Frequently Asked Questions

The cost varies depending on the size of your system, whether you include battery storage, and the complexity of the installation. Reach out to us to request a free quote, tailored to your energy needs and made for your home.

You can potentially save 50% to 80% or more on your electricity bill, depending on your usage habits and whether you have battery storage. During daylight hours, your home can run mostly or entirely on solar energy. If you don’t use a lot of energy during the day, storing energy in a battery or feeding it back into the grid for credit can help maximize your savings. Over a year, this can translate into hundreds or even thousands of euros saved, particularly for large homes or villas with air conditioning and pool pumps.

The average return on investment is around 5 to 9 years. This depends on how much energy you consume, how much of that you can offset with solar, and whether you benefit from subsidies or incentives. Systems with battery storage may take slightly longer to pay off but offer higher independence from the grid. With rising electricity prices in Spain, many homeowners are seeing faster ROI than expected.

You must register your system with the electricity grid (through your energy company) and inform the local town hall (Ayuntamiento). Some municipalities may request an additional installation permit, especially if your system includes battery storage or alters the building structure. We offer full assistance to manage all paperwork for you, which makes the process smoother and legally compliant.

Yes, Spain supports a system called “compensación simplificada”, which lets you feed surplus energy back into the grid in exchange for a credit on your electricity bill. While you don’t get paid in cash, the credit reduces your bill — especially useful during times when you draw power from the grid (like at night or on cloudy days). Your energy company must support this system, and the paperwork must be correctly submitted (so your system is legalized and registered). We offer full assistance for your installation and choosing the best energy provider for your needs.

Batteries are not required, but they can be very beneficial. A solar battery allows you to store excess solar energy during the day and use it at night or during peak times when electricity is more expensive. This can push your self-consumption rate from 30–40% up to 70–90%. They are particularly useful in areas with frequent power outages or where grid reliability is an issue.

Yes, there are several grants and subsidies available at both national and regional levels. On the Costa Blanca, the Valencian Community often offers subsidies that cover up to 40–50% of installation costs, especially for residential users and first-time solar adopters. You may also benefit from property tax (IBI) reductions and income tax deductions. These programs change periodically, so bear in mind that we usually apply for available aid but don't use it in our calculations to lower the initial selling price (which is very common sales technique).

In most cases, yes — solar panels can increase your home’s value, especially in a region like the Costa Blanca where sunshine is abundant and electricity costs are high. Energy-efficient homes are becoming more attractive to both local and international buyers. If you’re planning to rent or sell your property in the future, having a solar system installed is a strong selling point. It’s also viewed positively in energy certifications, which are often required for property sales in Spain and will become mandatory in the next years.

Yes, absolutely — and it’s one of the smartest ways to use excess solar energy. You can connect an electric vehicle (EV) charger directly to your solar panel system, allowing you to charge your car using free solar power during the day. Smart chargers can be programmed to prioritize solar usage, pause charging at night, and even sync with weather forecasts. If you have battery storage, you can also charge your car at night using energy stored from earlier in the day. It’s an excellent way to lower your overall transport and electricity costs.

Yes, and it’s a very effective combo. Heat pumps are highly energy-efficient systems that use electricity to heat and cool your home, often replacing traditional boilers or AC units. When paired with solar panels, the electricity needed to run the heat pump can come directly from the sun, significantly reducing your heating and cooling costs. On the Costa Blanca, where winters are mild and summers are hot, a heat pump can cover most of your climate control needs — and solar helps cut down the operating costs dramatically.

Most likely, yes. If you’re planning to run an EV charger or heat pump — or both — from solar, you’ll need to increase your system size to cover the added consumption. A typical EV might need an extra 2–4 kW of solar capacity depending on how much you drive. A heat pump may need another 1–3 kW depending on home size and insulation. During our free consult, we analyze your usage patterns (current and future) and design a system that balances solar production, battery storage (if included), and self-consumption goals.

That’s correct if you haven’t installed a backup module (also known as EPS or emergency power supply). Without this module, your system automatically shuts down during a power outage – even if you have a battery. With a backup module, your system can continue to operate during a power outage and supply power to essential devices.​
