I installed them on 12 rechargeable motorized blinds. The shutters are on the south side of my house where there is a lot of sun most of the day. I checked the voltage before installing and they seemed to produce a decent output even in low light. Brackets are well made. The power cord that connects to the battery is long, I shortened mine. Customer support was excellent. There was a manufacturing defect on one of the mounts - the seller responded quickly and sent a new mount at his own expense. Can't ask for more. It will be interesting to see how they behave over time.
