Commercial solar payback in Santa Cruz de Tenerife: 3.3 years
A self-consuming 100 kWp array on a commercial roof in Santa Cruz de Tenerife typically pays back in about 3.3 years. That figure uses Santa Cruz de Tenerife'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.
Santa Cruz de Tenerife is in Canary Islands, alongside Las Palmas de Gran Canaria, San Cristóbal de La Laguna and Telde. 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 Santa Cruz de Tenerife. 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 Santa Cruz de Tenerife cannot beat roughly 3.3 years on these inputs, it is probably not a priority lead.
Santa Cruz de Tenerife versus the rest of Spain
Relative to Spain as a whole, payback in Santa Cruz de Tenerife 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 Santa Cruz de Tenerife 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 Santa Cruz de Tenerife 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 Santa Cruz de Tenerife sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Santa Cruz de Tenerife?
About 3.3 years for a self-consuming 100 kWp rooftop in Santa Cruz de Tenerife. 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 Santa Cruz de Tenerife?
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 Santa Cruz de Tenerife better than nearby towns?
Payback is in the same band as Las Palmas de Gran Canaria, San Cristóbal de La Laguna and Telde because they share the Canary Islands irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Santa Cruz de Tenerife with a pre-computed saving so you can compare sites, not just towns.
