It means generating your own electricity with solar panels and using it directly at home or in your business. You’ll reduce your reliance on the grid and cut down your energy bills.

They capture sunlight and convert it into electricity using photovoltaic cells. That energy can be used immediately, stored in batteries, or fed back into the grid.

It depends on your energy use, roof space, and orientation. At Watts Renovable, we carry out a tailored assessment to design the most efficient system for you.

No specific taxes apply. In fact, many local councils offer discounts on property tax (IBI) and construction tax (ICIO), and there are income tax deductions available too.

You can store it in batteries or benefit from a feed-in scheme that lets you offset surplus energy against your electricity bill.

Not necessarily. In many cases, your existing meter can be adapted.

Without batteries, your system will shut down for safety reasons. With batteries or hybrid systems, you’ll still have power during outages.

Savings can reach up to 100%, depending on your usage, battery setup, and feed-in compensation. Public grants also help you recover your investment faster.

Yes, but it requires a formal contract with your energy provider. Most people opt for the simpler feed-in compensation model.

Yes, but it’ll be much lower. You’ll still pay the fixed part of your contract and any extra consumption not covered by your panels.

We install European-made solar panels with 20–25 years product warranty. Our inverters come with a minimum 12-year warranty — 7 years more than most brands — at no extra cost.

Solar systems require minimal upkeep, but regular checks are recommended. We offer annual maintenance plans to keep your system running at peak performance.

Yes! In Catalonia, there are several public incentives — ICAEN grants, Next Generation EU funds, local tax discounts, and income tax deductions. We take care of the entire process: identifying available support, preparing technical documents, and handling the paperwork.

Yes! Shared self-consumption is a legal option that allows energy to be distributed across multiple users. Perfect for residential blocks, nearby businesses, or families sharing a space. We help you legalise it and set up fair distribution.

Yes, absolutely. Current regulations actively support solar installations with simplified procedures and technical guidance.
