection to PPC at all, we have to invest in a larger system or in a hybrid system with a wind turbine (if the point is appropriate) to have a few days of autonomy in case of intense and continuous for cloudy days. A fuel generator is also useful in these cases for cases of continuous continuous sunshine. The generator will only be used for a few hours each morning to charge the batteries until there is more sunshine.
If again we have a connection with PPC then in these cases there is a switch in the network for electricity from PPC. Alternatively we can install a NET METERING system so the use of batteries is not considered necessary and the total cost of the system becomes much cheaper.
System Selection-Autonomous Values
The choice of system and technology is based on the conditions of the application site and the requirements on power quality and reliability. In Greece, the most probable renewable sources that can be utilized are solar and wind, due to the high sunshine and the strong winds that prevail in the country, without this excluding the utilization of energy from other sources such as geothermal, biomass and small hydroelectric this is possible.
In the event that biomass or geothermal energy is used for electricity generation, the exploitation of the heat energy produced during the conversion is a serious economic advantage. In terms of topology choice, the second topology has development. It will soon be refined and there will be units on the market that can be integrated into the system with small interventions. The first topology is the one that is widely applied, but it is an expensive solution due to the high prices of DC and current components.
Storage of electricity in batteries is the weakest point of the system (poor efficiency, maintenance and replacement). An alternative is the construction of a pumping station, the operation of which is based on the pumping of water, in cases of low loads, from one tank to another located at an altitude difference and the efficiency of energy when appropriate. An important element in the design of the system is the control unit. The optimal way of energy management contributes, among other things, to the better utilization of RES, to the quality of the provided power and to the increase of the life of the system.
Applications in Greece - Price of Autonomous
Greece presents remarkable conditions for the development of autonomous systems for the following reasons:
• high levels of sunshine and high wind potential in many areas
• existence of many island or other remote areas that
characterized by a lack of electricity or as environmental
sensitive areas (archeological sites, etc.)
• use of conventional methods of electricity generation
(diesel generators) in island areas With high maintenance costs
and environmental pollution
• increase of electricity production through RES (especially autonomously
photovoltaic systems) during the period with the highest demand (summer)
In Greece today there are applications that supply electricity to households with RES, such as that of the island of Gavdos. There are also a significant number of stand-alone systems for electrifying individual homes or other buildings that use similar technology. For the Small Islands of Greece, most of which are not connected to the national grid, the use of energy by autonomous photovoltaic systems is the most sustainable solution.
