Example C:  "Normal country house"
1 fotovoltaic solar panel of 110 W costs aproximately between:

1 stationary battery** of 12 V 100 Ah costs more or less:

1 regulator (protector of the battery) of 12 V 10 A costs more or less:

1 inverter APS de 300 W 110 V AC costs between:
(The APS transforms the direct current DC in AC,so you can connect any (small) normal equipment for 110 V AC)

We don´t calculate instalation costs, because it´s easy to install:

Total of investment for this system is between:
4 lamps, 1 radio, 1 television
The daily average consumtion is:

1 panel of 110 W produces with 3,5 hours sun/day:

For the energy generation you need:


You have to store (12 V system) la quantity of:

You need the quantity of stationary bateries  12 V 100 Ah (without reserve):

You need the quantity of stationary bateries  12 V 100 Ah (with a 1 day* reserve):

You need the quantity of stationary bateries  12 V 100 Ah (with a 3 days* reserve):

There are different types of stationary accumulators or batteries with different plates and electrolites:

low mantainance, open.

free mantainance with valves.

free mantainance with gel.

other special types .
Average life expectancy of accumulators depending of the model and trademark:

  5 to   6 years

  4 to   5 years

10 to 30 years

Life expectancy of  solar panels
There are different tipes of solar panels different materials of cells and qualities:

Life expectancy of  the best solar panel trademarks are between 25 and 30 years. Please review the especifications of each trademark and model.
The reserve of the solar system is calculated on the base of your geografical position: There are places where it rains during three or four days consecuently, so you need a minmum reserve of three days.
It also depends if the service of the system has to be garantized, like for example in comunications, medical equipment, etc..
We recomend to increase step by step the instaled bateries, view also Sostainability.

The average daily sunhours could be found in tables for your region.

You multiply the panelpower 110 W with the average daily sunhours 3,5 h/d = 385 Wh/d.

You divide your daily energy needs 400 Wh/d by your daily panel energy 385 Wh/d = 1,04 panels.

You divide your daily energy needs 400 Wh/d by your system voltage 12 V = 0,33 Ah battery capacity.

You divide your needed battery capacity 0,33 Ah by the capacity of one battery 100 Ah = 0,33 batteries.

You multiply the quantity of batteries with the reserve factor 2 for 1 day of reserve = 0,67 batteries.

You multiply the quantity of batteries with the reservefactor 4 for 2 days of reserve = 1,33 batteries.
