Neorenovables, Grupo Mostazo and Smartpv lead on Google among firms with at least 20 reviews. The average rating across the list is 4.8 (firms with at least five reviews). Read the low-star reviews as well as the high ones: how a firm answers a complaint tells you a lot.
Off-grid work is different from grid-tied rooftop solar. Ask how many stand-alone systems the firm has fitted, which inverter brands it services itself, and what happens if the battery fails in August.
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?
