Questions and Answers

It depends on the particular model, other parameters, but our street lamps have an autonomy of 3 to 7 days.

When deciding to install a solar lamp, it is important to pay attention to several key issues:

• The solar lamp should be mounted in a place without artificial lighting (to avoid
• lamps should be placed at a suitable distance from each other so as not to interfere with each other’s work
• It is worth looking carefully at the technical specifications or enlist the advice of a specialist.

Petra Energia specializes in the design, manufacture, supply, installation and commissioning of solar and hybrid lanterns.

The company’s main products are solar and hybrid lanterns, which can be customized according to the individual requirements (needs) of customers.We also invite you to visit our store www.mojaenergia24.plWe also supply components for lanterns such as batteries, charge controllers, light fixtures, photovoltaic panels wind turbines.

A solar lamp is a lighting device that uses solar energy to charge the batteries that power LED light fixtures, eliminating the need to connect to the electric grid.

Solar lamps work by converting solar energy into electricity.
They consist of photovoltaic panels, batteries, charge controllers and LED light fixtures.
Solar energy is absorbed by the panels, stored in batteries, and then used to power the LED lights

The hybrid lamp uses both solar and wind energy, providing reliable lighting even in low sunlight.

(Note: the disadvantage of hybrid lanterns is that the turbine generates noise, which can be a nuisance to residents of houses located near these lanterns)

A fully integrated lamp has a photovoltaic panel, a lithium-ion battery and a charge controller built into the light fixture.
They often have a built-in motion sensor.
They can be used to illuminate areas where continuous lighting is not required.

The disadvantage of these lanterns is much worse autonomy compared to traditional solar lanterns.
Practically in the winter period these lamps do not work.
The advantages are ease of installation and low price.

The “split” type lantern is a “semi-integrated” lantern.
It has a lithium-ion battery and a charge controller (controller) integrated into the luminaire.
Unlike fully-integrated lanterns, the “split” lantern has a higher-power photovoltaic panel with the ability to be directed in a southerly direction.

Split lanterns have much more autonomy than integrated lanterns, can be competitive with traditional lanterns

The benefits of using RES include a reduction in CO2emissions, reduced consumption of conventional energy and lower operating costs. Installing solar and hybrid lanterns eliminates the need for expensive cable lines, and often do not require paperwork such as building permits.

Please contact me in writing at biuro@petraenergia.pl or by phone with Petra Energia’s Sales Department.
Please provide details such as: location, number and characteristics of the lanterns (panel power, power and luminous flux of the light fixture, battery capacity), expected date of completion of the task.

Installation costs depend on project specifications, the number of lamps and installation conditions.

Yes.
Petra Energia usually configures customized lamps to meet individual customer requirements

Yes.
We provide service, maintenance and technical support for our installations during the warranty and post-warranty period.

Typically, the process of installing the lanterns begins with a site visit by a Petra Energia specialist in the presence of the investor.
As a result of the site visit, the locations of the lanterns are determined.
Sometimes a construction project is needed – then it is necessary to take action in this direction.

During the site inspection, attention should be paid to good sunlight in places where lanterns are to be located, as well as to the networks of underground utilities (gas, water, electricity, telecommunications).

When the locations of the lanterns are approved (possibly a construction project completed, building permits obtained) the Petra Energia installation team carries out the installation itself.
