Just as it doesn't matter what power, rpm, and speed we choose for a car, as these all influence the quality of driving and the price of the vehicle, when choosing a solar panel system, we must also consider the characteristics of the site, our possibilities, and the goals to be achieved with the investment, because these primarily determine the price of the solar panel system.
The financial implications of installing a solar system are determined by several factors: size , power, quality of panels, type of inverter, and the price of other accessories – such as a battery purchased to store the generated electricity. When using the solar panel price calculator, we must also include the cost of design, construction, obtaining permits and future maintenance. When considering the price of a solar panel system, we must also know that high-quality, i.e. more expensive solar panels or inverters result in higher performance and, therefore, a higher return on investment.
The price of a solar system is determined by the materials purchased – panels, inverter, battery, support structure – also affects its quality. The most significant item is of course the material cost, followed by the price of installing and constructing the system, but there are smaller “mandatory expenses” that also add to the final price: such as the cost of fittings, cables, connectors, or the licensing procedure for the solar system with the electricity supplier.
Size matters.
However, before filling out any solar panel calculator, the most important question should be clarified in advance. How big a system do we need? If we choose a smaller one than necessary, the panels will not produce enough solar energy, so we will have to pay the excess consumption to the electricity supplier. However, if we size the solar panel system too large, we will have spent more money unnecessarily on an investment that is larger than necessary. We can calculate our annual consumption from our electricity bills, and we have to consider whether a system of this size will be sufficient. powerful solar panel system.
If our plans include buying an electric car that we would like to charge at home, or if we would like to modernize our heating towards electricity-based systems, or if we would like to develop our business in this direction, then we must also take this consumption into account, meaning we will need a higher-performance system and the planning and cost calculation must be carried out based on that.
Trusted brands also guarantee quality
THE solar panel The quality of the panels greatly influences their performance, so it is not unimportant which manufacturer the investing and construction companies order from. It is only worth choosing a brand that is reliable, promises a long warranty and is also listed on the international solar panel market. Prudence is important not only to choose the most suitable and budget-friendly solution for our personal needs, but also because quality elements contribute to higher performance, which in turn results in a faster return on investment.
The efficiency of the inverter also affects the overall performance of the system, so the saying is true here: we are not rich enough to buy cheap ones. Since the efficiency, lifespan and reliability of more expensive, “branded” products are much better than their “no-name” counterparts, it is worth thinking about the former, because this will pay for itself in the long run. When determining the size of the solar panel, it is therefore important to be aware of the performance and operation of the solar panel, because only with this knowledge can we calculate how large a solar panel system we need.
From panel to inverter
An average residential-sized system, which is around 3-5 kWp, can pay for itself in as little as 3-5 years, while the guaranteed lifespan of the panels is at least 25-30 years – in other words, if you like, solar energy produces an absolute return after the first few years. A solar system is also an excellent investment for companies, as it helps reduce their energy bills, or – if their annual consumption is no more than the energy produced by the system – they can forget about it. It also provides security in the event of a power outage, since if there is an energy storage device, the supply is continuous.
In addition, the production of electricity with solar panels leaves an order of magnitude smaller carbon footprint on our planet than its traditional, fossil-based counterparts. The maintenance cost of the panels is low, the inverter is the most important thing to pay attention to, but if it is placed in a protected and ventilated place, it will work reliably for a long time. The inverter converts the electricity produced by the panels into alternating current, which we can use to operate our household appliances, but we also feed this back into the grid – if regulations allow it –: the conversion efficiency of most models is 95-97 percent.
Flat, steep, slate... - or, let's assess the characteristics of the roof
The price of a solar panel system depends not only on the above, but also on the characteristics of the property where we want to install it. As for the roof, solar panels can be installed on practically any average roof, except for slate, unless it has an extremely bad angle of inclination or is in poor condition. In this case, it is worth thinking about replacing or modernizing the roof, such an investment is not wasted money, as it significantly increases the value of the given property, which is further increased by a modern solar panel system placed on a good supporting structure.
We can also install solar panels on a flat roof, but in this case it is usually necessary to carry out a static analysis due to the additional load. It is also important to have enough roof surface: this is mainly a problem with apartment buildings and terraced houses. The electrical network may also need to be expanded, but if we build the 3 phases, we will have enough capacity to charge an electric car.
What to look out for
It is a fact that in the long term, a solar panel investment is definitely a good option, as a well-designed system will pay for itself after a certain period of time, and if we also ensure the storage of the generated electricity by purchasing batteries, our energy dependence on electricity suppliers will decrease, and our own security in this area will increase. When considering such an investment, we must proceed with caution, as we will be ensuring our own energy supply for the long term.
It is worth looking for a partner company that already has sufficient experience in the domestic market, can navigate the legal mazes and fight bureaucratic obstacles for us, while flexibly adapting to our needs and dealing with us, the customers, in an individualized manner. Thorough preparation is important, which primarily begins with determining the size of the solar panel, as this has the most significant impact on the costs of the investment.
A good partner company also works with good suppliers, so it guarantees the quality and efficiency of the panels and inverters, and will also be there to help us when the system needs maintenance.
In summary: installing a solar system is a long-term, profitable investment that also protects our environment and increases our energy security, but we need to arm ourselves with thorough calculations and a good partner company to avoid potential pitfalls or disappointment in connection with a poorly designed and possibly shoddily constructed solar system.
