Off-grid possible but costly and complex

Requires large batteries and backup systems

Grid-connected systems offer more reliability and savings

Hybrid setups provide flexibility and autonomy

Full independence suited for rural or remote areas

Yes, in most cases you’ll still receive an electricity bill — but it will be significantly lower. Your bill reflects the energy you draw from the grid, any fixed connection fees, and how much surplus energy you exported under net metering. Many households in Marbella reduce their energy bills by up to 70–90%, and with battery storage, reliance on the grid can drop even further.

Key points:

You still pay connection fees and any grid use

Solar reduces energy bills by up to 90%

Net metering can earn credits for exported energy

Batteries can reduce or eliminate evening usage costs

Some months may result in €0 or negative bills

In most standard grid-tied systems, your solar panels will automatically shut down during a power outage for safety reasons. This prevents any electricity from backfeeding into the grid and harming utility workers. However, if your system includes Solar battery storage with backup capability, you can continue powering key appliances during blackouts. These hybrid systems automatically switch to battery power, ensuring continued energy use even when the grid goes down.

Key points:

Grid-tied systems shut down during outages for safety

Battery backup allows continued electricity use

Backup can power lights, Wi-Fi, fridge, and more

Smart inverters are needed for seamless switchover

Hybrid setups add resilience and peace of mind

Solar batteries aren’t essential but offer major advantages. They store excess energy your panels generate during the day for use at night or during outages. In Spain, where net metering compensates for surplus energy, batteries are ideal for homeowners who want greater energy independence. Though an added investment, batteries can enhance self-consumption, protect against rising electricity prices, and provide backup power.

Key points:

Batteries allow night-time and backup energy use

Increase energy independence

Help avoid using grid electricity during peak rates

Add to installation cost: approx. €3,000–€6,000

Ideal in areas with frequent outages or high tariffs

Your roof’s suitability depends on sun exposure, pitch, orientation, and structure. South-facing roofs with little shade perform best in Marbella’s sunny climate. While angled tile roofs are common and compatible, installers also work with flat roofs using mounting racks. An assessment by a professional installer will confirm whether your roof can support the weight and layout of a solar system.

Key points:

South-facing roofs offer optimal performance

Minimal shade = higher energy production

Roof structure must support panel weight and racking

Flat roofs work with tilted mounts

On-site assessments are highly recommended

Flat roofs or limited space aren’t dealbreakers. Flat roofs can accommodate solar using angled mounts to maximise sun exposure. If your roof space is small, high-efficiency panels may help you generate enough power. Ground-mounted systems or even solar pergolas are also viable if roof space is unavailable. A tailored system design ensures that even small or non-traditional spaces can go solar.

Key points:

Flat roofs require angled brackets or ballast systems

High-efficiency panels work well in tight spaces

Ground-mounted or pergola systems are alternatives

Output may be slightly lower but still worthwhile

Professional layout design is key to efficiency
