Start with the load profile
A solar design should begin with when the villa uses electricity. Annual consumption alone cannot show whether demand falls in the middle of the day, after sunset or mainly during a few busy summer months.
Bills provide a starting point. Pool schedules, air conditioning, electric water heating, cooking, vehicle charging and occupancy then explain the peaks behind the total. That distinction affects the array size, inverter and whether storage is likely to be useful.
Surveying the roof and electrical installation
The roof survey records usable areas, orientation, pitch, shading, access and the condition of the mounting surface. Jávea villas often have several roof sections rather than one uninterrupted plane, so a drawing based on satellite imagery is only an initial indication.
The electrical survey checks the supply, consumer unit, earthing, cable route and suitable positions for the inverter and any battery. A three-phase supply or an older electrical installation can change the design and should be identified before the quotation is fixed.
Choosing the array and inverter together
Panel layout and inverter selection are connected decisions. A clean roof may suit a conventional string inverter. Roofs with several orientations or recurring shade may justify Enphase microinverters and panel-level monitoring.
A SolaX hybrid inverter may suit a design that includes compatible battery storage or allows for it later. Battery compatibility, backup requirements, monitoring and possible expansion are easier to provide when they are specified at the beginning.
Full-time homes and holiday villas
A full-time home usually has a steadier base load and more evening consumption. A holiday villa can have long quiet periods followed by heavy demand from cooling, pool equipment and guests.
Sizing from the busiest August bill can leave a holiday property exporting surplus for much of the year. Sizing only from a quiet month can leave useful summer demand uncovered. The proposal should show which pattern it has been designed around.
Planning for air conditioning, pool heating and EV charging
New electrical loads can materially change the value of solar. If Kosner air conditioning, pool heating or an electric vehicle is planned, the expected usage and likely operating times should be included.
This does not always mean fitting the maximum possible number of panels immediately. It may mean choosing an inverter and electrical layout that allow the system to expand without replacing major components.
What a useful proposal should show
A proposal should make the reasoning visible. It should show the panel layout, expected production, inverter arrangement, storage assumptions and the main loads the design is intended to offset.
Savings estimates are only useful when the electricity price, self-consumption level and occupancy assumptions are stated. We explain those assumptions so different options can be compared on the same basis.
See how a system would work for your home
The assessment joins the roof survey and electricity profile into one design. You can see how the equipment fits together, where it would be installed and what changes if storage or future loads are included.
That gives you a system specification to consider rather than a panel count with the important decisions left until installation day.
Questions homeowners ask
Frequently asked questions
Can a solar system be designed from electricity bills alone?
Bills are useful, but they do not fully show when electricity is used. Occupancy, pool schedules, cooling, heating and other large loads need to be understood as well.
Does a three-phase supply affect the design?
It can. The inverter and connection arrangement must suit the property’s electrical supply and comply with the requirements that apply to the installation.
Should I allow for a future battery?
If storage is a realistic future plan, choosing compatible equipment and a suitable installation layout now can avoid unnecessary replacement work later.
Can the system be expanded later?
Sometimes. Expansion depends on roof space, inverter capacity, electrical limits and the compatibility of additional equipment. It is best treated as a design requirement from the start.
