Blutricity and EU are two completely separate power sources. You don't take power from a blutricity Battery Box and wire it into a BatBox. As Purplenate said, ensure that both of them have no blocks (including wires and cables) above them beside glass. For the "big solar panels", which are the EU producing ones, use a tin/copper/gold/glass-fibre cable to transfer power or place a Batbox directly next to it. For the "flat ones", which are the blutricity producing ones, use blue alloy wire or place the Battery Box directly next to it.

Also keep in mind that rain and storms can affect your solar panels' output as well.
