NOVELTY - The box (10) for the circuit board of a solar module (4) contains contacts (12) with line connectors (14) and contact components (18). The cables (8) have conductors (22) contacted by the line connectors. A surrounding seal keeps moisture out of the cable ends. The casing arranged on the board, is connected to a seal surrounding the contact regions and keeping moisture out. The casing has a holder (34) with two openings. It contains the contact components (18) in connection with the circuit board. Components (42) fix the casing to the connections. A cover provides moisture-tight closure of the holder.    USE - A connection box for the circuit board of solar module. The box is adhered to the circuit board used to make a solar panel. It is used to connect the solar panel to a power consumer via the contacts (12) (all claimed).    ADVANTAGE - In this design, the contacts are reliably protected against moisture ingress. Assembly is simple and inexpensive. The parts count is small. The separate seals or use of injected sealant, ensure reliable sealing. The cable is protected at entry points by a sleeve of extruded sealant material. The assembly is encapsulated and consolidated when liquid sealant is injected and sets. Limits to the rate of moisture ingress and electrical insulation are discussed in relation to European standards. Suitable polymers are proposed. A built-in diode prevents damage to the solar cell or group of solar cells and maintains current delivery, in the event that isolated sections of the solar panel become damaged or shaded.    DETAILED DESCRIPTION - The seal is flexible, whilst the casing is essentially rigid. The two contacts (12) each have a short-circuit region (16) and/or at least one bypass diode. These are at least locally enclosed by the seal. The seal is coated as a fluid onto the cable, line connection, short circuiting region and bypass diode. On cooling and/or hardening, it forms an intimate mechanical connection with them. The seal is partially melted-into the insulating sheaths of the cables. The molten seal projects out of the casing (30), of forming a protective sleeve. This prevents cable-kinking. The casing itself, is coated-on in the fluid state, making an intimate bond with the components, through cooling and/or hardening. The casing is single-piece. It is at least partially melted-into the seal. The casing material shrinks more than the seal. The fixing component (42) and cover are single-piece. The cover has a seal and locking component. The fixing component is plastic or metal. INDEPENDENT CLAIMS are included for the following:    (A) a method of making a connection box;    (B) and a method of making a solar panel .
