The correct installation dimensioning is one of the most important decisions to enjoy clean energy. If done well avoid installation problems such as overloads, draining the battery, or spend more money than necessary. There are 5 points to discuss:

1st - Adequacy

It is very important to use devices (bulbs) and low-power appliances (class A). DO NOT USE FILAMENT BULBS. Consume much. Replace with the LOW POWER.
If you choose to use high-drain devices such as stoves, electric, water heater, etc.. connected photovoltaic system / wind, which is not recommended, use them for short periods and NEVER simultaneously. This would avoid having to install a high power inverter and a battery of high capacity, invest more money than really necessary.
Reduce unnecessary consumption, do not leave connected equipment not used. Turn off lights when not needed. AND VERY IMPORTANT: Stand-by equipment (standby) consume electricity, more than you think. Turn them off.

2nd-MEASUREMENT

Make an analysis of all the equipment you intend to use. Use the table provides Celine Power to get the two fundamental parameters that need. Daily consumption and instantaneous maximum power.
Example: energy saving lamp 15 W / hour. It means it consumes 15 Watts per hour. In 10 hours consumes 150 Watts. A kitchen that consumes 900 W / hour. In one hour consume 900 watts. If the lights 20 minutes will have consumed 300 watts. The sum of all devices is switched by the time you are turned on will be daily consumption. The sum of the power of all devices simultaneously lit gives maximum instantaneous power.
Daily consumption will indicate the level of generation that needs and determine the maximum instantaneous power inverter power.
Suppose as an example that consume energy for 5 Kw a day and at a certain point we need a power of 2.5 kW. These values are normal in a house of average size.

3 º GENERATION

You must generate a higher percentage than what is consumed to offset losses and inefficiencies of the various devices. As a general rule should generate at least a third more than it consumed.
The specifications for generating photovoltaic panels and wind turbines are the best conditions of sun and wind. There are databases that show the actual values of each location. The location of the panels will also affect performance.
Celine Power photovoltaic panels provide 185 W per hour. Depending on the geographical area and the month of the year will have more or less photovoltaics. In Spain, on a mid-latitude (40 °), as an annual average, 4 panels of 185 W can provide about 3 kW per day.
A wind turbine ANGEL 400 provides 400 Watts per hour wind. Assuming minimal wind for 12 hours a day the wind turbine to provide us 400 × 12 = 4800 watts (4.8 kW per day).
In these conditions would have generated 3.0 + 4.80 = 7.8 kW. Sufficient for the sample measurement.

4th-ACCUMULATION

The battery capacity is measured in amperes / hour. The energy that accumulates are the amps by the voltage. Suppose a battery of 500 Amp / hour and 24 Volt. The energy that theoretically we could deliver are 500 × 24 = 12,000 (12 Kw). In practice, depending on the battery type we get, supposing at full load, 80% of the total.
We have to size the battery for the time we want to cover without generation. Keep in mind that if the installation of photovoltaic panels is just only have generation when it is sunny. 10 hours at most in summer. In these circumstances therefore would need to cover a minimum of 14 hours. If the installation is hybridized (panels + turbine) without generation times are much less, so you would need a smaller capacity battery. Covering a range of 24 hours is a very reasonable practice. In our example, with a consumption of 5 kW per day, using a battery of 200 Ah at 24 V, (200 × 24 = 4800 Watts), we would have almost a day of autonomy. Keep in mind that during the night, usually consumption is the lowest for the entire day.

5th CONSUMPTION

The inverter is the team that converts the direct current generation and batteries into alternating current for feeding housing.
Must be of the "sine wave" to avoid problems with any of the equipment supplied.
The efficiency of this equipment is over 90%, when working near its maximum rated power. The less power prompted, the lower its efficiency. We must therefore select an inverter with a maximum slightly above the maximum instantaneous power. In our example would install March 1 Kw. These teams are designed to withstand higher power for a short period of time.
