How it works

Step 1: Contact us to request packs of 50 stick on cell templates
Step 2: Stick paper templates on a single curve surface (Difference between single and complex curves)
Step 3: Place a big black mark on the cell where the cable gland will be underneath.
Step 4: Choose either stick on or glue one
Step 5: Send photograph and info to
Step 6: We send you a quotation
Step 7: Payment
Step 8: 2 weeks later you receive your panels. 

We have installers currently in Ontario and BC. Once per year in March we will be installing panels in St Martin.


Solar System Design

Designing solar panels requires careful consideration of their specific application. Shade has a significant impact on solar panel performance, making the layout of cells, the number of bypass diodes, and their orientation crucial in areas with variable shade.

Solar cells are typically connected in series to efficiently transmit energy, with each cell providing 0.67 volts. However, when a shaded cell creates resistance in the series, it can activate the bypass diode, which is essential for panel safety. The high current passing through a high-resistance cell can generate excessive heat.

To illustrate this, consider the analogy of old-school Christmas lights. If one bulb goes out, the entire string of lights stops working due to the series connection. Similarly, solar cells still require a series connection because they lack the capability for parallel connections like LED Christmas lights, which operate on low current.

In summary, the design of solar panels must account for shade effects, series connections, and the importance of bypass diodes to ensure optimal performance and safety.

Standard Panels

Back Mounted Junction Boxes


  • 41.5” x 21.5”
  • 4×8 cells
  • 32 cells
  • 2 bypass diodes


  • 41.5” x 26.5”
  • 5×8 cells
  • 40 cells
  • 3 bypass diodes


  • 41.5” x 31.5”
  • 6×8 cells
  • 48 cells
  • 3 bypass diodes

Contact us for custom panel prices. Typical panels have bypass diodes every 15 to 20 cells. Increased number of bypass diodes increases the effectiveness of the panel but increases the cost.

Custom panels can be any shape given a 5” x 5” cell formation.
