It’s strange to think that a country capable of boasting more than 300 days of sun per year had, until just a few years ago, only 1,000 solar installations, compared to 1 million in Germany. This was largely due to Spain’s infamous ‘sun tax’, which previously levied unfair taxes on solar panel users, making it a cost-prohibitive option.

Thankfully, in 2018 all that changed. The ‘sun tax’ was abolished and the way paved for homeowners and businesses to install and use solar PV panels to power their homes or premises. Since then the number of solar panel installations in Spain has been on the rise and in the last year, as wholesale energy costs have soared, so too has demand for solar panels.

Green energy company, Mariposa Energía has been installing solar PV panels across Spain since 2019 and has seen the business go from strength-to-strength as more and more consumers realise the huge benefits solar panels have to offer.
Solar panels provide substantial long-term savings for those who choose to install and use them. In addition they also provide more flexibility. In June 2021 the government changed the way that electricity is charged for, introducing what is effectively peak and off-peak hours. Electricity is now at its cheapest through the night, between midnight and 6am and at weekends, which has forced consumers to change their energy usage habits. But with solar panels, this is not the case. There is the flexibility to use high-consuming appliances, such as the washing machine and dishwasher, during the day without it denting the bank balance.

Plus, of course, solar panels help to protect the future of our planet. Unlike traditional fossil fuels, solar energy does not produce the harmful emissions, which are one of the main contributing factors to climate change. By moving to solar panels, consumers can substantially reduce their carbon footprints, improve the quality of the air we breathe and help to preserve the planet for future generations to come.

A very straightforward process

Installing and using solar panels is actually very straightforward and at Mariposa Energía the team takes care of the whole process. It all starts with a survey of the property and a proposal, based on the property and the client’s typical energy consumption. The proposal is so detailed that it includes a 20-year forecast, illustrating the savings that can be made. While each installation is unique it takes on average just a few years to realise a return on investment.

All installations come with a 30-year fully comprehensive guarantee, giving consumers peace of mind that their investment will stand the test of time and full maintenance is provided, although solar panels require very little maintenance.
The Mariposa Energía team also handles all of the registration paperwork on behalf of the client and offers low-cost finance options.

Martin Tye, CEO of Mariposa Energía said: “Solar panels are a fantastic investment and, with the huge rise in wholesale energy costs that we have experienced, there has never been a better time to consider going solar. You will save money, you will realise a very rapid return on investment and, at the same time, you will help to save the future of our planet.”
