During the preparation of documentation, each installation is verified on the basis of invoices and electricity readings at 15-minute intervals. On this basis, we define the power profile and demand.

Yes, but such an installation should be made using structures dedicated to this type, it can cover – ballast structure or welding.

The least problematic are wooden, reinforced concrete or monolithic roofs due to the permissible additional load

An environmental approval is required prior to construction commencement . This document is issued by: Woda Polskie, Sanepid, RDOŚ and the Sanitary Inspection.

It is also necessary to have the building conditions as well as the connection conditions and the connection design. In this regard, expert knowledge is required for this application and design works prepared in advance.

The construction of the investment cannot begin without the possession of a construction design and a building permit.

Yes. This is absolutely one of the most important implementation points. The reason why it is necessary is that each case is different. During the on-site inspection, we check, among other things, the structure of the data or the place of connecting the installation to the network.

We also encourage you to check our subpage What kind of land for PV farms? in which we describe the detailed requirements for land for PV investments.

• Test of earthing resistance and equipotential bonding,
• Tests of DC circuits,
• Test of open circuit voltage VOC DC,
• Test of the current of the ISC DC short-circuited circuit,
• Testing the insulation resistance of AC and DC LV circuits,
• Testing the current-voltage characteristics of strings of photovoltaic modules,
• Thermal imaging camera tests of electrical connections, photovoltaic modules
• junction boxes, etc.
• Cutting grass (ground),
• Washing photovoltaic panels,
• Measurement of the tightening torque of modules, structures and cables in transformers, inverters and
• and distribution boxes,
• Topping up transformer oil (if necessary),
• Checking fire fighting equipment.

The warranty periods are determined by the manufacturers of the components used. The warranty period is as follows:

• For photovoltaic modules, under the terms of the manufacturer’s warranty, a 12-year warranty
• for the mechanics and 25-year line warranty for the power.
• For the inverters, according to the producer’s warranty conditions, 5-year warranty.
• For perforation of the assembly structure, in accordance with the terms of the manufacturer’s 10-year warranty.
• For other components, in accordance with the manufacturer’s warranty terms.

If there are no extraordinary circumstances, no more than twice a year

According to the contract for the performed construction works, Helios provides a warranty for a period of 2 years from the date of signing the Final Acceptance Protocol.

Building your own PV installation brings many advantages and benefits, the most important of which, in our opinion, are:

• Improving the energy efficiency of the company.
• Independence from growing energy prices.
• Conscious and responsible Environmental Friendly Company.
• Return on investment in 4 years, then pure profit.
• Long lifetime of the panels up to 25-30 years.
• Maintenance-free installation.
• Smaller variable premiums from the distribution part.
• Reduction of peak peak power consumption, which may lead to the possibility of reducing the contracted capacity.
• Environmental protection and reduction of CO2 emissions, reduction of your carbon footprint

The benefits of operating such an installation, assuming the purchase price of energy at the level of PLN 450 / MWh, amount to approximately PLN 450,000 per year for the purchase + additional PLN 150,000 for distribution minus maintenance costs.

It is worth noting that the roof-mounted installation has lower maintenance costs due to the lack of the need to mow the grass or protection, and amounts to about PLN 50,000 per year.

The annual cost of maintaining the installation on the roof is PLN 50,000.

The cost of the installation on the ground is PLN 110,000 per year. Here are added elements such as lawn cutting, monitoring, security, real estate tax, lease.

An average of 15 kg / m2 for a flat roof – in the case of ballast concrete block structures. For a pitched roof, an average of about 13 kg / m2.

Yes, absolutely, you can. Please visit our subpage What about the energy

In the case of availability, it is possible.

In business, this period is about 4 years, but taking into account the soaring energy prices and additional fees – for example, the power fee, this period is still shortening.

At Helios, we approach the subject comprehensively, providing solutions, not problems. Therefore, we take care of all formalities.

Helios Strategia has been operating since 2007. Since 2017, we have been actively involved in the sustainable development of solar energy in Poland.

So far, we have built on a turnkey basis power plants with a total capacity of over 450 MW. As subcontractors, we have built installations with a total capacity of 1 GW.

So far, we have made 39 installations in Poland. Their number is constantly growing.

It all depends on many factors, for example the number of skylights, lightning protection systems, chimneys and air conditioners. Very generally, it can be assumed that to obtain 1 MW of power, you need from 14,000 m2 of roof.

The construction time of such an installation is approximately 3 months on average.
