The list covers Almería, Aguadulce, Viator and Huércal de Almería, among other towns. Within 20 km of Almería are Valener, compañía energética meridional, Electricity assemblies Moya and Proconsult. For work that needs return visits, a firm within an hour’s drive is usually worth a slightly higher quote.
Energia Grupo MSC, Imelect Energía Solar and Ayram Energías lead on Google among firms with at least 20 reviews. The average rating across the list is 4.7 (firms with at least five reviews). A handful of five-star reviews is a start, but ask for a job you can go and see.
Ask each installer to size the system from your actual use, appliance by appliance, rather than from the roof area. For an off-grid house the battery and the inverter matter as much as the panels, so get the battery chemistry, capacity and warranty in writing.
Questions to ask before you sign
- How many off-grid (stand-alone) systems have you fitted?
- Can you size the system from my appliance list?
- What battery chemistry, usable capacity and warranty are you quoting?
- Which inverter brand, and do you service it yourselves?
- What does the price include: fitting, cabling, certificates?
