Re: How does one check amperage on Solar panels NOT connected to batteries? On most general purpose (cheap) DVM's you don't move the black ground connection. You move the red probe lead from the Volt… (View Post)

Primary new items in PV tech is reducing reflection from cell surface allowing more energy absorption and use of N doped subtrates which have a little better efficiency. There are two reasons for mak… (View Post)

A common issue is generator rpm speed governor is off. Assuming it is a regular generator (not inverter-gen) the accuracy of 60 Hz depends on generator engine speed. Most cheap digital multimeters th… (View Post)

You probably got used cells taken out of service when their capacity drop to 80%. You need to measure their impedance. Used cells have thicker growth of SEI layer which increases cell impedance and c… (View Post)
