The Value of Solar Gardens: Maximising their Energy Potential

In the ongoing search for sustainable and renewable energy sources, solar farms have
emerged as a promising solution in the global energy landscape.

These gardens, composed of a series of solar panels arranged on land specifically designed to
capture sunlight, play a crucial role in the transition to a cleaner and more sustainable
economy.

In this blog, we will explore the importance of solar gardens, the best season to install them,
the seasonal performance of solar panels and the need to keep them clean to ensure their
long-term effectiveness.

Importance of Solar Panel Gardens:

At a time when dependence on fossil fuels is raising environmental and economic concerns,
solar panel gardens represent a viable and environmentally friendly alternative.

These installations harness an inexhaustible and free source of energy: sunlight.

By converting solar energy into electricity, solar farms reduce the demand for fossil fuels,
reduce greenhouse gas emissions and contribute to climate change mitigation.
In addition to their positive environmental impact, solar gardens also offer significant
economic benefits.

Solar energy is a renewable and abundant source of energy, which makes it more predictable
in terms of long-term costs compared to fossil fuels, whose prices can fluctuate considerably.
In addition, solar farms can generate additional income through the sale of surplus energy to
local electricity grids.

The Best Season to Install Solar Gardens:

Geographical location and season play a crucial role in the efficiency and performance of solar
panel gardens.

While it is possible to install them at any time of the year, choosing the optimal season can
maximise their energy potential.

Ideally, spring and summer are considered the best seasons to install solar gardens.

The attached graph shows the monthly solar radiation in the community of Madrid and shows
that the months with the highest radiation are those in the spring-summer season.

Therefore, the choice of installing solar panels during the spring emerges as a strategic option.

During spring and summer, the days are longer and there is a higher incidence of sunlight,
which results in higher energy production.

In addition, warmer temperatures improve the efficiency of solar panels by increasing
electrical conductivity.

Seasonal Performance of Solar Panels:

While spring and summer offer optimal conditions for solar power generation, solar panels can
effectively produce electricity year-round, even in winter.

Although days are shorter and sunlight intensity may be lower in winter, technological
advances in solar panel manufacturing have improved their ability to capture diffuse sunlight
and generate electricity efficiently in less intense light conditions.

It is important to note that the performance of solar panels can vary depending on geographic
location, the tilt of the panels and the amount of shade they receive.

Proper orientation and regular cleaning of the panels are critical to ensure optimal
performance throughout the year.

The Need to Clean Solar Panels:

Regular cleaning of solar panels is essential to maintain their efficiency and prolong their
lifespan.

Over time, panels can accumulate dust, dirt, leaves or other debris that block sunlight and
reduce their ability to generate electricity.

Studies have shown that dirt accumulation can decrease the performance of solar panels by up
to 20%.

It is therefore advisable to clean solar panels several times a year, more frequently if they are
located in areas prone to pollution or dirt accumulation.

The cleaning of solar farms is a complex process, due to the large extension of panels that
need to be cleaned, in most cases several hectares, as for example is the case of the solar farm
Don Rodrigo located in Seville, is one of the largest in Europe since it has an area of 300
hectares, which is why in Cepillos Sacema we have developed our solar panel cleaning arm,
attachable to tractor to facilitate this arduous task.

It is important to avoid the use of aggressive chemicals or abrasive tools that may damage the
surface of the panels, unless the manufacturer of the panels indicates otherwise, or provides
some exceptions of chemicals suitable for their panels.

Conclusion:

In conclusion, solar panel farms play a key role in the transition to a more sustainable and
cleaner energy future.

Choosing the optimal season for their installation, along with regular cleaning of the solar
panels, are key factors in ensuring their long-term efficiency and performance.

By harnessing the power of the sun, we can move towards a greener, more habitable world for
future generations
