Photovoltaic solar panels are technological innovations made to harness solar energy for use in daily life. The cost of installing photovoltaic solar panels is currently quite affordable.
Due to the energy savings they can offer and the ensuing environmental preservation as a result of the minimal emission of hazardous agents, installing a solar energy system at home becomes a financially advantageous choice.
An average cost of between 600 and 800 euros per square meter should be expected when installing photovoltaic solar panels. The larger the facility, the lower this quantity becomes.
Your home’s consumption requirements will determine how many solar panels you need, and this number is often related to your home’s size, roof space, and physical installation capabilities.
Costs of 5 kW solar panels for personal use
The most popular solar energy system in houses is typically 5kW Solar Panels for Self-Consumption.
The power and size of a solar panel affect its average price. For instance, a 100w plate can cost between 80 and 100 euros per unit, which translates to a 0.8 or 1 euro cost per watt.
Given that the average solar panel size is 1.65 square meters, 15 to 19 solar panels are required for an installation between 25 and 35 square meters. Additionally, the total cost of the plates could range between 4,300 and 5,700 euros if high-quality 300w power plates are employed.
Photovoltaic plate kits range in price from 600 euros to 16,000 euros, depending on the brand, quality, power, and size of the plate as well as the available area.
How many solar panels will I need for a 100-square-meter house?
Later on, we’ll provide you with the information you need to know about their costs. The number of photovoltaic solar panels required for a house will depend on the wattage of each panel and the quantity of electricity used monthly in the household.
You can use the following information to calculate how many solar panels you need.
You can estimate the required amount of energy by counting the number of watts you consume each day. how many hours a day there are of sunlight where you live. the surface of the house’s roof.
For a 100 m2 house with an average energy usage of 1200 Kw and 250 W power panels, 40 self-consumption panels are required to supply the full house’s energy needs. On the other hand, 20 plates would be needed to serve 50% of the guests.
Always keep in mind that the number of solar panels you need will depend on your home’s energy requirements and the features of the panel you choose.
The price of installing solar panels
The cost of the installation will vary depending on the type of photovoltaic panel system that is placed in your home. The quantity will also significantly impact the installation’s overall cost, just like the brand and quality of the panels.
Some installation budgets for solar panels assume a cost of 10% of the entire solar kit cost, which must be taken into account in the installation’s overall cost estimate.
Since this will have a big impact on the final expenses, it is crucial to calculate the number of photovoltaic panels that will be employed correctly.
Prices of a Plate Kit or Solar Panel Kit for Personal Use
Photovoltaic panels are only one component of solar self-consumption systems; you also need to include the battery, the inverter, and other components that come with the solar panel kit. We’ll then discuss how much different photovoltaic solar panel kits cost.
Set of Solar Panels (Isolated)
This kind of system costs 6,205 euros, covers 3000w of energy, and is linked to a battery rather than the home’s electrical supply. Contains:
- 6 plates of 260w, 12 batteries, 5topzs 442 575ah C100, and a Victron Multiplus Pure Wave 3000w Inverter Charger.
- Floor structure for the Victron bmv 700 battery monitor
- Spanish wiring and installation instructions
- Photovoltaic Panels: Kit of 2 Solar Panels
- Solar Kit for Self-Consumption: 1 YC500 microinverter, 5 Aluminum Support Structure for the Plates, and 2 260W Plates
- This package costs approximately 670 euros.
As has been mentioned, a number of variables you must assess in light of your home’s consumption requirements will affect the overall cost of the solar panels and their installation.
