do not wire multiple panels in 

3. 

series. 

If you need to connect two 

or more solar panels together, this 

work must be done by a qualified 

electrician unless they are connected 

through a regulator.
This solar panel kit is not designed 

4. 

for tie-in to a grid.  Only a licensed 

electrician and a licensed building 

contractor can safely design and 

implement a grid tie-in system.  Any 

grid tie-in system must meet all 

applicable building and electrical 

codes, and must meet standards 

established by the area power 

company.  Improper grid tie-in can 

result in electrocution, fire, and other 

serious personal injury and property 

damage.  An incorrectly installed grid 

tie-in system can cause feedback 

voltage, resulting in electrocution of 

electrical utility workers.

do not stand on or otherwise apply 

5. 

pressure to panel.
handle solar panel with care, 

6. 

edges may be sharp.
do not focus light on panel.

7. 

Install components with enough 

8. 

space to allow proper cooling.
This product may occasionally 

9. 

produce more current and/or 

voltage than its rated output.  

Increase output ratings by 25% 

when determining component 

required voltage and amperage 

ratings.

  Refer to Section 690-8 of 

the National Electrical Code for an 

additional multiplying factor of 125 

percent (80 percent derating) which 

may apply.

Panel must be connected using 

10. 

UL listed outdoor rated wire of the 

correct thickness (gauge) for the 

amperage rating and length (see 

warning number 9 also).  Follow the

controller/regulator to regulate output 

and prevent damage.  Do not attach 

panel to battery or power grid without 

proper regulator, inverter, and/or 

charge controller.
Install and use according to 

12. 

applicable National Electrical Code 

(NEC) standards.
This panel is not rated for use as 

13. 

fire-resistant roofing.  If installing on 

a roof, install only over a fire resistant 

roof covering rated for the application.
Verify that installation surface has no 

14. 

hidden utility lines before drilling or 

driving screws.
Install only according to these 

15. 

instructions.  Improper installation 

can create hazards.
