Pros and cons of solar energy

On the other hand, the initial cost can be high and the efficiency of the system can be affected by shading or inappropriate location.

Investing in photovoltaic solar energy: what is the monthly financial return?

For example, by investing 100 thousand reais in photovoltaic energy, this investment amount makes it possible to build a 30 kWp (kilowatt-peak) plant, which is equivalent to generate enough energy to cover monthly consumption of approximately four thousand kWh (kilowatt-hour).

An investment of this magnitude can meet the energy demands of small commercial establishments, such as bakeries, grocery stores and butchers. With an average monthly consumption of four thousand kWh, The cost of this energy varies between 6 thousand and 8 thousand reais per month.

For those with high consumption, the average monthly return when renting equipment is 6 thousand to 8 thousand reais. For those who intend to rent the plant, the average monthly return is around 6 thousand reais.
It is important to highlight that these values ​​are based on a 30 kWp plant, which can be assembled with a investment of 100 thousand reais.
