Short answer: To build solar panel bases without pouring concrete on site, place precast concrete blocks as ballast. No formwork, no waiting for concrete to cure, and you can move them later. CPS offers 5 sizes, 7–175 kg. Quantity and size follow the solar installer's design; you can send the design to our sales team to review. Blocks with cast-in J-Bolts can be made to your drawing.

30 × 30 × 30	65
40 × 40 × 40	152

How many blocks do you need

The number of blocks and the size depend on the frame design and the number of panels set by the solar installer. You can send the design or site photos to our sales team to review.

Need blocks with J-Bolts or a long base

Standard blocks have no J-Bolt. If the solar frame must be bolted down, blocks with cast-in J-Bolts can be made to order, or made to your drawing
For panels laid in long rows, choose the long solar mounting base: frame legs fix onto one continuous base instead of individual blocks (see the drawing on the product page)

Also used as container supports

The same blocks support office container legs above the ground. Under normal load, use 6 blocks per container.
