Photovoltaic panels opinions. Before installing photovoltaic panels on your home, you need to know how much they cost, what is the amount of money you can receive from the state, what is your monthly consumption, how much does a photovoltaic system produce and which system suits you best .
Photovoltaic panels through Casa Verde 2024
Regarding the financing available for the installation of photovoltaic panels, it is important to note that, recently, the Government announced that in 2024 a new session of the Casa Verde Photovoltaic Program will take place.
Through this program, natural persons can benefit from state funds in the amount of a maximum of 20,000 lei (about 4,000 euros) to install photovoltaic panel systems with a minimum power of 3 kW (kilowatts) for the production of electricity necessary for own consumption and delivery of the surplus to the national energy system.
One of the conditions to receive this amount is that the beneficiary has an own contribution of at least 2,000 lei.
At the same time, it is important to know that the program is addressed only to those who stay at home. Blocks of flats (ie buildings with shared ownership and individual ownership) with more than two flats are not eligible.
Photovoltaic panels opinions – price
The prices of the panels vary depending on the power of the system (3 kW, 5 k W, 8 kW, 10 kW, etc.) and the services included in the package (transportation, installation of the panels, assembly, grounding, preparation of the prosumer file, assistance, etc.).
Some of the cheapest photovoltaic panel systems are the 3 kW ones, with prices for such a system (without other associated services) starting from around 9,000-10,000 lei. If you opt for a photovoltaic system with a lower power, for example 2 kW, you will not be able to benefit from government funding.
The higher the power of a photovoltaic kit, the higher the price. Here and here you can read two detailed articles about the prices of photovoltaic panels.
Photovoltaic panels opinions – monthly consumption
One of the essential aspects that you must know before installing a photovoltaic system, regardless of whether it will be on-grid (connected to the public grid, it injects unconsumed electricity into the grid) or off-grid (with batteries that store the energy produced remaining unconsumed, to be used later), you need to know what your monthly electricity consumption is.
In this way you will know if you will register a surplus of electricity that you will be able to sell to the network. On the other hand, maybe you have a high monthly consumption, and the photovoltaic system you were thinking of installing does not cover all your electricity needs.
Consumption can vary quite a bit from one house to another depending on the electrical and household appliances used (for example, if air conditioning is used or not, if heating is done electrically through heat pumps, etc.). For example, the consumption for a typical house can be 300 kWh / month, but the variations can be large from one case to another.
Photovoltaic panels opinions – production
Depending on the monthly electricity requirement, you will know what power the photovoltaic system you will install must have. The amount of electricity produced by the system varies not only depending on its power, but also on the geographical location.
For example, according to calculations made by ZoneTec Solar specialists using a computer made available by the European Union, the same 5 kW on-grid photovoltaic kit, with panels mounted on the roof, facing south and east, will have a different output of electricity depending on the location where it was installed.
How many kWh does a photovoltaic system produce?
In Bucharest, the 5 kW photovoltaic system will produce 6,144 kWh per year, which means that it will produce, on average, 512 kWh per month. The lowest productivity will be in the winter months, in December and January (around 250 kWh / month), and the highest in the summer months, July and August (around 715 kWh).
In Constanța, the same system of photovoltaic panels with a power of 5 kW will produce 6,322 kWh in a year, i.e. 178 kWh more than in the Capital. The average monthly production will be 526 kWh per month.
So, if your home, for example, has an average monthly consumption of 250 kWh, it is possible that a 5 kW photovoltaic system has too much power for your needs, and it is better to opt for one with a lower power.
Photovoltaic panels opinions – maintenance
Regarding the costs associated with a photovoltaic system, it is important to know that solar panels also involve costs after installation. So the initial investment in kit, transport, installation, grounding, prosumer file (if applicable) and technical support is not the only cost.
For optimal efficiency, solar panels need maintenance. If they are not cleaned and washed, their efficiency decreases and so does the production of electricity. It may also require repairs, replacement of parts or routine inspections.
For example, according to the FotoSolar company, the price for washing a photovoltaic system with a power between 0 and 10 kW is 360 lei, and for one of 11-20 kW it is 625 lei. According to experts, solar panels do not need constant cleaning, but the removal of dust, dirt or other deposits is sometimes necessary, especially during periods without precipitation.
Photovoltaic panels reviews – lifetime and depreciation
Photovoltaic systems have the great advantage of having a long lifetime. Also, despite the maintenance costs, the initial investment is the biggest cost.
However, you must be aware that the time until the full amortization of the investment is quite long. Some calculations show that the investment pays for itself in 5-6 years, while others speak of an even longer amortization of 10 years. The duration depends, of course, on the initial investment, on the typical electricity consumption of the household, but also on the price of electricity (which is currently capped, but it is possible that in a few years the Government will remove the cap).
In any case, if you pay, for example, 200 lei per month for the electricity consumed, and you have invested 20,000 lei in an off-grid photovoltaic system, the system would pay for itself in about 8 years (without taking into account other costs, such as maintenance costs, etc.).
As the manufacturer Viessmann shows on the official website, solar panels represent a long-term investment, because the average life of a high-performance photovoltaic system is 25-30 years. Thus, if it is properly cared for, the owners can end up saving 3-4 times its price, the quoted source notes.
