Solar Photovoltaic energy is a recyclable source of energy obtained by the conversion of luminous energy in electric energy. Not to confuse with solar heating, that possesses the beginning of completely different operation.

How does it work?

For we could use the energy that comes from the Sun, we needed three elements basically: the photovoltaic modules, the load controllers and the batteries. Siemens photovoltaic modules are built starting from tablets of monocristalin silicium, material of superior quality to the similar ones and with high efficiency. Siemens is world leader in production and technology of production of photovoltaic modules, being the only company in the world that possesses the technology Powermaxä / TOPSä .

O second element, the load controller, is a device of fundamental importance to preserve the batteries, increasing its useful life. Siemens offers a complete line of controllers of load of last generation. The batteries are the elements that you store energy. With their aid, the consumers can use at night or in periods of bad time the energy irradiated in days of sun.

Why Solar Energy?

Because it is a clean energy, not poluente, reliable, rational, that doesn't request maintenance and it doesn't consume any fuel. For those reasons, it can be used in countless applications. In Brazil, where we are privileged for the Sun, thousands of facilities exist for rural electrification, electric fences, bombeamento of water and telecommunications that you/they use Solar Photovoltaic Energy.

Is Solar photovoltaic energy expensive?

Along the last 20 years, the cost of the Solar Photovoltaic Energy dropped in a spectacular way. Nowadays, for the great majority of the applications, it is gotten to pay the investment fact in about two years, or less.

Why Siemens Solar Photovoltaic Energy?

Because Siemens is world leader in the production of solar modules, having already produced about 150MW in photovoltaic modules. Siemens is a company that constantly invests in technology, always seeking the consumer's satisfaction and the excellence of its products. In Brazil they were already sold more than 50 thousand photovoltaic modules for the most several applications in the most remote places.

FAQ

1 - Can I use a solar panel without the battery?

Yes, the solar panel generates energy directly of the sun and it can ignite a lamp or to work a motor without the use of the accumulator of energy (I support of batteries). however the systems of residential energization need the battery to accumulate the energy produced during the day that will be used even during the night. The use of the solar energy starts then to be constant and continuous being avoided heatstroke variations as soon as it affects the acting of the installed equipments.

2 - Does some limitation exist for the use of the system of photovoltaic solar energy?

The user of the system of solar energy needs to be before anything else a to be conscious and disciplined. The autonomy of the system is directly related to the total of energy generated during the photo-period (in Ah or Wh) and the total consumption newspaper of the installed equipments. You cannot consume more than it is being generated daily, under feather of discharging the bank of batteries along a certain period.

3 - In cloudy or rainy days, does the solar system work?

What transforms the solar spectrum in energy it is the intensity of the light, when the day is of cloudless sky the panel it is producing 100% of its capacity. When the heatstroke decreases of intensity, he/she is also reduced the generation capacity. Even so, even in cloudy or rainy days the panel Siemens generates energy.

4 - How many days of autonomy I can totally have in case of period rainy, for serial days?

When we projected a Solar photovoltaic system, we took in consideration the daily consumption, to calculate starting from there the amount of energy to be generated by photo-period (day), this allows an autonomy of 6-8 days (in most of the cases). You cannot consume more than this being generated daily, under feather of working with a deficit that will discharge the battery in a certain period.

5 - Increasing the amount of batteries, is there also an increase in the capacity of my system?

Not necessarily, what does with that its system increases it is the total of Wp to be generated, the capacity of its system grows in agreement with the amount of installed panels (total in Wp), as this growth it can be modulavel, you cannot starting from an only panel to go joining other little by little until reaching the total demand of its system.

6 - Does the installation of a solar system need to be made by a specialized technician?

You same it can install its photovoltaic solar system, as long as it follows the constant instructions in the user's manual. Being the whole careful so that the positive polarity (+) negative (-) it is not never inverted in the connections. Consult the electrician's manual that you will receive with its equipment and in case of doubts he/she enters in contact with us, we will have great satisfaction in serving them.

7 - which is the useful life of a panel Siemens?

The panel Siemens will be active for about 40 years, with total covering of Warranty for 25 years.
