By converting solar energy into electricity using solar energy, it is possible to realize self-consumption with less impact on the environment, and by reducing electricity costs, it is possible to save short-term and long-term. Specification. .. But how much energy can a solar panel generate?
Amount of energy we consume Determine the number of solar panels we will need if we choose to install solar panels in our home. Therefore, it is important to know not only the amount of energy we consume, but also the amount of energy produced by solar panels. In this way, you can optimize the number of PV panels to save as much electricity as possible and have less impact on the environment.
Electricity generated by domestic panels
How many kWh a solar panel produces is XNUMX, a common question that arises when we think about self-consumption. This also determines the cost and space required for installation. The power is the watts (W) produced by solar panels and depends on the type of panel, just as computers have different capacities depending on the model, because they have different capabilities.
The power is shown on the technical sheet of each panel in question, but the range of average power solar panels is 250W and 300W energy. You will also often find panels in homes with high power, such as 500 W, and even low power, such as 150 W.
Starting with a 300 W solar panel, this means that every XNUMX hours of sunlight will get that power. Based on a sunny day in a warm area, suppose you want to calculate:
- 300 Wx 5 days 1500 hours of sunshine = 1.5 W or XNUMX days XNUMXkWh.
Using these data, the annual sunshine hours , and the kWh that can be generated by the installation. On average annually, supplementing the hours of low winter sunshine and high summer sunshine results in a five-day average of about XNUMX hours of sunshine.
- 365kWh per 1.5 days x 547 days per year = XNUMXkWh per year for 300W solar panels.
If the selected solar panel has more or less power, you can simply change the formula to find out how much energy is produced.
Importance of daylight hours
This calculation is approximate Living in a southern region such as Malaga or Seville is not the same as living in a northern city such as Bilbao or Santander, so it is the amount of energy that a solar panel can produce. When looking at the number of solar panel wats and looking at 200W or 300W, keep in mind that the manufacturer refers to the power generated by the solar panel. Under optimal conditions , this is clearly not given every day of the year.
In summer, Bilbao and Malaga have the same hours of sunshine, but the actual hours of sunshine are very different. Sun generation rate Because it is more powerful in warm regions, it is more likely that solar panels will approach optimal power more often. The good news is that constant progress will allow solar panels to extract energy even on cloudy days.
In summary, when it comes to knowing how much power a solar panel actually produces, we should take into account one aspect of XNUMX : power, daylight hours, and the rate of solar generation in the place of residence. ..
