Residential
Residential Solar
Solar for villas, houses, townhouses and renovated properties on the Costa Blanca, sized around the roof you have and the way the household actually uses electricity.
Residential solar
Solar that fits the house, not the other way around.
Villas, detached homes, townhouses, renovated properties and new builds all present a different roof, a different consumer unit and a different daily rhythm.
The starting point is never a panel count. It is the surface that is genuinely usable, the electrical capacity already in the building, and the hours in which the household draws power.
01
Villas and detached homes
Usually the most roof area and the most freedom in layout, often with pool equipment or air conditioning shaping the daytime load.
02
Townhouses and terraces
Less roof, more shading from neighbouring buildings, and tighter constraints on where the inverter can reasonably go.
03
Renovations and new builds
The one moment when cable routes, roof reinforcement and consumer unit space can still be arranged around the system.
What we assess
The survey before the proposal.
01
Roof and orientation
Usable surface, pitch, compass orientation, roof covering and structure, plus shading from trees, chimneys, parapets and neighbouring buildings across the day and across the year.
02
Current energy use
Annual consumption tells you very little on its own. What matters is the daily shape: whether the house draws power at midday, in the evening, or seasonally around a pool or air conditioning.
03
The existing electrical setup
Supply capacity, the state and spare capacity of the consumer unit, earthing, and the practical route from the array to the inverter and on to the board.
04
What is planned next
An electric vehicle, a pool heat pump, an extension or a change of use all belong in the design now, even when they are years away.
Design decisions
The choices that actually change the outcome.
Every one of these is settled in writing before installation is scheduled.
System sizing
Sized against the consumption the household really has, not against the roof it happens to own. An oversized array that exports most of its output at midday rarely earns its extra cost.
Inverter choice
Matched to the array layout, to the number of orientations involved, and to whether a battery is fitted now or expected later. A hybrid inverter costs more up front and saves a replacement later.
Battery-ready design
Even when no battery is fitted, the position, cable route, protection and space in the board can be reserved. Retrofitting all of that afterwards is what makes late batteries expensive.
Battery storage
Sized on the energy the household uses after generation stops, on an ordinary day. Backup during a power cut is a separate function, and only some configurations support it.
EV charging integration
A charge point is a large, controllable load. Planned with the rest of the system, it can be told to draw when generation is available rather than competing with the house.
Monitoring
Set up at commissioning so generation, consumption and stored energy can be read from a phone, and so an unexpected change is visible early.
Typical project stages
What happens, and roughly when
Durations depend on the property, on access and on scheduling. The order does not change.
| Stage | What happens |
|---|---|
| Assessment | Site visit, roof and electrical survey, review of consumption data. |
| Design | Array layout, inverter and protection selection, battery and charging decisions. |
| Proposal | Scope, components, drawings and the boundaries of the work, in writing. |
| Installation planning | Access, scaffolding or roof safety, isolation windows and a date. |
| Installation | Mounting, array, cabling, inverter, protection and any battery or charger. |
| Commissioning | Testing, configuration, monitoring setup and a walkthrough of the system. |
| Handover | Drawings, datasheets, test records and monitoring access, handed over together. |
Before you commit
Questions worth asking any installer.
These are the questions that separate a designed system from a delivered pallet of equipment. Ask them of us as well.
The answer should refer to your consumption pattern and your usable roof area, not to a standard package. If the same size is proposed for every house on the street, it was not designed for yours.
Generation that is not consumed on site and not stored is exported. How that is handled depends on your supply contract and on the rules in force at the time, which is a question for your electricity supplier rather than your installer.
Usually, but how easily depends entirely on decisions made now: the inverter type, the space left in the consumer unit, and whether a cable route and mounting position were reserved. Ask for this to be stated in the design.
Roof penetrations are part of the installation, so responsibility for them should be written into the scope along with the mounting system used and how it suits your roof covering.
At minimum: the array layout, a single-line electrical diagram, datasheets for the installed components, commissioning and test records, and working access to the monitoring.
Next step
Start with the house, not with a quote.
Send us the property details and how the household uses electricity. We will tell you what is realistic on that roof.
