The subject of the project will be the purchase and assembly of: 546 photovoltaic installations, 1365 solar installations and 89 air heat pumps within a single-family dispersed building, together with the work necessary for the operation of the said equipment. Each solar system designed and constructed shall secure the energy required to heat the water for each household at a minimum of 55 per year. The number of solar collectors to be installed and the capacity of the hot water tank shall provide at least 50 litres of hot water per person per day with a temperature of 50 to 60 °C. Photovoltaic modules must have attested to the quality control authority confirming that the modules offered have undergone tests according to IEC procedures confirming their full compliance with the scope of PNEN 61215, PNEN 61646, PNEN 60891, PNEN 60904, PNEN 617302 and PNEN 61829 standards. All devices should have up-to-date tests and approvals for use in our country. The mounting of the cells must be made of non-corroding and non-corrosive material and must be authorised for use by the panel manufacturer. The photovoltaic set shall ensure proper interaction with existing electrical installations. The contractor must ensure that the PV installation is installed so that there is no blackout of the panels otherwise the optimisers are applied.
