General Information

The installation of solar modules (panels) requires a great degree of skill and should (if DC voltage exceeds 100V:) only be performed by a qualified licensed professional.


1. Avoid electrical hazards when installing, wiring, operating and maintaining the module.

2. A photovoltaic module generates DC electricity when exposed to sunlight or other light sources.

3. When installing or working with module wiring, cover module face completely with opaque material to halt production of electricity.

4. It is recommended that the module remains packed in the box until time of installation.

5. Do not touch terminals while module is exposed to light or during installation. Provide suitable guards to prevent contact with 30VDC or greater. As an added precaution, use properly insulated tools only.

6. Do not drop module or allow objects to fall on the module.

7. Do not stand or step on module.

8. Since sparks may be produced, do not install module where flammable gases or vapors are present.

9. Never leave a module unsupported or unsecured. If a module should fall, the glass can break. A module with broken glass cannot be repaired and must not be used.

10. Work only under dry conditions, with dry module and tools.

11.Module installation and operation should be performed by qualified personnel only. Children should not be allowed near the solar electric installation.

12. If not otherwise specified, it is recommended that requirements of the latest local, national or regional electric codes be followed.

13. Use module for its intended function only.

14. Do not artificially concentrate sunlight on the module.

15. The word "module" as used in this Guide refers to one or more photovoltaic modules (panels).


1. All instructions should be read and understood before attempting to install, wire, operate and maintain the photovoltaic module. Contact with electrically active parts of the module such as terminals can result in burns, sparks, and lethal shock whether the module is connected or disconnected.

2. Photovoltaic modules produce electricity when sunlight or other sources illuminate the front face. The voltage from a single module is not considered a shock hazard. When modules are connected in series, voltages are additive. When modules are connected in parallel, current is additive. Consequently, a multi-module system can produce high voltages and current which constitute an increased hazard.
