Why switch to solar energy now
Three honest takes on photovoltaic self-consumption: your power bill, supply independence and environmental footprint. What changes for you from the first month.
The question is no longer “is solar worth it?”. That was settled years ago when panel prices collapsed. The useful question is why do it now and not two years from now. Here are three answers, no marketing.
1. Your power bill isn’t set by the market alone anymore
In 2024 Spain produced over 20% of its electricity from photovoltaic alone, but the price you pay on your bill isn’t dropping at the same pace. Grid fees, taxes and retailer margins still push a kWh from the grid to €0.15–0.30, while the kWh you generate on your own rooftop runs around €0.05.
The gap isn’t “savings”: it’s margin you’re recovering. Every year you keep buying all your energy from the retailer, you leave that spread on the table.
2. Real independence from the grid
The blackouts across Europe in the last year reminded everyone of something engineers already knew: the Iberian grid is not infallible. A properly sized solar installation (with or without batteries) gives you:
- Operational continuity during micro-cuts and voltage dips.
- Partial insulation from market price spikes.
- Headroom to grow: if tomorrow you add an EV, a heat pump or more machinery, the infrastructure is already there.
3. The clearest ROI of any sustainable investment
A well-sized residential installation pays back in 5 to 8 years and produces for 25 years. That’s 17 to 20 years of free electricity after payback. Few business investments (and almost no household one) have such an honest profile.
And if you do it via leasing, you don’t even immobilise capital: you pay a monthly fee lower than your current bill and, at the end of the contract, the plant is yours.
Where to start
Three questions worth answering before asking for quotes:
- How much do I consume, and at what hours? (Solar produces during the day; if your consumption is nocturnal, you need batteries or grid feed-in.)
- How much roof do I have, and what orientation?
- Do I want to own the plant or treat it as an operating expense?
