Commercial solar payback in Arona: 3.3 years
A self-consuming 100 kWp array on a commercial roof in Arona typically pays back in about 3.3 years. That figure uses Arona's specific yield of 1,782 kWh per kWp per year and a commercial tariff near €0.22/kWh, with 70% of generation used on site.
At that yield the array produces about 178,200 kWh a year and saves roughly €27,443 annually against an installed cost near €90,000. Over 25 years the net saving is around €596,075, while avoiding about 62.4 tonnes of CO₂ each year.
Arona is in Canary Islands, alongside Las Palmas de Gran Canaria, Santa Cruz de Tenerife and San Cristóbal de La Laguna. Those towns share the same irradiance zone, so payback is similar — the difference is which warehouses and factories still have empty roof. SolarScout lists them with a pre-computed business case rather than a generic "solar is cheap" pitch.

Start with 100 kWp × 1,782 kWh/kWp = 178,200 kWh of annual production on a representative warehouse or factory roof in Arona. Apply 70% self-consumption against €0.22 per kWh and you get about €27,443 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 3.3 years.
This is a worked example, not a quote. Real payback moves with self-consumption, shading, export tariff and installed cost. It is still the right first filter: if a roof in Arona cannot beat roughly 3.3 years on these inputs, it is probably not a priority lead.
Arona versus the rest of Spain
Relative to Spain as a whole, payback in Arona is about 0.5 years faster than the Spain average of 3.8 years. Spain has Europe’s strongest solar resource. High specific yields on industrial estates and logistics parks make commercial rooftop solar one of the best-returning energy investments on the continent.
That is why outreach in Arona should open with the local number — 3.3 years and €27,443 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Arona roof
Yield is already baked into the 1,782 kWh/kWp zone for Canary Islands. The bigger swings are usable roof area, daytime load (factories and cold stores self-consume more than empty warehouses) and whether the site pays the full €0.22/kWh commercial rate.
SolarScout estimates roof footprint from satellite and map data and, where Google Solar coverage exists, modelled annual output — so you can rank Arona sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Arona?
About 3.3 years for a self-consuming 100 kWp rooftop in Arona. That uses 1,782 kWh/kWp of local yield and a tariff near €0.22/kWh, saving around €27,443 a year.
How much electricity does 100 kWp produce in Arona?
Around 178,200 kWh a year. Multiply the 1,782 kWh/kWp specific yield for Canary Islands by 100 kWp; shading and orientation can move that figure, which is why SolarScout models each roof rather than stopping at the city average.
Is payback in Arona better than nearby towns?
Payback is in the same band as Las Palmas de Gran Canaria, Santa Cruz de Tenerife and San Cristóbal de La Laguna because they share the Canary Islands irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Arona with a pre-computed saving so you can compare sites, not just towns.
