It holds modules in portrait, displaying a three-module tall design on one side. While the standard L-shape features a single cantilever, some variations have offset cantilevers. Because of the consistent sizes of the foundations and columns, this layout is typically more expensive.

2. T-Structures:

The T-shaped structure features cantilevers on both sides of the center column. This design can support three panels on each side, south, and north, all of which are supported by column beams. The T-shape, oriented North-South, is ideal for modules tilted southwards, especially in the Northern Hemisphere. This T-shape is popular not only because of its mono-slope form facing south but also because of its cost-effectiveness.

3. Y-Structures:

The Y-shaped configuration focuses on columns that run north to south, with modules facing east-west. Six panels become prominent in this setting, evenly distributed on each side of the columns. The water runoff pattern is one distinguishing feature; water converges and drains towards the center column. This design is distinguished by a single-post, single-column configuration. In this case, the panels are facing each other.

4. P-Structures:

The P-shaped is a notable design within the different types of solar carport. It’s commonly found in settings such as educational institutions or corporate offices where walkway coverage is required. This design allows additional modules – typically eight panels split across two beams of four panels each. This design is ideal for parking areas that need extra panels or have connecting pathways, offering greater structural capacity for specific parking needs.

5. W-Structures:

Among the different designs of solar carport, the W-shape structure features a unique design that has been carefully planned and tested to endure the most severe weather conditions, ensuring both safety and robustness. The efficient rainproof capability of its design is not only practical but also inexpensive. Moreover, the design provides for better waterproofing throughout, which not only serves as a water guide but also improves the overall aesthetic appeal.

Nevertheless, in the solar carport design, the dimensions and placement of the carport are critical. If your business relies on the parking of large delivery trucks, it’s advisable to maintain a minimum ground clearance of 14 feet.

Step 2: Design, Sizing, and Budgeting

1. Consider the size of your carport, taking into account the number of vehicles and the dimensions of your property.

2. When it comes to types of solar carports for DIY processes, there are two major materials to consider: timber and steel frameworks:

  • Steel-framed carports have more structural strength, which implies that steel frames are your best option if you plan to create a larger carport.
  • Timber frames are less expensive and still have enough structural strength to hold your solar panels.

3. Determine the number of solar panels required for your DIY solar carport based on the size of your carport and the associated expenditures.

Step 3: Laying Concrete Footings

  • Before you begin, keep in mind that the foundation is critical for the stability of a solar carport.
  • Select a location for your solar carport. Mark the precise position of each timber post, making sure they are equally spaced and in alignment.
  • The depth of the footings should be approximately one-third the length of the timber post. This would be about 2.3ft deep for a 7ft post.
  • With 4″ ×— 4″ posts, the footing width should be around 8″.
  • Dig holes for the footings are required. Rough edges can be left since they increase friction between the posts.
  • In a wheelbarrow, prepare the concrete mix. Maintain a 1:2:0.5 ratio of one component of cement, two parts sand, and half part water.
  • Using gloves, pour the mixture into the holes. Finish this on the same day to guarantee consistency.
  • The drying time can vary depending on the type of cement used. Regular cement might take up to a week to set, but quick-set cement takes roughly 48 hours.
  • Keep the concrete moist for the first three days to avoid cracking. This can be handled by watering the footings every day.

Step 4: Setting up the Timber Framework

  • Once the concrete footings have dried, bolt the anchor bases to the concrete.
  • Sand your 4″ ×— 4″ posts properly before inserting them into the bases and securing them with screws.
  • Check that the posts are properly vertical and stable. Consider utilizing additional braces if there is any movement.
  • Although this step appears simple, accurately aligning posts can be difficult.
