What to Buy — and How Not to Get Cheated

Buy on verification, not on brand loyalty. For panels that means a serial checked against the manufacturer’s own portal and a barcode visible inside the glass. For inverters it means asking who actually builds the unit and where the service centre is. For batteries it means cycles, not years. These guides give you the check, brand by brand.
