Every day more and more people are wondering about it. Even more so in the past weeks, when power companies have started offering discounts to their clients due to the crisis originated from the Covid 19 outbreak. However in our country it doesn’t seem to be the case. But is it really worth it? The answer is “it depends”.

If you expect a full return on investment in a 1 or 2 years period, it isn’t your best choice. Return on investment starts after six years, depending on consumption. However, if you’re after a long-term return on investment the answer is YES, categorically.


A solar panel system (instant self-supply, no batteries) in a single family home can provide up to 50% of the yearly consumption, although percentage can vary depending on consumption patterns. Let’s take into account that when are provided with a solar energy plant our energy consumption increases

It is worth mentioning that leading brands offer a return on investment warranty. For instance, at TCsolar we install panels with a 12-year structural warranty. If we are able to adapt our consumption pattern, we can shorten the time to get a return on investment.

Some advantages other than the economic savings are for example the increase in the value of the house, or the better thermal insulation in the area where the panels are installed, caused by the solar energy they receive during the summer months.

All in all, if you are sure you are after a medium-long term return on the investment, we encourage you to request a feasibility study for your home.
