Connection box for solar panel
A box for connecting an output conductor from a solar panel with a feed cable has a base mountable on the solar panel and formed with a first hole for the panel-output conductor and a second hole for the feed cable, a removable cover fittable with the base in a closed position and forming in the closed position with the base a substantially closed compartment, and at least one component mounted on the cover in the compartment. The component is something that affects transmission of electricity from the solar panel into an electrical network connected to the feed cable or that affects the microclimate inside the connection box.
1. A box for connecting an output conductor from a solar panel with a feed cable, the box comprising:
a base mountable on the solar panel and formed with a first hole for the panel-output conductor and a second hole for the feed cable;
a removable cover fittable with the base in a closed position and forming in the closed position with the base a substantially closed compartment; and at least one component mounted on the cover and connectable with the output conductor and the feed cable when the cover is fitted to the base.
2. The connection box defined in claim 1 wherein the component affects transmission of electricity from the solar panel through the box.
3. The connection box defined in claim 1 wherein the component affects a microclimate in the compartment.
4. The connection box defined in claim 1 wherein the component is a connector that electrically connects the panel-output cable to the feed cable.
5. The connection box defined in claim 1 wherein the component is a conductive strip, a lead frame, or a switching or control element.
6. The connection box defined in claim 5 wherein the component is a diode.
7. The connection box defined in claim 1 wherein the component is a heat-dissipating element or a gas-exchange element.
8. The connection box defined in claim 7 wherein the heat-dissipating element is a heat-sink plate.
9. The connection box defined in claim 8 wherein the plate has a thermal bridges engaging a heat-transmitting circuit elements in the compartment.
10. The connection box defined in claim 9 wherein the thermal bridges are spring tongues.
11. The connection box defined in claim 9 wherein the thermal bridges are unitary with the heat-sink plate.
12. The connection box defined in claim 7 wherein the gas-exchange element is a sintered-metal plug fitted in an opening through a wall of the box.
