Solfit 370Wp Solar Panel Instruction Manual

Solfit 370Wp Solar Panel

Product Information

The Solfit 370Wp is a solar panel installation system designed for residential and commercial use. It consists of various components that are necessary for the installation process.

• SolFit Component parts: This refers to the different parts included in the installation kit.
• Mounting profile: A profile used for mounting the solar panels.
• Flashing: Flashing is used to provide weatherproofing and support for the solar panels.
• MC4 connectors: These connectors are used to connect the solar panels together.

Product Usage Instructions

1. Spacing between battens: The recommended spacing between the mounting battens is 1055mm center to center or 1005mm internal gap.
2. Measuring gap between battens: Use measuring sticks to ensure the mounting battens are spaced at 1.05m intervals. The length of the sticks should be 1005mm. Make sure the bottom batten is straight and level as all other measurements depend on it. A string line can be used for alignment.
3. Mounting the panels: Fix each panel with 6 screws per panel. Avoid letting the panel drop or slip down as it may affect alignment. Use panel shims to prevent lead from getting loose behind the panel. Secure the panels to the existing roof batten using 50mm screws.
4. Flashing installation: Install flashing using screws and neoprene washers. Use flashing joiners and stick joiners to connect the flashing. Make sure the flashing is tight and level.
5. Edge and bottom flashing: Allow for approximately 200mm of edge, turned up to prevent wind-blown rain. Secure the bottom flashing with flashing clips and 25mm screws.
6. Top row of panels: Fit the top row of panels tightly and square. Pay attention to wrinkling EPDM tape that may prevent them from being pushed tight.
7. MC4 connectors: Ensure the MC4 connectors “click” when connected. Improper connection can pose a fire hazard.
8. Completing the installation: Slide the bottom flashing joiner into position and push the bottom flashing together. If using slates, remove the bottom flashing to fix the slates and refit it afterwards.
9. Corner detail: When slating or tiling, the bottom course fits under the bottom flashing and flexible corner. Side slates/tiles fit over side flashings and flexible corner flashing.
10. Fitting Flexible bottom flashing: Use lead or lead substitute for the bottom edge of the panel. Use capping and internal capping strip joiners and end caps for a secure fit.
11. Fitting Internal LHS & RHS Flashing & couplers: Follow the provided instructions to fit the internal LHS and RHS flashings and couplers.

Installation

1. Measure size of array

   • X (width) = 1.8m x nom of panels
   • Y = (height) 1.04m x number of panels
   • Side flashing = 150 mm
   • Top flashing = 300mm
   • Bottom flashing = 150mm
     Allow space for 1 x tile or slate at bottom of array or 150mm if using metal bottom flashing. If using lead or lead substitute the array can go to gutter.

2. Fit mounting battens

   • Use only 25mm x 50mm battens

   • Fit double mounting battens at 1055mm metre spacing’s. centre to centre or 1005 m gap between batons
   • Secure lower battens with 50mm screws on every rafter

3. 50mm gap between existing & mounting batten

   • 50mm gap left between lower existing tiling batten and the lowest panel mounting batten to allow space for the tile nib, No gap required for slate.
   • TIP; Use a 25mm x 50mm batten as a spacer
   • No gap required for slates

4. Measuring gap between battens

   • To space mounting battens at 1.05m spacing’s, measuring sticks can be very useful, be sure to cut them square and exact for 50mm batten. Length = 1005mm
   • Ensure bottom batten is straight and level as this is where all other measurements come from. A string line can be used.
